The Best Spring Fertilizer for Ohio

Tailor your spring fertilizer to what you are planting in Ohio. For tomatoes, use a 5-10-10, 5-20-20 or 8-16-16 ratio of nitrogen, phosphorus and potassium, the Ohio State University Extension recommends. For roses, test the soil to see if the pH is above 6.5; Ohio soils often need iron sulfate to address deficiencies in iron for higher pH soils.
