Sure, but it might cut production down next year. Anytime you interrupt habits one pays.

Thank you. I'll check out the link!

Not a problem! The bulbs fields of the Skagit Valley here in WA are a huge source of cut flowers for the retail trade. And since the bulbs are also harvested and sold both here in this country and exported to Europe, I doubt there is much concern regarding the continuing viability of the bulbs. That's what they're making the money from - not the flowers :-)) It is actually better for the bulb to remove the flowers than to allow them to remain and develop seeds. If you give the bulbs proper growing conditions and care and allow the foliage to remain and ripen properly, you'll be fine. When cutting lilies for the flowers, be sure not take more than 1/3 of the stem and leave the rest to recharge the bulbs.

Gardengal is right; the bulbs will actually be stronger next year if you remove the flowers. The bulb growers in Holland mow down their flowers so the plants can devote all their energy to bulb development & next year's flowers. Just don't cut the foliage down until it turns brown.

I always cut my bulb flowers. Like the others have said, it actually is much better for the bulb. Once you cut the flower, the bulb can concentrate on storing energy for next year,instead of wasting energy on the flower. My blooms get better every year and I fill my house with vases full of them.

i just want to thank my friend maria2015 for posting this message for me. All the replies been very helpful.
