I know most people have already put their tools away and their beds are ready for winter. It may be too early to even think about next year, but the off season (winter) is planning time for next year. It’s time to figure out what worked for the 2007 season and think about what to plant in 2008. The University of Tennessee Gardens website has some great information about annual plants from their 2007 annual plant trials that may help the planning process. They tested the same annuals in Jackson, TN and in Knoxville, TN then rated them for June, July and August. On the site they show the rating for each location on a scale of 1-5 (5 being the best) and gave an average of the two locations. This information is a very good resource for a gardener wanting to find a new annual to put into the garden next season. They also include a picture of each plant with the results.
