Some use commercial tomato feeds like me, others use teas of different kinds (“teas” here are the result of diluting the liquid formed from decomposing green stuffs or even from cultivated worms!). Some people add crushed egg shells for calcium. Other people swear by seaweed extract, especially for foliar feeding. Some people use coffee grounds as a fertilizer.

Tomatoes are heavy feeders so they certainly need a lot of nutrients!

If you do crop rotation, plant peas in the season before you do the tomatoes. The extra boost of nitrogen is great when tomatoes are just starting out (but not when they should be fruiting).

I have to give a big thumbs up to worm casts and worm teas too! Seaweed tea is also very good as a foliar feed. It actually strengthens the leaves. Don’t worry, it’s not going to cause fungus or generate poisons!

Seaweed extract is available commercially.

Also, be careful with going overboard with the coffee grounds – it raises the acidity level of the soil.
