FAQs
Are liquid fertilizer harmful to kids or pets?
It is safe to use the liquid fertilizer on the lawn, but allow from 24 to 48 hours before kids, pets, and pregnant women walk on your property. Make sure that they will stay off the lawn after you’ve applied the synthetic fertilizer until it gets completely dry after a good watering.
Should you water after liquid fertilizer is applied?
Make sure to deeply water the soil several days before applying liquid fertilizer. And, right after applying, immediately water to get rid off any fertilizer granules.
How often and how much should I apply fertilizer?
The side of your fertilizer bottle will tell you how often you should use the fertilizer as well as the rate of fertilizer each time you apply it to your lawn.
For example, during the growing season, you should apply water-soluble fertilizers every ten to fourteen days. Meanwhile, granular fertilizers require application about every 6 to 8 weeks.
Is it possible to add excess fertilizer?
As fertilizer has high percentage of salts that can easily dry out the plant tissue, over-fertilization can lead to a high salt concentration which can alter the soil, hurt beneficial microbial species, and damage roots. Excess fertilizer is likely to increase the chance of your plants growing suddenly with an inadequate root system to supply your greens with a sufficient amount of water and nutrients.
Also note that too much fertilizer added can be leached into the groundwater, thus being bad for our environment.
When to apply liquid lawn fertilizer?
The best time to apply the liquid fertilizer should depend on the type of fertilizer you will be using. Usually, you can follow some general guidelines or detailed instructions printed on the label of the fertilizer.
Gardeners should apply liquid fertilizers right after mowing the first grass flush from the soil. In July and August, avoid applying organic fertilizer at the plants and soil.
