When to Prune Rose bushes Heavily
Today's sharing: A discussion on when to prune rose bushes heavily in the aspect of green plants and flowers, with detailed introduction below.
When to Prune Rose bushes Heavily
Rose bushes grow quickly, so they need to be pruned frequently. Rose pruning is divided into growth period pruning and pruning after the leaves fall in autumn and winter. Among them, growth period pruning focuses on light pruning, while autumn and winter pruning usually requires heavy pruning.
① Growth Period Pruning to Reduce Excessive Nutrient Consumption and Maintain Plant Shape
After the roses sprout in spring, with adequate water and fertilizer, they maintain vigorous vitality, sprouting many new branches that grow rapidly. If left unattended, this will affect the ventilation and light penetration of the rose bushes and lead to excessive nutrient consumption.
Therefore, pruning should be carried out during the growth period, mainly removing some weak branches, blind branches of roses that affect ventilation, and some diseased branches.
During the growth period, pruning has another task, which is to maintain the plant shape for better ornamental value.
② Pruning After Flowering
Roses are plants that bloom in multiple seasons. After each flowering, pruning is necessary. The purpose of pruning after flowering is to reduce the consumption of nutrients by the remaining flowers and, more importantly, to maintain the plant shape and consistency for the second bloom.
Pruning after rose flowering should not wait until all flowers have bloomed, but should be done after most of the flowers have faded, with unified pruning.
For a few unopened flower buds or flowers currently in bloom, they should all be cut to ensure that the next bloom is consistent, achieving a stunning effect of many flowers blooming at the same time.
③ Timing of Winter Pruning Should Be Grasped
Winter pruning is a very important task for roses, which can help the plants grow better the following year. However, it is not enough to prune randomly; the most important point is the selection of timing.
Winter pruning should not be done too early. Many friends start pruning after the leaves have fallen, but at this time, although the roses have lost their leaves, they have not entered a dormant state, and the nutrients have not yet withdrawn to the roots, leading to a waste of a lot of nutrients.
The correct time is to prune one week after the leaves have fallen.
Winter pruning usually involves heavy pruning, with weak and dense branches cut directly from the base, leaving 3-4 strong branches per plant. These branches should be shortened, with the remaining height of the branches around 15 centimeters.
