After planting poplar trees and watering them, the weather will get cold, minus 5 degrees. Will it freeze to death?

Poplar seedlings watered at MINUS 5 degrees are afraid of freezing, but they will not die. Fertilization can also be done in the greenhouse. According to the relevant analysis report of poplar growth nutrients, poplar growth mainly needs nitrogen, phosphorus, potassium and calcium. In the specific process of poplar planting, it is necessary to accurately grasp the types of nutrients added in poplar planting and fully ensure that sufficient nutrition supply can be obtained in poplar planting. The development of various flight tests should also be combined with specific conditions, and the time and methods should be reasonably controlled.

Poplar fertilization should try to avoid the rainy season to avoid being washed away by rain. Usually, all kinds of fertilization work are carried out in the early stage of poplar transplanting, and water-soluble fertilizers can be used to ensure sufficient nutrients in the soil.
