How to grow potted Chinese roses well
Some flower friends asked, their Chinese rose plant has yellow leaves but also sprouts new buds and grows vigorously. What's going on? What should I do? Chinese roses are relatively easy to care for, have strong growth ability, enjoy sunlight, and also prefer sufficient water and fertilizer. They can be planted both in the ground and in pots. Therefore, they are very easy to cultivate and are a favorite among many people. In response to the questions raised by friends, I carefully examined the pictures several times and feel there are several possible reasons. At the same time, I offer my own opinions and suggestions for reference, and the specific situation is analyzed as follows.
One, reasons for the yellowing of Chinese roses
I found that this potted Chinese rose is grown outdoors. Because it is a pot-grown plant, it is affected by sunlight, water, soil, and pot size, etc.
1. Excessive rainfall, moist potting soil easily accumulates water, which is a main reason.
This year, at the end of summer and the beginning of autumn, there was a lot of rainfall, almost non-stop. A heavy rain occurred yesterday, and everywhere was filled with water. Although potted Chinese roses have a strong tolerance to moisture, continuous rainy weather will inevitably cause excessive moisture in the potting soil, leading to waterlogging. If the roots of the Chinese rose are soaked in water for a long time, it can cause the leaves to turn yellow and new buds to grow excessively; in severe cases, it can cause the leaves to fall off, the roots to rot, and ultimately death. I saw that this potted Chinese rose is in a plastic pot, which has poor breathability; if the bottom hole is too small and the water flow is slow, it is more likely to cause waterlogging, affecting the healthy growth of the Chinese rose.
Comprehensive analysis: The potting soil in the potted Chinese rose is moist, indicating obvious overhydration or waterlogging. It has already caused the branches and leaves to turn yellow and the new buds to show signs of excessive growth.
2. Frequent cloudy weather, humid air, and high humidity are secondary reasons.
Outdoor pot-grown Chinese roses are greatly affected by the weather. Of course, if grown underground, they are generally not affected, as their root systems are very developed, deeply rooted, and even continuous rainy weather does not cause major issues. Because the water will quickly drain away and not form waterlogging. However, potted Chinese roses do not have this condition or advantage. Suppose, like the current rainy and cloudy weather this year, the air is humid, the water drainage is not smooth, forming long-term moist soil, combined with daily cloudy weather, poor air circulation, and rare sunshine, it will inevitably affect the healthy growth of the Chinese rose.
Comprehensive analysis: This autumn has had a lot of rain, almost daily cloudy weather, humid air, and very high humidity. The continuous rain has already formed waterlogging, combined with cloudy weather and no sunshine. This also affects the growth of the Chinese rose and causes yellow leaves.
3. Lack of sunlight, slow evaporation of water, affecting normal growth, is another factor.
Chinese roses are generally flood-tolerant and usually do not have major issues. However, after forming waterlogging, if there is continuous cloudy weather without sunshine, it is not conducive to water evaporation; especially if placed in a shady place with poor ventilation, it will further increase soil moisture and is difficult to dry in a short time, easily causing a long-term moist state, resulting in abnormal growth of the Chinese rose and worsening yellow leaves.
Comprehensive analysis: Sunlight is a necessary condition for the growth of Chinese roses, and they are not afraid of sunlight. Even in the hot summer, they can grow normally. However, without sunlight, the soil will be difficult to dry due to excessive rain, affecting growth.
Two, adopt the method of changing location to deal with
It is not可怕 for Chinese roses to have yellow leaves, the key is to take corresponding measures, treat them symptomatically, and promote the early recovery and normal growth of the Chinese roses.
1. Move indoors during rainy days.
Outdoor pot-grown Chinese roses require careful care. Adjust according to weather changes at any time. If the weather forecast shows continuous rainy weather, move the Chinese roses indoors to prevent continuous rain from causing waterlogging in the pots, leading to yellowing of the branches and leaves, excessive growth, and even root rot and drying death. Of course, if it rains occasionally, the time is short, and it quickly becomes sunny, there is no need to move around. It can even supplement water and increase nutrients, which is a good thing. The key is not to exceed the watering limit, as excessive water will naturally affect growth.
2. Move to a well-ventilated area during cloudy days.
If the potting soil of outdoor-grown Chinese roses is too moist, it can cause waterlogging. Although it has not rained, continuous cloudy weather with humid air is not conducive to soil drying. At this time, you can consider moving the Chinese roses to a place with a breeze for ventilation and dispersion, which also works well. The action of wind speed accelerates soil drying; at the same time, it provides good ventilation and breathability for the Chinese roses, promoting leaf growth, preventing leaf yellowing, and long, thin branches.
3. Place in a sunny area during sunny days.
Too much rain is not可怕, and continuous cloudy days are also not a problem, the key is to have sunlight. If excessive watering or heavy rain has caused waterlogging and yellowing of the leaves, the best solution is to increase sunlight. Don't worry that after many days of cloudy weather, sudden exposure to sunlight can cause the leaves to burn. Chinese roses are relatively sturdy, especially now that it is autumn, and the sunlight is not as intense as in the summer, so they can be exposed to full sunlight. Of course, if it is summer and the Chinese roses are suddenly exposed to strong sunlight after long periods of rainy weather, it is not advisable, so be careful to distinguish.
Three, take corresponding remedial measures
Excessive rain or watering can also be remedied with corresponding technical measures.
1. Remove the yellow leaves.
The yellowed leaves of Chinese roses affect the aesthetic appearance and also impact subsequent growth. It is recommended to prune. Mainly remove the yellow leaves of the Chinese rose, and look! This potted Chinese rose has yellow leaves at the bottom, which are no longer beautiful and can be pruned with confidence. This can promote healthy growth and enhance the ornamental value. Act quickly! Remove the yellow leaves of the Chinese rose.
2. Loosen the soil.
When the potting soil has excessive moisture, is too moist, or is in a waterlogged state, you can find a stick and turn the potting soil over. Of course, don't turn it too deep to avoid damaging the roots. This can loosen the soil, making it more breathable and promoting respiration. It can also promote rapid drying of the soil, remove moisture, and is beneficial to the growth of Chinese roses. If excessive watering occurs, it is recommended to loosen the soil promptly to increase soil breathability and dryness.
3. Dry the roots and change the soil.
If the watering is too excessive and the potting soil is difficult to dry, remaining in a long-term moist state, it can cause adverse effects on the Chinese rose. If various measures have been tried and the effect is not significant, you can consider pulling out the Chinese rose and placing it in a shady place to dry. If there are rotted parts of the roots, you can trim them appropriately; you can also use a solution of carbendazim to soak the roots for disinfection. At the same time, you can replace the moist soil with relatively dry soil, which is beneficial to the healthy growth of the Chinese rose.
