DIY Mini-Greenhouse

I love starting my seedlings inside in the spring. I always start in late February or early March, even though the plants cannot be put outside until late May. For that reason, I often use yogurt cups, so there is plenty of room for the roots to develop.

What you need for this project:
repurposing salad and yogurt containers to make a mini-greenhouse
10 oz. empty salad container, washed by hand (these are often made of cornstarch and will melt in the dishwasher).

6 empty yogurt cups per salad container, washed (these are rugged enough to be put in the dishwasher when you have extra room).

With the hammer and nail, make two holes in the bottom of each yogurt cup. Do not worry if you create a crack in the process; it will still work.

I put dirt directly into the salad container and then sowed the seeds directly in the dirt. The lettuces will be put out earlier than the other plants, so they don’t need as much room for root development.

Have you found ways to repurpose and reuse items in your garden?

  1. Brilliant use of those salad container. Now I wish I had saved more.

    Yes, I have grown seeds in mini greenhouses like yours…and they really work! Excellent post!

  3. I have tried this, but never seemed to work out. I just wait until I can plant in the yard. I do enjoy being out in the yard when it is warm.

    My dad has decided to grow a little small back yard vegetable garden. But, I do worry, he had a fall a few months back and cracked a rib, he is slowly getting better.

    I saved my little salad containers recently because I thought they would make great little greenhouses. I haven't tried it yet but I'm excited to see that they do work for that! Thanks!

  7. Such a great idea! I’l be starting my herbs in a couple of weeks!

  8. I reuse flower pots all the time. I was given some 5 and 7 gallon containers from a nice man who owns a nursery. Today I was freecycled some kitty litter containers to make a worm compost bin. I’m so excited!

  9. I had a salad container like this set out for this very purpose and while I was napping my teenage son took out the trash, saw the container, and decided it needed to go. :(

  10. I’ve never used those salad boxes, but it sounds like a great idea. Perhaps I’ll get my friends to save me some of them.

    Here’s what we’ve done the last few years, using other recycled containers.

  11. Wonderful!! Sounds like the cure for spring fever as well. Thanks Alea!

  12. Brilliant! I have thrown away more of those containers than I could count. This is a perfect use for them, thanks for the idea and inspiration!

  13. This is such a terrific idea – and a great way to get started on your garden. It’s nice to find a way to repurpose these containers, as there is nowhere I can recycle them locally – and it’s perfect timing to get started on my garden. Thank you for sharing this!

  14. Oh my goodness, thank you so much for this! I am determined to be successful in my gardening this year, and this will be such a huge help.

  15. Another avid gardener here, I do seed starting under lights for some things (eggplant) but more and more do the winter sowing in milk jugs. I’m looking at heading out to the garage when I log off to get the indoor set up going. You should have a great garden!

  16. Thanks for linking up! We also use small containers from the bakery. Happy gardening!

  17. I wish that I saved some of those containers! NUTS!!!! I have the dirt and seeds but no containers. I think that I need to start searching for containers quick.

  18. LOVE THIS IDEA!!!!! thanks~!
