Provide nutrients after transplanting. Until new roots are formed, the plant is completely dependent upon stored nutrients to maintain itself, but foliar feeding can minimize the shock and keep the plant growing.
Cold soil in early spring growth can be limit perennials, even when the air is warm. Soil microorganisms are not capable of converting nutrients into forms available for roots to absorb. Foliar feeding can quickly provide the needed nutrients to the plants, thus allowing the plant to begin growth before roots can furnish needed nutrients from the soil.
Provide peak need feeding when the plant can demand nutrients faster than the roots can furnish them. Foliar feeding can influence flowering, fruit set, fruit size, amount of vegetative growth, among other things.
Allows flexibility in supplying nutrients. Small imbalances in the soil can lock up various nutrients, foliar feeding allows the ability to correct these problems. Iron is in most soils but is very hard to get into a form plants can use.
Can provide nutrients during times of plant stress. It can protect plants from the damage of weather extremes and drought.
Help provide disease and insect protection.
A supplement, not a substitute – Remember that foliar is very useful, but cannot replace healthy soil and roots. A plant’s roots purpose is to supply large amounts of nutrients which you cannot get through foliar feeding.
