digging up Cannas in August
We have just sold our home and want to take some of our cannas with us to our new home. We live in the low country of South Carolina. We are only moving 10 miles closer to the coast on Hilton Head Island. I need to dig the cannas by the 22nd of August. Should I pot them and plant them in our new garden soon or should I leave them in a pot for awhile?
If it's really hot, I would put off planting until it has cooled some, though they can be grown and cared for in a container much the same as those in the ground, though they will require more frequent watering in a container. If you want to transplant them directly to your garden, do so on a cloudy day and make sure they receive plenty of water. They may not look great for awhile as they acclimate to their new surroundings but should eventually bounce back. In your zone, digging and storing over winter isn't necessary, so they should come back just fine. If you want to dig and keep over winter, then leaving them in a pot for now will be fine.
