Q.Planted 3 Monrovia Hydrangeas Last Year. Although The Plant Is Leafy Green, There Are No B Looms On Any Of Them And This Is Late
June. What is wrong? Any suggestioins.
It depends on the type and the cultivar. Big Leaf Hydrangeas are one type of hydrangea and they come in two flavors. Flavor #1 only blooms once in spring 2023 from buds developed in July-August inside the ends of the stems. If all the stems got killed by winter or frosts, it will not bloom again until spring 2024. Flavor #2 has two flushes of blooms, one in spring 2023 from buds developed in July-August inside the ends of the stems and a second flush from the brand new spring 2023 stems. Those can fail to bloom in spring if last year’s stems do not survive winter or if the stems get pruned before the end of June in the northern half of the US. But those usually are successful blooming in late summer if the new spring 2023 stems do not get pruned and are able to get tall enough quickly enough to develop flower buds and open them in the summer or so. Some Big Leaf Hydrangeas were affected by the December 22 arctic blast that killed stems as far south as Texas and Georgia. Smooth Hydrangeas should be blooming now or should be about to start opening flower buds soon. Panicle hydrangeas bloom after the smooth hydrangeas so it may be too early for some; however, you may be able to see some blooms in early panicle varieties or see some buds in the south and some Atlantic states. Limelight for example, is a mid-season bloomer (around July usually in the northern half of the US) and Tardiva is a late season bloomer.
