How to Plant Bulbs
Bulbs can be loosely grouped into two categories: those that bloom in spring and those that are summer bloomers, also called tender bulbs. Spring bloomers are usually planted in fall, while summer bloomers, which include lilies and begonias, may be planted in spring. In cooler climates, these are lifted from the ground every fall and stored over the winter, to be planted again the next spring.
Bulbs like soil with good drainage, and most do best in full sun. Other than that, they are fairly carefree and forgiving of less-than-perfect conditions. Many bulbs, especially spring bloomers, are most attractive when planted in groups or naturalized in a wooded or informal cottage garden.
How to Grow Bulbs
- When. Plant your bulbs in either fall, for spring blooming flowers, or spring, for plants such as Asiatic lilies and bearded irises.
- Where. Most bulbs appreciate at least four hours of sun a day, so plant them in an area that gets good light. They should always be placed in soil that drains well to keep the bulbs from rotting.
- How. Dig a hole that is two to three times as deep as the bulb is tall. Place bulbs in the hole with the pointed end up. Cover with soil that’s been mixed with well-rotted compost or manure and water well. Cover the area with an organic mulch to conserve water.
How to Care for Bulbs
- Watering and nutrients. Bulbs need about an inch of water a week. If you are not receiving this from rain, consider a light supplemental watering.
- Pruning. After blooming, cut off flower stalks. For spring bulbs, don’t cut leaves until they have turned brown; for summer bulbs, trim any dead or wilted leaves when you find them.
- Pollination. Bulbs may be attractive to small birds and insects, especially summer bulbs like Asiatic lilies.
