The benefits and precautions of roses getting rained on
You may not be familiar with the introduction of roses, such as the benefits and precautions of roses getting rained on. Here is the detailed introduction:
Although most rose enthusiasts grow their roses on balconies and rarely get a chance to let them get rained on, it is believed that all rose lovers are more inclined to appreciate nature. Therefore, it is occasionally possible to encounter potted roses getting rained on. This article is a summary of the benefits and precautions of roses getting rained on by rose enthusiasts, which can also be applied to other plants for flexible reference.
Benefits of roses getting rained on:
1. Rain can saturate the water in the potting soil, which is an effect we can only achieve by evenly and slowly spraying with a watering can. This is especially beneficial when there are many flowers, as we usually don't have the patience or energy.
2. Since the air contains carbon dioxide, which can dissolve in rainwater to form carbonic acid, rainwater is usually slightly acidic, which is the preferred growing environment for roses. This is why we add ferrous sulfate to the potting soil.
3. The air is rich in oxygen and nitrogen, which are absorbed in large amounts by rainwater, making it nutritious.
4. The prerequisite for rainfall is the presence of condensation nuclei (i.e., dust particles) in the air, which are rich in various trace elements essential for plant growth.
5. Nitrogen in the air is not easily absorbed by plants and needs to be converted into nitrogen compounds. Thunderstorms can cause nitrogen in the air to react with rainwater to form nitrogen compounds, making rainwater an excellent natural nitrogen fertilizer.
6. Rain can wash the plants, clearing the pores on the plant surface blocked by dust, promoting plant respiration, accelerating metabolism, and helping your roses grow faster and healthier.
7. Chlorine in tap water (disinfectant) is harmful to the growth of roses (and most plants), while rainwater irrigation undoubtedly avoids or reduces this harm.
Precautions for roses getting rained on:
1. Young rose seedlings that have just been planted should not be rained on. Since their root systems are weak, they need to quickly dry out and then get wet to encourage new roots to grow. This is why it is not recommended to use large pots for young seedlings.
2. The potting medium needs to be loose and well-draining. If the water retention is too good, consecutive short intervals of rain can cause waterlogging in the potting soil, leading to root rot. The general standard is that when watering, the water should quickly fill the pot and completely seep into the soil within no more than 10 seconds, otherwise, the potting soil needs to be improved, of course, provided there are no cracks in the soil or pot combination.
3. The best method is to let the roses get rained on every three to five days. However, we can't control the weather. If there is continuous rainy weather for several days, it's best not to let the roses get rained on to prevent waterlogging. Also, if the potting soil is not well-draining and causes waterlogging when watering, even the most pleasant rain should not be allowed to let the "beauties" go out and "get wet."
4. Although roses prefer acidic conditions, for heavy industrial areas with severe air pollution, the rain may be too acidic (so-called acid rain), exceeding the tolerance level of roses. Therefore, rose enthusiasts in these areas need to be cautious.
5. During heavy rainstorms, potting soil may be splashed out, revealing the "white feet" of the "beauties," which is not elegant. In this case, it is appropriate to place some isolating materials on the surface of the potting soil, with large particle陶粒 being suitable.
6. After the rain, you should promptly check the entire rose plant. Rain may wash off leaves infected with fungi, leading to black spot diseases. In this case, you need to spray the corresponding type of fungicide promptly, and switch to different ones if one doesn't work well.
