Weeding, like watering, is something that needs to be done regularly. Weeds can rob your plants of the nutrients and water they need. If the weeds get too big, they can shade plants that need sun and make your garden look messy.
Weeds--like flowers--are either annuals or perennials. Annual weeds such as crabgrass, purslane, foxtail and pigweed complete their lifecycle in one year. The best way to control an annual weed is to eliminate it when it first pops up. Be careful when pulling weeds that have grown larger. You run the risk of uprooting plants or damaging root systems next to it.
Perennial weeds have stronger root systems than annuals. They are tougher to get rid of, and they come back every year. Dandelion, thistles, ground ivy and quack grass are all perennials. You really have to keep on top of these weeds. Regular cultivation keeps them from becoming deeply established.
The most critical time to weed is during the first few weeks after transplanting or seeding. You want your plants to get a good start before the weeds creep in to compete for moisture and sustenance. Always try to pull out any weeds by hand. Do this after watering, when the soil is moist, to make the weeds easier to remove. If you can, avoid the use of herbicides by getting rid of weeds when they are small.
For persistent weeds or large areas, you can use an herbicide:
- Pre-emergence herbicides need to be applied before the weeds sprout up. This is best to use on lawns to get rid of crabgrass and dandelions.
- Post-emergence herbicides are applied after the weed has sprouted. These are not always best for gardens because what kills the weeds can also damage plants you want to keep. Use it sparingly.
- Spot-treat weeds using a sponge or cloth attached to a stick. Dip the sponge into the herbicide and wipe it on the leaves of the weeds. Avoid getting it on the plants you want to keep. Protect your hands with waterproof gloves.
