When Life Gives You Storm Damage, Make Habitat!

Dear readers, if I have not been writing much lately, here is just one of the reasons why:

halloween snow storm

The freak Halloween nor’easter that hit New England on October 29th dumped 18″ of wet snow on our farm, wiped out our power for nearly a week, and caused extensive damage across the region. We will be cleaning up from this for many months…

We lost several trees that we were very fond of, including the beautiful red maple above that was a focal point of our small farm. Here’s the tree in happier times:

Interestingly, this particular red maple was some kind of Acer rubrum cultivar, selected by plant breeders more for its beautiful glowing fall color than its ability to withstand freakish New England weather. We have a number of wild-seeded red maple trees on the farm that survived the storm intact. Those trees are really well adapted to early or late snow, and most of them just lost a few branches here and there.

One of the native red maples, just next to our driveway,  was completely topped completely:

But look at the habitat that was created from the storm. A brand new snag! Check out the pre-drilled woodpecker holes near the top. This red maple snag may be newly created but clearly it’s already been used by wildlife for years:

Conveniently situated with a clear view from the house, this is our new wildlife viewing zone for the winter of 2012. The snag may have to come down completely in future years — if it starts to lean over the driveway — but for now we’ll be able to watch the comings and goings of birds, squirrels and other wildlife making use of its many resources.

So the storm wasn’t all bad! Wildlife are grateful! Old trees and branches are part of natural ecosystems and support a huge variety of wildlife, from hawks, owls and bats, to lower life forms such as invertebrate insects, amphibians and even reptiles. In the spring, sapsuckers will drill the remaining living portion of the trunk for sap, attracting insects with a ‘sweet tooth’, many of whom will get stuck in the sticky sap and become food for birds.

But what to do with all those tree branches and brush that have fallen? If you have the room, use them to build a brush pile! We built what we consider the mother of ALL brush piles at the side of our pasture:

This (ahem) carefully constructed brush pile (aka Winter Wildlife Resort at Turkey Hill Brook Farm) features snug bedrooms with fragrant pine bough ceilings, a lovely screened-in sunroom with a southerly view to safely bask in the sun on a bright winter’s day, as well as several large, fully-stocked pantries. If you’re a chickadee, you’ll find plenty of hemlock and pine cones to pick at all winter long. A chipmunk looking for a safe spot for your stash of acorns? Plenty of safe cover plus acorns free for the taking. If you’re a ground-feeding  junco, hopefully you can forage for seeds around the edge of this brush pile and dive into it when the neighborhood cats come prowling. Any woolly bear caterpillars still looking for a place to hibernate can burrow into the dead leaves under the pile.

OK, I know that most built-up areas can’t support a brush pile of this size in everybody’s back yard, but even if you have a small area to work with, a more modest brush pile still works:

So if you’re faced with tree damage from the crazy weather we’ve experienced in the past year, remember that if life hands you tree debris, instead of burning it or sending it away with the trash, you can always just leave it alone. And call it a habitat!

Virginia Rose

Have you always loved roses, but hate the spraying, fertilizing, watering and pruning they require to keep them from looking a mess? Please meet the lovely Virginia rose (Rosa virginiana). Unlike its highly-bred, cultivated cousins (hybrid tea roses and modern cultivars of climbing roses) this native eastern rose is hardy to the coldest parts of New England, grows happily in almost any soil, needs little to to no irrigation except for rainwater, and blooms its head off through June with pink flowers with the most heavenly fragrance. Not to mention, their beautiful red fruits (hips) persist right through the winter, feeding birds and providing winter interest when the landscape is otherwise white and brown. What’s not to love?

Most Virginia roses bloom in light or medium pink, although there are white-flowering cultivars available too (I’ve not had good experience with the white-flowering form, however). Their flowers might not have the fluffy allure of the larger double-formed hybrids, but their single-flowering form makes them much more attractive to butterflies and other pollinators, who don’t have to fight their way through many layers of petals to access the sweet nectar and pollen at the center of the flower. And did I mention its fragrance?

When it’s happy, which is in any decent soil with good drainage and plenty of sunshine, Virginia rose will spread fairly rapidly within just a few years, so if you have a large area you’d like to fill in quickly with a wildlife-friendly native plant, Virginia makes a great choice.

In bloom, a pink tapestry of Virginia rose mingles beautifully with foxglove, cranesbill and other late spring bloomers and will form a low, thorny hedge that offers excellent year-round predator protection for the birds visiting your gardens. This sunny hillside of our farm was planted with a single container of Virginia rose in 2006, and by June 2009 it had happily spread to form a sizeable thicket:

IMG_3641 virginia rose thicket reduced

As you might imagine, its spreading habit (through underground roots that snake in every direction) makes Virginia rose unsuitable for small gardens, where its roots will eventually take over surrounding plants and form dense canes that shade them out. A better-behaved but just as pretty wild rose is Virginia’s closest cousin, Carolina or pasture rose (R. carolina) which spreads by slowly enlarging clumps rather than spreading roots.

In the thicket above, an annual mowing stops Virginia rose runners from spreading into the adjacent lawn, but you can also contain its advancing roots with a hard root pruning every few years with a sharp shovel. A driveway also makes a good boundary, as long as you don’t use large amounts of salt to de-ice your driveway.

Note: Please let it be known that I would dearly love for the above Virginia rose thicket to spread and cover the entire hill, but hubby has drawn a literal line in the sand (with rocks!) where his lawn cannot be further encroached! I am hoping he won’t notice the line has moved a few times

So planting Virginia rose in beds with other perennials is not a good idea, but in a new planting of a large area, you can interplant with self-seeding annuals, biennials or short-lived perennials to fill the bed for the first few years while the rose spreads….I initially planted the above bed with common sage, purple coneflower, cranesbill, foxglove, cosmos and cleome, and after 4 years, mostly only the foxglove remains in the area, probably because its seedlings are more shade-tolerant than the others. The others I have simply moved to other areas of the garden or given away to friends.

