Looking for a creative way to repurpose your plastic salad containers? Make my free DIY garden plant markers that transform your trash into practical, weatherproof plant markers for seedlings in your garden.
My free DIY printable garden seed markers are made from recycled plastic salad containers. The packrat in me always kinda feels bad about throwing these clamshell salad containers away so thought I’d try to make something useful from them. And aha! I thought that the salad container plastic could make a great waterproof outer case for garden plant markers for seedlings.
DIY plant markers for seedlings from plastic clamshell salad containers
This year we decided to 86 buying flowers for our deck and instead just grow vegetables and other edibles. So far Elise and I have planted tomato seeds, lettuce, and basil.

These seed markers not only help you keep track of which seeds are what but they also show plant maintenance and care including watering instructions, thinning distances, and harvesting guidelines.
The geometric design was inspired by these pretty graphic patterns that I first saw on design*sponge and uses the super cool font Blanch from the Lost Type Co-op.
And bonus! This project gave me an excuse to use one of my favorite hardware store materials: colored electrical tape. I love love love colored electrical tape. It’s kind of like washi tape but more flexible and also waterproof.
Hopefully, we’ll have a good growing season in Chicago. And with our budding lettuce crop, Elise and I will hopefully have to buy a lot fewer plastic salad containers this summer.

How to make DIY garden plant markers for garden seedlings from recycled plastic salad containers:
Step 1: Clean the recycled salad container
Wash and dry an empty salad or spinach container. You can also use carryout clear plastic containers from restaurants such as the ones from Homemade Pizza Company. Peel off the labels as much as you can. Then give it a soak to remove the rest of the paper bits, dry it off and then use a little bit of Goo Gone to get the rest of the sticky part off. Dry the clean plastic salad container and set aside.
Step 2: Print and cut garden plant markers
Here are all of the cut out garden seed markers, fronts and backs.
Step 3: Cut plastic fronts and backs for waterproof DIY plant markers
Lay out the garden seed markers on your salad container and trace with a Sharpie pen. I was able to get five pieces from the salad container top and cut the sixth from the bottom.
Cut out the garden seed marker front and back from the plastic salad container lid.
I was lazy and left a little bit of the Sharpie on the sides. But I didn’t really notice it later once it was covered in electrical tape so I think it’s OK to be a bit sloppy with it.
Step 4: Sandwich paper between plastic to make waterproof seed markers
Put the blank sides of the garden seed marker front and backs together.
Sandwich them between clear plastic sheets on the front and back.
Step 5: Cover sides with waterproof electrical tape
Now for the electrical tape! Start with the lower edge, placing the tape half-way lengthwise on the front. Cut the tape.
Wrap the other half of the tape around to the back. Repeat on the other side. Then tape the bottom up so it’s nice and water tight.
Move your way up, taping the left and right sides again so the tape wraps around the garden seed marker lengthwise.
Repeat on the other side of the garden seed marker.
Now tape up the top of the seed marker to seal it all up from the elements.
Repeat the plastic salad container sandwiching and electrical taping for your other garden seed markers. Then off to the garden!
