I have 2 Hydrangea Macrophylla in pots. I used them in my wedding and want to save them. Should I plant them now or leave them in the pot for winter? Thanks for any advice.
Possibly. You can plant them now that temperatures are starting to cool down. Remember to maintain the soil moist and mulch with at least 3-4" of any type of acidic soil.
You did not mention the name of the variety so I cautioned just in case your variety cannot handle your Zone 7 winters. If it cannot be planted in your zone then I suggest you keep it in a pot outside during the growing season. Then bring it inside during winter (as soon as the temperatures go below freezing and the plant becomes dormant). Place it in a garage but remember to water it (less than usual but still some) while in the garage. Potting soil can dry easily.
