Abstract:Longevity flowers are loved by people, but they are prone to black stem problems, which may be caused by stem rot, especially in the summer high temperature season. It is recommended to prune the black rot part as soon as possible and re-cutting, the temperature is suitable, and the rooting will recover soon. Longevity flower maintenance should pay attention to the loose and breathable soil, not too much watering, and put it in a cool and ventilated place in summer.
Longevity flower is a perennial succulent plant of the Sedum family, the leaves are thick and round, the flowering period is long, the flower color is rich and colorful, the maintenance is relatively simple, and it is deeply loved by people.
When we maintain, we may be the first to find the phenomenon of yellow wilting and weakness of the leaves of longevity flowers, and if we carefully check it, we will find that it may be caused by black rot of longevity flower stems. Longevity flower black stem is mostly caused by stem rot, but also often accompanied by leaf blight, stem rot is often caused by potting soil compaction sticky, poor drainage, wounds caused by insect pests, and a series of reasons such as poor ventilation and insufficient light caused by fungal erosion plant infection. It can occur in the above-ground part or below the soil surface, and it is more common in the summer high temperature season, but it can also occur in other seasons. So if a black stem occurs, how to deal with it and recover it as soon as possible?Here, I would like to share my views with you:
The black stem is caused by bacterial infection, and the appearance of symptoms indicates that the damage has been caused to the plant, and the water and nutrient conduction tissues of the stem are damaged, and the conduction function is weakened or even disappeared, and the damage is generally irreversible. Therefore, when the longevity flower plant has symptoms such as leaf wilt and weakness, once it is confirmed that it is a black stem, it is recommended to deal with it decisively, if it is a part of the twig black stem, prune it as soon as possible, if it is the main stem black stem, prune it as soon as possible and change the cuttings, to prune the black rot part, to the green healthy tissue. When the temperature is right, longevity flower cuttings are easy to take root and are fast, and even budding cuttings can bloom alive. I had a pot of longevity flowers in late October and found that the stalks were black rot, and after pruning, I re-cut them, which were with buds at the time, and they recovered very quickly, and now they have begun to bloom.
Some people also suggest that after the appearance of black stems, they should be controlled by medication, but I think that drugs can only control the development, and the damage caused before is difficult to recover, so it is recommended that fungicides such as carbendazim and dimethyl are better used in prevention.
Longevity flower is a perennial succulent plant of the Sedum family, the root system is not very developed, drought tolerance and stain resistance, pay attention to the maintenance, the soil is loose and breathable, watering can not be too much, pay attention to dry and wet alternately, a little drier, in summer, pay more attention to put it in a cool and ventilated place, do not rain. In other seasons, it is necessary to have sufficient sunlight to grow strong and bloom more.
