How to grow grape hyacinth (Muscari)

Grape hyacinths attract a wide range of pollinators, including bees, providing them with an early source of pollen and nectar after hibernation.

How to grow grape hyacinths

Plant grape hyacinth bulbs in moist but well-drained soil or compost in autumn, and water well. Cut back after flowering to prevent seeds developing.

Where to grow grape hyacinths

For best results grow grape hyacinths in moist but well-drained soil, in sun or shade. They work well when naturalised in a lawn but also in container displays, such as a window box.

How to plant grape hyacinths

Plant grape hyacinth bulbs in autumn, in small clusters. Dig a small trench 10cm deep and toss in a handful of the tiny bulbs. The same principles apply when planting in a pot, but you can get away with planting the bulbs closer together as the display won't be permanent.

How to care for grape hyacinths

Grape hyacinths don’t need VIP treatment and will spread quite happily once established. Cut back spent flowers to prevent seeds developing. Lifting and dividing established clumps can help control their spread while increasing flowering potential.

How to propagate grape hyacinths

Propagate grape hyacinths by division when plants are dormant in summer. Dig up a congested clump and split apart into smaller clusters and replant. You can also save seed and sow this in spring, but it's much quicker and effective to propagate by division.

Growing grape hyacinths: problem solving

Grape hyacinths are not affected by any pest and diseases. However they do have a tendency to spread and can be invasive. Grape hyacinths can spread by seed as well as underground, via bulb offsets. Deadhead spent blooms to stop seeds developing, and keep an eye on established clumps – if they look like they're spreading too well, dig them up and replant the bulbs in a pot. Ensure you have gathered all the bulbs in the soil to avoid having to dig them up again.
