The 4 Common Challenges in Deep Autumn and Early Winter Rose Maintenance
For many girls, the content of planting green plants and flowers, such as the 4 common challenges in deep autumn and early winter rose maintenance, will be shared in detail next.
This autumn is unusually hot. With this temperature drop, we suddenly realize that it's already winter. In just a few days, the season has transitioned from summer to winter. At this time, we need to adjust our rose maintenance methods promptly. Today's article will focus on solving the 4 major issues faced by rose enthusiasts recently.
1. What should we do if the roses have a lot of yellow leaves?
In the past few days, many rose enthusiasts have found that their roses have suddenly developed many yellow leaves, causing them to panic and ask what kind of medicine to apply. In fact, during deep autumn and early winter, roses are prone to yellowing leaves, especially after a sudden temperature drop, when roses tend to shed a large number of metabolic yellow leaves. There's no need to worry; just remove the yellow leaves and clean them up.
Metabolic yellow leaves usually occur on old leaves, but if new leaves also develop many yellow leaves, it's time to consider the maintenance issues, such as fertilizer damage, drought, or nutrient deficiencies. Metabolic yellow leaves are the most common in this season.
2. Should roses be insulated when the temperature drops?
This time the temperature drop is significant, and many rose enthusiasts are worried about whether their roses will be frozen outside. Roses have good cold resistance, and potted roses can survive at -10 degrees Celsius without being frozen or damaged. Therefore, in most regions, roses do not need to be brought indoors for overwintering.
If your potted roses are currently full of flower buds and you want these buds to continue blooming, you can bring them indoors and place them on a south-facing balcony to maintain a relatively warm environment, allowing the rose buds to bloom quickly.
However, roses in a poorly ventilated indoor environment are more prone to pests and diseases. Before bringing them indoors, it is recommended to spray a comprehensive fungicide and insecticide, and then bury insecticide and fungicide granules shallowly in the potting soil to significantly reduce the incidence of pests and diseases after entering the house. After moving indoors, it is also necessary to maintain good ventilation and reduce watering, as excessive watering in a poorly ventilated environment can cause root rot.
3. How to prune roses after they have bloomed?
Rose enthusiasts know that frequent pruning is necessary to keep roses blooming. So, how should we prune the roses after they have bloomed? Do we need to cut back the branches?
I think pruning should depend on the region, with different regions adopting different approaches.
If you are in Guangdong or Guangxi, where the winter is relatively warm, and roses continue to bloom without dormancy, you should prune according to the standard post-bloom pruning.
If you are in a frost-prone area, such as Jiangsu, Zhejiang, and Shanghai, and the rose flowers have faded, it is recommended to prune only the spent flowers or not prune at all.
Because in Jiangsu, Zhejiang, and Shanghai, winter is not very cold, and the current temperature allows roses to continue growing. Prompt pruning of spent flowers will stimulate the terminal buds to sprout quickly. If the branches sprout in cold regions, they will definitely not bloom and will only waste nutrients. Therefore, the suggestion from the Green Plant Enthusiast website is not to prune and let them grow naturally.
Of course, the above information from the Green Plant Enthusiast website refers to outdoor rose maintenance. If you keep your roses indoors during winter, that's a different story.
4. Can we use lime sulfur solution to clean the garden if the roses still have flower buds?
The other day, the Green Plant Enthusiast website shared an article about cleaning roses in the garden, and many enthusiasts said that their roses still had many flower buds and were afraid to use lime sulfur solution.
In fact, cleaning the rose garden is not directly related to the presence of flower buds but is more closely related to the temperature. Although our roses are growing flower buds and look tender, they have matured after experiencing low temperatures and have the ability to withstand. Spraying lime sulfur solution on the rose buds will not cause any significant damage. At most, a high concentration of lime sulfur solution may leave a residue on the leaves or petals, making them look unattractive.
So, there's no need to worry. Clean the garden when necessary, and adjust the concentration of the lime sulfur solution according to the temperature in your area.
