Oh, dear, Josephine. Thank you for the complement, but i doubt the BBC want or need an 83(yes, I've had my birthday)year old employee. However, two minds are better than one and there might have been something nasty in your own compost unless you sterilised it. I've had a lovely crop of tomatoes in big pots, starting off in the conservatory and then taken outside, ut the may have to come in to escape the blight as Bristol is having hot, humid, weather. Do let us know if you find the culprit so we can all benefit - forewarned is forearmed.
I'm going to Barrington Court for a birthday treat tomorrow so will let you know any tips I pick up there, as they are great on fruit an veg. which they grow for the restaurant.
