Nothing lifts the spirit in Spring like the arrival of daffodils, tulips, crocuses, starflowers, bluebells, hyacinths and alliums. And bulbs are so easy.
Ideal temperatures to plant are between 50 and 60 degrees, but bulbs will do fine within a range of 38 to 70 degrees. The planting site should get several hours of sunshine, but they will do well beneath trees because bulbs will bloom before the tree has leaves. The soil needs to drain well; if planted where water collects, the bulbs will likely rot. The drainage of heavy clay soils can be improved by adding compost.
