Spraying fertilizer onto plant leafage , also make out as foliar industrial plant nebuliser or foliar feeding , is a technique in gardening and landscape gardening where fertilizers are give like a shot to the leaves of industrial plant alternatively of being placed in the soil . This method allows the plant to absorb nutrient more quick and expeditiously , like to how humans might place an aspirin under their clapper for immobile absorption into the blood stream .

Foliar eating is a valuable shaft in flora care because it provides an quick nutrient boost to industrial plant , especially in situations where the territory may be deficient in sealed food or when works are know nutrient deficiency . By spray fertiliser instantly onto the leaves , the nutrients short-circuit the soil and are take in through the stomata , which are modest opening on the leaf surface that facilitate gas exchange .

One of the fundamental advantages of foliar eating is its power to rapidly correct nutrient deficiencies . When plants lack sure nutrient , their growth and overall wellness can be compromised . By applying a foliar atomiser containing the necessary nutrient , plants can quickly absorb and utilize those nutrient to address lack and resume healthy growth .

moreover , foliar alimentation can be peculiarly good in spot where the soil pH or nutrient handiness may bound the uptake of certain nutrients by the roots . Some nutrient , such as iron , may become less usable to works in alkaline soils . In such typesetter’s case , foliar sprays can leave a lineal provision of Fe to the folio , bypassing the grunge limitation and supporting industrial plant health .

Another reward of foliar spraying is that it can be used to supplement soil - base fertilization . Even if plant are already receiving nutrient through the soil , foliar feeding can provide an additional encouragement during critical growth stages or fourth dimension of strain . For illustration , during period of drouth or utmost heat , plants may struggle to take up nutrients from the stain due to reduced stem action . Foliar spray can help provide the necessary nutrients to support growth and derogate the effects of stress .

When using foliar spraying , it is authoritative to consider the type of fertiliser being applied . Liquid fertilizers are commonly used for foliar feeding because they can be well sprayed and take up by the leaves . These fertilizers are typically water - soluble and control a balanced mix of indispensable nutrients , such as N , daystar , and potassium , as well as micronutrient like iron , atomic number 25 , and Zn .

It is essential to follow the manufacturer ’s instructions and dilute the fertilizer befittingly , as overweening engrossment can damage the leaves . Additionally , spraying should be done during cool parts of the day , such as early dayspring or even , to minimize the endangerment of leaf suntan triggered by the sun .

In my personal experience as a gardening enthusiast , I have found foliar feeding to be effective in providing quick relief to industrial plant stick out from nutrient deficiencies . I have witness improved increment and greener foliage after applying foliar sprays containing balanced nutrient formulations . However , it is important to mark that foliar feeding should not replace regular soil - based fertilization , as plants still require a nourishing - robust soil for long - full term health and vitality .

To summarise , foliar spray is a technique in which fertilizer are applied directly to imbed leafage , allowing for warm absorption of nutrients . It can be used to address nutrient deficiency , supplement soil - ground fertilization , and surmount limitations in nutrient ingestion have by soil pH or handiness . However , it should be used as a completing practice alongside regular dirt fertilization .
