This is the software of food to the airy parts of plants . It can be used for the treatment of all want for all type of acquire plants . But you could only spray very small amounts of food onto the leaves at a time , otherwise , leaf singe or even defoliation may follow . If foliar spray is to be successful there must be sufficient foliage to hold the applied food , and industrial plant can not rise to a degree of increase when foliar intervention , would be good unless the dirt has been prepared in good order before sowing or planting . So , although foliar eating can not take the position of the traditional method acting of apply fertilizers and manure to the dirt , it is a useful supplementation , for the following purpose :
Foliar applications of potassium nitrate to roses have often produce more richly tinge blooms and dark green glossy leafage .
Methods of application
nutrient can be applied as dusts or spray . delicately ground fertilizers may be dusted onto damp foliage but these are not as efficient as sprays because more of the fertilizer falls off the leaves and about twice as much fertilizer isrequiredto give as good an effect as a nebuliser .
So it is best to habituate spray , especially when applying trace component fertilizers , which are required in very small amount of money . The fertilizers listed in the tabular array below are applied at the pace suggested , using an ordinary garden sprayer or a watering can with a fine rose .
Time of application
If deficiency symptoms have occurred at an former stage spray should be done immediately there is enough leaf to spray , followed by a further program in 2 - 3 calendar week since most of the first program will have fallen on bare ground .
Where a deficiency occurs every year it is best to implement the foliar spray before symptom come out .
Special hints
Always spray both upper and lower surfaces of the leafage , because immersion is greater through the under surfaces of the leaves .
habituate a fine mist atomizer and add a folio wetting agentive role ( not a Georgia home boy type ) to the spray . This will serve to bring down the danger of leaf scorch . Spray in later good afternoon or on a dull solar day , since best solution come applications made under slow drying conditions .
Do n’t spray if the weather is blistering and sunny , or scorching will be severe . Avoid showery weather , or most of the food will be washed off .
Always get an expert to name a deficiency before you begin handling .
