Late-Autumn Garden Chores

Posted on by jeanmariemorelli.com

Late autumn usually brings the most precipitation to Port Townsend and the eastern part of the Olympic Peninsula. Atmospheric rivers dump rain. Strong winds blow and fallen leaves swirl. The sun is low in the sky.

The winter vegetable garden is producing, but most growth happened before the fall equinox. Garden beds covered with hoops and floating row covers will be protected from frosts. Fresh salad greens, kale, Swiss chard, and leeks  can be harvested throughout the winter. Monitor vegetables for slugs and cut worms. The wet weather favors slugs and snails. Get them now and there will be less generations come spring. Also cut worms are a problem and can be found during routine weeding.

Fruit Trees

Keep the base of young trees free of tall grass. Better yet, place mulch around the trunks. Winter is the time when voles chew bark and roots. If you have a serious vole problem wrap the trunks with hardware cloth to prevent the rodents from gnawing the bark. Some gardeners even use pea gravel as a mulch to discourage voles.

Late winter is a better time for pruning apple and pear trees, ornamentals and raspberries. The reason not to prune now is because we could have a warm, sunny spell in January that could encourage plants to grow—only to be blasted by a deep cold in early February. Better to wait until mid- February for most pruning. Because wet weather promotes bacterial and other diseases, many gardeners prune plums and cherries after flowering during a sunny spell.

This is a good time for large garden projects that warm the body. Pushing wheelbarrows of manure, woodchips, and  making large compost piles. Building planter boxes and retaining walls. Cutting down dead trees or cutting up branches for firewood or hauling them to the yard-waste facility. If you live in the woods, think about a larger tree-free area around the home as future fire-prevention.

Going within

And then there are times to slow down, take walks and notice the birds. Different birds are here for the season. Watch for Pacific wren, red-breasted nut hatch, northern flicker, pine siskin, golden-crown kinglet and spotted towhee.

Winter is a good time to dream about the garden. A garden mentor once said that the garden is forgiving—we can always try again next year. It’s a time to think about rearranging perennial beds and planting more drought tolerant flowers. Or perhaps it is time to think about  simplifying a high maintenance garden. For some gardeners seed catalogs arrive in January and planning the edible gardens begin. Now you can think about how you can extend the season or create a garden sanctuary.

Gardening for the Senses

Posted on by jeanmariemorelli.com
Plants with textured foliage invite us to touch or pluck a leaf and stroke it, even caress our face!

Gardens can stimulate or relax us by how they influence the five senses. A relaxing ambiance can come from blending in with the existing natural environment. When we are alive to our senses, we are in the moment. The frargrance of a rose or the soft texture of a leaf slid across the face, contrasting colors in the garden, all influence us through our senses. A repetitive pattern has a soothing or harmonious influence.

Gardens that stimulate and bring the energy up often have bold colors and strong scents. Patterns that contrast and colors that contrast are powerful. Think magenta and orange flowers with combined with chartreuse foliage; ornamental grasses next to large-leaf shrubs like Fatsia; canna lily with ornamental onion, the list goes on! Whimsical garden features like colored globes or blown glass spikes and sculptures with mirrored surfaces all add to an energetic feel. Mahonia media and unusual hebes along with weeping dwarf conifers all add an element of excitement.

Sound

Most of us in Jefferson County are fortunate to live where it is quiet enough to hear natural sounds: wind through conifers, rain on roofs, treefrogs singing, and geese flying overhead. We can create or muffle sounds in the garden. A water feature outside our open window will bubble, gurgle and splash.

Birdsong is another feature we can add to our garden by offering habitat, water and food. Humans have evolved with birds—when they are singing, all is safe. The melodious calls of songbirds encourage us to relax.

Large ornamental grass like Miscanthus grouped together can whisper in the wind. Bamboo make a soft sound as the wind passes through.

Windchimes create different moods. Determine if high-pitch tinkling sounds or deeper, resonant bass notes bring you joy. Listen to different ones to choose. 

Science has shown how auditory input impacts us, based on variation of pitch and length of time the sound The rhythmic sound of water on the shore is similar to the sound of humans breathing thus it is often soothing. When we hear many sounds at once it can be discordant and confusing. We can create a peaceful soundscape by muffling unwanted sounds with hedges and berms.

