An interesting thing I heard this winter was to put tons of banana peels in, which makes your compost very high in potassium. Potassium is the essential nutrient for flowering and fruiting vegetables, such as tomatoes and peppers (it's the K in the N-P-K number on chemical fertilizers). After doing that all winter, I put a handful of vermicompost in each planting hole when I transplanted tomatoes into the garden, and they are going crazy! In fact, I have one Early Girl Tomato that has over 50 tomatoes on it right now!
Here's a site someone just sent me that has the most thorough and helpful explanation for how to set up your own bin: Red Worm Composting.
More on vermicomposting some other day, time to play with the kidlets!
