Summer management method for bulbs: After the summer, some flower bulbs such as irises, tulips, and fragrant scented flowers in the spring will enter a dormant state. At this time, they must be excavated from the soil, and the residual flowers on the ground part will be cut off, leaving only the bulbs. A small amount of soil, dried it, and put it in a cloth bag a few days later, hanging in the air to prevent rodents. Although the summer season is hot and humid in most parts of China, this method does not make the bulbs rotten and moldy. Some bulbs are rich in starch and sugar. If left in the soil in the summer, some underground pests will take the opportunity to empty them, so they will not get the bulbs.
