Foliar spraying is a method of spraying nutrients directly on your plants’ foliage or leaves to feed them. A garden sprayer is used for foliar spraying.

The main advantage that foliar spraying has over soil feeding is quicker nutrient absorption. This method is beneficial when the plant develops a deficiency. In such a case, it is more helpful to spray the corrective nutrient on the plant to solve the issue as soon as possible. If you use the soil feeding method, it will take longer to solve the problem, and this can incur more damage to your plants. Nevertheless, remember that foliar feeding is not meant to substitute soil feeding; instead, it should be used supplementally in specific situations.

Foliar spray during flowering?

Foliar feeding is perfect for the veg phase and the first 1 or 2 weeks of the flowering phase. However, we recommend that you don’t continue with foliar feeding during the rest of the flowering phase because that could damage your buds and lead to an unsuccessful harvest.

What is the best time for foliar spray?

The ideal time for foliar feeding is when the lights are off. If you spray with the lights on, the nutrients can dry up too quickly. Also, the leaves and stem are in their most absorptive form right after turning the lights off.
