What is a weed?
May is planting month – and the beginning of weeding season. Gardeners take the good with the bad. Off we go digging, planting and weeding.
We enjoy weeding, for the first couple of weeks of spring. But their persistence gets to us after a while and we begin looking for short cuts. How can we control weeds with as little commitment to time and effort as possible?
Fortunately, our years of gardening experience have taught me a few things about this.
Here are our top weeding tips:
BE AN EARLY BIRD. The early bird does, indeed, get the weed. Knock a weed down while it is a baby and you have removed future work 10-fold. How is that? The root of a weed gives the top half of the weed life, vigor and speed. Cut a weed off with a sharpened hoe and you remove the ability of the plant to photosynthesize. This either starves the poor darling to death or, at the very least; it pushes the ability of the weed to re-grow backwards for a spell. The secret: Sharpen your hoe with a file each time that you use it. Spray it with a little oil to help it move effortlessly through the soil. And do it early in the season before the root gets too deep. Like now. Tip: for the most effortless weeding use a Mark’s Choice Back Hoe. Home Hardware.
MULCH. The miracle of bark mulch is that it is non-chemical, easy, fun to spread (it smells nice!) and it can eliminate up to 90 per cent of weeds before they become established. The secret is to use at least six cm of shredded cedar or pine bark mulch to prevent most annual weeds from popping through the soil in the first place. The sooner you do this, the better.
BLACK PLASTIC. Place thick (at least six mil) black plastic over your lawn or garden and anchor it with something heavy. Wait for a minimum of six to eight weeks and you will kill just about everything under the plastic membrane. Other than some stubborn hard-to-kill weeds like horse tail or Phragmites (the new imported curse) you are good to go once you have cooked the weeds beneath the plastic. While the process takes time, it is thorough, and no chemicals are involved. This process works best in bright sun.
Weed control does not have to be onerous. In fact, we find some recreation in the activity of hoeing weeds down in the garden and pulling them from the lawn.
The most frequently asked question we hear is, “How do I kill lawn weeds?” And the answer is simple: Compete them out of existence. Here is our fourstep recipe for a thicker, greener and (for the most part) weed-free lawn.
- Rake the area of thin or tired grass gently using a leaf rake, removing all loose debris and getting grass blades to stand up on end.
- Spread lawn soil (or triple mix) about three to five cm thick and rake this smooth.
- Hand-broadcast quality grass seed on the area.
- Rake this smooth, step on it to bring the seed in firm contact with the soil and water until germination occurs. Keep it damp during hot, dry spells and fertilize with quality, iron-based lawn fertilizer containing slow release nitrogen.
