Thanks so much silentrunning and joyjoy 3333 for your replies!
To joyjoy3333’s response: It is possible that the smaller roots were cut off when being transplanted. I’ll have to be more careful about that in the future. I’m not sure I’m over watering them, but I’ve not been staying on a good watering schedule, do you have any tips on that?
To your suggestion, silentrunner, I will be sure to collect more soil along with the roots. I feel like accidentally cutting off some of the roots was the problem here.
The last question I have is, if cutting some of the roots off is the case, are there any steps I need to take to ensure the plants keep on track with growing well?
