minor issues with 5:1:1 mix
I got a meyer lemon a few weeks back and planted it into a terracotta pot. Since I am now down at my apartment I have been having issues on where to keep my trees so they get enough light. I have only one south facing window and my two oranges, another lemon and a lime take it up. So i have been putting my tree outside in front of the window, since i live on the basement level and the bottom of my window is close to the ground.
A few days after i put the larger lemon out there, leaving started curling, turning yellow and falling off, so I took it inside, figuring the 95 degree days next to a stone wall, blacktop and the siding was roasting it. So i took it inside and put in on my desk.
I have watered it a few times inside and each time, a lot of the water runs right through it, the way the mix is designed so i figured that was the lack of water that caused the leaves to turn as well. I have also had problems with the overflow when i water, the pan at the bottom doesnt hold too much so when i watered it the other day, everything just overflowed so two days ago i watered it again with a maybe a quart of water (for a 27 inch high tree in a 14 in pot) and the water almost overflowed as well. Later in the day i checked with my dowel and only the bottom two inches were wet or damp. So i am concerned that the tree does not get enough water so i have been leaving it indoors but that still doesnt appear to be helping
My question is how can i amend this to make it hold more. I think i read that josh puts more bark on top of his or mulch or can i just add a thin peat layer on the top?
And for a last thought, I have been trying to keep my window open so the mixes dry out faster and prevent root rot.
