Allium Ostara is a variety that keeps it’s foliage better than most during flowering. Plant bulbs approx four times deeper than the diameter of the bulbs.  Allium Ostara is superb for bees and butterflies and will naturalise very well in most soils that are well drained. Feed with bone meal or similar during the leaf and flowering stage to ensure future good growth and performance. Alliums perform very well with early flowering perennials.

Cultivation Instructions

Alliums perform very well with early flowering perennials and in addition they are also popular with bees and butterflies. They naturalise very well in most well drained soils.

Cultivate soils to a depth of 20cms and plant bulbs with the pointy bit facing upwards.

Feed bulbs with bone meal or similar during the flowering period to ensure they remain health for years to come. Plant in areas that are not exposed to the worst of the elements and in soils that have not been freshly manured. Regularly feed during the growing season with foods such as well rotted manures, Tomato feed and bone meal.

Care tips:

Ensure that alliums are well fed during the growing season.  To ensure they perform year after year, mulch borders with well rotted manure or compost over the winter.
