it should not be planted that close to the foundation.. perhaps the cement is leaching into the soil.. doing what.. altering pH???? also.. the first suggestion when something favors ALL GREEN over flower production ... is lack of enough sun ... and next.. too much nitro fert ... not to mention.. transplanting bulbs can set them back a lot... if they dont bloom this spring.. move them to more sun.. in fall ... ken

While looking into midge chemical cures, I found disturbing information on merit and bees... sigh. I found this info in the American rose Annual from 1918 on the treatment of midge at the time by Mr. Koch in Humboldt Park gardens in Chicago. I don't know where I'd get a load of tobacco stems, (ha), but I thought this organic treatment was interesting. "He found many of the plants affected with mildew and stem- blight, and, in 1911, rose midge had been introduced with new plants in the three principal parks. Hybrid Perpetuals and Gruss an Teplitz were found particularly susceptible to attacks of the midge. After considerable experimental work, Mr. Koch adopted mulching four inches deep with tobacco stems. It is applied after the first summer hoeing, about mid-June, and spaded under after frost in autumn. Where the mulch becomes thinned or shifted in the course of the summer, additional appUcations are made. This, he found, prevents hibernation of the pest. Last summer but few larvae and few injuries were found. For the greater security of other varieties, it was found necessary to remove Gruss an Teplitz from Douglas Park entirely in 1915." Any thoughts, my knowledgeable friends?

This happens to me whenever we have late frosts and you don't cover the plants. They are very touchy when it comes to frost. Therefore, everything will look great on the plant but no blooms. This has happened to me twice and whenever I hear of possible frost the hydrangeas get covered. Three of mine are blooming but one isn't. I think that one wasn't covered well enough.

They grow at a medium pace but if you want to divide it I think thats a good size. Doubtful that it will bloom for a few years
