I like your pics Suzie thanks! Dont forget to pinch sideshoots, or leave them if they are bush / cherry type. When the first flowers appear feed twice a week with a comfrey or nettle soup. Always ventilate well and water evenly to avoid split fruit.
Keep an eye open for blight around August, I also use marigolds as companion. Watch for slug attack on them though!
Looks a grand set up, good luck!
