re: Gardening advice

Depends. Are you trying to save money on your food bill or are you doing this to see how big you can grow tomatoes.

If you have Thriple 13 use it but be careful not to burn your plants.

Cow Manure is great but an over dose of it can cause your vegetable plants to grow like weeds but produce less in the way of food.

A great free source of fertilizer is stuff we usually throw away. Fish scales, all sorts of stuff you can mulch.

I prefer the less is more approach. I don't want to spend 300 dollars just to harvest 100 dollars worth of vegetables.
