Planting walnut seedlings before and after the fall of leaves is the best, that is, in the solar calendar in October-November. At this time, the walnut seedlings have been capped not pumping new tops, basically into a dormant state, after transplanting at this time, before freezing, walnut seedlings are sprouting new roots, the next year's growth is very favorable. The crown of the year can reach 4 square meters.

Planted before the freeze, this time the walnut seedlings have entered a completely dormant state, transplanting process, saplings like in the "dream", transplanted, spring warming saplings directly sprouting roots, to avoid damage, the survival rate is also very high, the year's crown is generally in 2-3 square meters.

Spring planting, the saplings at this time, whether in the nursery not out of the nursery, or false planting, the root system has begun to sprout, transplanting process, the root system will be damaged, slow seedling, survival rate is low, the crown of the year in 2 square meters or less.

Planted in late spring, when the saplings have been rooted in the soil, transplanting process sapling damage is serious, slow seedling slow survival rate of less than 50%, the year basically no crown.

Summer planting, this time the saplings have sprouted new branches, water demand is greater, transplanting due to sudden water cuts, almost difficult to survive.

So people often say, "fall (end) winter tree planting a dream, spring tree planting a disease, summer tree planting to be it life.
