How to top petunia

1. What is topping?

Many plants require topping. So, what does it mean? In fact, it is very simple. Just pinch off the top of the plant and remove the growth point of the stem. Doing so could eventually lead to an increase in production. It is also called "removing apical dominance". It is also necessary for this plant.

2. What is the best quantity?

It is also not difficult to top this plant. Just pinch off the leaves on the top. As for its quantity, generally speaking, the number of leaves left on the branch should be greater than two. At the base of each leaf, a branch may grow. Therefore, more than two leaves must be left. However, this is the general principle. As for how much to pinch, it depends on the specific shape of the plant. Different plants will inevitably have different shapes, so the amount of topping will also be different. In addition, there is another little trick, which is to decide according to the season. Generally, three or four leaves can be left in spring and summer. If it is autumn and winter, you can keep four or five pieces. However, this is not a definitive conclusion, and it is safest for readers to make their own decisions based on actual circumstances.

(1) The first is the density of nodes (the length of the branch between two leaves). If the branches are too long due to leggy growth, it is best to pinch them off.

(2) Then there is the density and position of this branch relative to other branches. In other words, the direction of the branches from which the leaves we leave behind must be consistent with the overall direction. This is not easy to grasp, but it will be fine after a few attempts.

(3) Topping can be done together with leaf thinning. If you see a part with very dense leaves, you can remove some of them.

(4) We need to follow a principle, which is to ensure that the entire plant is symmetrical.
