Thanks Fiat for the info.
Move the plant now outdoors, it can take full sun. As you do it, give it a thorough watering. You need to adjust watering when seasons change. In our very dry 9b location, it can be watered every two weeks, drenching the root zone very well once it is outdoors.
That's okay if you cannot see the base, it really grows so close to the soil.
Eventually the plant will acclimate and get more vigor. Usually I get my blooms at this time of the year too, afterwards offsets.
