1. How to prune in spring

1. Cut off the remaining flowers: Generally speaking, the flowering period of bougainvillea is from November to the following year. It’s April, so it’s just the time when spring flowers are fading. When pruning, the remaining flowers should be cut off first, which can make the whole plant more beautiful, avoid unnecessary consumption of nutrients, and help subsequent growth. 2. Prune branches and leaves: After growing in winter, the branches and leaves are messy and can be pruned appropriately in spring. First remove useless branches from the plant, cut off dead branches, yellow leaves, and diseased leaves, cut off overgrown branches, and cut off some dense branches. This can stimulate the desire to grow and reduce nutrient consumption. Promote the growth of new branches and leaves, making the plant fuller. 3. Plastic pruning: In addition to cutting off useless branches, you should also consider plastic surgery to determine the desired plant shape and make the plant shape more beautiful through pruning.

2. How to judge whether the bougainvillea is dead

The bougainvillea can be used to judge whether it is dead. You can first look at the root cause. If most of the roots are rotten, black, or even dry, they are basically dead. If they are still healthy or have only a small amount of root rot, that is proof they are salvageable. Then look at the branches. If it's dry and wilted inside, it's basically dead. If it's still green and full of life inside, it means it's alive.
