How to raise blue flower dan

1. Maintenance methods

1. Temperature: It has poor resistance to high and low temperatures. The temperature suitable for its development is between 17 and 25 degrees. The maximum high temperature is 30 degrees and the maximum low temperature is 8 degrees. If the temperature exceeds the limit temperature, the health of the plant will be affected. Therefore, heat dissipation needs to be done well in hot weather, and outdoor cultivation should be avoided when the temperature is too low, and it should be maintained indoors.

2. Watering: It likes moisture and has a very high demand for water, but it is not tolerant to waterlogging. Before watering it, you need to observe the condition of the soil. If the soil is completely dry, you can water it. If the soil is wet, do not water it for the time being. The water for watering should be tap water that has been dried in the sun. It cannot be directly released for irrigation.

3. Fertilization: Its growth rate is very fast, especially during the growth period, and the consumption of nutrients is very fast. The nutrients in the soil alone are not enough, and nutrients need to be supplemented. In addition to chemical fertilizers, you can also use liquid nutrient solution or homemade fertilizer to supplement nutrients, and the frequency of use should be once a week.

4. Light: It needs sufficient light to grow. The sunlight at noon in summer is relatively strong, so it needs shade. It can get normal light at other times.

2. Breeding techniques

1. Reproduction: Its general method of reproduction is sowing. Sprinkle the seeds into the prepared soil, water them thoroughly, and then cultivate them in a place with high temperature and weak light. Seedlings will emerge in about a week. Once it has three leaves, it can be planted.

2. Pruning: During the growth process, it is inevitable that there will be broken branches and leaves. Once this is found, it is necessary to prune in time to avoid affecting the normal branches.

3. Problem Diagnosis

1. Blackening of leaves: If the leaves turn black, it is likely that there is insufficient light, and you need to increase the lighting time. It is important to note here that the process of increasing lighting is slow and gradual.

2. Root rot: If the plant has root rot, you need to dig out its roots, trim off the rotten parts, and then disinfect them with disinfectant. After the cut is slightly dry, you can replant it in the potting soil.
