Checking with my cheap pH meter, the pH would go down to 6.5 or 7, then pretty quickly back up to 7.5 or 8.

Roots on Namwah today. Yes, it was recently watered. No, it wasn't that wet constantly.



I had the same idea to go up to a bigger pot until I can plant them in the ground. I thought maybe the sun was baking the roots by shining on the side of the small black nursery pots the bananas are in. Looking at the root ball on one of the Namwahs, the roots seem like they were mostly killed at one point, but the lower ones look like they are growing and branching out now.
