I have been reading and reading, studying, and asking the experts about the correct time and way to prune hydrangeas! There is so much to know, I think I should have gotten a degree in ornamental horticulture. So many things to consider. One of the big considerations is the variety of hydrangea.
Today I am biting the bullet, taking pruning shears in hand and deadheading the mop head hydrangea. If I have done my homework correctly, mop heads should be pruned (deadheaded) before new buds form. Most experts say "August." This is nail biting--the hydrangeas were beautiful this year and I want them to be ever better Next Year.
Miss Oak Leaf is a different variety of hydrangea. I do not deadhead Miss Oak Leaf. The blooms and leaves turn a beautiful crimson and cinnamon color and the birds feed off the blooms. Oh, Miss Oak Leaf, don't disappoint me.
