Planting Instructions: Plant in the fall when the soil has cooled up until the soil freezes. If you live in a warmer part of the country, be sure to plant your tulips by late November. Choose a site with well-draining soil, in full sun to partial shade. 1. Dig a hole 3-4 inches deep or two times the height of the bulb. 2. Set the bulbs firmly in place, with the pointed ends facing upward. 3. Cover the bulbs with soil and water thoroughly. Grow in informal groupings of 5 or more bulbs. In the spring, remove old flowers leaving as much stem and foliage as possible until they die down. To force your tulips indoors, plant bulbs in a container with soil and cool at 40° Fahrenheit for 15 weeks.
