This is my first bonsai ever and I am just looking for some info on caring for it, i have read a few threads and decided to give it a go. It is a juniper squamata and i purchased it from a local store it was i a black pb bag and extremely rootbound in the bag so i ended up having to get rid of quite a few of the roots. For the soil i used yates potting mix with cat litter which is zeolite as i read that is a suitable as bonsai soil-I sived the cat litter to get rid of the dust and very small particles. I trimmed the tree quite alot already even though there is still a large amount of foliage. when trimming I focused on trimmig everything that was coming off the bottom of the 'branches' if thats what you could call them. then I put some moss that was in a corner of my back yard on the top. I also places some small rocks under some of the branch like roots.
Do i need to trim it more?
Will the soil mix I used be okay? etc etc etc
Any of your criticism would be appreciated.
