To prepare your soil for planting Garden tulip, incorporating organic matter such as compost or well-rotted manure is essential. These amendments improve soil structure, enhance nutrient content, and increase water retention, providing a well-balanced environment for tulip bulbs. For sandy soils, adding compost helps retain moisture and nutrients, while for clay soils, compost improves drainage and reduces compaction. Using amendments in the fall allows these materials to break down over the winter, making nutrients available to the tulips in spring.
