I have dug up and divided a huge clump of iris bulbs which didn't flower this year. I plan to replant them, but what do I do with the bulblets? Will they develop into full sized bulbs? If so, do I leave them attached to the 'parent' or separate them? Thanks.
Yes, the bulblets will develop into full-sized bulbs over time.
It's really up to you how much time you want to invest in them; you can split them off and plant them into pots/trays, and nurse them for the next 3-4 years, or just leave them on the parent bulb and let them develop that way.
Thank you: I think I'll let their parents 'bring them up' ...
Often wise to let Mother Nature take her course.
ive got some iris bulbs that have flowered how far down the stem do i cut ,to put in a vase
You can cut as low as you like as long as you don't damage the leaves - they're the thing that the bulb needs to build up strength.
