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.

(3) Fertilize frequently and in a timely manner: generally, newly planted or transplanted potted roses can be grown in loose loess rich in humus. After May comes the peak growing season for roses; every 10 days, apply topdressing once, and stop fertilizing by November. If this fertilizing step is handled well, it can overcome their weakness of fearing high temperatures in summer.

(4) Prevent pests and diseases in a timely manner: in spring, roses are prone to aphids, which can be sprayed with water soaked with cigarette butts or with trichlorfon diluted in water; in summer, they are prone to black spot disease and powdery mildew, both caused by excessive moisture and muggy heat. For mild cases, some diseased leaves can be removed; for severe cases, spray once every 10 days or so with new high-fat membrane + Bordeaux mixture or thiophanate-methyl, sterilizing agent, etc. 2-3 times for control.
