If you want to have a rich harvest of apples, you should now in April give your apple trees this nourishment! Fertilizing apple trees is important and you should do it twice a year, in spring and in autumn. Usually apple trees bear fruit every other year, because after a heavy crop the apple tree is exhausted and needs to take on new nutrients. With the right fertilization you can change this and it will be ready to start fruiting again even earlier.
It is important to know that nitrogen stimulates the growth of leaves and shoots , but if a tree has too much nitrogen, this will favor the growth of green parts and it may happen that the trees will not bloom and will instead be more susceptible to disease. Phosphorus, on the other hand, supports the flowering of trees, fruiting and strengthens the roots.
May fertilization
In April each fruiting tree should be fertilized with 30 g of urea, 40 g of brine and a bucket of humus. You can also choose liquid fertilization: for 10 l of water add 100 g of superphosphate and 60 g of potassium sulfate. Add half a liter of fermented poultry manure to that. In the case of young trees you should consider the use of fresh manure with caution, because you could burn the roots. When using fresh manure it is advisable in spring to use more quickly decomposing manures such as horse manure or fermented and thoroughly diluted poultry droppings, sheep manure, pig manure, or adding compost or peat is also a suitable solution.
Pruning apple trees
For apple trees the most important timing is at the end of winter, before the trees begin to bud. A supplementary time for pruning pome fruits is the summer prune, which should be carried out during the growing season.
