In wintertime a gardener’s mailbox is overflowing with nursery catalogs. Ordering plants through the mail greatly increases the variety of plants to choose from, but also carries some risk. Is the company reputable? What if the plants are low quality? Lower that risk by reading customer opinions of the mail-order nursery in question. The free database at Garden Watchdog lists over 3,000 garden related vendors where customers can submit compliments, complaints or warnings. Businesses can respond to complaints to give their side of the story. This site can also be used to find all the nurseries that sell products in a certain category, like bulbs or hand tools.
