My summer hobby is tomato growing. I cater to thier needs and check them often until I find the ones that are just perfectly ripe. Just so, that they are both sweet with a bit of acid. Some are eaten that day as slices on the plate, others may be canned or even sun dried and then stored in a clay covered pot with basil and olive oil for future soups and such.
My tomatoes are the very best and extremely tasty. The secret is the soil, the constant care of vines and a good compost brew. I use probably one quarter of my total refuse in the form of what is considered worthless garbage. This might include coffee grinds, egg shells, banana peels, potato peelings and much more. Some who compost even use leftover meat and bones. I wouldn't advise this, as it might create a stink with the neighbors and attract undesirable animals or violate municipal health codes.
Not only does a good brew create better growing conditions for anything, but it also diminishes the need for fertilizers which effect the composition of soil and create environmental concerns.
