The main purpose of doing this is to reduce water evaporation.
This article introduction: How should Chinese roses be acclimatized and the introduction of green plants and flowers that die a few days after repotting, with specific details as follows:
Yesterday, I shared different methods of potting Chinese rose seedlings with different conditions, actually potting is not difficult, it's simple once you master the key points. Many flower friends' Chinese roses die after repotting mainly because the acclimatization method is incorrect.
So, how should Chinese roses be acclimatized?
Everyone should have heard:
Acclimatization should place the seedlings in a shaded and ventilated area and should not be exposed to direct sunlight.
This is true for most flowers, especially some herbaceous flowers, which should avoid direct sunlight after repotting and then be exposed to the sun after 3-5 days of acclimatization.
The main purpose of doing this is to reduce water evaporation.
Herbaceous flowers naturally have a higher rate of water evaporation, and after repotting, the damaged roots often have a reduced ability to absorb water. If exposed to direct sunlight immediately, the rapid evaporation of water can easily lead to dehydration and wilting of the plant.
Should Chinese rose seedlings also be handled in this way after repotting?
Actually, no. The acclimatization method for Chinese rose seedlings is quite the opposite of that for herbaceous flowers!
Chinese rose seedlings can and should be exposed to sunlight after repotting, and not being exposed to the sun for a long time can even lead to their death.
Why is that?
This requires an analysis of the growth habits of Chinese roses.
Chinese roses are very fond of sunlight and require at least 4 hours of direct sunlight a day, even during hot summers, they can withstand full sun exposure without a problem.
(Of course, if the sun is too strong, it is recommended to provide some shade during the noon of summer for better growth of the Chinese roses.)
As a sun-loving flower, sunlight is its main source of nutrients.
Generally, Chinese rose seedlings purchased online are kept in dark packaging boxes during shipping. Due to the lack of sunlight and photosynthesis in the dark environment, the roses need to consume their own nutrients to maintain growth.
For example:
This is similar to our dieting for weight loss. Chinese roses that are kept in the dark for several days without sunlight exposure is like us not eating for two days.
Think about how you would feel after not eating for two days?
The newly received Chinese rose seedlings, after not being able to photosynthesize and replenish nutrients for a long time, are as weak as we would be after not eating for two days.
If they are not exposed to sunlight after repotting, the roses will not get effective nutritional supplements and will be无力 to grow.
The lack of nutritional supplements is just one reason. Additionally, Chinese roses may also rot due to poor root respiration.
Why do I say that?
Think about it, do we not water indoor potted plants less frequently than outdoor ones?
For the same potted plant, the watering frequency is completely different when grown indoors compared to outdoors, with indoor plants being watered less frequently.
This is mainly because indoor potted plants are not exposed to direct sunlight and have a lower temperature, which results in a slower rate of transpiration and less water consumption.
Also, the air circulation indoors is much poorer compared to outdoors, which directly determines the drying and wetting cycle of the potting soil.
Chinese roses are flowers that are not drought-tolerant and are afraid of waterlogging. The potting soil that remains moist for a long time can easily lead to root rot and death.
If the repotted Chinese rose seedlings are placed in a shady area, they will not be able to perform effective photosynthesis and get nutritional supplements, and the potting soil may remain moist for a long time, easily causing root suffocation.
Therefore, it can be said that the acclimatization method for Chinese roses is completely opposite to that for herbaceous flowers. Herbaceous flowers should avoid direct sunlight, while Chinese roses need ample sunlight.
So, does it mean that all Chinese rose seedlings can be placed directly in a sunny area after repotting?
If it were that simple, there would be no need to write a separate article to complicate things.
Acclimatizing Chinese roses to sunlight still needs to be done according to the condition of the seedlings and the weather conditions, and it cannot be generalized.
If you only read this article and then rashly place all repotted Chinese rose seedlings in direct sunlight, and they die, don't blame anyone else.
So, which seedlings can be exposed to the sun?
Which seedlings cannot?
Is it okay to expose them to the sun all day, or just for a short while?
Due to limited space, these questions will be addressed in detail in tomorrow's article.
The above sharing on how Chinese roses should be acclimatized and the purpose of reducing water evaporation, as well as whether Chinese rose seedlings should also be handled in this way after repotting, hopes to provide you with help in green plant management!
