Thoughtful gardeners who care about their plantings and expect to reap a rich harvest carry out a number of additional fertilizers.
It is no secret that an apple tree can please you with abundant fruiting. You just need to give it enough nutrition.
Root feeding
2-3 weeks before flowering, the apple tree is fertilized for the first time. Nitrogen fertilizer is added, which is necessary for trees in the spring. For example, urea or ammonium nitrate are used.
The amount of fertilizer depends on the age and size of the plant. On average, the dose is 30-50 g per 1 sq. m of the trunk circle.
Mineral fertilizers can be replaced with organic ones. For example, prepare a solution of bird droppings - dilute with water in a ratio of 1:20. Alternative options are liquid manure (1:10) and compost (3 buckets for an adult plant).
The second feeding is carried out in May. The “menu” consists of:
1. Superphosphate (30-50 g) and the same amount of nitroammophoska per 1 sq. m.
2. Azofoska (30-50 g) and wood ash (100-150 g).
One of the two options is ideal for apple trees in late spring.
The autumn “menu” for trees consists of phosphorus (superphosphate, phosphate rock) and potassium (potassium nitrate) fertilizers.
Foliar feeding
The advantages of such fertilizers are that they strengthen the immunity of plants and deliver nutrients to tree tissues faster.
In this case, gardeners have several options to choose from:
1. Urea – 2 tablespoons per 10 liters of water.
2. Wood ash. First, take 2 liters of hot water. Stir a glass of fertilizer into the liquid, and then bring the total volume to 10 liters.
3. Iodine – 10 ml per 10 l of water.
Foliar feeding is acceptable during fruit ripening. Frequency: once every 2-3 weeks. Stop foliar feeding 30 days before fruit ripening.
