Someone gave me a very large bag of 22-0-9 fertilizer. I have no idea what the numbers mean or what it might be good for. Suggestions? We have some veggies growing and flowers. We have corn growing in a sand box and was hoping this might be good for it since it isn't doing very well and has never turned a good hardy green color. Thanks.

They show the percentages of major plant nutrients; Nitrogen, Phosphorus and Potassium. They are known as the NPK values. N - Nitrogen: promotes the growth of leaves and vegetation P - Phosphorous: promotes root growth K - Potassium: promotes flower and fruit growth
What you have been given is very high in nitrogen, possibly too late in the season for veges unless you are starting a second crop. Normally at this time of the year you would use a fertilizer high in potassium to promote flower and fruit production. You could try it on your corn. I doubt it would do much harm. I do not know anything about growing veg in sandboxes though so I could be wrong!
