Self-made orchid foliar fertilizer

Homemade nitrogen fertilizer: prepare some vegetable leaves, peanuts or expired milk powder, grind them into powder, put them in a transparent container, put them in a bright position, seal and ferment, and dilute them. Self-made phosphate fertilizer: put fish bones, pig bones, egg skins and other substances into containers, add some water and starter, and dilute them after fermentation. Self-made potash fertilizer: dilute the tea water after fermentation.

Foliar fertilizer application doubles the effect of adding 1 material.

If you want to improve the effect of orchid foliar fertilizer, you can add this material-urea when making foliar fertilizer solution. Urea has a softening effect on the cuticle of plant leaf epidermis, and does not affect the original nutrients and concentration of fertilizer solution. When spraying foliar fertilizer to the orchid, after diluting the liquid fertilizer, adding a certain proportion of urea can make the orchid absorb nutrients faster and better.

After applying foliar fertilizer to orchids, it is necessary to let the fertilizer stay on the leaves for a period of time in order to make the orchids more fully absorb nutrients. Therefore, it is generally best to apply foliar fertilizer to orchids in cloudy days when there is no wind, or in the early morning and evening when the air humidity is high and the flow speed is slow.

When spraying foliar fertilizer to orchids, it is best to use a spray can, and the liquid sprayed is best in a fog. The fine water fog is easier to enter the leaf epidermis, and it is not easy to cause stagnant water in the center of the leaf. When spraying, it is best to spray upward from the back of the leaf, on the one hand, it can reduce stagnant water in the heart of the leaf, and the absorption efficiency of the back of the orchid leaf is higher than that of the front, so that the orchid leaf can absorb more nutrients.
