How to grow Andrographis paniculata

1. Suitable temperature

Andrographis paniculata prefers hot and humid climate. It likes plenty of sunlight and fertile soil. When seeds are germinating and seedlings are growing, the suitable temperature is around 25~30℃. When the temperature drops to 15~20℃, the growth will be slow; when the temperature drops to around 8℃, it will stop growing. When the temperature drops below 0℃, all the plants will wither. Therefore, it is best to choose fertile, loose and well-permeable sandy soil for cultivation.

2. Transplanting

When Andrographis paniculata grows to about 6 cm in height and has 3-4 leaves, it can be transplanted. Before transplanting, it is best to water the seedbed first to facilitate lifting the seedlings with soil, and the survival rate will be very high. It is also necessary to choose to transplant in the evening or on a cloudy day, and the plant spacing should be about 25 cm. Water the plants immediately after planting. It is best to water it once a day. You also need to loosen the soil a little to help it grow.

3. Fertilization

1. Medical stone fertilizer method: Sprinkle a layer of medical stone particles on the soil in the flowerpot, which can not only promote the growth of flowers, but also prolong the flowering period.

2. Broken eggshell fertilizer method: Crush the eggshells and bury them in the soil of the flowerpot. This will make the flower grow luxuriantly, with bright flowers and lush leaves.

3. After the soybeans are cooked: you can dig three small holes in the flowerpot, put three to five soybeans in each hole to a depth of two to three inches, and then cover it.

4. Rice washing water: Rice washing water not only does not hurt the roots of flowers, but is also a mild compound fertilizer.

4. Pest Control

1. Damping-off disease: It will occur in the stage of 1-2 pairs of true leaves. You can treat the soil with 50% carbendazim, or irrigate the diseased area with 1000 times the solution.

2. Damping-off disease: If there are 2-3 pairs of true leaves, be sure to control the temperature, pay attention to ventilation, and strengthen the management of the seedbed.

3. Black stem disease: It usually occurs in the adult plant stage. Usually, you should pay attention to draining stagnant water in time, strengthen management, and avoid continuous cropping.

4. Disease: During the epidemic period, spray the diseased area with 50% carbendazim or 1000 times diluted carbendazim.

In addition, it is necessary to prevent and control cotton bollworm, mole crickets and viral diseases.
