In summer, it should be kept in a semi-cool environment. It needs plenty of sunshine in winter. If it is placed in a sunny place indoors, the temperature should be kept above 10℃, and if it is lower than 10℃, it is easy to cause freezing injury.

Fertilization method:

During the growth period of Gulong Flower, apply light fertilizer once every 1520 days. The fertilizer can be granular compound fertilizer or self-made alum fertilizer. But the fertilizer should not be too thick, so as not to cause fertilizer damage and lead to rotten roots.

Trimming and shaping:

In order to prevent plants from premature aging, they should be pruned frequently. Cut off some old branches that don't bloom, and at the same time remove the weak buds that grow below, so that their terminal buds can fully develop and elongate.

Matters needing attention in flower cultivation of Gulong

In the process of cultivation, Longgu Flower is vulnerable to soft rot, stem blight and other diseases. In the early stage of soft rot, brown spots appeared on the column and gradually spread around, then the diseased part softened, the epidermis was eroded, and a viscous foul liquid flowed out. Soft rot develops rapidly, and the whole plant can die in only two or three weeks, but the plant does not lodging and needs to be controlled.

At the onset of stem blight, the whole circle at the bottom turned pale yellow, then spread upward, the green part gradually faded to beige, and white mildew spots grew on the epidermis. After that, the inside of the column was completely rotten, leaving only the epidermis in a dry state, which was broken with a gentle poke by hand, with mucus flowing out, but no stench. Stem blight has also developed rapidly, with some damaged plants lodging and some not lodging.

For soft rot, stem blight and other diseases, the pot soil can be disinfected, such as insolating for 2 ~ 3 days, or scalding with boiling water 1 ~ 2 times. Soak the soil with 500- 1000 times of carbendazim, oxazole, thiophanate-methyl, benomyl and other solutions, and spread the treated soil for one week. It is best to use a new flowerpot, and the old flowerpot should be disinfected if used.
