Gardeners should find Vegetable Planner by Steve Lucas of Cheadle Hulme, Cheshire, a useful guide to vegetable growing. On the first screen, a chart shows you which plants should be grouped in a plot and rotated every year.

You can then choose to look for any particular vegetable and find out when the plant it, where, and in what type of soil; or you can enter a month and discover which vegetables are to be sown or harvested at that time.

The program lists more than thirty types of vegetable and you can, of course, alter the data to suit your needs. Vegetable Planner will run on both the Electron and BBC B.
