Please can someone help me,i have a ficus bonsai now for 2 years,since the very first months leaves started to fall,then some new ones did start to grow,but for the very last year there are more falling then new ones,a month ago i changed the pot but it seems that the soil doesnt get the water very good,it takes some time to absorb it and the leaves have fallen more. Please can you tell me what should i do,i have used fertilisers also. Thanks
