Try the products from Gardens Alive! company. Keep up with the compost. Do you garden in flat grounds, or raised beds? I would advise using raised beds with a mix of high quality compost and topsoil. If anyone has leaves left over from last fall, add about 20% coffee grounds to them, and it will make the best compost around. This is all the nutrition your plants will need. Apply a two inch layer on top of the soil. Good luck. Keep updated during the growing season.
