Soap box again!!
Okay, I know I have talked about this before. But growing your own food is an excellent way to save money, plus do something healthy. Growing & eating out of your own garden cost less money, plus it forces you to eat seasonally. Eating seasonally keeps you in food that has a low carbon foot print. It doesn't have to be shipped from across the world in order to eat it.
Food for thought :) what a pun I know hehehe
