Fertilizer for fast-growing poplar

Fast-growing poplars grow faster if they are fertilized with nitrogen-based fertilizers. Nitrogen fertilizers are needed mainly during the growth period of fast-growing poplars. The best effect is achieved when nitrogen, phosphorus and potassium are applied together. No topdressing is required in the year of planting fast-growing poplars. Fertilization begins in June and July of the second year. The depth of fertilization can be about 5-10 cm. Then watering is performed. No topdressing is required after August.

Fertilization method for fast-growing poplar

If you are fertilizing during the seedling period, you can apply it in the form of liquid fertilizer. At this time, its root system is not very developed, so you can directly water it on the root system of the plant. The concentration and amount of fertilizer should not be too high to avoid root burn. When fertilizing after the fast-growing poplar reaches adulthood, you need to pay attention to keeping a certain distance from its root system, because as it grows, the distribution of the root system will become more and more extensive. If you fertilize too close to the base, root burn will occur.
