DIY is not only good for the environment but can also be good for your bank balance. DIY Recycled Plant Labels are very easy to make and they add a personal touch to your garden. There are lots of different things you can use to make these that you probably already have at home. Wooden ones are a great idea if you prefer a rustic style. You can write the names of the plants on your labels using paint or markers in your choice of colour. If you are artistic you can decorate them with images as well.
