How to Propagate Giant White Squills

The giant white squill (Urginea maritima) emerges from a soccer-ball-sized bulb that grows wild in the Mediterranean. The ornamental flowers bloom in the summer on a 5-foot-tall stem bare of leaves. The green foliage appears after the flowers fade in the fall. In the right environment, the giant white squill is simple to grow, demanding little of your attention. In the United States, southern California has a climate compatible with the plant's cultural needs. Plant seeds to propagate giant white squills.

Seed-starter mix
Flat with drainage holes
Spray bottle
Liquid general fertilizer
4-inch pots with drainage holes
Aerated potting mix
Spoon

Instructions

- 1
  Add seed-starter mix to a flat. Irrigate the soil until excess water drips out of the drainage holes.
- 2
  Sow the small seeds on the soil surface at the rate of one seed per square inch. Sprinkle a fine layer of seed-starter mix on them. Spray the new surface with water. Keep the soil moist throughout the germination period.
- 3
  Select a general fertilizer that contains equal percentages of nitrogen, phosphorous and potassium. Buy a liquid or water-soluble formula. Feed the squill seedlings at the rate and frequency indicated on the product label. Grow the plants in the flat through their first season.
- 4
  Transplant the seedlings to 4-inch pots filled with well-aerated potting soil, such as a peat-based mix. Wait until the plants' tops die, a sign the squills are dormant. Use a spoon to gently scoop the immature bulbs out of the flat. Plant two to three seedlings per pot. Grow them in containers for another year before moving the mature bulbs to the ground.
