About Agapanthus
Fleshy, rope-like roots from a short rhizome. Evergreen types are less hardy than deciduous types.
Depth and spacing
Typical range: 5 cm deep and 30-45 cm apart. A general rule is to plant at two to three times the height of the rhizome; check the label for your variety. The drawing is to scale for 5 cm deep and 37.5 cm apart (the size of the organ is illustrative); try your own measurements.
When to plant
Plant in spring. Plant: 4 weeks before up to your last spring frost. These are rules of thumb for the northern hemisphere. Enter your frost dates for real dates.
Dividing and propagating
Divide congested clumps in spring, using a knife or two forks; it flowers best slightly pot-bound.
Lifting and storing
Not stored. Protect with a thick mulch or keep potted plants frost-free.
