How to cultivate potted rose trees as winter approaches
Rose flowers are known as the queens of flowers and the monthly reds, as they bloom throughout the four seasons with a rich fragrance and unique shapes, making them deeply loved by many. Roses are widely used in parks and green belts, not only for their high ornamental value but also for their special medicinal value. Many cities have named roses as their city flowers, which shows the popularity of roses.
With the arrival of winter, many flower enthusiasts have consulted our potted rose tree factory, wanting to learn how to cultivate roses during this season. Let's take a look together with the potted rose tree factory!
1. Prepare soil for repotting and ground planting. Roses prefer slightly acidic to neutral sandy loam soil. Generally, the cultivation soil should be sourced locally. You can mix five parts garden soil, three parts coal slag, and two parts mature sawdust, cottonseed hulls, moss, and草坪 clippings, then disinfect and set aside for use.
2. In the late November, give the roses a comprehensive pruning and shaping. Since different varieties have different cultivation requirements, pruning should not be uniform. Only light pruning and removal of unnecessary branches are recommended. Of course, all dead branches, weak branches, crossing branches, disease and pest branches, and the original rootstock below the grafting point must be cut off. For potted rose trees and tree-like roses with special shapes, the pruning should be combined with the above principles and handled according to specific conditions.
3. After the beginning of winter, stop applying organic fertilizers, especially those high in nitrogen; immediately top the suckering branches and grafting seedlings; do not剪 off the autumn残花 prematurely to avoid the growth of tender new branches at the top. Such treatment can promote the lignification of the branches and prevent damage to the roses from frost and cold waves.
4. January to February is a good period for ground planting and repotting roses. In the north, it can be postponed appropriately. Choose a sunny day, dig up the ground plants (usually once every three years), and for potted roses, remove the plant from the pot with bare roots. Carefully inspect the root condition of the rose, keeping the roots of ground roses as much as possible; for potted roses, trim the roots appropriately based on the plant size and pot diameter. Over-pruning the roots can slow down the plant's recovery in the spring and affect the flowering. After the above treatment, whether for ground planting or potting, you can replant after applying a nitrogen-rich base fertilizer,浇足 anti-freezing water, and take appropriate measures to prevent the early spring cold wave.
5. During the winter dormancy period of potted rose trees, conduct a comprehensive clean-up of the garden in early December and before repotting, gather all dead and residual branches and leaves and burn them. Use a Bordeaux mixture with a concentration of 3 to 5 degrees of lime sulfur or an alternating spray of 800 times of dichlorvos or similar pesticides to kill insects and sterilize.
6. Apart from浇足 a potassium-rich fertilizer ten days before the beginning of winter, no fertilization is needed during the entire overwintering period. Watering should be based on the plant's placement environment and weather conditions, following the principle of not watering when not dry. Prevent waterlogging; if it's sunny for five to seven days, water thoroughly at noon.
