Think of it as an umbrella for your flowers! Your hydrangeas will thrive under their new protective cover.
22. Avoid Overwatering Before Frost
While it’s important to keep your hydrangeas hydrated, don’t go overboard right before frost. Too much water can lead to root rot and stress the plant out.
Stick to moderate watering, and let the soil dry out a little between waterings. Hydrangeas like it balanced—just like us!

When frost threatens your potted hydrangeas, try placing a hot water bottle under the pot to keep the roots warm. It’s a simple trick that works like magic, keeping the chill away from their roots.

Being prepared means less stress and happier hydrangeas. It’s all about being ahead of the game!
26. Prune After Frost
Avoid pruning your hydrangeas before frost hits—wait until after to ensure you don’t accidentally cut off potential new buds.
Pruning too early can expose the plant to unnecessary damage. When the frost danger has passed, give your hydrangeas a trim to encourage healthy growth. Patience now means more blooms later!
