Weeds are plants which tend to grow where you do not want them to grow. These are the plants that the gardener considers undesirable, but they still continue growing in the garden anyway and compete with your crops for nutrients and moisture. Controlling weeds can be really tricky, especially if you do not remove them as soon as they grow. Remember the bigger they become the harder it becomes to control them. So make sure you check for weeds in your garden at least once-a-week. Here are a few unique techniques you can use to control weeds.
A thick mulch layer can really help prevent light from reaching the leaves of the weeds, and without light, the weeds will not produce enough chlorophyll to help them grow. So they will sicken and die with time. The few weeds that will survive will be shallowly-rooted and quite easy to uproot. Organic mulches like shredded-bark, grass clippings and straw are actually a better option. This is because they tend to decompose and nourish the garden. Live mulches are also becoming famous among various gardeners. Setting up live mulches is quite simple, all you have to do is plant a fast-growing-short-plant to help cover the soil-surface around your garden.
If you are ready to leave the garden fallow for approximately 6 weeks during the summer, then you can allow the sun to help you destroy all the persistent weeds. You can start in the late spring or beginning of summer, by raking, or pulling weeds from your garden and then moisten it before burying the edges or covering it with plastic. Leave it for six weeks and by the time you uncover the garden, the sun will have already killed most of the weeds that will have germinated.
3. Apply corn gluten meal
You can apply corn-gluten meal over the region where the weeds tend to grow as pre-emergent weed-killer at the beginning of the season. This works perfectly for sprouting weeds and once this stage is passed, this meal becomes ineffective. And since it is not picky avoid applying this meal in regions where you have sown. Corn gluten meal works perfectly against crabgrass and dandelions among other weeds.
Weeds tend to die when their stems are detached from their roots right below the soil- level. So you can use a really sharp hoe to detach the weeds. The best tool for this job is a swan-neck or oscillating hoe and not the normal square-headed hoe.
5. Pour vinegar on the weeds
You can pour horticultural vinegar on the weeds to kill them. Remember the horticultural vinegar is 20% vinegar while the regular vinegar is 5% vinegar, so make sure you purchase the horticultural vinegar to help you with controlling weeds. This is actually one of the best weed controlling methods around because it works faster than the weeding chemicals. Vinegar tends to kill both the weed and its roots. Vinegar also works much faster during sunny days as compared to rainy or cloudy days. While pouring vinegar make sure you avoid pouring it on your plants.
