I know there are a lot of great ways to store small garden tools.
However my favorite way to organize garden tools is using a 5 gallon bucket with an insert organizer.
This makes it easy to grab and go whenever you have a chance without having to worry about getting the right tools. There are lots of different options varying in price however you can find affordable ones here, here, and here. Or try the DIY approach with these free directions for sewing your own organizer.
Good luck and great gardening!
