Here are some photos:
First is of the "heathiest" bella. Some fronds are falling down and brittle, but there's new bright green.
The second pic is the less healthy bella, which might be flat out dead at this point.
Both can be watered until it drips out the bottom, but will feel dry as deep as I can put my finger by the next day.
Next is the Kimberly fern, and this is the "bad" side of her. The other side isn't amazing, tho. It is currently moist maybe 2" down and is sitting in up on rock w water down at the bottom for humidity (100% NEVER sitting IN the water, much lower than the inner pot).
Finally, the last one is my increasingly poor looking Bamboo Palm, who has really gone downhill after the Need treatment...I feel like I initially over-watered so I'm slowing down. I use a dowel to see how moist it is, and it's around half down now. I think everything needs water.
I haven't really gotten a good handle on a good watering schedule...I have a little purple waffle that wilts when it needs water then bounces back, so I kind of let that guide me.
What do I need to do different?
