Cat Grass DIY Concrete Planter

The other day I saw a sign that said, “Plant ladies are the new cat ladies,” and had a little laugh, but then I started thinking to myself that I’m both. As far as blog projects are concerned, though, you’d think my plants get all of the love. You might get the impression that I never make anything for my cats, which isn’t true. The scratching posts I’ve made them just aren’t the most photogenic pieces. To combine my love for cats and plants into one project, when I was making my gold and concrete plant pots, I poured this DIY concrete planter for growing cat grass.

This is Adventurous, the only one of our two cats who eats grass. She loves to munch on grass so much that we refer to her as a little sheep. (She has a GPS tracker on her neck, if you’re wondering about that. She lives up to her name.)

I made this planter the exact same way as the plant pots, with Quikrete, but I used a plastic box from salad greens as the outer mold, and an oxyclean detergent container for the inner shape.

The clear plastic that salad greens come in was the perfect shape, but it’s pretty flimsy, so I had to use pieces of wood to keep it from bowing out at the sides. If you want to use a greens container as your mold, keep in mind that any ridges or shapes in the plastic will transfer. If you want a plain one, you might have to do a bit of searching in the produce aisle.

Fresh out of the mold! I let it cure for a few days before I planted in it.

I planted it with cat grass seeds (oats), which only take a few days to grow to edible length.

I like how modern and sleek it is, and it’s so heavy and low that I don’t have any worries about it getting tipped over. I used to occasionally buy a plastic container of cat grass from the grocery store, and Adventurous would knock it over while grazing. Problem solved!

  1. I really like your concrete cat grass planter. In the past I’ve used pieces of nylon stocking or knee-hi’s for cat grass. I just put planting mix and the seeds into it, tie the ends and water. The grass grows out of the stocking but there’s no way the cat can dig in the dirt. They could tip the pot over though. I could put that right into this planter and it would stay put. Thank you so much for the idea!

    • Larraine, how smart to use the stockings to prevent digging! Combined with the concrete, it sounds like we can thoroughly cat-proof our planters, until the cats figure out new ways to make trouble 🙂

      • There’s always another way. They still surprise me occasionally after many years. You have so many wonderful ideas that I will be checking back regularly. Thank you
