Benefits of extra-root topdressing of flowers and plants

Extra-root topdressing is a fertilization method in which the diluent of chemical fertilizer or trace elements is sprayed on the leaf and absorbed by the plant through the leaf stomata, so it is also called foliar fertilization.

The advantages of extra-root topdressing are: small amount, rapid and significant fertilizer effect, fertilizer will not be fixed by soil, not affected by root absorption function, and so on.

Inorganic fertilizer is usually sprayed on the leaf surface, which can be absorbed 5 hours after spraying, and 50% Muth75% can be absorbed within 24 hours, and the fertilizer effect lasts 7-10 days, so it is appropriate to spray extra-root fertilizer once every 7-10 days.

Extra-root topdressing can be carried out at all times except the flowering stage, but it is usually carried out when flowers and trees are growing vigorously or lack of certain elements.
