I have removed a few more of the lower leaves to help ripen the fruit slightly and give some good air circulation, as I have been spraying the tomatoes with water to keep them cool. I wanted to make sure that the lower part of the plant dries out by night time.
It certainly has been hot in the poly-tunnel these last few weeks, over 30 degrees some days, that's the problem with a plastic covered structure. As I have said I do cool the plants down with a fine water spray, some people will say that this will cause scorch on the leaves, but I did this even in Portugal where it was a hell of a lot hotter in the poly-tunnels with no scorching.You do need to keep the humidity levels up in hot weather to help the flowers set, so spraying also helps with this.
Good ventilation is also important and it is about time to leave the doors open at night, except on windy or colder nights. I have netting on the more exposed doorway to help stop any wind damage. Bramble in on patrol to make sure no one steals my first ripe tomato.
The marigolds are doing their job stopping most of the white fly from feeding off the tomatoes. You will see plenty of whitefly on the marigolds, but a lot less on the tomatoes. A dousing with diluted washing up liquid also helps keep them at bay.
Twisting and shooting is another regular weekly task, just remember that your plants need to be twisted clockwise around the string, as this is the direction that they follow the sun and would untwist themselves if you did it anti-clockwise. Also make sure that the string passes above the trusses, or as the plant grows it could put pressure on the stem of the trusses.
Do not forget that I have a new questions page at the top of the blog, just ask you question in the comments section there, or on the page of a relevant post.
