The Washington Post just shared the tip to grow your plans from seeds in order to save money, and as great of a tip as that is, it should be obvious to most gardeners. The hardest part is saving seeds to grow another year--and identifying which plants can be grown again from their own seeds or not. As many gardeners know, some fruits and veggies can't be grown from their own seeds--especially some varieties you might buy from the store, and especially if you want the same type you ate. But in general using seeds is a great idea.
I save money by making my own compost. To me, that's the best way to get a good yield, especially if you have chickens or save yard waste and turn it. Honestly my chickens tend to eat a lot of my scraps so I don't make as much from fresh scraps as I used to, but the yard waste sure is helpful. Let a bunch of leaves sit a whole season and the rich soil beneath it is pure gold--and it's free, not counting your own labor. Add chicken manure and you've got some great soil there.
I also save pots, seed starting containers, etc. from previous years to reuse, and I use a lot of found items people give away or throw away--or big sticks in my yard to use to hold up vines. What are you best tips to save money in your garden? Share them in the chat.
