Management methods for roses during hot and rainy seasons
The reason potted roses die in summer is mostly because the potting soil was not mixed well, the pots were not repotted and the soil was not changed in spring, and the nutrients in the original potting soil were largely depleted. As a result, the roses cannot withstand the high temperatures and die. In the high-temperature summer season, roses are almost in a semi-dormant state. Some people see that roses do not bloom or bloom little and think it is due to insufficient fertility, so they apply more fertilizer and concentrated fertilizer. In addition, the high summer temperatures accelerate the fermentation of the fertilizer, and the rose roots are burned. After repotting and changing the soil, place it in a cool place for about a week before resuming normal

How to care for roses? Master these four key points
The rose is a plant that loves sunlight very much; if there is not enough light, it is very difficult to get it to bloom every month. To make roses bloom year-round, you must grasp the following four keys. (1) Sunlight must be sufficient: the place where roses are planted must be both well ventilated and able to receive more than half a day of sunlight; this is the primary condition for them to bloom in profusion. (2) They must be pruned often: even if the sunlight conditions are good, roses will not grow well if they are not pruned for a long time. The pruning method is: after December each year, when the rose leaves fall, prune once; after May, each time a round of flowers finishes blooming, cut away 2/3 or 1/2 of the branch that has bloomed, so there will be more chances for new flower buds to regenerate. The wounds caused by pruning should be sealed promptly with healing and antiseptic membrane to prevent the wounds from drying and cracking and from damage by pests and diseases, and to promote the rapid growth of callus tissue.
