If you have planted potatoes late because you have recently taken on your plot, or if you are trying out planting late summer for new potatoes in the autumn, you need to be aware that there is a very great deal of blight around right now, and the humid warm conditions mean it will spread quickly.
Potato blight also affects outdoor tomatoes. It is worth taking extra care not to allow blight to infest your plot from year to year. You can protect potatoes, as well as tomatoes, from blight by spraying with Bordeaux mixture.
