How to Make Homemade Weed Killer?

A weed is an unwanted plant that can grow in any human controlled or natural plantation. Weeds obscure the nutrients, sunlight, and space for the desired plants and thus inhibit the growth of the plant and reduce its production yield. Weeds can grow by the spread of seeds by winds, waterways, animals, birds and human activities such as machinery.

How to Control Weeds?

There are various ways to control the growth of weeds. Some people suggest that pulling the weed plants up is the best method to go about weed control, but that is a fallacy because when the weed plant is pulled from the soil, some part of it, either the roots or the seeds get left out in the soil and the weeds can sprout again from them. The other most popular and the effective method is the use of medicines and weed killers. Such weed killers are readily available in the market and they can also be easily made at home thus saving the user a considerate amount of money.

The best time and frequency of application of homemade weed killer

Before you target the weeds with vinegar, study about them a bit, get to know them. Make sure that you target annual seeds before they set seed. For perennial seeds, which are difficult to handle, take off their followers when you see them and then apply vinegar on them. Check the weather forecast for your region, make sure that you choose a sunny and dry day to apply the weed killer on weeds as if it rains the weed killer will float on to the soil and it will be harmful to the soil and other plants as well. Make sure that this dry stretch continues for at least three days. Because the real damage to weeds will only occur when the sun hits the weeds for next couple of days. Depending upon the type and amount of weeds, apply the weed killer until you get the desired result but keep the soil safe from repeated application.
