Hydrangeas prefer full sun to partial shade as well as moist but well-drained soil.
Regarding feeding, we recommend using Bio Tone or Bone Meal when planting to help establish the root system and then use a good all around fertilizer from then on. Also, depending on which fertilizer you use, you can change the color of the blooms on many varieties of Hydrangeas. Acid soil will make your blooms more blue while a non acidic soil will result in pink flowers. You can use Aluminum or Iron Sulfate to add acidity to your soil and lime will neurtralize the acidity to turn your flowers pink. Keep in mind that this is not something that happens overnite and will take time to get into the soil and the plant and effect the color of the bloom.
Why isn’t my Hydrangea flowering?
There are a few reasons why hydrangeas may not flower. The most common is frost damage. Another common reason is late pruning. The easiest first thing to check if your hydrangea is not blooming is where it is planted. Be sure that the area is getting enough sunlight and if it is planted where it will get high exposure to wind and other weather elements, it may be best to find a more protected location.
Incorrect pruning is the #1 reason that hydrangeas do not bloom. Panicle hydrangeas should be after winter has started or in very early spring. Big Leaf varieties should be pruned right after flowering.
