Absolutely! That will really help root production. Over-watering when the roots aren't present can result in rot. The little buggers will send out roots in search of water. Give it a shot! I'm sure you'll see results.

Another thing that may help is bottom heat... I use a small heating pad made for plants, bought at Harbor Freight, for my bulbs that are reluctant to root. I find it helps in most cases.

I had to move several after the storm, they were in full sun and not liking it. One of them I know has been there for at least 2 years. It blooms every year. Didn't have a single root on it. I planted it in another spot, it's sending up new leaves. The bulb was nice and healthy, none of the others were without roots. I'm not sure what's up with it but will just let it be.
Tally HO!

That blows my mind about the bloomer sans roots. That gives me so much hope for my Grand Cru who only has one live root :-)

They'll send out roots when the time is right and the environment is right. When I get a reluctant root-er, so to speak, I use a bit of rooting hormone powder on the basal plate, and also stick the pot on the heating pad. I find that keeping plants that are rooting out of direct sun helps, too, so they can focus on producing roots and not top growth.

Will a bulb grow if no roots at all?
