What to do, and when
The usual months for a UK garden. Your own plan gives the week.
Planting
Plant crocus corms September to November, 7 to 12cm deep, 9cm apart. Moderate source: RHS.
Lift and divide the crocus
Every 2 to 3 years, not every year.
Usually August. Moderate source: RHS.
Net the crocus
Net grassy areas, or cover pots with wire mesh, so squirrels can’t dig up new bulbs.
Usually September to November. Moderate source: Gardeners’ World.
What the source words mean
Moderate: another trusted UK source, or the RHS on its group.
What not to do
Don’t take the leaves off while they’re green
Let crocus leaves die back on their own.
Moderate source: RHS.
