Mini Valentine’s Day Terrarium in a Mason Jar
Mini Valentine’s Day Terrarium in a Mason Jar: how to transform an old mason jar into a beautiful mini terrarium for Valentine’s Day.

Valentine’s Day Gift Idea
I thought it might be sweet this year to make a little teacher gift for Valentine’s Day. I loved how my terrariums that I shared here turned out, and decide to make a mini version. This terrarium in a mason jar will make a perfect gift.

How To Make A Terrarium In A Mason Jar
1. My favourite brand of tomato sauce comes in a mason jar. I usually just recycle it, but last week I saved a couple, and spray painted the lids pink -you know how I love spray paint. 😉
Components of a Terrarium
2. We started with some rocks in the bottom for drainage, added a little charcoal (find it in the aquarium section of your local pet store, labelled Active Carbon) to help fight against mold issues, and then some potting soil.
3. I used some little woodland plants, one in a darker green, and the other in a more lime, bright green.
Polymer Clay Hearts
4. Because these are for Valentine’s Day, I wanted to add some hearts. I needed to use a material that won’t become moldy, rusty or break down in the little terrarium eco-system. We used polymer clay and it worked perfectly.
I formed hearts, and inserted bamboo skewers, and baked them according to package directions. They turned out so cute, and I inserted one into each terrarium.
5. Once the inside was finished it was time to put the lid on to create the terrariums own little eco-system, where the water re-circulates.
If you notice condensation on the glass, remove the lid for a couple hours to let the excess water evaporate and then replace it again.
Love Grows Here Label
6. I made a simple heart shaped label with the words, “Love Grows Here”. It’s perfect for my girl’s caring teachers who strive to create a classroom where love grows. I tied them onto the lid with a little ribbon and baker’s twine.
I kind of love them. Hope they bless the teachers in our life. But they’d be there perfect gift for anyone special in your life.
