Finally you will have a stinking mess. Blight can also be evident as white mould on the underside of the leaf. Blight can be prevented, but only before it is evident. Copper fungicide ( Bordeaux mixture) is the best, applied July onwards at roughly 3 week intervals. However, many people don’t like the thought of that, even though it’s organic, so perhaps you might like to look at blight resistant strains in subsequent years. Once blight has set in, it is essential to cut the plants down to ground level and remove the foliage to the tip. Do not compost. Hopefully, the infection will not have reached the tubers and they can be safely left for 2-3 weeks, sometime more. Do not grow potatoes in that area for a year or two. Find out more, here.
August Sowing – Several people, including the latest plot holders have asked what can be grown this time of year. Good news! There are a few things you can grow... Spring cabbages are good to sow right now, Durham Early being a classic. Japanese onions and lettuce are quite often sown around now too. I am still trying to get to grips with the difference in climate from where I lived in Yorkshire, so I am experimenting too. Late Brussels sprouts might work and it may not actually be too late to grow winter cabbages, sprouting and spring broccoli, possibly even spinach beet, but if you grow these, you will be joining me in testing to see if it’s possible. Please do check garden centres for any remaining plants they have left; probably not many now, but there’s a chance.
