Just over a month ago we planted our indoor tomatoes and our outdoor one's too. There's no surprise that those under cover in the glasshouse have put on a lot of growth compared to those outdoors but when it comes to fruit they're both equal to each other. They're both green and with lack of sun there is no sign that they will be turning red soon. Thankfully, and touch a giant carved wooden rabbit's foot, they have not shown any sign of blight, unlike our potatoes. Keep everything crossed as we do have major problems with growing outdoor tomatoes, hence a large glasshouse and plans for a second one sometime in future when we can either: (1) afford to buy one, or; (2) find one that no one wants anymore and we can cart away. Except the glasshouse has to be 12 feet long to fit in with the other one, and not many people have a 12 foot glasshouse in their pocket. Patience.
So, our cordons are growing well, being fed once a week with comfrey feed on a day when we can air out the glasshouse. You don't want to be trapped under glass with comfrey feed and no air, it feels like your swimming in sewage. No surprise that the sewage farms in the Second World War did a roaring trade in tomatoes on the black market. They naturally came down into the farm and grew happily in the tanks. If you didn't think about it, it was okay but frankly most of the English countryside, especially those around cities, were built on the use of human faeces. See the old fashioned term, gong farming, which is making a come back.
Anyway, now you've put that tomato down and pushed away your lunch, here's a few tips on what to do with tomatoes under glass and when thing go right and when they go drastically wrong.
