General Bulb Planting Tips

Bulbs ideally suited to pot growth include Snowdrops, crocus, Iris danfordiae and reticulata, grape hyacinths, scillas, puschkinias, chionodoxas, anemones, hyacinths, narcissus (particularly the small-cupped and species varieties) and tulips (particularly the fosteriana varities (such as ‘Orange Emperor’ and ‘Purissima’), Single Earlies (such as ‘Prinses Irene’, ‘Couleur Cardinal’ and ‘Cairo’), Double Earlies and Triumph tulips (such as ‘Havran’)

Drainage is key with bulbs, so all pots and containers need one of more holes in the bottom. These holes then need to be covered with crocks – pottery shards or pebbles – to keep the holes from being clogged with earth.

In pots, you can plant your bulbs closer than you do in the garden. Even so, they shouldn’t touch each other or the sides of the pot.

If planting just one layer of bulbs, plant at the same depth as you would in the garden – at a depth of twice their height at least (a minimum of 3 inches).

Water on planting, and regularly in the first weeks when their roots are forming. Don’t let the compost dry out.

Pots planted with spring-flowering bulbs can tolerate a certain amount of freezing weather, but will need some protection in moderate to severe periods of frost. Cover them with branches or circle the pots with bubble wrap to insulate.
