Good evening, some help please! I have a Chinese Elm which is around 6 years old. I've neglected it somewhat throughout the summer and would like to get it healthy again. Though I have been watering it the soil has compacted and shrunk, I would like to re-pot it but many posts say that spring is the correct time. Small, stringy roots have started to come through and it is generally looking tired. I stupidly picked the moss off the top. If it needs re-potting could somebody tell me the best type and where I can get a full kit including what I would need. The current pot is about 6'' long, 3'' wide and 2'' deep.
I appreciate any advice.
