It would be ideal if you sprayed the crown of fruit trees in the garden of a concentrated solution of urea (about half a liter to 10 liters of water). We recommend to you all the soil, which is located around the trunk of the tree to pour a solution of 700 grams of urea per 10 liters of water. It is better to spray the trees in early spring and after flowering. For this we use the treatment (2 ampoules swift to 10 liters of water). When you finished the second spraying, feed the tree,you have to dissolve in a small 10 – liter bucket of water no more than 50 grams of urea and potassium salt. We recommend to you repeat the process of fertilization after 20 days.
