How to winterize roses in pots
The cold winter is getting closer. The temperature has gradually dropped in recent days. The rose is also the last flower. After they die, they must be properly preserved. Prepare your rose flowers for winter ahead of time. Leave roses in the cold winter and they won’t bloom the next year. Before the weather warms up next spring, the following 4 points must be completed.
Prune branches
In early autumn, rose blooms are slightly pruned. For the sake of autumn beauty, as autumn comes to an end, all excess branches, buds and all dead leaves must be pruned once so that their plants receive enough nutrients to successfully survive the cold. In winter, the next year will still be richer and the buds of new branches will continue to grow.
Strengthen fertilizer supplementation
After cutting flowers, when its flowers die, fertilizer must be added to make them nutritious enough, which is conducive to the arrival of the next flowering and the increase in quantity. Ternary compound fertilizer can be supplemented. Phosphorus and potassium are sufficient for the rose flower to be absorbed in all aspects. You can also put some animal manure or homemade fertilizer water in the soil. As long as the supplement is not too rich, the roots of the rose flowers will receive sufficient nutrients without any hindrance.
Reduce water gradually
The temperature drops day by day and the water slowly disperses. At this time, a large amount of water is not needed, the water gradually decreases, and the soil becomes dry. As long as the absorption needs of the plant can be met, it can be replenished twice a month in winter. As long as the soil is not very wet and the temperature does not cause frostbite to the roots, rose flowers are fine. If you survive the winter, this is not a problem.
Warming measures must be taken
Whether roses are grown outdoors or indoors, they must be preheated in advance and their roots must not be frostbitten. This will make it difficult for flowering to continue next year. In open-air care, branches can be pruned after flowering, only 10 cm above the roots. Wrap in plastic wrap, cover with straw mats, plastic sheeting, and compact with soil. Don’t leave it blank. Snow does not frost its plants. This method is eye-catching and makes it virtually impossible to transplant the entire plant indoors. If it can be moved closer to indoors, it is better to move it indoors for better insulation measures.
Roses can be kept warm in a warm room to absorb enough sunlight. They can also be covered with plastic bags to absorb more photosynthesis and cause them to bloom earlier, thereby increasing the number of flowers. It’s too late to do it now, don’t wait until winter comes to implement it and regret it later.
Winter maintenance of roses is mainly for flower lovers in the north. If you don’t have a greenhouse or sunroom, it is recommended to overwinter outdoors in winter and let it sleep normally. For areas in Henan and Shandong, roses or roses can overwinter normally in the open air, but in winter It is best to plant in a south-facing, sunny, and leeward location, otherwise the cold wind will dry out the rose or rose branches.
Some florists put roses or roses indoors in winter on an east-facing or south-facing balcony, which will get good light, but the roses will not grow well because if roses want to grow vigorously, the minimum temperature must be above 10 degrees Celsius, and It requires sufficient sunlight, at least 4-6 hours of light. This condition is difficult to achieve indoors, unless it is in a greenhouse. The main problem indoors is insufficient light and dry air, which will breed red spider mites. If you have raised roses indoors in winter, You will know that red spider mites are a real headache. Therefore, if you have a greenhouse or sunroom that can ensure better lighting and nighttime insulation conditions in winter, you can maintain them and bloom normally in winter. If you only place them on the balcony indoors , I still recommend letting it sleep normally outdoors, and it will bloom better the next spring.
