Vegetable gardening with a theme can be great fun for all ages. A theme garden is the perfect way to get the kids outside enjoying nature. Involving them will provide a sense of responsibility as well as accomplishment as harvest time draws near. Plus, it’s a great way to get them to eat more veggies! For a pizza garden, plant foods such as tomatoes, green peppers, jalapenos, onions and a host of herbs and seasonings like basil, oregano and thyme. Other theme ideas to try are stir-fry or salsa gardens.
