Oh, I completely get your excitement! Blue hydrangeas indoors sound amazing. Key things to consider: they love bright, indirect light and consistent moisture, but make sure the pot has good drainage to avoid root rot. For the blue color, you can use soil that’s specifically designed for acid-loving plants, or amend regular potting mix with peat moss. Also, a little aluminum sulfate can help maintain that vibrant blue. Just be cautious not to overdo it! Keep an eye on humidity levels-these plants love a bit more moisture in the air. Good luck, and enjoy those gorgeous blooms! 🌿💙
