How to Make Concrete Flower Pots Using Silicone Flowerpot Molds?
Oct 08, 2024| This DIY combines some of my favorite things, concrete crafting and plants. Using Silicone Flowerpot Molds that set quickly, I wanted to make a few small flowerpots for my house as I have some plants that can be grown in the pots. Not sure why concrete makes great flowerpots? I wrote an article about the pros and cons of concrete as a flowerpot.
The DIY is pretty simple, all you need is concrete, water, and a silicone flowerpot mold. Basically, anything can be turned into a mold, but remember that if it's not silicone or rubber, it will end up being ruined. Also keep in mind the size, concrete flowerpots can get heavy quickly.
Tips and Tricks
Always wash the silicone flowerpot molds before using them. If you're using plastic, it may be difficult to cut it out of the pot once you're done, so you can wipe the inside with Vaseline before pouring in the concrete.
If you don't want to deal with that, use cardboard! You just cut the pieces and tape them together, making sure the edges are completely sealed, and then when the concrete is dry, you can tear off the cardboard. Either way, we're recycling, which is always beneficial!
Suppose you have a Silicone Flowerpot Mold. They come in lots of fun shapes and sizes, and some have drainage holes built into them.
Getting Started
Quick-Setting Concrete
Two mold containers
Disposable mixing cup
Something to mix with (chopsticks)
Mixing Concrete
Spoon dry concrete into the cup and slowly add water as you mix. The instructions for my concrete said 5 1/2 parts concrete to 1 part water, but I think I used closer to 2 parts water.
Mixing Concrete
The consistency of the concrete should be as follows after mixing. It should be similar to pancake batter.
Pour Into Silicone Flowerpot Molds
Pour the concrete into the larger container, filling it about two-thirds full. Press the smaller container into the mixture and the concrete should rise to the top. Let dry for 24 hours.
Peel the mold off the concrete. You can loosen the top edge with needle-nosed pliers, then slowly pull it down until it's all the way out. Now we're going to put the soil and plants in.
This DIY is so easy! For my next concrete planter, I will explore painting the concrete, putting something in it (maybe wood?), and making a drainage hole in it.
