Thank you! I moved it so that it gets morning sun and afternoon shade. It's doing soooo much better! I added some mushroom compost, and I also drilled holes in the sides to maybe get more air to the roots.
This is a sub irrigated bucket. Water is drawn up from the bottom, instead of me watering from the top. This has saved me lots of water! Just about all of my above ground planters are sub irrigated.
