Gardening Questions And Answers
Planting potted hyacinths outdoors requires some pre-planning. Hyacinth bulbs can thrive in any well-draining garden bed that receives full, all-day sun and has a soil pH between 6.0 and 7.0. Amend the site with a 1-inch layer of compost and 1 pound of a 5-10-10 fertilizer per 50 square feet before planting.
Hyacinth bulbs are normally cold-hardy enough to tolerate Chicago winters, but they do need to be fertilized annually to produce those large masses of florets year after year. Since their heady sweet fragrance is one of their major attributes, plant them close to a walkway you use, in full sun with excellent drainage.
