We know that Catharanthus roseus likes the environment of astigmatism, so we should pay attention to avoid direct sunlight in summer and avoid exposing Catharanthus roseus to the sun, and it is best to breed indoors. Moreover, in terms of lighting, we must ensure four hours of lighting time, and the most important thing is to prune Catharanthus roseus in time. Therefore, Catharanthus roseus can be pruned in summer, and the core should be picked before flowering, and all the residual flowers should be pruned after flowering to ensure that Catharanthus roseus can continuously grow lateral branches after flowering.
Because Catharanthus roseus is a herb, it is suitable for potted plants, but its plants should not grow too high, so as not to affect decoration and appreciation. Therefore, after the survival of the upper pot, it needs to be picked many times to promote Catharanthus roseus to have more branches. After flowering, cut off the residual flowers and make appropriate pruning. Because Catharanthus roseus generally grows luxuriantly in summer, it is best to prune Catharanthus roseus in summer. When pruning in summer, you can prune the branches that are too dense, and only keep about 5 branches, focusing on pruning insect branches and dead branches, and at the same time strengthening water and fertilizer management to promote Catharanthus roseus to develop new branches and restore its growth.
In addition, Catharanthus roseus should also be pitted during the growing period. Generally, the coring begins when the true leaves are 4 ~ 6, and it is best to perform the second coring when the new shoots grow about 5, preferably no more than 3 times. It is best to remove the core about 4 days earlier in summer than in autumn. After flowering, the diseased branches, dead branches and rotten branches left on the plants should be pruned in time to avoid wasting nutrients and promote secondary flowering. Because Catharanthus roseus likes to grow in a high temperature and high humidity environment, it is generally better to cut off all the rotten roots, rotten roots and redundant fibrous roots on the old roots every other year to promote the concentration of nutrients in the roots.
Because Catharanthus roseus is sensitive to low temperature, it is necessary to maintain a good ventilation environment after pruning, water it in time to keep the soil moist, and then water a proper amount of urea solution and sufficient light to promote the growth and development of new shoots. If all this is done, our Catharanthus roseus will grow beautifully.
