Answer: Plant summer-flowering bulbs after danger of spring frost. In your growing region, the first full weekend in May is a safe bet.
Where a large number of bulbs are to be planted, prepare the beds to a depth of 9 to 12 inches. Uniform bed preparation permits a uniform planting depth that helps insure uniform flowering. Plant in well-drained soils.
Bulbs may be planted individually by using a bulb planter to remove a core of soil and placing the bulb in the hole, or use a trowel to open a hole within the soil. Pull the trowel toward you to open the hole for placement of the bulb.
Plant bulbs two and one-half times deeper than their diameters. To extend the blooming period, plant bulbs at different depths and different locations. This an excellent way to vary the time of bloom up to 2 weeks.
Best wishes with your flower garden!