Scent

Flowers come to mind first when we think of scent—roses and lavender. Other scents include volatile oils in foliage and resins in conifers. Ambient temperature affects how strong the scent is. A sunny day will bring out the aroma of ponderosa pine bark or the resin dripping from a spruce. Walkable groundcovers are prostrate plants that can be placed  in pathways or between stepping stones—in the shade Corsican mint and in sunny spots plant caraway thyme or pink ripple thyme. As you walk past fragrant plants along a pathway brush against them or let your hand glide over the surfaces. Better yet, pinch a bit and bring it to your nose, inhale deeply and set the bit in your pocket.

Scented plants along the path are easily pinched as we walk by, sniffed and placed in one’s pocket

Touch

Don’t forget the tactile dimension of the garden. Many gray foliage plants have textured surfaces of fine hairs to reduce water loss. Lambs ears, Stachys byzantina; giant silver Mullein, Verbascum bombyciferum; and the artemisia are ever so soft. Ferns have feathery foliage as does dwarf Japanese plume cedar, Cryptomeria japonica elegans. Moss is plush.

Taste

Edible flowers in the garden add an element for our tastebuds. The sweet-licorice flavor of anise hyssop, the peppery bite of nasturtium blooms, or the citrus notes of lemon thyme, all add to the multidimensions of the garden.

September Garden Chores

Posted on by jeanmariemorelli.com

The fall equinox is approaching quickly. The weather is changing. Autumn offers opportunities to plant and transplant; the soil retains warmth longer than the air can—a perfect combination for encouraging root growth. With cooler temperatures and short day length, plant growth slows. The roots have a chance to get established without the additional stress of transpiration or pumping water through plant and out the leaf surfaces.

Autumn is a great time to make compost piles with debris from the vegetable garden, perennial plants and deciduous leaves. Some people prefer to leave the dead foliage and seed heads for spring removal allowing insects and birds food and habitat overwinter. Try it, but note that adding garden clean-up to normal spring chores might overwhelm some gardeners.

Edibles

Fruit trees: Most tree fruits are ripe when they come off easily by lifting and twisting the fruit. Take care not to break off the short branch with buds known as a fruit spur. Cut open an apple —ripe seeds are brown. Pears are picked when they are still hard, before they are fully ripe. They soften from the inside out. Asparagus: Let the fronds remain and turn yellow. Cut them back to the ground after a hard frost. If you have an excess of produce, try making sauerkraut or kraut-chi.

Soil Fertility

Soil Samples: Every couple of years it is worthwhile to take a soil sample and get it tested. Although Jefferson Conservation District no longer handles soil testing, they do lend a tool for extracting clean samples and lab suggestions including A&L. I’ve had good luck with Peaceful Valley Farm Supply.

Compost: Build compost piles in bins or free-standing rectangles. All the autumn decaying foliage from the veggie garden, perennials, and deciduous leaves. Add a source of Nitrogen: manure; powdered fish or bloodmeal; or urine.

Mulch shrubs and garden beds for winter protection and weed suppression. The increased organic matter that will eventually feed the soil ecosystem.

Cover-cropping: After removing spent vegetables, rake the soil, add seeds of clover,  field peas, oats, rye, vetch, or fava beans. More information from WSU All seed available at Chimacum Corner.

Pests

Yellow jackets

Recognize yellow jackets and their underground nests. In the autumn listen for buzzing if there are more than two yellow jackets in a location, step back and search the ground for more. Yellow jackets can sting repeatedly. By contrast, bees avoid stinging because it is lethal, it rips out their stinger. Learn to distinguish them.

Spring Bulbs

Plant bulbs and corms now for spring bloom. The earliest bloomers are the small bulbs: snowdrops, crocus, chionodoxa, Siberian squill and winter aconite. Select bulbs that are firm with no signs of injury or mold. If one bulb is lightweight compared to  others, discard it. Plant with root side down and pointy end up. Plant at depth three time the length. Small bulbs often are earliest. See Royal Horticulture Society for more information.

