How to prune Aster novi-belgii? Detailed guide to the correct pruning method

1. Is it tolerant of pruning?

For this plant, it is extremely tolerant of pruning. This is because it has relatively many branches. So being tolerant of pruning naturally becomes another of its characteristics. Therefore, when pruning, just go ahead and prune boldly; there is no need to worry that its growth will be affected.

2. How many times a year to prune

In a year, it can be pruned five times. However, the timing cannot be chosen at random. It is best to prune it at specific times. During the growing season, prune four times. There is one more time, during its full-bloom period.

3. Specific times

(1) The first pruning is best done around June 10.

(2) The second can be around July 5.

(3) The third can be in late July.

(4) The fourth can be chosen for late August.

(5) The last pruning is during the National Day holiday. This one is relatively important. This is because, although its flowering period is relatively long, the overall ornamental effect is not particularly good. Only through pruning can its flowers be made to bloom in a concentrated period, making it look better.

4. Specific methods

(1) For the first two prunings, you can prune heavily. That is, you can cut off all the tips. In this way, the axillary buds can sprout more, and there will be more branches.

(2) For the next two prunings, what we mainly consider is its appearance and shape. Prune according to the specific situation; do whatever looks good. After pruning, it is best to make it look relatively harmonious.

(3) For the last one, the main thing is to control the timing. Because its full-bloom period is very short, sometimes only about a week. So at this time you must seize the opportunity.
