Ithuriel's Spear problems — and how to fix them
Ithuriel's Spear (Triteleia laxa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Summer rot from overwatering
The most common failure. Corms must be kept dry during summer dormancy. In rainy summer climates, lift corms in early summer and store dry until autumn.
Floppy stems
Caused by insufficient sun or overly rich, fertile soil. Plant in lean, well-drained soil in full sun; stake only in very exposed sites.
Non-flowering
Plant corms 8-10 cm deep in autumn for best results. Corms planted too shallow or in shade often fail to bloom.
Naturalisation failure in heavy soil
Will not self-seed or establish in clay-dominated soils. Ensure free-draining conditions for reliable naturalisation.
Vole and gopher damage
Corms are attractive to rodents in garden settings. Plant in mesh cages or apply physical barriers at planting time.
