Planting method of tree seedlings
Tree seedlings are divided into seedlings, grafted seedlings, transplanted seedlings and so on, and different species have different growth habits. The propagation of tree seedlings: it can be propagated by grafting, cutting seedlings and root seedlings. The planting method of tree seedlings: first of all, dig the planting pit and set aside the appropriate growth space, which is generally about 30 centimeters.
