Garden How-to’s

When purchasing tulip bulbs make sure that they are large, firm and heavy. Store the bulbs in a cool, dark place until planting time.

Remember that it is time to plant tulips in mid to late fall when you are raking leaves and doing other fall clean up chores . Soil temperature should be 55°F or cooler. Choose a planting location with full to part day sun, where the soil is well drained and easy to dig (never soggy). Loosen the soil to a depth of 10”.

Tulips look best when they are planted in informal groups of 12 or more bulbs. Space the bulbs approximately 3 to 4” on center and plant them 6 to 7” deep. Use a garden trowel to plant individual bulbs or remove the soil from the planting area, place the bulbs and then refill the hole.

Tulips are at their best the first spring after planting. For this reason, the bulbs are usually treated as annuals and dug out when they finish blooming. Under ideal growing conditions (sharply drained soil, cold winters, cool springs, hot, dry summers) some tulips will return to bloom again another year. The best candidates are Darwin hybrids and Species tulips. To encourage re-blooming, cut off the spent flowers as soon as they fade and allow the foliage to continue growing until it is yellow and dry.
