Question by robertmaguir

I put 5-5-5 on my tomatoes and 15-15-15 on my lawn. Since tomatoe plants are much bigger than a blade of grass, why shouldn't I put lawn fertilizer in my garden. THX Robert

It sounds good in theory, but grass blades grow much faster than tomato plants so lawns use much more nitrogen during that growth process than plants such as tomatoes. Grasses need a higher ratio of nitrogen, phosphorous and potassium than tomato plants do.

Hope this clarifies things for you.
