Cherry tomatoes - ripening!

Yummy! Finally edible cherry tomatoes after so many months and after so many tries!!! So what's my trick to planting cherry tomatoes? I dunno actually! I tried planting them on the ground and they are died on me. So planting on the box helps but my neighbour's was not successful. Guess it is the soil? I did soil-compost-soil mix! Mulch with dried leaves on top. So far, I topped up the soil only once. Added epsom salt twice. Fertilised a little with chicken manure and also seaweed a couple of times. My plants do not appear to be fantastic - not as bushy as those that I have seen! But at least they bear me SOME fruits!! Happy!
