A few weeks ago I shared my Easy Eggshell Seed Starter DIY on my Instagram stories and I’ve received so many questions about it. One thing I absolutely love about this project is that everything you’ll need to complete it can typically be found in your home.
There’s something so nostalgic about watching something grow from the very beginning in your own home. Now, I am not trying to pretend that I have a green thumb, but these seed starters are basically fool proof. Trust me, if I can these little beauties to sprout and flourish then anyone can.
Are you ready to learn the 4 simple steps to growing beautiful flowers from your own home? Let me walk you through this easy process.

Easy Eggshell Seed Starter
Can I share a little secret with you? For the last few years, I’ve completely neglected all forms of green life around my house. Before I had Berkley, I landscaped our whole yard and then something happens after you have that third child. Call it hormones or complete exhaustion, but I just let it all go. Until the infamous quarantine of 2020. What a better time to get my ish back together then now, right?
So after I bought and planted about 40ish new plants so far this Spring, I decided to grow some mammoth sunflowers to plant in front of our barn. You can use the steps below to grow anything from vegetables and herbs or a variety of flowers and plants. This tutorial below is exactly how I did it.
SUPPLIES FOR AN EASY EGGSHELL SEED STARTER
Cardboard Egg Crate
Eggshells (rinsed thoroughly)
Small Cup with Spout or Spray Bottle
HOW TO PREPARE AN EASY EGGSHELL SEED STARTER
Now that you have all the supplies, it’s time to get to planting!
Step One: Rinse the eggshells
Prepare the eggshells by thoroughly rinsing them. DO NOT skip this step. Trust me. I learned from experience if you don’t rinse the eggshells well, they will stink and no one wants this fun DIY to turn into their house smelling like rotten eggs.
Step Two: Fill the eggshell seed starter with potting soil
Once you’ve thoroughly rinsed your eggshells, place them in the egg carton with the opening facing up. Each egg once cracked in half should make two small eggshell planters. You can save the rest for future planters or toss them. (TIP: Broken egg shells make great fertilizer for plants.) Now take a small scoop and fill your eggshells about 3/4 full.
Step Three: Plant and water the eggshell seed starter
Gently press the seed into the soil and then sprinkle a small amount of potting soil over the top, just enough to cover the seed. Repeat this step for all eggshells. If you are planting a variety of seeds, make sure to label them. You can do this by either writing directly on the eggshell, writing on the egg crate, or writing on a clothespin and clipping it to the outside of the carton. Take a small cup with a spout and lightly water each seed. If you don’t have a tiny cup with a spout, then use a spray bottle and spray each seed with water until the top of the soil is wet.
Step Four: Pick a sunny location for your seedlings
It’s really important to find a warm and sunny location in your home for your seeds to germinate. In our home I use the windowsill in front of a large window that overlooks our pond. It stays sunny most of the day.
If you don’t have a sunny location you can purchase a seed starting heat mat to place your egg carton on that will provide it with the heat it needs to help the seedlings grow.
Caring for the Eggshell Seed Starter
Step One: Water the seedlings
It’s important to keep your seedlings moist without over watering them. You don’t want to drown them so balancing watering with sun exposure is so important. Continue to water your seedlings every other day or so. Even stretching to every third day would probably be ok.
Step Two: Harden Off the Seedlings
“Hardening Off” is a common term referring to the transition of your indoor seedlings to the outdoors. Before you transplant your seedlings in the ground, you’ll want to gently expose them to the change in climate so they don’t suffer from shock of the sun. You can start this process once your seedlings are a couple inches tall or have a second set of leaves.
To harden them off, place your seedlings outside for a few hours. Then gradually increase the amount of time and exposure each day so the seedlings will acclimate to the new weather changes.
Step Three: Transplant Your Seedlings
Whether your transplanting your seedlings into a pot or directly into the ground, gently crush the outside of the eggshell so the roots from your seedling can grow through the cracks and into the soil. Over time the eggshell will biodegrade and provide nutrients to your plant.
BENEFITS OF AN EGGSHELL SEED STARTER
There’s so many benefits to using an egg crate eggshell seed starter. One of the biggest perks is how cost effective it is since you normally have these materials already on hand.
I love how environmentally friendly egg crate seed starters are. I know “organic” and “clean living” are very popular trends right now, but this project truly is as organic as it gets when it comes to starting plants from seeds. There’s something comforting about gathering items from your kitchen and starting your own garden without having to run to the store.
Since eggshells naturally decompose on their own, this is a great way to compost and provide essential nutrients to your plants. Egg shells are also made up of calcium carbonate which is an essential nutrient for plant growth. After transplantation, the eggshell will break down and provide the soil with calcium and nitrogen.
Now that you are educated on how to start an easy eggshell seed starter of your own, tell me what do you plant to grow first? I hope this tutorial inspired you to use items you already have at home and grow beautiful plants of your own to enjoy!
