|I have 2 Hydrangea bushes and it keeps growing bigger and bigger, but never buds any flowers??
Is there something I can give it?
Also, I have a rose bush that I would like to move...when is the best time to move and replant where?
|The most common reasons for non-blooming hydrangeas are 1) A late spring freeze can ruin the developing bloom buds. The freeze may be light and even go unnoticed until one realizes that the blooms are not forming. Or it may kill all the emerging leaves, too. Most flower buds develop on the old stems. Once these stems are damaged in a late freeze, new flowers will not appear until the following year and only then if it is a milder spring. (This is the rule for the vast majority of mopheads [macrophyllas] but there are exceptional hydrangeas such as Endless Summer that will bloom despite this damage) 2) Improper pruning. Most hydrangea types bloom on OLD WOOD. (Stems are called "old wood" if they have been on the hydrangea since the summer before the current one.) This means that flowers are formed on the stems of hydrangeas around August, September or October for the following spring. If those stems are removed (pruned) in the fall, winter, or spring, the bloom buds will be removed, and there can be little or no bloom that year. 3) Wrong Zone. Big Leaf hydrangeas bloom on old wood. If your plants consistently freeze down to ground level each year, they may never produce flowers. You may want to replace them with a type that blooms on both old and new wood. Endless Summer is one such hydrangea and grows wonderfully well in your gardening zone. Hope this information helps you determine just why your hydrangeas are not blooming!
I'd move the rose bush while it is dormant - late winter or early spring before new growth begins. Set it in a sunny spot (8 hours or more of direct sunshine). Good luck with the move!
