Hyacinthus orientalis cultivars

I disagree in that forcing bulbs does affect the following years growth.
Hyacinths are usually tough enough to overcome this if the bulbs are fed
and allowed a long growing season. Forcing tends to cause the bulbs to
divide into smaller bulbs after flowering. I believe that it also boosts
the flowering at the expense of resources in the bulb which would otherwise
go into boosting leaf growth.

For forced bulbs I expect a year of good flowering followed by a year of
recuperation, the third year should see the plant growing naturally.
