How to Start It
★ Recommended for beginners
Plant bulbs in fall, about 6 weeks before your first fall frost, while the soil is still easy to dig. Set each bulb pointy end up, about 12 cm deep and 10 cm apart, in a sunny spot with soil that drains well. Water once after planting, then let winter do the work: shoots come up in early spring. Wear gloves, since the bulbs can make skin itch.
Hyacinths are famous for their strong, sweet scent: a few bulbs can perfume a whole balcony or room. They come back every spring, but after the first year the flower spikes get smaller and looser, which looks more natural. You can also buy prepared (pre-chilled) bulbs in fall to bloom indoors in winter, in a pot or a special hyacinth glass of water.
When To Start
Hyacinth likes cool weather. Sow it in early spring, as soon as the ground can be worked.

Plant hyacinth bulbs 12 cm deep, with gloves on
40 days before your first frost· every year
Cut hyacinths for the vase, let the leaves die back
1 week after your last frost· every year· optional
Water your new hyacinth plants well while they settle in. Deep and slow is best.
About 1 days after you plant it
Your hyacinth bulbs are growing roots underground. Shoots often wait until spring, so not yet is normal.
About 30 days after you plant it
Still resting is fine. A layer of leaves or straw over the bed helps protect your hyacinths from hard cold.

Planting & Sprouting
Growing Tips
- 1Plant hyacinths where they get full sun or light shade in spring.
- 2Soil that drains well matters most, since bulbs rot in wet ground, so mix in compost before planting.
- 3Water after planting in fall, and again in spring only if it is dry.
- 4Spread a layer of compost or worm castings over the spot each fall to feed next year's flowers.
- 5Let the leaves yellow and die back on their own before you cut them, since they feed the bulb for next spring.
- 6All parts, especially the bulbs, are toxic to people, cats and dogs if eaten, so plant them where pets will not dig.

Harvesting
When to Pick
Fragrant spikes in spring; flowers loosen and shrink in later years
How to Harvest
- 1For the vase, cut a spike when the lowest few flowers have opened, and it will keep opening indoors.
- 2In the garden, snip off the flower spike once it fades, but leave the leaves.
- 3Cut the leaves off only once they have turned yellow, usually 6 weeks or more after flowering.
- 4After indoor bulbs finish, plant them in the garden: they will not bloom indoors again, but they can flower outside in future springs.
- 5Wear gloves whenever you handle the bulbs.
