Hyacinth: Sowing, planting and harvest calendar
When and how do you plant hyacinth bulbs?
Plant garden hyacinth bulbs, Hyacinthus orientalis, in autumn for spring flowers. Adjust timing to climate and work in unfrozen ground that does not remain waterlogged. Bulbs specially prepared for early indoor flowering follow a different programme, so distinguish that treatment from ordinary garden planting.
Choose a sunny or lightly shaded position with free-draining soil. Select firm bulbs without soft or rotten areas. Wear gloves if handling them irritates your skin. Set pointed ends upwards at around 10 cm deep, following the batch guidance and your soil conditions. Allow about 8–10 cm between bulbs.
Cover and water to settle soil against them without leaving a pocket of standing water. For an outdoor pot, use drainage holes and free-draining compost. Make sure surplus water escapes rather than staying in a saucer. A pot exposed to severe winter needs more protection than bulbs planted in the ground.
Mark the spot so you do not dig into bulbs before shoots appear. Their increase through small offsets is slow. If moving a clump later, wait until foliage has completed its cycle instead of pulling out green leaves.

How to care for this plant

Remove faded flowers
Once the entire hyacinth flower spike has faded, cut only the flower stalk at its base without harming the leaves. Keep green foliage until it yellows naturally so the bulb can rebuild its reserves. For a forced hyacinth, follow its actual flowering rather than the garden season.
