I have an 18″ x 18″ pot and would like to plant either a 1 or 2 gallon hydrangea bloom. I live in NYC and have a large terrace. Am I better off to get the 1 gallon size and keep it trimmed to fit in the pot as it grows – and replant it to a larger pot – or divide to fit in two pots later on?
You will want to move the hydrangea into larger pots as it grows. Trimming it back will reduce the number of blooms. Hydrangeas are also not plants that can be divided, so you’ll want to choose a variety that stays genetically compact for your patio. I’d suggest Summer Crush® or BloomStruck® hydrangea. Happy planting!
