Is it better to spray nutrient solution on leaves or water the soil (with usage methods for common plants)

1. Is it better to spray leaves or water the soil?

Spraying the leaves with nutrient solution is relatively better than watering with soil. This is because the purpose of the nutrient solution itself is to help the leaves grow more vigorous and green. Therefore, spraying the nutrient solution directly on the leaves will help the leaves absorb nutrients more directly and quickly. The method of watering the soil with nutrient solution is more indirect, and it takes longer for the leaves to receive nutrients. Since the concentration of the nutrient solution is relatively high, you should not use too much to avoid root burns or leaf scorches. The remaining nutrient solution after spraying the leaves can be used to water the roots of the plants, making the best use of it.

2. How to use some common plants

1. One of the most common plants we see is the green ivy, which is a foliage plant. You can spray the diluted nutrient solution directly on the back of the leaves or branches, so that the leaves can absorb the nutrient solution better and make the leaves brighter.

2. The leaves of lucky bamboo can also be used for spraying. You can drop a few drops of it into a spray bottle and mix it with water and then spray the leaves. However, if you are doing hydroponics, it is better to drip it directly into the water for maintenance.
