It’s started to warm up here in LA and our early summer veggies are growing like crazy! But I thought I would get some late summer veggie seeds started so we can replant mid summer and I’ve got a tutorial on how to make Egg Carton Seedling Starters, made with a great fertilizer: coffee!
Coffee grounds are great at adding nitrogen to the soil! My husband has been saving our used Starbucks® Pike Place® Roast coffee grounds so I can use them for these egg carton seedling starters. But did you know that one coffee tree produces only enough coffee cherries each season for a single pound of coffee? And aging trees, or those impacted by disease, produce much less? That’s some scary news for us coffee lovers! But in September of 2015, Starbucks launched its One Tree for Every Bag Commitment to help ensure the long-term supply of coffee and the economic future of coffee farmers. For every bag of Starbucks® 10-12z & 20z Ground or Whole Bean coffee purchased at participating Albertsons Company stores in the U.S. from May 1st through May 28, Starbucks provides one disease-resistant coffee tree to a farmer in Mexico, Guatemala or El Salvador. Starbucks® will donate 70¢ to Conservation International for every bag of coffee sold at participating Albertsons Company stores in the U.S. from May 1st through May 28 to foster thriving coffee communities.

I love that our daily morning ritual of drinking a cup of coffee can help both in our garden at home as well as on a coffee farm faraway. We all need a morning pick-me-up, so why not choose the morning pick-me-up that also helps to ensure the long term supply of coffee and economic future of coffee farmers? Papier-mache egg cartons are PERFECT for starting seeds indoors. The papier-mache weakens as you water the seeds and by the time they’re ready for planting, the papier-mache can be easily torn apart and each egg cell can be directly planted into the ground! They’re super simple to make, you just need a few supplies:
- Paper egg carton
- Plastic Wrap
- Potting Mix
- Used Coffee Grounds
First step, cut off the lid of the egg carton (and side tab if it has one) and set it aside, we’re going to use it later. Next, punch a hole in the bottom of each egg cell to allow for drainage and for any plants whose roots might not be able to grow through the paper. Then “plant” 2-3 seeds per egg cell. Of course, I went with some silly named plants like Rainbow Sherbert Watermelons and Little Prince (Purple) Eggplants. And some Catnip! Next, I mixed used coffee grounds with some potting soil as an added fertilizer. Coffee grounds are great at adding nitrogen to the soil! Then I topped each egg cell with a bit of potting soil and tapped it down a bit. And then just give them a misting of water with a water bottle and store them in a warm space. Direct sunlight isn’t necessary. You can also add used coffee grounds to your existing plants! We already have a baby tomato growing! And the corn is shooting up everyday! I picked up our Starbucks® Pike Place® Roast ground coffee at Albertsons. Check out the special Starbucks “One Tree One Bag” commitment display in the coffee aisle!
