Moving Citrus outside and repotting
A few questions regarding my Meyer Lemon Tree:
1) I'm in Zone 6 (NYC) and I just moved my lemon tree back outside to catch some sun. It seems to be doing well and there's some new growth; I am planning to prune the dead branches soon and then re-pot. Is there a conventional wisdom about how long to wait in between changing the environment, pruning, and repotting to not cause too much stress?
2) Last time I repotted this tree I used a citrus mix from my local plant store that seemed ok- but I notice that a lot of people on this forum are not fans of premade mixes for citrus. Any suggestions for a citrus mix that a noob like me could use?
3) I bought a self-watering pot from Ikea. I was wondering if anyone has tried these pots with citrus, and any feedback on if they work well or if there are any suggestions about them? One thing I was going to do was add a drainage hole above the water reservoir, and block the hole with rocks so the soil doesn't spill out.
