How to prevent lilac from growing taller

Root blocking method

If you want the upper part of the lilac to grow slower, you have to cut off part of the nutrient transport. This will affect the flowering of the plant in the early stages, but it will return to normal after shaping. Cut short part of the roots of the lilac and plant it in a flowerpot. The pot will limit the extension and absorption of the roots to a certain extent. In a relatively dry environment, the growth of the above-ground part will be inhibited.

Multiple short cut method

The shape of the tree can also be controlled by pruning and multiple short cuts. The plant can be trimmed into various shapes according to your preferences. Prune as long as the branches grow. Do not cut off the leaf buds when pruning. Under the condition that it does not affect the growth of the plant, control the plant height appropriately. Slowly the spider bar will form inertia and maintain a short and strong plant shape.

Coiling

The main method for shaping lilac into a short and sturdy shape is to use the coiling method, which uses brown rope or iron wire to coil and wrap the branches. For thick branches, bamboo and wooden sticks are also needed. After a period of time, a fixed posture will be formed. In addition, after being bundled into shape, it can be made into various shapes and used to embellish various objects, which is very ornamental.
