1. This is determined by the maintenance conditions, but relatively speaking, if it is to be planted in spring, it is busy growing new roots at this time, and it is also further differentiating flower buds, so it leads to insufficient nutrition in its roots.
2. There are two kinds of results. One is that it is relatively robust. It may bloom after planting at this time, but the flowers are not big and beautiful. The other is because it is very weak, coupled with the loss of root system excavation, making it less energy to bloom. If the maintenance is not good, I'm afraid that the later flowering will be affected, so the time for planting should be considered carefully.
Generally speaking, the best time is around September 23, which is the autumn equinox. At this time, the plants are resting, but their roots are still growing slowly. At this time, they are planted in the proper soil for good maintenance. After a fall and winter time, they can recover, so that they can be planted in spring. The damaged root should be repaired so that it can bloom again.
