Cultivation instruction

Plant Indoors: They are at their best when grown outside in containers.

Plant outside: They prefer a light well-drained soil. In heavy soils, just add grit and sand to lighten it up. Cultivate soils to a depth of 20cms and add some well rotted manure or granular fertiliser to the soil when cultivating. Plant them 8cms below the soil surface. Cover with soil and firm around bulbs to keep them in place. Leave to establish for a few years and protect from winter frosts by covering them in a couple of inches of mulch over winter. Can be left to naturalise for a number of years, regularly feed during the growing season with foods such as well rotted manures, Tomato feed and liquid seaweed for continued flowering.

Care Tips:

For the best results ensure soils do not dry out in the first year.

They can be left undisturbed for a number of years so that they can naturalise.

Plant with summer flowering lilies and or Dahlias for a mass of colour in the summer.
