How to care for Chinese roses in winter?
About the explanation of how to care for Chinese roses in winter in the aspect of green plants and flowers, the following editor will give you a detailed answer.
Many novice flower lovers are curious about how to care for Chinese roses in winter, so today I'll briefly talk about the maintenance methods of Chinese roses in winter.
In areas with frost, including the Zhejiang and Shanghai mail area, Chinese roses will enter a dormant state in winter. When the temperature is below 0 degrees, they often stop growing, turn yellow, shed leaves, and finally become bare stems.
If the leaves have fallen, it means that they are already dormant. You only need to place the potted Chinese roses in a sunny and sheltered area to allow them to receive ample sunlight. When the soil is too dry, water the potted plants at noon when it's warm, making sure to water thoroughly to avoid half-watering.
Not counting the cold regions of Jiangsu and Zhejiang
In the Jiangsu and Zhejiang area, the temperature is not very low. Like this warm winter, so far, although it is already December, the temperature is still relatively high. Chinese roses continue to grow and bloom. Some flower lovers' Chinese roses are still growing flower buds, and many eager-to-prune flower lovers are纠结 about whether to cut or leave them.
Actually, at this time, whether the Chinese roses are growing branches or already have flower buds, they should be treated with the same attitude, which is to wait and see.
Winter temperatures can drop rapidly. Even if there are flower buds, they may not bloom. But if pruned in advance, it might not cool down for a long time, leading to the sprouting of new buds. New buds have weak frost resistance, and if they encounter cooling after sprouting, it can be quite fatal. So, I advise all eager flower lovers to wait a bit longer before pruning.
As for fertilization, you can apply two doses of phosphorus-potassium fertilizer, which is beneficial for root growth and can enhance the resistance of Chinese roses, making them more likely to survive the winter. As for nitrogenous fertilizer, it can be used less or not at all since the growth is already very slow and the consumption is low.
In the Zhejiang and Shanghai area, many times Chinese roses do not shed leaves even when they enter the dormant period, especially some climbing Chinese roses and shrub varieties that do not shed leaves. But as soon as the branches and leaves of Chinese roses turn dark red, it means they have entered the dormant period. We can remove all the leaves one week before pruning to promote the expansion of the bud points and make it easier to observe the robustness of the buds for pruning.
Winter maintenance in southern regions
For southern regions, Chinese roses do not have a dormant period in winter. They not only do not go dormant but also continue to bloom. However, to maintain the shape and energy for blooming, it is also appropriate to prune Chinese roses in winter.
The timing of pruning should be during the coldest period of Chinese roses, usually in mid-to-late January. At this time, the temperature is lowest, and the growth of Chinese roses is slow. Pruning most of the branches and leaves will not have a significant impact on the overall growth of the plants.
However, the pruning should not be as severe as in dormant regions, but rather leaves should be retained to allow photosynthesis and nutrient production.
For weak Chinese roses, pruning is not suitable. Instead, layering can be used to promote new branches at the base, achieving rejuvenation of the plant. When new branches grow and mature, the old branches can be pruned to maintain an elegant plant shape.
Winter fertilizer for Chinese roses
In addition to pruning Chinese roses in winter, it is recommended that you give them a winter fertilizer.
In cold regions, organic or compost can be covered on the soil surface at the beginning of winter to provide insulation.
In the Jiangsu and Zhejiang area, you can give the ground-planted Chinese roses a dose of raw fish intestine fertilizer in the coldest month of January. Dig a pit around the roots of the Chinese roses, fill it with fish intestine, and cover it tightly with soil to prevent cats and dogs from digging it out.
In southern regions, whether ground-planted or potted Chinese roses should be cautious with raw fertilizers and use fermented organic fertilizers buried shallowly.
Whether in the south or north, potted Chinese roses should avoid using raw fertilizers and should use fully fermented organic fertilizers. Of course, if you insist on using them, we won't stop you, as long as there is no fertilizer damage, you are the winner!
