Harry's All Purpose Plant Food is the complete package for plants in pots. This fertilizer provides both slow and fast acting nutrients. It feeds the plant as well as replenishing nutrients and trace elements in the potting mix. The addition of a soil wetting agent encourages the retention of moisture. Nothing else is required. Simply apply in September, December and March. More often if required to maintain healthy growth. 

This all purpose fertilizer can also be used in garden beds.
