When Should I Plant Spring Bulbs?

Spring planted/summer flowering bulbs and tubers can be planted in the spring when you are certain the ground will no longer freeze in your area.  Most spring-flowering bulbs should be planted 6 to 8 weeks before the soil begins to freeze. In growing zones 4-5, the ideal planting time is mid to late October. Gardeners in zones 6-8 should wait until November. In warmer areas (zones 9-10), most spring-blooming bulbs must be chilled before they are planted.

Prepare the Soil

Break up any clumps of dirt, remove rocks and weeds, and improve drainage as well as quality by mixing in organic matter such as compost or peat moss. The easiest way to do this is to dig one large hole instead of several individual ones. Then mix in all at once.

Planting Instructions

Check the product packaging for specific planting instructions for your type of bulb. If unsure, dig a hole that’s two to three times deeper than the bulb’s height. For example, plant a 1-inch-high bulb about 3 inches deep. Many garden tools designed for this type of planting will mostly have depth markers. 

Plant bulbs with the pointy side up and the roots down. Add some compost, organic matter or slow-releasing fertilizer. Cover with soil and water well so the soil above the bulb settles.
