A lily is an example of a plant that propagates by producing new bulbs or corms. These bulbs or corms are also responsible for food storage. Bulbs contain many parts but are mostly composed of leaf scales. Lily bulbs are loosely scaled and need to be handled with care since they do not have a tough outer covering. Lily bulbs are commonly planted in the fall. Since lilies are very susceptible to bulb rot, proper soil preparation and watering are necessary in order to prevent this.
Planting and Watering Lilies
Lily bulbs should be planted as deep as two to three times their height. They should not be planted more deeply as this increases the chances of bulb rot. Lilies need moist, rich and cool soil for optimal growth. The soil needs to have good drainage if the lilies are to grow well at all.
Lily bulbs need to be planted as soon as they are bought and should not be bruised or allowed to dry. They should be watered well immediately after planting, then watered as needed to keep the soil moist. At the first hint of growth they should be heavily watered only about once in a week. Overwatering must be avoided as this can cause not only bulb rot but also fungal diseases. Bacterial soft rot and fusarium bulb rot are the two common problems associated with overwatering lily bulbs or planting them in soils with poor drainage.
