Tulips are a welcome addition to any spring landscape. The Dutch grow over 3 billion tulips annually in a vast array of colors. Depending upon the variety, tulips can be early blooming (early April) through late-blooming (late May). Mixed with other bulbs in a border, one can achieve an early show of color from mid-March through late May. Tulips should be planted in late September through mid-October in well-drained, fertile soil. Often, bone meal is added for additional nutrients. It is important to wait to cut the foliage back in late spring until the leaves have died back at least 2/3 as they provide the needed energy for the following years flowering.
