Hello. I would like to start a small vegetable garden. I need to know what plants are too late to start from seeds and what plants I need to buy already planted and just plant in my garden. I would like to grow bell peppers (green,yellow,red), lettuce, tomatos, cucumbers, strawberries, corn, watermelon, and squash. I would appreciate any other tips you have as well! Thanks. I am looking to plant these sometime this weekend if it is not too late!! :0)
