Cultivation instruction

Plant Indoors: Can be started off indoors but Agapanthus are a very hardy group so can be planted direct into soils outside.

Plant outside: From Late February on wards, when the soils are starting to warm up and are not waterlogged. Prepare soils by digging in some well rotted humus matter and some grit if soils are heavy. Spread out the roots below the soil surface and plant the rhizomes so that the tip of the stem shows above the soil surface.

Protect early growth from slugs and snails and remove dead heads during the flowering season to get the best from them.  Regularly feed during the growing season with foods such as are well rotted manures, Tomato feed and bone meal will provide food for continued flowering.

Can be planted in containers, use a good quality potting compost with drainage in the bottom of the pots.

Care Tips:

It may take a year before the Agapanthus establish enough to produce flowers.

Plant as soon as possible after delivery and fan out the roots so that just the tip of the stem is showing above the soil.

Can be used for Cut Flower and companion planting with Lilies
