What Causes the branches of roses to wrinkle
Today's focus is to introduce you to the related content about why the branches of roses wrinkle in the aspect of green plants. Next, the site editor will introduce the topic to netizens.
Can the wrinkled branches of roses be saved? To save them, you need to first understand why the branches of roses wrinkle. Here are 6 common reasons summarized, hoping they are helpful to you.
1. - Excessive watering causes the roots of roses to become soggy -
Whether it's roses in pots or roses planted in the ground, if the soil is waterlogged for a long time, it can lead to the rotting of the rose roots, losing their absorption ability. This manifests in the branches as blackening and wrinkling of the epidermis. If not discovered in time, it can cause the whole plant to wither.
In the daily management of potted roses, watering should be done when the soil is completely dry, and no watering should be done when the potting soil is not dry. When there is a lot of rain outdoors, it is important to drain the pots to avoid waterlogging. For roses planted in the ground, they should be planted in slightly higher positions, not in low-lying areas, as they can easily accumulate water and rot the roots.
2. - Excessive drought -
Roses are not very drought-resistant. If potted roses are not watered for a long time and the potting soil is excessively dry, the rose roots cannot absorb water, leading to dry and wrinkled branches.
In cases of drought-caused wrinkling of rose branches, water should be补充ed by immersion immediately. Usually, after immersion, the wrinkles on the rose branches gradually disappear and return to fullness. Of course, excessive drought will definitely affect the normal growth of roses and should be avoided. Especially in summer, watering should be timely.
3. - Severe fertilizer damage -
Roses love fertilizer and need to be fertilized regularly during maintenance. However, if the concentration of the fertilizer is too high, it can easily cause fertilizer damage. When severe fertilizer damage occurs, the rose roots are damaged, which can lead to insufficient water absorption and result in the wrinkling of the branch epidermis.
When fertilizing, it is recommended to refer to the instructions and dilute the fertilizer to the recommended concentration before use to avoid severe fertilizer damage.
4. - Borers have bored into the main stem or root -
Large, mature rose plants with thick main stems are easily targeted by borers. Borers lay eggs on the branches of roses, and after hatching, the borer larvae bore into the main stem. As the main stem of the rose is hollowed out, the branches may show yellowing, reduced vitality, and suddenly one day, the skin of the rose branches may appear wrinkled and dehydrated. The damage caused by borer larvae is slow and can easily be overlooked.
What Causes the branches of roses to wrinkle
If roses are infested with borer larvae, sawdust-like excrement can often be seen near the root surface. Once borer larvae are detected, they should be treated promptly. You can use a sticky ball soaked with insecticide and insert it into the bored hole to eliminate the borer larvae.
Generally, branches with minor boring damage can still grow and bloom, but severely damaged branches should be cut off.
In addition to borer larvae, the larvae of the chafer beetle are also a significant threat. The symptoms of rose roots being bored by chafer beetle larvae are similar to those of borer larvae.
If you suspect that roses have been infested with chafer beetle larvae, you can bury phoxim granules around the rose roots. For severely infested rose plants, it is recommended to apply root-promoting agents to the branches near the soil, cover them with soil, and allow the branches to grow new roots. Generally, after insect control and root promotion operations, the rose seedlings can be saved.
5. - No pruning was done when large plants were transplanted -
Especially for larger ground-planted climbing roses, if the branches are not pruned during transplantation and long branches of 1-2 meters are retained, the severe damage to the rose roots cannot support the consumption of so many long branches, leading to the wrinkling and dehydration of the epidermis of the branches.
If you encounter this situation, Green Enthusiast Network suggests that you prune the branches promptly, retaining only 30-50 cm in height, which makes it easier for the transplanted roses to survive.
6. - The wind has dried out the moisture in the branches -
Especially the tender branches of roses can easily be dried out by moisture during windy and cold weather, leading to the dehydration and wrinkling of rose branches.
Even semi-lignified branches can easily lose water in cold winter if the wind is strong, so it is recommended to take good wind protection measures.
