Heavenly Blue morning glories will grow a taproot down to 3 feet deep in the soil. The pot does not have to be quite that tall, but too short and it could stunt the plant’s growth. Whatever you decide to do, pick either in-ground or pot, but don’t do both. Morning glories have delicate root systems that can snap easily when transplanted.
Hi Susan!

We hope this helps!
