Planted in my garden are eggplants, zuccini, yellow crooked neck squash, cucumbers, tomatoes, bell peppers, cayenne peppers, green onions, and sunflowers. Not all of my plants are changing colors, and the ones that are turning colors are not next to each other. Some are on opposite sides of the garden, that’s why I think it is something in the soil. I can’t find the answer to this problem ANYWHERE!!!!!
