Good catch. Dcamp1017, you said the shrub was planted in a "spot" and I read "pot" instead. Ha! Sorry about that! Concentrate on these possible causes for the lack of blooms:
make sure that this variety is hardy in your zone; if not you will need to winter protect it. Do you prune this shrub? If it is a hydrangea variety that blooms on old wood, do not prune on or after July; instead, prune after blooming but before July. Try to maintain the soil moist as evenly as possible. Dry cycles can cause the plant to abort flower buds. Provide water during winter (but not as often; maybe weekly or every two weeks). Allow it to get at least 2-3 hours of sun. Add mulch so you do not have to water too often this time of the year. Fertilize the soil only once, in June, using either aged manure, compost or cottonseed meal. You can also use a general purpose, slow-release fertilizer with a NPK Ratio of around 10-10-10. If you transplant it, do it when the shrub has gone dormant in mid-late Fall or Winter.
