How to prune a tree-like rose
Introduction: This article covers knowledge about pruning tree-like roses and the illustrated pruning methods for these green plants. Next, let's dive into the introduction by the editor.
Key points: So-called tree roses are almost all grafted roses, with the rootstocks usually being roses or mountain mock oranges. Roses are generally grafted to create棒棒糖-style roses or old-stump盆景, while large tree roses usually use mountain mock oranges for grafting. Tree roses are very popular and can have several colors of roses grafted onto a single tree, resulting in a colorful display after blooming. They are widely used in urban绿化 and are also a great choice for potted plants. Adding a couple to a courtyard can be quite stunning.
How to prune tree roses? The pruning of tree roses mainly follows the shape characteristics of 3 trunks with 6 branches or 6 trunks with 12 branches, forming a pagoda shape that is very attractive.
1. Remove suckers
After successful grafting, the main task of maintenance is to remove all new shoots from the rootstock and any suckers emerging from the roots. We want the grafted roses, not the rootstock branches, so removing these suckers allows nutrients to concentrate on the grafted roses. This task of removing suckers is ongoing and cannot be neglected; otherwise, it can lead to the waste of nutrients by the rootstock and premature aging of the grafted branches.
2. Cultivate main trunks and grafted branches
As mentioned earlier, the main pruning method is to create shapes with 3 trunks and 6 branches or 6 trunks and 12 branches. Of course, there are other shaping techniques as well. We graft branches according to the size of the rootstock and space them out. If any grafts do not survive, they should be promptly replaced. After the grafts survive, the main trunks should be well maintained.
When the new branches of the grafted roses grow to about 4 centimeters, they should be cut back to achieve the goal of 3 becoming 6, and 6 becoming 12, which simply means increasing the number of branches. When the secondary branches reach about 4 centimeters, they should be cut again. The focus is mainly on cultivating primary and secondary branches to thicken them, while the tertiary branches are responsible for flowering. Do not cultivate tertiary main branches because too many branches may lack nutrients, making it difficult to bloom or resulting in very small flowers, which can severely lead to stunted growth.

3. Maintenance pruning
In our greening efforts, we mainly use a shape with 6 trunks and 12 branches, which is related to the size of the rootstock. Mainly maintain the primary and secondary branches, and prune them regularly. Do not let the branches be too dense, prune to create spaces, ensuring adequate sunlight and growth space for the branches. Tertiary branches are flowering branches, and they should be pruned immediately after flowering to encourage the growth of new branches for more flowers. As the primary and secondary branches become thicker with maintenance, they can be thinned out as needed to ensure good flowering quality and continuous nutrient supply.
Finally, in addition to pruning and shaping, the maintenance of tree roses is very important. It is necessary to regularly supplement nutrients and water, and ensure sufficient sunlight. The main goal is to keep the rootstock's roots vigorous. If the rootstock is healthy, it will continuously provide nutrients and water, ensuring the healthy growth of the roses. The rose branches should be pruned frequently to prevent and control pests and diseases, strengthen the tree's vitality, achieve perfect shaping, and result in an explosion of flowering branches.
The comprehensive explanation of how to prune tree-like roses and the illustrated pruning methods for tree-like roses mentioned above is hoped to be a starting point to help solve your problems with green plants.