Grain Amaranth

Posted on by jeanmariemorelli.com
Abundant Life Seed Foundation Gardens 1999

Tinker was involved with Abundant Life Seed Garden from its inception in the 1980’s until 2001. She and John Gilardi were garden managers in the latter years. In the above photo, Tinker and an apprentice named Nicole are stripping the flower heads of dried amaranth to remove the seeds. Next steps include winnowing and screening. Later amaranth was one of the crops Tinker experimented with in the dryland farm project.

 Amaranth’s importance is twofold—its super nutritious and easy to grow.

Unlike grains, the seeds of amaranth contain all the necessary amino acids. The protein content is 16 percent, more than rice or wheat. Like quinoa, this offers complete protein for vegans. Amaranth is considered a pseudograin (only plants in the grass or Poaceae family are considered true grains)

Grain Amaranth comes from one of three species. All are white-seeded whereas the leafy greens amaranth tend to have black seeds and may become weedy.

A. cruentus, Purple Amaranth: Day-length neutral and most widely adapted. Typically white-seeded from Mexico, this is made into “Alegria”, the popped seeds mixed with molasses pressed into a small cake or bar.

A. hypochondriacus, Prince’s-feather is day-length sensitive. I know little about this species.

A. caudatus , Love Lies Bleeding is native Peru. Sometimes called Inca wheat, it is an important staple in the Andes.

While young foliage can be confused with weedy amaranth, (A.hybridus, A. viridis, A. retroflexus. A. spinosus.) grain amaranth has apical panicles, or seed heads forming only at the top. Grain amaranth can withstand drought conditions because their roots can grow several feet deep.

Early strains of A. cruentus were cultivated as far back as the time of the first maize in Oaxaca. The Jardin Etnobotanico de Oaxaca includes a section of early cultivated food crops. I was lucky to volunteer in the garden during the winter of 2019 and had the privilege to work with Roberto Chavez Rendon. Here he is with an early strain of Amaranthus cruentus.

Open-pollinated grain amaranth species can be variable. Many selected strains have full heads laden with seeds. Seed breeders are selecting for shorter plants that don’t shatter. University breeders are developing F-1 hybrids for food production.

Although claims vary, Amaranthus cruentus and A. hypochondriacus were cultivated before 1,000 BC in Mexico. Grain amaranth was an important food source from the Aztecs until European missionaries put a stop to eating or using amaranth in ritual. It is again popular and is best known as “Algeria” , the popped seeds mixed with molasses and pressed into a small cake or bar. An NGO in the Etla Valley of Oaxaca, Puente a la Salud promotes food sovereignty with a focus on grain amaranth not only for cakes but to add as an ingredient in many dishes ground into flour; boiled and used as a thickener in soups; toasted and popped as a cereal. They encourage farmers to grow the crop and teach communities how to make appropriate tech ovens and poppers for cottage industries with amaranth.

Amaranth has the potential to be an important crop as we move into greater climate change. It is drought-, heat- and pest-tolerant. The nutty flavor can add more nutrients to oatmeal or ground into gluten-fee flour. Try growing this beautiful plant in the edible landscape, or in rows for production.

Joe-Pye Weed: Pollinator-friendly Perennial

Posted on by jeanmariemorelli.com

My earliest memories of Joe-Pye-Weed are from the coastal town in MA where I grew up. In late summer the purple flowers towered over other plants growing wild in what we then called swamps. I would bicycle down the country lane and cut stems of the flowers to make dried flower arrangements. Joe-Pye-Weed was likely named for  Joseph Shauquethqueat, a Mohican medicine man who cured settlers.

Although the plants are found throughout the East Coast on moist sites, they can tolerate drought conditions. For this reason, they make a good addition to our landscapes. A myriad of hybrids is available for this popular genus. Formally known as part of the genus Eupatorium, botanists have recently reclassified this group into a distinct genus, Eutrochium.

One hybrid has been bred to grow only 3 feet tall. They can grow in part shade and look more robust with regular watering. If the intention is to encourage them to be drought-tolerant, plant them in lots of compost. After three years divide the plants. They will ocassionally reseed, mostly they spread slowly from the crown.

The 6 ft tall hybrid plants I have were divided from a friend’s clump. The hollow stems are a deep purple and after the perennial is finished for the season, these stems make excellent disposable tubes for Mason bee homes!

