Winter pruning is mainly plastic surgery. When the temperature drops below 5℃, cut off the dead branches, pests and diseases, overlapping twigs and immature branches sprouting after autumn from the main branches, and then prune them in three ways: strong, medium and weak.

1, strong shearing and weak shearing are suitable for plants that are not strong enough. About 2/3 of the whole plant is cut off, leaving 2-4 main branches for concentrated nutrition. In this way, the flowers in the coming year will be rich, which can fully reflect the characteristics of varieties. Strong pruning is the main way of potted large-flowered rose.

2. The moderate pruning is about 1/2, which is used for normal growth and the ongoing pruning of a uniform tree. Prune the diligent flower varieties suitable for easy-to-hair branches.

3. Weak Pruning The plants with vigorous growth and normal development are weakly pruned, and about 1/3 is cut off to prevent excessive consumption of nutrients. Flower roses and miniature roses can leave more branches as appropriate, which is more conducive to showing the characteristics of lush flowers.

After pruning, remove the residual leaves, clean the basin surface and pay attention to saving water. When the temperature drops to minus 5℃, it will be stored in a cold cellar or freezer. Knives and scissors for pruning should be sharp, so as to make the cutting mouth smooth and prevent the branches from splitting. Generally, it is cut 5 mm above the bud point, and the lateral bud point is generally left to make the branches stretch evenly, keep the plants ventilated and transparent, and prevent pests and diseases from lurking.

For branches with sparse branches, internal bud points can also be left as appropriate to make the plant shape properly folded and plump. If the roses planted on the ground overwinter in the open air and are cold-proof in late autumn, they should not be cut hard to prevent people from being hurt by air drying. After thawing next spring, trim it properly.
