How to Make an Easy DIY Rock Cactus

9 Materials
1 Hour

A few years ago I made a super easy DIY rock cactus. It turned out really cute and best part—cost me nothing because I had all supplies already on hand.

I gathered my supplies

– 5-10 larger river rocks

– Green acrylic paint (2-3 different shades)

– Paint brushes

– White Sharpie paint marker

– Plant pot

– Handful of used plastic grocery sacks (not shown)

– Small river rock


– Faux pink flower(s)

– Hot glue gun


– Pink acrylic paint and a faux flower in any color

I started by painting the rocks with two quick coats of the green paint (my toddler even got into the action). I decided to do three different cactus “plants” at the same time, so you might need to paint more or less rocks depending on how many plants you wanna make.

I did most of them in a solid color, but decided to paint stripes on a couple. I even got my kiddo involved.

Once the rocks were dry I laid them all out together and then started to divide them up into different DIY rock cactus “plants”.

I took my white sharpie pen and drew some cactus-like patterns on them. Stars and polka dots seemed to work best for me.

Once the white paint quickly dried, I took my pots and stuffed the bottoms with handfuls of plastic grocery bags.

This fills up the space and lets you get away with only using a handful of small river rock on the tops in each pot. It also keeps the cactus lightweight.

I began to layer the rocks into the pots until I was happy with their placement.

Then I painted a taped off section of the pot.

I decided that the simple single cactus needed a pink flower and that the both pots needed a paint dipped look, so I painted a two faux flowers that I found around the house pink and taped off the pots and painted them as well.

I repeated these steps on a couple other cactus pots....

And this is how they turned out.

What do you think? Will you give it a try? The results are super cute.

I have mine placed in my  home office nook, and they bring a pop of color to my day.
