Hi! I haven't been on this forum yet but I thought this would be the best place to ask my question.

I know you have to leave the bulb leaves on to feed the bulbs for next year but my question is, for how long? Do you wait until they are completely brown and dried or can I take them off right away when they start to brown on the edges and tips?

I rely on my own 60 day rule: if the bulb bloomed 60 days ago I remove the old yellowing leaves. Others are sure to offer their opinions. Once the leaves yellow they quit taking up nutrients so I just put most in my compost piles.

when most of the leaves are yellow, I take them outside to the shade to totally dry out, and then to the cold (about 40-42F) till next year.

This is of course for the winter bulbs, that are dormant in summer. Plants that do not dormant and summer and have leaves all year around, stays in the ground.

For daffodils:
The bulbs make their next year's bloom after flowering, so never cut the foliage until it begins to yellow (usually late May or June).

Yes, all of these are outside planted in the ground. They are just starting to turn yellow and dry out and they are flopping all over the place. But there is still some green in there and I wondered if it was OK to take them off or if I need to wait until they are completely yellowed and dried.

you can take them out, and dry them on the sun

I never dig out my bulbs. I know some people do and then replant them in the fall but I haven't had a problem with them coming back every year. I just cut the tops off and wait for them to come back in the spring!

by digging them, storring then in the refrigerator and then planting them back you can break they dormancy earlier, and get a bloom twice a year.

Our season is too short to get a second bloom. First frost would take out the buds before they could open. I have a reblooming iris that I've only seen rebloom once. It gets a second batch of buds sometimes but they never get the chance to open before winter sets in.
