There are three reasons for the rotten roots of water-raised chlorophytum. First, the water quality problem, long-term non-replacement of water is polluted or anoxic, so that the root system is easy to rot. Second, too much fertilization, plants can not absorb, easy to burn roots, resulting in fertilizer damage leading to root rot. Third, the temperature is too low. It itself is not cold-resistant, water should pay more attention to the low temperature environment, less than 5 degrees will be frostbite, root rot. No matter what the reason is, the rotten roots should be dealt with in time, cut off the rotten roots and strengthen management.
1. what fertilizer to use
Clivia in the seedling, the main is the use of nitrogen fertilizer, can promote better growth of the plant leaves, usually 10-15 days of fertilization once.After the seedlings are established, the use of nitrogen fertilizer should be reduced, mainly phosphate fertilizer and potassium fertilizer, and organic fertilizer can also be applied, which is helpful for their flowering.During the flowering period, potassium dihydrogen phosphate can be sprayed to make the flowers open bigger and the color more bright.
It is very important to choose the weather for fertilization of Clivia miniata, not rainy weather and strong light weather, because at this time the plant's ability to absorb nutrients is relatively weak, it is easy to produce fertilizer damage.
2. Propagation Method
1. Sowing method: First prepare the high-quality seeds, then put them into warm water, soak them for about half an hour, take them out, and dry them for about 1-2 hours, and then sow them.It can also be soaked in 10% sodium phosphate solution for about half an hour, and then soaked in clean water for 10-15 hours.When sowing seeds, put it in the soil, and then cover it with soil and put it in a ventilated place.
2. Plant division method: Prepare the sterilized earthen pots and media in advance. Take out the plants first and clean up the mud balls on the roots.Then use scissors to separate the sub-plants from the mother, then smear with charcoal powder to avoid decay, and finally plant them, and the root system can grow in about 1-2 months.
