I maintain a tiny balcony garden. For my work, I have to live for extended period in different countries. Right now I am in a city in China. Weather here is a little strange for me. Temperature and amount of sunlight fluctuates a lot. These days the temperature is usually between 20 and 30 deg C and it is mostly cloudy and rainy.
I usually love to grow different foliage but this year I tried growing several herbs. Mints are growing great and wild. Citronella is also growing well. Sage and Rosemary are in sort of non-responsive state. They are neither growing new leaves, nor in a bad shape. I actually bought two Rosemary and just one survived. Oregano and Thyme are in bad shape. Nearly dead. The soil is moist but not too wet. Leaves nearly all dried up. One of the herbs that I love most but have not been successful is Basil. I bought some Lemon / Thai Basil in the beginning they had tough time surviving and after a long time, they are alive but not growing much. I bought a pot of Sweet basil which had three plants in it. They were not growing much so I pruned them but it did not help. I thought they might be having space problem and so separated the three in to three separate (larger) pots. Since then they are having tough time. I am not able to make out what is going wrong with them. The soil is moist but not wet. When I place them in the balcony leaves seem to start falling more then when they are in the room. At times an entire stem droops down and eventually I have to pinch them off. I am trying to avoid watering them as I am not sure about the problem. I loosened the soil a little and mist the plants about once in a day.
Kindly advise what can be done to help my herbs grow well. Where am I going wrong ?
