Friends who are poisoned by Chinese roses always ponder how to plant Chinese roses. Although Chinese roses are famous for being "medicinal pots", it is actually easy to plant them once you understand them. This article is a friend's experience in planting Chinese roses, which is very helpful for friends who want to plant them!
I. Planting Chinese roses, first choose the right soil
The root system of Chinese roses needs water, oxygen, and nutrients in the soil, so the soil for planting Chinese roses should take care of these three points. Some soil is very sticky and rich in nutrients but not breathable, which can cause root rot. Some growing materials are very loose and breathable, but lack nutrients, which can lead to poor growth. The best is the so-called granular structure soil. The method of making this soil is to take some garden soil, mountain soil, or used soil, mix it with animal manure and bodies, cakes, and plant leaves and fruits, and bury it well without covering the top, leaving it outside for wind and sun exposure. After a long time, it will naturally grow weeds, and it doesn't need to be managed. After a year, it becomes fertile soil with a granular structure.
The granular structure, to put it simply, is that the glue decomposed from organic matter can stick powder into small soil particles. This soil is rich in organic matter, has a certain water retention capacity, and has spaces between the soil particles, perfectly solving the problems of water, oxygen, and nutrients. Or many families don't have the conditions to make it. Then, several types of soil can be mixed. For example, if there is very sticky pond mud or garden soil, the pond mud can be dried, crushed, and the powder sieved out, then half of the cottonseed hulls or peat moss can be added. Both cottonseed hulls and peat moss can prevent excessive adhesion of pond mud and garden soil particles after heavy rain, which is like we need to stick dry flour on the outside of dumplings, and both are rich in nutrients. But it is recommended not to use too fertile pond mud.
Actually, there is another type of soil that has always worked well, that is, the red soil in the south. Pure red soil is very sticky, but if it is dried, crushed, and sifted, and mixed with peat or decomposed leaf soil, it is very useful. Many bought peats are not easy to wet when dry and hard to dry when wet, especially in the Yangtze River Valley, where using pure peat during the rainy season is not ideal. Adding three to four parts of red soil can solve this problem. Red soil absorbs less water and dries relatively quickly. It is also acidic, adding some of it can ensure the slightly acidic nature of the potting soil. Not to mention Chinese roses, I also add some of this soil when planting orchids, and the roots grow well. Many sources say that Chinese roses like sandy loam, but this sandy loam is not adding sand. Sand cannot solve the problem of compaction; compacted soil will still compact even after adding sand, because sand is too fine and cannot prevent soil from sticking together unless a lot is added, which would then lack nutrients. The role of sand is to regulate moisture, because sand does not absorb water. If very water-absorbent material is used, adding sand can make it dry faster, rather than not drying for several days after rain and阴天.
The choice of soil also depends on the environment. If you want Chinese roses to wrap the pot in a short time on the balcony as they do in the open air, the soil used will be different. In the open air, using a clay pot with pure peat may be fine because of sufficient light and ventilation, and it dries quickly, with strong plant growth and more water absorption and evaporation from the leaves. But in a poorly ventilated balcony, the root growth may be slow. The growth of roots requires alternating wet and dry conditions. In this case, the soil should have more breathability and nutrients than water retention. For example, the amount of soil can be more than that of peat.
If the soil is prone to compaction, simply adding perlite will still compact if the amount is small, and too much will lose many nutrient sources. Perlite is more suitable for peat or a mixture of peat and clay.
II. Watering and potting for Chinese roses
There is no fixed frequency for watering. It is different between raising them on a balcony and in a garden, and also different between the first floor and the tenth floor. Water when the soil surface is dry. Turn the pot over to see that the soil surface is dry, but the bottom is still slightly moist, not completely dry, even in the most breathable clay pots, of course, provided that the soil surface is not dry for several days, otherwise the bottom will definitely dry out.
Watering is closely related to the pot. The same plant and the same soil will dry at a different rate in a clay pot compared to a ceramic pot, and the difference is not small. Of course, using a clay pot is best for rapid root growth. If you choose a pot that is not breathable for aesthetics, you have to make adjustments to the soil, at which point you need a material that is more loose, breathable, and dries faster. Conversely, if a clay pot is paired with very loose and breathable soil, there is a problem of too fast water evaporation. In summary, the pot and soil should solve the problem of not drying too fast, nor always staying wet.
Watering in March and April is very good. Chinese roses that have been rained on in spring simply leap in growth, and the temperature is not very high at this time, and diseases have not yet occurred. Rainwater is rich in nutrients and oxygen, so even if it rains for十几二十 days in a row, Chinese roses will not rot the roots, but if you water for twenty days in a row, it is very dangerous. But too much rain from the end of May to June is not good. In Jiangnan, it is the rainy season, and the roots are fine, but the top of the soil can easily get black spot disease.
The size of the pot should match the size of the roots. If the environment is very ventilated and well-lit, a larger pot is fine, but if the environment is not very ventilated and only has four to five hours of sunlight, using a large pot for young seedlings will make them grow slowly. There is a saying that is very accurate: "a large pot makes the roots cold." The size of the pot is closely related to the moisture and temperature of the soil, and the moisture and temperature of the soil are closely related to the growth of the roots.
III. Fertilizer selection for planting Chinese roses
Chinese roses require the most nitrogen fertilizer. They need sufficient nitrogen fertilizer (G-Y) in spring. Chinese roses can bloom several times from spring to early summer, and new branches need to be grown before flowering after each bloom. Only in early spring, after the first new leaves mature and before budding, nitrogen fertilizer can have a higher proportion, and after budding, the proportion of phosphorus and potassium fertilizer can be increased. Ten to fifteen days before flowering, you can spray phosphorus and potassium fertilizer on the leaves. Before summer, you can slowly reduce nitrogen fertilizer (G-Y) and apply several times of phosphorus and potassium fertilizer to let Chinese roses accumulate enough nutrients to survive the summer. After entering summer, you can continue to fertilize, lighter and less frequent. Using organic fertilizer is safer at this time.
The base fertilizer for Chinese roses must be sufficient. It is best to use organic fertilizer. Organic fertilizer contains too many nutrients; I don't know how many and how much the Chinese roses need to absorb, and I don't know how many and how much the organic fertilizer contains, but these two are just right. I used to look for some information on this, and it seems that modern science has not completely solved this problem. The inorganic salts in chemical fertilizers are fixed, and I think they are not as flexible as organic fertilizers, which can meet more of the needs of Chinese roses. Generally, the base fertilizer uses decomposed animal manure or cake fertilizer. Foliar spraying cannot replace root absorption, so the fertilizer applied to the soil must be sufficient.
Fertilization also depends on the condition of the Chinese roses. If the branches are growing well, it means the roots are also growing well and need more fertilizer. Conversely, if the Chinese roses are not in good condition, it means the roots are not good either, and at this time, it is not a problem that can be solved by fertilizer, but by making the soil slightly dry and the air humidity slightly higher to grow the roots and branches well.
Urea is very good for foliar application of nitrogen fertilizer, but now high-nitrogen seaweed fertilizer seems to be better. Other compound fertilizers are used very little, not sure, and phosphorus and potassium fertilizers can be increased in autumn to accumulate nutrients for winter.
