When watering use the wet and dry cycle .
Add a little water to top of pot to wet then wait a minute or two before watering again till you see a little run off at bottom of pot .
Water usually every two to tree days , enviroment and potsize & plantsize will dictate this .
Wait till roughly the top inch of soil is dry before next watering , dry but not so dry soil is coming away from side of pot .
Another pot the same size filled with dry compost is also a weight guide . I lift my pots to judge sometimes .
