3. Planting of pilose dentate water lilies

The flower pots of pilose dentate water lilies should be planted as far as possible, and those with leaves that open outward will be better than those with inward leaves. The leaves grow well, and the wider the pot mouth, the larger the flower (it has little to do with the size of the pot bottom). The depth of the flower pot will affect the flowering interval, and the deeper the interval, the longer the interval. Try to choose soil with higher viscosity, such as: clay, Yangmingshan soil. Then put a little long-acting fertilizer or root fertilizer on the bottom of the pot (too much will rot the roots), put about 1/4~1/3 of the soil in the flower pot, press it tightly, and then bury the bulbs in the soil with the buds facing up. Buried deep, the flowering interval will be longer but larger, and shallow buried, the interval will be shorter and smaller. After planting, move to a well-lit place, fill up the water, and wait for the long leaves to bloom (the leaves can be trimmed if there are too many).
