Alllllright. I am new here. I am a plant lover who usually kills everything I grow. It's tragic. I have just moved to Madison, WI. The last person who lived here planted all these plants and this garden in like a sandbox. She has a compost bin in the back. I've been watering everything when it looks dry, so far so good. But should I be doing anything else? Should I be adding fresh soil or anything like that? I don't even know what to do with the compost bin. My other question, is about plants I bought today. We went to the Famer's market and I bought a flower plant and four herb plants. I bought lemon balm, oregano, basil and lavender. I would assume everything but the lavender should stay inside. Help?
