Today I repotted the orange.
I had drained the self-watering reservoir a week ago and did not add water since.
The top 4” of soil was slightly damp, as I dug lower the lower was wet but not excessive.
The root ball had not shrunk since 9 weeks ago when I first put it in the pot, the roots looked good. The soil did not have a bad smell.
I reworked the pot same as the lemon so it can’t draw water from below = no self-watering. Now the soil area drains into the lower reservoir and out to the ground.
I did a 35% mix of perlite into the soil and replanted the tree. I made extra sure to pack around the roots using the end of a 1 ½” sq stick.
When finished I spread some slow release citrus food then watered it with 4 gal of Miracle Grow / water. The water sat on top for several minutes before soaking in, kinda strange.
