The Hiding Place

 

For decades now, when gardeners needed a windbreak or a privacy screen they have resorted to planting hedgerow monocultures of a few relatively fast growing evergreen species, among them the Leyland cypress. For some who prefer a more formal, planned look, that plan has sufficed, but others might look at such a hedgerow as boring and as a lost opportunity to bring more wildlife into their gardens. Planting with wildlife in mind takes a generous spirit, particularly for the gardener who is also trying to raise fruits and vegetables for their own consumption. There are trade offs and compromises involved.

One of the problems with a hedgerow monoculture occurs when one or more of the plants dies, creating a gap that must then be filled with the same kind of plant, sometimes at considerable expense if the new plant is not to be too conspicuous by its smaller size. The gardener can feel trapped, and the trap can get more enveloping and add even more expense if the reason for a plant’s death is a disease or pest, engaging the gardener in an endless battle. Sometimes it can be a blessing when a disease or pest spreads quickly from one plant in the monoculture to the next, ending the battle with its consequent frustrations and expenses and presenting the gardener with a blank slate after a tree removal company has carted away the battlefield fallen.

Instead of persisting in folly and boring landscaping, a gardener might decide it is wiser and more interesting to plant rows or clumps of a diverse assortment of trees and shrubs, more closely imitating nature. The gardener might look for evergreen trees for year round screening for the gardener and cover for wildlife; deciduous trees which with their tall, rounded crowns fill visual gaps between the conical forms of the evergreens, and add nuts and acorns for wildlife food; shrubs and small trees both evergreen and deciduous which give fruits and berries in different seasons; and finally a water source, preferably running rather than stagnant. That’s a privacy screen for the gardener and a home for wildlife, and it isn’t only for large properties, since there are almost always dwarf or semi-dwarf forms of trees available.

Inviting wildlife into the garden this way means being willing to compromise on the amount of produce left for the gardener, and also means protecting vulnerable young plants from the very same wildlife. This is a microcosm and an imitation of nature, after all, and not truly nature. In nature the loss of a few sapling trees here and there to deer browsing is not necessarily a catastrophe since there may be as many more that will survive to maturity. But for the gardener who may have space to plant only a few trees, the loss of even one young tree is important. An example would be the gardener who joins in the effort to restore the American chestnut to the landscape and helps the cause by buying and planting a few saplings at home. Unless that gardener cages the chestnut saplings for the first two or three years of their growth, deer will come along and browse the foliage and rub  velvet off their antlers using the trunks of the saplings, debarking them. Caging is the only truly effective way to get deer to leave the chestnut saplings alone until they are big and strong enough to withstand their attentions.

On a small lot in particular a gardener should not expect to get very many fruits and berries for their own consumption. Birds love eating the same things, and they are outside all day every day, watching for ripeness, and when it comes the birds get to the fruits and berries very soon. Netting is a nasty business that tangles up birds and other critters, killing them, and it has no place in a garden planted for wildlife. Either be content with gleaning a few fruits and berries here and there, or build a small greenhouse to grow a few protected plants. Gardeners with large plots of land have more options, both for the wildlife and for themselves. Plant native plants when possible, because they are better adapted to coexist with native wildlife. Once there are birds and frogs and other insect eaters living nearby, the gardener may actually find fewer pest and disease problems in the rest of the garden, and that alone makes it worth the trouble of devising a landscape scheme more varied and interesting than a soldier row of Leyland cypresses.

Mulch too Much

 

 

As summer fades into fall, gardeners consider tidying their flower beds and around their trees and shrubs. Putting down new mulch can be part of this process, and it raises the question: How much mulch? Mulching two to three inches in total depth is plenty, making sure to keep the mulch from touching plant stems, and not piling up volcanoes of the stuff around trees. Any “professional” landscaping outfit or individual who does otherwise is acting out of either ignorance or the desire to sell more mulch, perhaps both.

Another consideration is whether to put down commercially produced mulch or wood chips. The term “mulch” can apply to organic or inorganic ground covers, such as pine bark, shredded hardwood, or stone. Wood chips are made from every part of a tree, and chips range in size from coarse chunks to finely ground pieces no larger than an inch. Gardeners should be careful to check the source of wood chips because they may have come from trees infested with beetles or borers, and if the chips have not been ground up finely enough or heat treated, then the insects may survive to cause further damage in new surroundings. Commercial wood mulch should not cause similar problems if the manufacturer has effectively screened it for pests, though gardeners should not apply it directly up to the foundation of a house, where it can serve as cover for termites already present in the soil.

 

A good rule of thumb to follow when applying mulch is not to apply it so thickly as to make it a heavy slog for the average happy garden gnome pushing a wheelbarrow.
