If you're looking to elevate your outdoor space, there's a simple, foolproof way to create beautiful potted plants: The "thriller, filler, spiller" formula.
Casey Finn of The DIY Playbook invited Tanja Babich to her own backyard to show us how.
Secret to a Perfect Pot
The "thriller, filler, spiller" method is all about balance, texture, and visual interest:
Thriller: A tall, eye-catching plant that adds height (placed in the back or center)
Filler: Mid-size plants that add color and fullness
Spiller: Trailing plants that spill over the edge
What You'll Need
Planter with a drainage hole
Potting soil
Thriller plant (height)
Filler plants (color)
Spiller plants (for the edge)
Gardening gloves
Small shovel
Step-by-Step: How to Build the Perfect Pot
Step 1: Add Soil
Fill your planter with potting soil, leaving a few inches of space at the top.
Tip: You can place empty plastic containers at the bottom of the pot to reduce the amount of soil needed and keep it lighter.
Step 2: Arrange Before You Plant
Place your plants - still in their containers - on top of the soil to map out your design:
-Thriller in the back or center
-Fillers around it
-Spillers near the edge
This helps you visualize the final look before committing.
Step 3: Plant + Pack
Here's the trick that makes it foolproof: Remove plants from containers, but place containers back in the pot and fill the pot with soil.
Remove containers and add plants to the holes.
Step 4: Water Thoroughly
Once everything is planted, Give everything a deep soak.to help it settle and thrive.
