I found a small hydrangea plant at a nursery. I brought it home… unsure if it would survive.
I picked a pot with good drainage. Hydrangeas hate wet roots! I added loose, rich soil.
Hydrangeas love morning sun and afternoon shade I placed mine near an east-facing window.
They get thirsty... I water when the top soil feels dry. But I never let the pot stay soggy.
Soil pH changes flower color! Acidic = Blue Alkaline = Pink
After flowering, I cut old blooms and weak stems. That helps new buds grow next season.
