Rookie here and hence don't have much of an idea or the guts to cut as required. I have a ficus with long lanky branches and and was wondering how to make cuts to make it more compact and tree like? Please could you help with some advice on how can this be made into a decent
bonsai? I am also noticing that most of the new leaves are becoming very yellow and blotched and falling off. Not sure if its over watering but I have been watering almost once a week going into start of summer or when the soil is dry at the top.

Thans in advance for your help
