How often should I fertilize my garden?

Tracy DiSabato-Aust (Garden Designer and Author) gives expert video advice on: What is 'fertilizer'?; What is the difference between fertilizer and soil amendment?; What are the primary nutrients that plants need to grow? and more...

How often you fertilize often depends on the type of plant grown and the nutrients that are available. I like to advocate the use of a nutrient-providing soil amendment, and when that is in the soil, you have a living soil and nutrients are being provided throughout. Very seldom do you need to add additional fertilizer, except perhaps with some of the heavier-feeding plants. An example would be delphiniums.
