Hi there! As the title suggests, I'm hoping for some advice on how to approach recent leaves yellowing/dropping from an Improved Meyer Lemon tree I moved indoors about a month ago. I've been doing some research and am concerned I'm dealing with root rot/lack of drainage, as I believe my pot is too large and I likely planted in an undesirable medium (I'm a novice gardener, so assumed bigger pot was better for the tree and off the shelf soil would be best--silly me). For some background: I purchased an Improved Meyer Lemon this spring and planted it in July in an 18" ceramic planter with a mix of Miracle Gro Cactus Palm and Citrus Potting Soil Mix, Red Cedar Mulch/Bark, and 5-5-2 fertilizer After a successful summer outside with some pretty considerable growth, I moved the pot inside exactly a month ago on October 23rd I'm a miser and our in-home temperature hovers around 60-70 degrees F (16-21 degrees C) and relative humidity has been hanging around 50% according to our thermostat There have been a handful of leaves that have now dropped off, but nothing major. The leaves that have dropped have looked fairly green and healthy for the most part. Some leaves yellowing as well as noted in the pictures. I dug down in the soil about 7.5cm and would say the soil is "moist". I didn't notice that it is overly wet, but only the top of the soil is remotely dry--it seems that having the large pot outdoors wasn't an issue since plenty of heat and sun helped water evaporate, but indoors the large pot is too much. I have only watered lightly once since bringing the plant in, about 2 weeks ago before a slightly misting near the trunk I did today I am using a GE BR30 bulb to supplement light The plant is now just under 1 meter tall I'm considering re-potting in a smaller pot with better a better soil mix, but given I haven't lost too many leaves yet, I also don't want cause additional stress. Any thoughts on getting ahead of additional leaf loss/damage would be truly appreciated! If there are other details or photos that would be helpful for identifying potential issues, definitely let me know. Thanks so much!
