Species such as crocus, winter aconite, snowdrop, and Scilla sibirica usually do well under trees. Also allow foliage to turn yellow before removing in late spring. There are many ways to use bulbs in the landscape. Mass plantings in solid beds, groups clustered in perennial beds or rock gardens, borders along walks or patios, and foundation plantings are all good choices. Annuals can be scheduled to follow spring bulbs.
Proper planning can provide color for most of the spring.
Plant bulbs this month so roots have time to get started. As a general rule, the depth of soil above the bulb should be about twice the diameter of the bulb. Allow adequate space for bulbs to grow, especially in naturalizing plantings. Planting details usually come with bulbs.