Landscape uses:

Consider this for outside the deer fence. Eupatorium works well with Miscanthus, perennial sunflower and cardoon for a dramatic late summer perennial display. After growing vigorously in spring and summer, they come into their own in August and September. Rain gardens need plants that can withstand inudated soils.

Other Uses

If you raise mason bees, see my earlier post, then the dried stems of this plant make great disposable nesting tubes for the mothers to lay their brood.The right photo shows the Joe-Pye stems on left and the purchased tubes on right.

Matilija Poppy

Posted on by jeanmariemorelli.com

Romneya coulteri

This beautiful grey-grey foliage plant with fragrant large white poppies does best where it has room to spread. It is both drought tolerant and—knock on wood—deer resistant.

Matilija grows well on the loose soil of landslides. I planted some on a mound about 20 years ago and rarely weed it. After a time, the Nootka rose spread across the mound pushing out the poppy. Not much can hold its own against Nootka rose. (That’s why I only suggest it for creating wildlife hedges where it will be kept in check by mowing or weedeating lawns and fields.) Matilija poppy migrated over to a pile of soil and rotting sod. Last year I had a dump truck load of horse manure delivered near the Matilija planting. Some of the plants were buried in the manure. Instead of suffering, the plant spread throughout what was left of the manure after I moved most of it.

Description

  • Perennial flower growing 3 to 6 feet tall
  • Gray-green foliage
  • 4”-8”  fragrant flowers. Described as fried-egg flower

Growing requirements and care:

  • Full sun
  • Drought-tolerant once established
  • Soil: flexible, needs good drainage
  • Cut back to the ground in late fall

Matilija Poppy spread to adjacent aged-manure pile. Wild mustard’s yellow blossoms in the middle of plants.

The Chumash, an indigenous tribe of central -southern coastal California, values the antimicrobial properties. In fact the name Matilija comes from a Chumash tribal leader. The plant’s alkaloids and other secondary substances make it useful for sensitive gums and preventing plaque. Herbalist Micheal Moore describes Matilija as a good first aid plant: the foliage makes a good external wash for sunburn, and inflammation from allergic reactions. At one time this plant was seriously considered as the state flower of California.

In the landscape, plant this majestic plant with other tall drought-tolerant ornamentals like Miscanthus and cardoon. In the foreground use Russian sage, and red hot poker. Once established these are all deer-resistant.

July in the Garden

Posted on by jeanmariemorelli.com
Oceanspray, Holodiscus discolor has cascading clusters of tiny cream-colored flowers.

Summertime has arrived on the Olympic Peninsula’s rainshadow! Native shrubs like Oceanspray, Holodiscus discolor and Hardhack, Spirea douglasii are blooming. Others are fruiting: salmonberry, thimbleberry, and red elderberry The garden is filling out with lush greens, and warm-season crops are starting to develop and mature. Just yesterday I saw a garter snake with a big black slug in its mouth.

Edible Garden

Winter garden: Select beds that have finished producing and replenish with compost. Rotating crops prevents diseases from building in the soil.

Time to direct sow brassicas and greens, beets and carrots. Varieties: Purple sprouting broccoli, Lacinato and Red Russian Kale, Early Jersey Wakefield cabbage, Winter Density lettuce, Abundant Bloomsdale spinach, Bolero carrots.

Make sure to leave room for your garlic crop that can be planted in November.

Tomatoes: Remove suckers and continue staking.

Weeding: Make a quick pass once a week to eliminate weeds. Some weeds can be companion plants, however they also compete for nutrients, water and light.

Curing garlic: Harvest garlic bulbs when 4-5 leaves are still green, taking care not to damage them. Over-watering or leaving them in the ground too long causes the bulbs to split or become prone to disease. Fresh garlic is fragile. Clean the garlic by gently pulling down the top leaf and removing it from the bulb. ( If the leaf has signs of rust, be sure to throw away the skins instead of composting to prevent spreading the spores.) Brush soil from roots.Drying in a well-ventilated place takes a couple of weeks. Check the stems and when no green remains inside, they are safe and should store well.

Strawberries: Renovate June-bearing varieties (not the everbearing, day-neutral ones). Cut to 2-3 inches. Mowing can accomplish this. Cut out and remove weak and crowded plants. Fertilize with a balanced natural blend like Down To Earth.

