    Now is the perfect time to prune oakleaf hydrangea, assuming yours is done flowering. After flowering, prune back each branch about halfway. It should still have time to produce new growth later this fall that will allow it to bloom next summer. Or, if you prefer, you can cut it all the way to the ground. In this case it will not bloom next year but should the year after.

    Some hydrangeas vary the size of their flowers based on how they were pruned the year before or based on conditions. See this article to determine how to prune your hydrangea for optimum flowering:

    I really need some pictures to help me out. Did you, by chance, plant it near a walnut tree? Walnuts emit a chemical from the roots called juglone, that kill off other plants in the area. This is unbelievably common... Any other information would be really helpful to me. Thank you

    These will, more than likely, produce white flowers, unless you use chemicals to turn the flower color. Here is an article to explain: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/change-hydrangea-color.htm

    Now, the reason it is not flowering, is more than likely that it needs some fertilizer high in potassium, and phosphorus.

    This appears to be either fungal or bacterial. I have a method that is all natural and safe for all plants. If you do not have, or can't get, all the ingredients, then it is ok. This is a very overbearing Pesticide/fungicide, and even though is safe for use at any time, and whenever you would like, it is still more than needs to be done. I would highly recommend not substituting the Dolomitic lime or wettable sulfur, as these are first defense. The recipe is as follows: Common Answers
    First, you will want to prime the ground with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.

    I recommend doing this in the fall, after the flowers have fallen off. Just simply cut them right below the old flower.
