I know I should have planted these bulbs in september but is it tooooo late to do this now? Over the last few years I must have planted hundreds but hardly any come up each spring. This time I've got a bag of 100 to plant. Wish me luck!
If your bulbs keep disappearing then - assuming they've not been eaten by animals - they've either rotted away or been planted too shallow. Try putting grit at the bottom of the planting hole and add some bonemeal under the bulbs.
