Looking for plants and gear for your garden? A plant nursery might just be what you're looking for. The biggest clusters of growers can be found in Somis and Santa Rosa Valley. These are generally locally owned and operated. Along with your plants, you'll also get advice and personalized help. Other options are to try the garden centers of department stores like Target or K-Mart, or home improvement stores like Home Depot. Advice at these can be hit or miss. Smaller stores like B&B strike a good balance between conveniently located and helpful staff.
