  1. Find a location where the soil drains well. If there are still water puddles 5-6 hours after a hard rain, scout out another site. Giant white squill do not grow well in moist soils.
  2. Giant white squill thrive in full sun or under the canopy of deciduous trees. These trees drop their leaves in the fall and don't replace them until spring. During the winter, when the trees are bare, is when squill leaves grow and need sunlight. Squill is the ideal plant to provide counter seasonal greenery in the landscape.
  3. Dig large holes and plant the bulbs so their tops are even with the soil surface. Space 18 to 24" apart to allow to the mature plants' size.
  4. After planting, water well, thoroughly soaking the area once to settle the soil around the bulb. Roots and leaves will form in the autumn. Leaves will stay green and lush until the beginning of the dormancy period in May.
  5. Foliage will yellow and die back in early summer. Feel free to remove these leaves as this will make it easier for the flower stalk to grow. Don't water your squill when they are dormant. The flower stalk will develop in August and will grow very quickly.
  6. When in bloom feel free to cut flower stems unusual bouquets. This will not hurt the plants.
  7. After blooming has finished for the season trim off the flower stalk. Leaves will sprout again in November and provide nourishment for next year's show.

Pots, Barrels, Tubs & Urns
Giant white squill develops very large roots and prefers not to be moved. For these reasons it is not recommended that these plants be grown in containers.
Note: Giant White Squill is a dry land, Mediterranean plant. It grows most successfully in locations that receive very little water.
Regarding dormancy: Most plants slip into dormancy over a period of several weeks. Giant White Squill often does so virtually overnight. One day the plant looks fine the next day it appears to have been stepped on. Not to worry. Everything about this plant is dramatic, from the size of the bulb to the way it produces flower stalks in the absence of foliage, to the height of the stalks, the number of individual flower, etc. Given this, it makes sense that the "slip" into dormancy for this unusual plant should be more like a leap. Relax. This is normal for Giant While Squill.
