Is the thicker the high-pressure shoots of lemon trees, the better?

Planting depth is the key to survival, growth and development in the future, and even the key to winter. The roots of high-pressure seedlings are on the soil ball. If the soil layer is not covered with soil balls for 3-5 cm, the roots are easily dehydrated by dry air, and the fibrous roots growing from the roots are basically ineffective, so even if they are not dead, the absorption will be discounted. When plants germinate, absorption is definitely greater than evaporation, so it is not easy to form stiff seedlings when the depth is not enough, that is, absorption and evaporation are always in a state of balance. Moreover, in winter, once frozen soil is formed below zero, the roots will definitely freeze, but if the soil is deeper, the soil is lower and the temperature is higher, at least the roots will not freeze. Don't underestimate this 3-5 cm, this is the key. Don't be a realistic version of pulling out the seedlings to encourage them.
