Naturalising means bulbs growing and seeding as they would in the wild; i.e. “in nature”. In some gardens this means growing bulbs in grass instead of borders.
To naturalize bulbs they need to be planted where they can remain undisturbed without the need for the foliage to be prematurely removed. Leaves need to die back for about six weeks after the flowers have faded.
Growing Bulbs in Grass
- Crocus will thrive for years if planted in grass with a dry or fast draining soil. If the lawn is lush and gets lots of high nitrogen fertilizer it will stunt the flowering process of the bulbs. You’ll get lots of foliage but no flowers.
- Plant in groups or clusters so you can mow the other area.
- You need to be patient as a bulb seedling will take 5-7 years before it has built up reserves to flower. Above all do not deadhead the flowers so they can seed a couple of months after flowering.
- Plant species bulbs rather than showy doubles.
