Indeed, the Seeds of Weeds Will Breed
Jul 30th, 2009 by Shari
While weeds always pose a problem, they’re especially bothersome when you’re trying to raise a garden and conserve water at the same time. Yes, it’s one of those cruel tricks of nature that you can nurture a plant, giving it everything that it needs to grow, and it can still wither and die; yet, at the same time, weeds seem to thrive no matter what, stealing nutrients and water from the plants you’re trying to cultivate.
Most of us spend a great deal of time trying to get rid of weeds, when we’d much rather be lying in our hammocks, relaxing on our patio chairs, or lazing in our porch swings. There are many methods for getting rid of them, including pulling them up, digging them out, spraying them with herbicides, and putting down weed barriers; and each has its advantages and drawbacks.
Barriers, for example, which are generally made of fabric or black plastic, control weeds by blocking the sunlight from their seeds, and preventing them from establishing roots. The fabric types allow a certain amount of moisture and air through to the plants’ roots; but if weed seeds land on them, they can take root right through the fabric, become tangled in it, and cause it to tear when you try to extricate them.
On the other hand, as black plastic is impervious to the weed roots, it is equally impenetrable by the water, sunlight, and oxygen that plants need. If you put holes in the plastic to benefit the plants, you break down the barrier for the weeds as well; and if even one weed sheds its seeds, you’ll end up with a ton of them. Moreover, even moderate rainfall can wash away any mulch that you have put down over the slippery plastic surface. So, your best bet is to use the fabric for flower beds, and the plastic in areas that you wish to keep 100% weed-free.
Using mulch, on the other hand, is not only a good way to inhibit weed growth, but, with the many hues and varieties in which it is available, it can add color and texture to your landscaping, and even complement your outdoor furniture. Mulch also insulates the soil, protecting delicate roots from being compressed by foot traffic, keeping bulbs from flowering too early in the season, and conserving moisture by slowing evaporation.
Mulch should be applied in four-inch layers over flower beds, with the areas around the plants thinned to about two inches. Keep it from direct contact with your house, and with tree trunks, because it encourages decay. Like everything else, it needs some maintenance. For one thing, because mulch erodes and blows away, it has to be replaced every so often.
Another thing that’s a bit inconvenient is that you must remove leaves from mulch in the fall, and keep grass clippings from shooting into it when you mow your lawn. Otherwise, they will decompose in the mulch, inviting weeds to seed and breed – indeed!
