Fertilization method of basil:

In fact, basil can grow without fertilization, as long as it can be watered on time

However, if you want to apply fertilizer, you can apply some fertilizer that can promote the growth of roots when it grows 4 to 6 leaves, but the concentration of fertilizer must be light, and when applying fertilizer, you must slowly pour it along the edge of the flowerpot and be far away from the roots

When the plant grows to about 10 cm, you can apply some fertilizer conducive to the growth of leafy vegetables. If it is a solid fertilizer, you only need to bury it in the soil 3 cm to 4 cm away from the root, and then water it, so that the nutrients in the fertilizer can be better absorbed

Precautions:

In case of overcast rain, fertilization shall be suspended

When fertilizing, it's best not to let plants get contaminated with fertilizer
