When is the best time to apply fertilizer to plants?

The best time to apply fertilizer to plants is during their active growing months. This is because plants require more nutrients when they are in their growth phase, which typically occurs in spring and summer for many species. During this time, the plants are photosynthesizing more actively and are better able to utilize the fertlizer, promoting healthy growth, blooming, and overall vitality.

Applying fertilizer during periods of dormancy, such as in the winter months, is generally ineffective as the plants' metabolic processes slow down significantly. They are not actively growing, so the nutrients from the fertilizer are not used efficiently. Similarly, fertilizing every few months or only when plants show signs of wilting can lead to improper nutrient management, potentially harming the plants or leading to nutrient imbalances. Thus, targeting fertilizer applications to coincide with periods of active growth ensures that plants receive the maximum benefit when they need it most.