If you’ve grown roses before, you’ll appreciate that Virginia’s foliage is very resistant to most of the common diseases that disfigure roses. Like all roses (wild or cultivated), Japanese beetles love to eat its foliage, but if your plant is healthy and vigorous, it should shrug off any damage. These roses bloom in June in central Massachusetts, and Japanese beetles don’t tend to arrive in large numbers in our area til early July, so by the time the beetles start chewing, you should have other beautiful blooming plants to distract you from a few holes in their leaves.

 Virginia rose canes top out at about 4′, so you should never need to prune them for height, especially because you’d be cutting off one of the plant’s best features, its plump red hips that you barely notice until the first winter snows suddenly bring them to life:

The hips must be pretty sour to taste, because the birds don’t seem to touch them at all during the winter. They disappear around the beginning of spring here, so winter’s deep freezes must sweeten them up a bit, or else late winter birds are too hungry to be picky. I often see their thorny stems used as a temporary hideout by foraging winter birds, who get spooked by hungry hawks hovering around my bird gardens and feeders. The white background makes tiny birds much more visible to larger predators (my dogs will confirm this because they constantly mistake them for chipmunks!) but even a cat is unlike to risk those nasty thorns and go in after them…

If your garden conditions are boggy or wet, the best native roses for garden use are swamp rose (R. palustris) and New England rose (R. nitida), although these bloom a little later than the field roses in summer.

If you look, you may still find native roses growing wild in natural areas. More often than not, though, roses that you see in the wild are the invasive multiflora rose (R. multiflora), which is often assumed to be native but is an introduced rose from Asia that has been steadily overtaking old fields in New England for decades:

19-x Multiflora rose closeup cropped reduced Although birds do eat their berries, multiflora rose has a highly negative impact on its surroundings, forming enormous thickets that crowd out the native plants that underpin balanced and healthy ecosystems. Chances are, if you see a large, fragrant sprawling wild rose with white flowers and arching stems, it’s multiflora rose. Removing these from your property can be a great contribution to protecting local biodiversity…you can either replant with one of our native New England roses, or use the “wait, weed and watch” approach, which means simply rooting out any remaining multiflora canes that pop up over time, and allowing any native plants that are still hanging on to make a comeback.

If you try the wait, weed and watch approach, be prepared for a funny thing to happen. You’ll begin to notice an increasing variety of birds, butterflies and other interesting wildlife that visit your naturalized area, many more so than your more cultivated garden areas, and eventually you will realize that your wildlife garden, with all the life it attracts, is your most beautiful and favorite garden of them all…

Should I Pull This Plant?

I hear it all the time. “Should I pull this plant? I’m not sure if I like it…”  The answer usually is….it depends. I have some clients who are passionate about restoring their landscape with native plants in order to help rebuild lost or damaged local ecosystems. For them, the answer is easy. If it’s not native, yes, pull it up and replace with a native plant. But what if your property already has many nice (and expensive) landscape plants and you’re not sure whether they’re worth keeping? As a habitat gardener, you can decide whether to keep or remove a plant by answering a few key questions:

is it listed as an invasive plant in Massachusetts? If yes, definitely remove it to make room for native plants, who may be capable of recolonizing the area. Or, replace it with a native plant suitable for your garden conditions. Invasive non-native plants are a major threat to biodiversity and environmental health. Even if you don’t see a plant behaving aggressively in your own yard, many invasive plants are spread by birds eating their berries or seeds and pooping them into nearby natural areas, where they quickly form colonies that crowd out the native plants essential to local wildlife. See IPANE (Invasive Plants of New England) for the plants that are invasive in New England.chickadee magnolia

is it healthy without needing fertilization or regular watering? If so, it’s well suited to the spot it’s in and won’t need your constant fussing to keep it looking good.

Does it attract birds, butterflies or any other forms of wildlife? Do its flowers provide nectar and pollen for butterflies, bees, hummingbirds and other pollinators to use as a food source? Does it form nutritious berries, seeds, nuts or cones that are an important food source for many birds? Does the plant’s foliage feed caterpillars and other insects that most birds rely upon to feed their young? Does its structure and foliage provide shelter, protection and nesting sites for many birds and other wildlife?

If the plant supplies at least 2 or 3 of these last few attributes, it is wildlife-friendly and you should probably keep it. Its presence supports declining populations of birds and pollinators who help keep our environment in balance.

oie_IMG_5417On our property, we have several areas planted with Cotoneaster, (right) which is a low shrub often used as a groundcover planting in New England lanscapes. It’s not native here, and it’s not what I would call a spectacular plant, but I have never considered removing it because it has its benefits…it thrives along a brick walkway in dry, hot blazing sun without any care or attention from us except for a bit of occasional weeding. Its dense twiggy branching structure, especially when it’s pruned, is a safe place for overwintering songbirds to dive into when they visit our winter bird feeders. Its tiny pink flowers are a magnet to spring pollinators, who are in turn an abundant food source for migrating birds newly arrived from the south. In the fall, pollinated cotoneaster flowers form large red berries, which although I have never seen birds eating them, the berries persist right through winter and disappear in about March, so some hungry creature is eating them when food is scarce!

For a foundation or walkway planting, you can prune cotoneaster into an attractive low hedge that satisfies even the most formal-style gardeners. My own hubby, who loves a crisp, clean Zen-garden style of landscaping, that often – um – clashes with my own more natural style of gardening, loves our cotoneaster hedge because it gives him that controlled look he craves while satisfying my requirement that a plant in such a visible location should not just look good, but also support the wildlife we invite into our backyard habitat.
