Chances are they will be just fine. It probably would have been better to have dug them earlier though before they had started to root again, but you know that now.

I dug some daffs the other day, and was surprised to see they had broken dormancy and had roots. I now know I should have dug them quite a while ago. I understood a daff pro( IMHO) say the other day, that some daffs will start to grow again in late July. I know one should not plant bulbs too early and a combination of warm soil and moisture could make a bulb rot before it started to root.
While I have in the past always advocated digging them when one has the time after them dying back (say June) and then replanting them immediately, I have stopped and rethought this. I can see where that would 'not' be a good idea now due to what my daff friend said. They should not be planted back until the fall when soil temps have cooled a good bit.

I'm thinking that the instruction to divide Hyacinths in autumn probably relates to bulbs which have been held in cool storage out of the ground over summer. At that point the daughter bulbs are often loose beside the root plate and separate easily. Then you can plant out the biggest bulbs for flowering and the smaller ones into a separate bed for growing on.

You can do this much earlier on, too. When the leaves die back - and the roots, lift the bulbs, put the large ones into storage and immediately plant the smalls so they don't dehydrate over summer. Temperatures under ground are usually much cooler than above over summer, particularly at the usual depth for Hyacinth planting.

I agree with your bulb pro, Sue. The first-up Narcissus are already putting out roots in my January, your July, when they are left in the ground. The later 'trumpet' blooms seem to start sprouting roots quite a lot later (March).

With the divided Hyacinths - they'll probably flower but it would be worth cossetting them with some good compost afterwards while they're still in full leaf - unless they've been replanted into a well-fed area now.
