Care and Winter Protection

During the Summer

There is no doubt that the agapanthus is happiest outside in the fresh air in a sunny and sheltered spot, be it in the garden, on a terrace or on a balcony.

Generous watering and regular feeding with fertilizer are desirable. Be careful not to let the soil get dry.

Good drainage is a must - agapanthus likes being watered well, but loathes 'wet feet'!

The wet summer in 2000 has caused the roots to rot in my containers. Where the plants were only slightly damaged, they recovered and started growing new roots. Others had been damaged to such an extent that I had to remove the affected roots in order to avoid further rotting.

The yellow tips on the leaves which indicate waterlogged conditions and root damage had appeared so late on some plants that it was impossible to save them - they didn't survive.

During Winter

Deciduous agapanthus may be overwintered in the darkness of a cellar or a garage at 5 degrees celsius. Watering is not necessary. (There is the danger of waterlogging the roots).

In warmer climates, e.g. where vines are grown, agapanthus can be left in the garden bed, provided it has been mulched well to avoid any frost damage.

If you are looking for hardy agapanthus species, choose those which have proven hardy in your region (according to the books).

I know several people in Berlin and the 'Erzgebirge' who have left their agapanthus with a cover of mulch out in their gardens. The plants have been thriving for many years (6 - 19) and have never suffered any frost damage.

Evergreen agapanthus have to be overwintered in a cool, light place. Entrances, unheated hallways, landings without draughts or a cold greenhouse will do. A little water from time to time is necessary, as the plant loses moisture by evaporation.
