Growing soil: loose and fertile soil with good drainage.
Growth temperature: about 25 degrees Celsius is the most suitable, and it can also be cold-resistant, such as MINUS 25 degrees Celsius.
Lighting conditions: roses are very fond of light, so they must be cultivated in a place with sufficient light. If roses don't get enough light in the growing season, it will lead to the phenomenon that their stems and leaves don't bloom.
Precautions:
(1) Watering method: When watering in summer, because the roses have been exposed to the sun all day, watering can only be carried out after 5 pm. Rose is a drought-tolerant plant, so water less in rainy season, pay attention to drainage, and keep the soil loose and fertile at all times. Every year when roses are about to enter hibernation, they should be roughly pruned, then fertilized and watered. Always pay attention to its ventilation and drainage.
(2) Fertilization method: Nitrogen fertilizer can be applied when the rose just germinates; After flowering, add some phosphate fertilizer and potassium fertilizer in the middle of nitrogen fertilizer application; When leaves fall in autumn, organic fertilizer is mainly applied. Roses like to grow in fertile soil very much, but there are no very strict requirements. Everything depends on the specific situation of your reproduction.
(3) Potting: It is best to put pots in early spring. You need to water it every day in summer, and water it thoroughly every time. As for pruning, it must be done in the dormant period of flowers. The advantage of this is that it grows better in the second year and the flowering period is longer. Also, when a flower is in full bloom, remember to pick off the withered flower.
(4) Pruning method: Rose is a fine variety plant, and the pruning method is also very simple. For example, every time a rose blooms, two-thirds of its branches must be cut off. In winter, just cut it to a height of 10 cm above the ground. Don't say you can't bear to part, it's no use cutting a little! I will grow very fast next year!
(5) Pest control: The most common disease of roses is white mold. Especially in rainy weather, the air humidity is relatively high. Rose leaves get sick easily. Don't worry too much at this time. Buy some medicine for white mold.
Do it. As for aphids, it is even simpler. Take a proper amount of white wine and dip it in the leaves with a cotton swab, and the aphids will fall off. Just pay attention to cleaning, and it is best to choose white wine above 50 degrees.
(6) Drought tolerance and waterlogging avoidance: Almost all plants are afraid of waterlogging. Potted plants, in particular, are the easiest to accumulate water. Once the potted plants are seriously waterlogged, the roots of the plants in the pots are easily soaked. Once the root of a plant is broken, basically the plant is not far from death. The same is true of roses. Don't let them get wet outdoors when it rains heavily. Better bring them in. If you forget it carelessly, you must remember to do a good job of drainage afterwards.
