What should be noted when planting Isodon serra?

Among the people it is called "tu huanglian" and can be used to treat jaundice in children and acute enteritis. Applied externally, it can promote blood circulation and remove blood stasis, and its medicinal value is extremely high. At present, it is also cultivated artificially, but how can high yields be achieved when planting it? Let us take a look at the planting precautions for Isodon serra.
1. Selection of the planting site
Isodon serra is originally a wild herbal medicine. Only after its effects were discovered by people was it widely applied and cultivated, so its adaptability to the environment and vitality are strong, and it is relatively common in the fields. However, due to uncontrolled harvesting and the destruction of its growing environment, its resources have declined sharply. Isodon serra likes humid areas with sunlight. When planting, try to choose a sunny site close to a water source. After choosing the planting site, clear the weeds thoroughly. To avoid soil compaction, after weeding, deep plow once more, harrow finely and level, then apply base fertilizer.
2. Planting density
Isodon serra is a herbal medicine. It has strong vitality, and in the later stage of growth it will spread to the surrounding area. Old branches will take root as soon as they touch the soil, then grow into new plants, so this point should be noted when planting. The planting density must be controlled well. On the premise of maintaining the quality and yield of Isodon serra, plant at a reasonable density. Generally, the row spacing for transplanting is 20×25 cm, and planting can be done at this distance. First dig out the seedlings with soil, then dig holes and set them in place, cover with a layer of soil, firm it, water, and cover with a layer of rice straw.
3. Loosening the soil and weeding
After transplanting, water 1-2 times a day, and at the same time use straw or similar materials to keep warm and retain moisture, avoiding soil compaction and water evaporation. Also loosen the soil and weed in time. Loosening the soil can prevent soil compaction, increase soil permeability, and promote root growth. Weeds will affect the growth of the plants and should be pulled out in time.
4. Fertilizer and water management
For better growth of the plants, timely topdressing is necessary. Generally, 10 days after transplanting and survival, new roots will grow, or old roots will take root. At this time, topdress in time to promote its growth, but the amount of fertilizer should also be noted. Generally, apply a thin fertilizer once every half month, and carry it out together with watering, so that the fertilizer nutrients begin to dissolve, speeding up the plants' absorption and improving fertilizer use efficiency.
