Step by step

  1. Buy firm, heavy bulbs from a garden center or bulb grower.
  2. Pick a sunny spot with soil that drains well; bulbs rot in soggy ground.
  3. Plant them Sep 25 – Oct 31, 6 to 8 inches deep, pointed end up, 4 to 6 inches apart.
  4. Water once after planting, then let the rain take over. Leave the leaves until they yellow after blooming.
  5. Harvest: Cut when buds show color but are still closed. After blooming, let the leaves die back on their own to feed the bulb.
