The Q&A Archives: Container Size For Nikko Blue?

Question: I have a container garden and would like to add two Blue Nikko Hydrangeas which are now in 4" pots from the nursery. What size container size would be opt for one or for two in one container? Thanks so much.

Answer: Your hydrangeas will eventually grow 4'-6' tall with an equal spread. Knowing this, you'll want to plan ahead and move the shrubs into larger and larger containers as they grow, to accommodate their growing root systems. Since they're just babies now, you can replant into slightly larger pots and next spring put them into 1-gallon pots. As they mature you'll transplant into 10-15 gallon pots as required. Once they reach full size you'll need only to replace the potting soil every 2-3 years to keep them happy.
