Add winter interest to your gardens

Blah.  Blah.  Blah.

As you look out your windows onto a wintery scene are you missing the colors, shapes, and forms of your summer garden?ย 

No need.ย If you want to be delighted rather than depressed with your views, plan now to add some winter interest to your garden with color, texture, and form.

Crape myrtle’s exfoliating bark adds textural interest. 

Letโ€™s start with texture. Adding plants with interesting bark textures ratchets up the โ€œwowโ€ factor in a landscape.ย Personal favorites are the shaggy bark of river birch and the mosaic bark of crape myrtles. Both have striking multiple trunks and crape myrtles range from 3 to 30 feet to fit any landscape. Other trees have smooth bark, furrowed bark or bark like an elephantโ€™s trunk. Mix it up. The excellent book, โ€œDirrโ€™s Hardy Trees and Shrubs,โ€ includes bark photos in each plant profile.

With needles short or long, spiky, clustered or drooping, evergreen trees boast appealing texture. Seeing Norway spruceโ€™s kimono sleeves dusted with snow makes you really, really want one. 

But trees arenโ€™t the only plants that tout texture. Think shrubs, ornamental grasses, and perennials. I canโ€™t walk by a leatherleaf viburnum without stroking its coarse, deeply veined leaves.ย Ditto for hollyโ€™s glossy leaves.ย 

The seed heads of ornamental grasses and perennials also can add striking texture. The snow-capped seed heads of coneflowers and Brazilian verbena look especially fine. 

Now, letโ€™s pop some color into your winter garden.ย Youโ€™ll find it in the crimson branches of red twig dogwood and the berries of hawthorns, hollies, and winterberries. But red isnโ€™t the only color you can cultivate.ย 

Winterberry adds bright color to the winter landscape

Some junipers tinge purple in the winter or hold onto their summer blues.ย Tan ornamental grasses contrast well with snow and add movement when stirred by the wind.

Crabapples dangle yellow, orange, and red fruits while viburnums show off berries of red, purple, black, or blue.ย And most evergreens are, well, green.

Mother Nature stocks her palette with softer colors.ย Grey rocks sport green lichen.ย Wood ages from brown to grey.ย Use natural materials to add color and beauty to walkways, benches, fences, and accents.ย 

Suffuse your garden with your favorite colors.ย In the European garden Kiftsgate, the owners carefully placed splashes of bright blue. It adorns a bench, garden gate, and more to perfect effect.ย So grab your paintbrush.ย 

Now, letโ€™s talk form.ย Mixing shapes creates a well-designed landscape, but those shapes are most noticeable in winter when deciduous trees have dropped their leaf dresses. What do the bare bones of your landscape tell you?ย Look for shapes โ€“ round, square, triangle, oval, pillar, vase, and teardrop โ€“ and add whatโ€™s missing.ย 

If your landscape is filled with lollipops โ€“ round balls on sticks like maples โ€“ then add something layered and wider like a dogwood, triangular like a spruce, or columnar like an arborvitae. Weeping forms improve every garden.

When garden designers tell us to plan for the view, they mean the views from both the inside and outside.ย  So look out your windows and imagine what you want to see. Then make it happen.

Fine-tuning your indoor plant lighting choices

This is the final article in our four-part series about indoor plant lighting. You can also read the first, second, and third articles.

You may see two other details provided in lamp specifications aside from the terms introduced in my last installment. They are not critical factors but can influence your satisfaction with how the lights look by themselves, and how plants, decorative pots, and other objects look underneath them.

The appearance of plants under the lights is not only important for aesthetics, like seeing the true colors of blooms, but also for detecting leaf discoloration, which can be a key symptom of malnutrition, light stress, or pest or disease damage.

Color Rendering Index (CRI)

While this doesnโ€™t affect actual light intensity, it does impact our perception of how colors will look under a light and is a matter of personal preference.

On a scale of 0 to 100, the higher the CRI value a lamp has, the more accurate the colors will look compared to viewing in natural light. At the low end of the scale, colors are lackluster (desaturated) and less distinguishable from each other. Since incandescent, fluorescent, and LED lights all produce light by different means, they have different CRI ranges, though improvements in technology are closing this gap. Ideal ratings are in the 80s and above, with the 90s considered โ€œhigh CRI.โ€

Winter Pruning with Andrew Ristvey – The Garden Thyme Podcast

Although it may be cold and dreary outside, itโ€™s the perfect time to take inventory of your deciduous trees and shrubs to see which plants would benefit the most from pruning. In this month’s episode, weโ€™re sitting down with Extension Specialist in Commercial Horticulture, Dr. Andrew Ristvey. Dr. Ristvey is giving us the ins and outs of winter pruning.ย 

We also have our:ย 

  • Bug of the Month  (Winter Stoneflies) at 37:30
  • Garden Tips of the Month at 45:55
  • Native Plant of the Month ( American holly)  at   49:00

Here are some great resources to learn more about pruning:

Peat-free potting mixes

Sphagnum peat moss is valuable in horticulture because its fibrous structure helps it retain a lot of water and air while draining excess water. This has made peat a primary ingredient of soilless growing media (potting mix) around the world. These stable, light-weight, and porous products have been filling the benches, flats, and containers of greenhouse and nursery operators and flower and vegetable growers for decades. Youโ€™d be hard-pressed to find a gardener who has not benefited from soilless potting mixes for starting and growing plants, inside and outside.

What’s the problem with peat?

Peat is an organic substance formed from mosses, reeds, and sedges that accumulates and decomposes very slowly in waterlogged soils (bogs). Peatlands hold 30% of the earthโ€™s soil carbon and occur mostly in cold, temperate regions. โ€œPeat mossโ€ used in horticulture typically refers to mosses in the Sphagnum genus.

The problem with peat is three-fold: stripping off peat from peatlands disturbs complex ecosystems; excavation releases enormous amounts of CO2, a major greenhouse gas driving climate change; and demand for peat-based soilless media is growing.

For decades, there have been calls to conserve the U.K.โ€™s dwindling peatlands. Timelines are in place for soon phasing out peat as a growing media for gardeners and commercial growers. Most sphagnum peat is from Canada and there are no indications that Canada, with its vast peat reserves, will follow suit. But public demand for peat-free alternatives will drive the industry to develop new products.

Reducing the use of peat in horticulture will mitigate climate change and increase reliance on local materials as peat substitutes.

Vermicomposting: turn food scraps into compost indoors

Backyard composting isn’t an option for everyone. If you live in an apartment or condominium, worm composting or vermicomposting is a simple and inexpensive method you can use indoors to turn food scraps into compost for your houseplants or garden. Composting food scraps keeps organic waste out of landfills and reduces climate-warming gas emissions too.

In this video, Master Gardener Susan Levi-Goerlich demonstrates how to set up a basic vermicomposting system at home.

What’s going into Erica’s garden this year?

I have ordered (and received) my seeds! I may end up with more, at seed swaps and from friends, but I’ve made the basic purchases to fill in needs. For the first time in ages, I didn’t order any tomato seeds–I know, shock, horror–but I still have plenty and I’m going to cut back on the number of tomato plants this year in favor of peppers and other summer crops. Will everything I’m thinking of planting actually fit, either in my community garden plot or in containers at home? Only time will tell.

Anyway, I thought I’d give you all a glimpse into the reasons I chose a few of the plants I plan to grow. Below I will profile Amara Ethiopian Kale, Yellow Cabbage Collards, Dario Cocozelle Zucchini, Zipper Cream Cowpeas, and Nadapeรฑo Peppers. I’ll link to the companies I ordered them from so you can read more, but doing so is not an endorsement by University of Maryland Extension.
