I planted some Burpee hydrangeas (3 white and 3 Nikko blue) in the spring of 1998. I got a few blossoms on two white and two blue the first and second summers and nothing on 1 white and one blue last summer. What should I do to ensure full blooming this year?

I'm not sure why your hydrangeas are not blooming, but here are some suggestions. These plants also do best in a location with rich, moist yet well drained soil in full to partial sun. If any of these are lacking they may not bloom well. Most hydrangeas bloom on old wood rather than the current year's growth, so it is important not to prune them except for immediately after they bloom. Since they bloom on old wood they are also susceptible to winter damage. If the winter is a rough one and much of the wood is damaged, then they will not bloom well, if at all. If you think winter damage is the problem, you might try providing them with a windbreak.
