Use fertilizers high in nitrogen for sidedressing such as nitrate of soda or blood meal at the rate of 1/3 cup per 10 feet of row. You may also use lawn fertilizers that have close to 30 percent nitrogen such as a 30-3-4 or 29-5-4 but the rate should be cut in half to 3 tablespoons per 10 feet of row. Do not use lawn fertilizers that have weed killers or preventers. Fertilizer must be watered in if timely rains don't do that job for you.
We have a sheet available that gives recommendations on how to sidedress specific vegetable
crops. It can be found at: https://tinyurl.com/j2ggaa6 (Ward Upham)
