Answer: There are three common reasons for hydrangeas not blooming; winter kill (or poor pruning practices); immaturity; lack of adequate sunshine. Hydrangeas bloom on new shoots which develop on old wood. If the canes regularly die down to ground level each winter, there will be no old wood and therefore the plant will not bloom. If the old wood does not die down to the ground each year and your plant develops new shoots from old wood, it should bloom, providing it is getting some sunshine during the day. You may need to move your plant to a site that receives at least 4 hours of morning sunshine. Finally, your plant may be just too young to bloom, which it will outgrow in a year or two. Hope this sheds some light on the subject!
