Garden Prep Work

A chore worth doing, is to cut low-hanging branches off your shrubs. When branches are scraping ground, you have a hard time raking out debris; and when you rake under your shrubs, your garden’s appearance is improved—but also, pests and funguses are reduced. You may find some branches that are under piles of leaves have produced roots. This is the principle behind layering, the name for propagating shrubs by deliberately burying their branches. Above are two azalea starts. The parent plant gets assaulted by mites every year, although it comes back in the spring and blooms.

Planting in shade will sometimes ward off pests that thrive in bright sun, so I’ll find out if these do better in my back yard under trees. I noticed this phenomenon with a green beetle that used to devour my sunny phlox, but never bothered the shady ones.

Here is my seed-starting arrangement. Gardeners who grow their own plants tend to hang onto their lights forever, but we’re living in a good era for upgrading. LEDs are better than fluorescent tubes, and don’t create the same disposal issues because they last so long—these I’ve bought this year, at the photo’s right, are linkable, so I can use fewer plugs in my surge protectors. They draw 45 watts, times six (plus the old ones) still well below a household outlet’s capacity. I use daylight, though I’ve seen advice to mix daylight with warm bulbs for the full spectrum. I don’t, and my seedlings all do fine. The coleus and impatiens, seen on the left, are cuttings from plants I brought indoors last fall. These two species root so easily that even stripping the leaves from the stem isn’t necessary. They will sit wilted for a week and then their leaves will plump up again.

I use peat pellets to start my plants, because the peat is resistant to fungus, so the seedlings do better achieving their second set of leaves without damping off (a fungal disease). But the following year, I have to dig up the remains from my annuals. (Perennials just grow through the netting and carry on.) This year, since I’ve been improving my front border with a double-height edge of blocks, it’s occurred to me these old pellets would work well stuck in gaps and spaces, where the netting will prevent water from carrying away garden soil, a good use for last year’s leavings.

An idea I have about what to do with an old furnace filter. The wire mesh holds the cobblestones in place, and the cardboard should decompose into the soil. The problematic item is the fiberglass filter. Landscape fabric is a polypropylene, so its decomposition into the environment has some impact, although it’s considered outdoor-safe. Fiberglass is substantially a plastic product, too, and is used for pool and pond filters.

The alternative to finding a use for old furnace filters is to add them to landfills. This arrangement could be covered with sand, pebbles, or mulch, and the filter would block weeds, while its decomposition ought to be well contained. Let me know if you have more information.


A last idea for reusing plastic. The above is a large cat treat cannister. I buy lettuce for sandwiches, not salads, so I need it to last a few weeks. Transferring lettuce from the store packaging to this upright configuration, then adding paper towels top and bottom, really helps my greens last a long time.
