If you want to save big then make 2015 the year you grow a garden. Here are a couple of examples:
Leaf Lettuce or Swiss Chard - both very easy to grow and will keep producing if you keep them watered/nutrients and cut them regularly.
Grow yourself - $3.00 package of seeds, plus possibly some other costs that will be utilized in future years. Versus buying one bunch a week at the store $3.00/week for 12 weeks or $36.00.
Savings is $33.00 on one veggie Honestly purchase a pot, add some soil and seed and grow it on your deck.
Carrots - 100 seeds in one $3.50 package compared to buying a bunch of 8 carrots at $3.20/bag - Savings assuming 80 carrot seeds grow would be $32.00
Strawberry plants - get some runners from a gardening friend cost free compared to $4.50/box at the store....10 boxes from a small bed of your own - Savings $45.00
and on and on. Just those three garden items grown save $110! What are you waiting for, start planning what you can grow either as a community gardener, patio gardener or home gardener.
Make 2015 the year you grow a garden and start saving.
