Every year I try to grow tomatoes - and every year they succumb to illness. I have 3 plants in 11 inch pots in a mini greenhouse, and 2 in the same pots outside on the patio.
Every year previously I have bought plants but this year they are grown from seed - 'maskotka'. As soon as I spot diseased leaves I take them off and spray the plant with a washing up liquid, bicarb and water mixture, but this time it seems to have spread to all the leaves despite this. They have been given liquid feed, and I used fresh compost. What has worked for you, and what varieties do you recommend for disease-free plants? Thanks
