My neighbour told me to nip out the first flowers on my growbag tomatoes, to encourage more later on. Is this correct? (I've taken her at her word and got rid of three trusses of flowers)
Hi Brian, your problems sounds like whitefly. They shouldn't cause a big problem to your tomato plants, as long as you keep them under control. Follow the advice on the linked page above and you should be fine. Kate
I have 6 assorted tomato plants in grow-bags in the greenhouse which don't seem to be doing much at present. However, I also have 2 large plants (4ft) which were given to me(haven't a clue what variety they are). These have 4 trusses, some fruit, but the leaves are curling & turning slightly yellow. What am I doing wrong please???
Hi Lewis, when your tomato plants are flowering you should make sure insects, such as bees have access to the plants so they can pollinate the flowers to ensure they all turn into tomatoes. You may also want to feed the plants with a high-potash fertiliser, such as comfrey, which will promote more flower growth, and increase your tomato yield. The following How to project may help: Care for greenhouse tomatoes.
Gillymiff - are you feeding your tomatoes? it sounds like a deficiency probably of magnesium which can be remedied by sprinkling a pinch of Epsom Salts (from your chemist) around the base and watering it well in.
john w. - If you buy some liquid seaweed plantfood from your garden supplier it will help setting and general health. if you spray a dilute mixture around the flowers sometime in the middle of the day it helps the pollen grains to do their job. I think directions may be on the bottle in fact.
