How To Apply Fertilizer

However , some consider it to be the most wasteful , especially in sandy stain where it can well be washed down out of reaching of the plants .
Unless the stain is well mixed , it is often just dumped to the bottom by the plowing or spading and the immature plant must do without it in their former stages .
A good method is to spread out the proper amount over the soil after it is turn over and just before a thorough raking . This gets it well mixed in the upper few inch and allows it to wreak its way down .

The enriched solution is then fed to roots of trees , shrubs , rose , etc . through a hollow spike - like applicator that is pressed down into the soil to the proper astuteness .
Another in force form is the use of “ fertiliser spike ” in which fertilizer manufactured into a tablet or spike and is placed in the ground and slowly dissolved by moisture and lacrimation as it comes in contact with the spindle .
Foliar Fertilizer Feeding Through The Leaf
Lastly , we have foliar , or through - the - folio , feed . Only completely soluble materials may be used and care must be direct to keep abreast the maker ’s directions explicitly .
Once the correct amount has been calculated for the apparatus at script , the liquidfertilizer concentratemay be applied with a formal sprayer or a hosepipe atomizer , either at the time of spraying or severally .
