Hi Marianne and Bambi, If you are needing nitrogen for greening, and all other nutrient requirements have already been met, it is better to go with nitrogen alone, like a 21-0-0 or weaker if that meets your needs. In container plants there is a real problem with build up of unnecessary chemicals like potash, potassium, etc. Some of these will cause more problems like locking certain nutrients into the soil or planting medium so that more is actually less when it comes to meeting a plants requirements for healthy growth and blossoms. This can happen in your garden soil as well as in container gardening.