Flowers: Save seed from annuals and biennials including: nasturtium, bachelor buttons, foxglove, calendula and bread-seed poppies, cosmos. Dry them in a cool dark place and label the envelope with plant, and date.

Landscape

Time to review the garden. If some plants didn’t make it after the last couple of years of climate ups and downs, maybe replacing part of the landscape with natives could be on your horizon. If you have lots of space maybe it’s time to consider planting a hedgerow that will help slow the wind or screen the road.

Bulbs: Order bulbs  in the next few weeks to plant in the fall. This is especially true if you want to plant some more unusual bulbs. When they arrive check the bulbs to ensure there is no disease or damaged bulbs. Store them in a cool dark place until you are ready to plant. I often order from Johnny Scheepers. Another company, that is good and local is RoozenGaarde.

Irrigation: Determine which plants need extra care and keep their roots growing. Many established shrubs won’t need any water until August, but in the first couple of years a plant will develop nicely and be healthier if it is watered regularly. If plants look weak or diseased, give them a boast with compost and liquid seaweed fertilizer.

Lawns: Port Townsend homeowners have long had an unspoken agreement that green lawns are not a requirement for a beautiful landscape. A well-kept yard is often mowed until mid-July and then the grass goes dormant and the hawkweed or dandelions provide food for pollinators. When the autumn rains return, our lawns green-up again. At that time, spread dolomite lime. This provides calcium and magnesium as well as making the soil less acidic and more inviting for grass. In fact, many people prefer not to have lawns. But if grass is already there, allow it to go dormant.

Caring for English Roses

Posted on by jeanmariemorelli.com
English Rose, Roald Dahl
Roald Dahl , English shrub rose bred by David Austin

This post focuses on modern shrub roses bred by David Austin, a premiere rose breeder who introduced over 190 cultivars in his lifetime. Known as English Roses, these plants are crosses of old garden roses with modern hybrids. ‘Old Garden Roses’ originated before the 18th century. Examples  of OGR include Gallicas, Albas, Bourbons, and Damask. Unfortunately, these incredibly fragrant roses only bloom for a couple of weeks once a year.

Modern roses include hybrid tea, polyantha, and floribunda, shrubs and climbers. Most modern roses are repeat bloomers in six-to-eight week cycles. Many of the hybrid roses are prone to disease and require a stringent spray regime to keep them healthy. Modern shrub roses have been bred from old fashioned roses with the added features of disease resistance, repeat blooming and a wider range of colors. These roses have a more natural form of arching canes with many flowers whereas hybrid teas and floribundas have a stiffer form. Long-stemmed florist rose are usually hybrid tea.

English shrub roses come in all different forms from peony-like full blooms to simple single petal flowers. Other shrub roses include all the rugosa roses, wild roses like our native Nootka rose and many others. I don’t have time here to do these roses justice!

Cultivating Roses

Provide good drainage and fertile soil with plenty of compost. Six hours of full sunlight will allow the roses to flower fully. Water weekly at the base of the shrub. Mulch to conserve moisture.

Deadheading is the term for removing spent flowers. Removing the first flush of blooms not only encourages more blooms but also helps to shape the shrub into a graceful form. I use Felcos #2, but any by-pass clippers work well. Sharpen the blade and then and sanitize it with hydrogen peroxide or alcohol. Always clean before starting to prevent the spread of disease. If you note disease where you need to prune, wipe the blade frequently. Removing the spent flowers prevents the development of rosehips and seed formation. Resist the urge to prune immediately below the spent flower; this results in dieback, stubby dead stems. Pruning at a leaf with 3-leaflets results in dog-legs—many spindly short stems. Instead, look for a thicker stem and make the cut just above a leaf with five leaflets. This encourages robust flowers on longer stems, perfect for cut flowers.

Even though English shrub roses are disease-resistant, they can still suffer from black spot. This fungal disease spreads by splashing water. Irrigate at the base of the plant and handpick diseased leaves and dispose of them. Make sure their is plenty of air circulation. If you need to spray, Safer brand has a fungicide. In the autumn rake and destroy all fallen leaves. If autumn is not getting gradually colder with light frosts, monitor the rose. If it continues to flower into October, stop deadheading and allow rose hips to form; the enzymes and hormones might trigger a dormancy response. By early December, strip the leaves to force the rose into dormancy. If we suddenly get slammed with an arctic blast, it is better for the plant to be dormant. Pruning is best done in February—something for another post.

