Pepper seedlings are generally planted from March to April. Use scissors to cut off the rotten root, diseased root and longer root of the dug pepper seedlings. Then use a thousand times diluted potassium permanganate solution and soak it for 20 minutes before planting. When planting, first dig a hole about 20cm in the ground, put the pepper seedlings in, and then fill the soil. Just pour the water one last time.
