The good news is that hydrangeas are easy to move anytime as long as the ground is not frozen. The traditional Hydrangea macropylla with the mophead blooms prefers morning sun and afternoon shade. The East side of a house is great.  The sticks that rooted for you will become shrubs very quickly. You can transplant the rooted cuttings into the garden and you will have a blooming shrub in a few years. They look lifeless in the winter as they are dormant. To encourage them you can leave in the pot and add a slow release plant food this spring such as Osmocote. Hydrangeas love moist soil but they can drown if you keep the soil too wet. Moving some cuttings into the  ground and letting just one stay in the pot will work well to encourage more growth as they won't be so crowded. Keep growing, Marianne Binetti
