Leaf mould has no nutriuent for growing toms which need plenty of potash to get good tasting fruits. You would have done better to grow them in a growbag. The best way is to insert a fibre bottomlest ring about 10" dia into the bag, fill with compost and grow your plant in that thus giving the plant all it requires, but water regulary and feed at least 2-3 time a week when its growing well. Keep this info for next year. One more tip, never buy plants with a thin black leg (base of plant) make sure they are green.
