Plant Bulbs

Some indoor and outdoor plants are grown from bulbs. Plant Bulbs, swollen underground stems with scaleSoft Brown Scale plant pests are  the most common scale that attack indoor houseplants, especially ficus tress, various ivy varieties, spider plants, ferns, aralia, and schefflera. The scale plant pests appear as small, bumpy, brown spots that may appear to move. As the scale plant pest sucks on the sap of the plant, it secretes a sticky substance called "honeydew." The honeydew attracts black mildew. Because of the shell-like exterior, sprays are only partially effective against scale. Wipe off the lines of brown oval bumps with your finger, a cloth, or a child’s toothbrush then spray the plant with Neem Oil or a houseplant insecticide.

Bulbs should be planted deep enough in the soil so that they are totally covered. How deep you plant the bulb, depends upon the plant variety. There are true bulbs and there are rhizomes, corms, and tubers that are sometimes included as types of bulbs. Bulb plants that keep their leaves all year are used as houseplants. Bulb plants that lose their leaves after they flower and become dormant are usually used as outdoor plants.

Certain environmental conditions, such as the change in temperature from winter to spring, encourage bulb plants to produce flowers. Once the plant has finished flowering and is only a green leafy plant, the plant rests for a few months. During this time, the bulb absorbs and stores nutrients from the soil to help the plant flower again the following year.

Some indoor plants that grow from bulbs are: amaryllis, calla lily, caladium (tubers), False Shamrock plant (Oxalis triangularis), begonia (tubers), and cyclamen (corms), cyclamen (tubers).