Groundcovers for Sustainable Gardens

Posted on by jeanmariemorelli.com

Sometimes called ‘living mulch’, there are many reasons to choose groundcovers, from covering challenging slopes; to reducing garden maintenance and water consumption; to simply knitting together the landscape. They offer excellent solutions to landscape challenges but groundcovers are not maintenance-free.

Woody Groundcovers

A popular native woody plant is Kinnikinnick, Arctostaphylos uva ursi. Another is Cascade mahonia, Mahonia nervosa. Other standard choices are Taiwan Bramble, Rubus calycinoides and  Pt. Reyes Ceanothus, C. gloriosus.

Emerald Carpet or Creeping Taiwan Bramble, a drought-tolerant plant

As these plants get established they need regular weeding, especially to prevent perennial weeds from getting a foothold. Fertilizing with compost or dry organic blends encourages the plants to grow. Mulching with woodchips or arborist chips reduces the need for watering. Cover bare ground with 2-3 inches of mulch, but don’t bury the crowns (where stem meets root) or go back after and brush mulch away from the crown. The very fastest groundcovers, especially those planted closer than the recommended spacing will not need much additional mulch. But slower groundcovers like Kinnikinnick or bearberry cotoneaster (C. dammeri ) will need more mulch in about three years.

For  woody groundcovers to look their best, prune once or twice a year. Prune back leggy stems to make denser coverage. (The principle is the same as tip-pruning house plants or perennials. It works by removing the plant hormone or auxin in the stem’s tip that maintains apical dominance.) Also, if your goal is a carpet effect, prune out vertical branches.

Herbaceous Groundcovers

These plants are not as tough as woody plants. If the foliage forms dense mats often this shades the soil and prevents weed seeds from germinating.

The smaller the foliage the more work to keep out grass and tiny weeds. If your garden is on a city lot then tiny foliage can work, just plant smaller groupings. There was a time when many people planted  chamomile or woolly thyme as small lawns, however they require regular weeding. If you plant lots of annual flowers that readily reseed themselves, herbaceous groundcovers with tiny foliage will take much more work to maintain because they will easily harbor germinating seedlings.

Natives include evergreen coastal strawberry Fargeria chiloensis, inside-out flower, Vancouveria hexandra and redwood sorrel, Oxalis oregana,  and stonecrop, Sedum spathufolium. Non-native groundcovers include many Epimediums, and Geraniums. A low maintenance herbaceous groundcover for shade is hardy geranium or Geranium macrorrhizum, especially the magenta pink ‘Bevan’s Variety’ makes a dense mat of foliage that is deer-resistant. It does require a little water during dry summers.

Plants don’t have to form low carpets to be a groundcover. Distinctive foliage is a good reason to mass plants together. Under conifers the western sword fern is attractive. Larger perennials like Corsican Hellebore, Helleborus argutifolius make a bold statement. Pools of ornamental grasses offer ribbons of texture that can ripple in the wind.

Goumi in my garden

Posted on by jeanmariemorelli.com

One of my favorite permaculture shrubs is Goumi, Elaeagnus multiflora. This multifunctional plant is easy to grow! The fragrant tiny yellow flowers bloom in April, followed by astringent and sweet fruit by the end of June. In 2018 I ordered plants from One Green World and they recommend planting two varieties, so I planted two Sweet Scarlet and two Red Gem. The former is more robust with dense foliage that hides the fruit from the birds whereas Red Gem has a more open framework, with less foliage and is more productive. If you have limited space and prefer to cook the fruit with a sweetener, then Red Gem is a winner. I mostly eat the fruit raw and share the crop with birds. For the sweetest flavor wait until the fruit is a deeper red.

The genus Elaeagnus is recognized for having a symbiotic bacteria, Frankia that grows in the soil and fixes nitrogen from the air, making it available to the plant. I prune Sweet Scarlet several times a season and use the leafing branches as compost.

Goumi, an Asian native has been cultivated here for at least one hundred years. In Japan it is known as natsugumi. The fruits of this shrub are high in lycopene I wrote a more thorough account here
