Tips for Using Horticultural Sprays Different types of horticultural sprays can help you to preserve the beauty of your lawn, garden and trees. If you need to treat your landscape for weeds or pests, then keeping the following tips in mind might make the process easy and effective:
Tip # 1: Spray large swathes of lawn.
If you have a large plot of lawn with heavy weeds disbursed throughout, you will want to spray using a concentrated herbicide and a garden hose. This provides even distribution of weed killer across your lawn. Make sure you spray on a still day so that you do not introduce unnecessary quantities of herbicide into the environment.
Tip # 2: Spot kill sporadic weeds.
Small handful of weeds that are concentrated in specific areas can be spot killed with a hand held bottle of weed killer. Simply wet the offending weed when the weather is fairly cool, approximately between 60 and 80 degrees, as hotter temperatures can evaporate the herbicide.
Tip # 3: When in doubt, pull rather than spray.
If you are unsure about using herbicides in your garden because you don't want to risk harming your garden plants, just pull the weeds at the root.
Tip # 4: Go for organic alternatives for your fruit and vegetable garden.
Vinegar and citrus oil based organic weed killers can be used in gardens that feature edibles that you don't want to risk contaminating. These are effective, but might alter the pH levels in your garden soil. Make sure that you test your soil before and after you use organic herbicides to make sure that the soil's balance hasn't been disturbed.
Tip # 5: Make sure you do not cross contaminate pesticides and herbicides.
Using the same bottles to spray your pesticides and herbicides might harm your plants if you do not thoroughly clean them between uses. Using a bottle to spray your pesticide that has previously contained herbicides will kill the plants you are trying to protect.
