fertilizing tomatoes

fertilizing tomatoes

I know that tomatoes are heavy feeders from their soil, and that soil needs either a rest or significant nutrient addition or both for optimal growth year after year. Since this is the first year I've grown tomatoes, that's not currently a problem; I used triple mix to start and have topped it up with cow manure twice, and my plants are thriving. (They're in pots, btw.) My question is: I'm a big tea drinker, and up until now I've been throwing my used leaves and bags into the city compost (because I'm too lazy to manage compost of my own.) If I were to start a compost pile with the aim of supplying next year's tomatoes, could tea leave provide the bulk of the nitrogen fixers? Could I just dump the used tea right on my tomato plants without composting, the way I did for my potted swiss chard? (The chard absolutely loved it - I just threw tea bags in there all winter long, broken up first, mixed them in and watered thoroughly before planting, and my chard is doing beautifully.) What's the best way to manage this? I'm not sure I'm ready for full-blown composting yet, especially since I've figured out how to use the city's green bin program fit into my daily practice.
