Maximize Growth in Minimal Space: The Ideal Planter Box Depth
Share
You’ve chosen a beautiful cedar planter box. You’re excited to fill it with fresh soil and vibrant plants. But now you’re wondering—how deep should the soil be? Is 10 inches really enough?
At Kelowna Woodcraft, we’ve built our planter boxes with purpose. That 10-inch depth isn’t arbitrary—it’s the result of decades of gardening experience and handcrafted design that brings together form, function, and a little backyard magic.
Let’s dig into why 10 inches is the gold standard for raised planter boxes and how it can lead to healthier plants, less maintenance, and more enjoyment in your garden.
The Root of the Matter: Why Soil Depth Matters
Plants need room to grow—and not just up, but down. Most herbs, flowers, and compact vegetables thrive with 6 to 10 inches of soil. In fact, according to gardening experts like those at Fine Gardening, most leafy greens, shallow-rooted vegetables, and annual flowers do perfectly well in 8 to 12 inches of soil depth.
By offering 10 inches of premium planting space in our handmade cedar planter boxes, we strike the perfect balance for:
- Healthy root development
- Excellent drainage
- Better nutrient access
- Greater control over soil quality
It’s deep enough for most home gardening needs but shallow enough to keep soil cost and weight manageable.
What Can You Grow in 10 Inches of Soil?
You might be surprised by how much fits into a 10" deep planter:
- Lettuce, spinach, arugula, and kale
- Strawberries and herbs like basil, thyme, and parsley
- Zinnias, petunias, and marigolds
- Radishes, green onions, and even carrots
Even compact tomatoes and peppers can thrive in this depth when planted with care and supported properly. Discover more plants that are ideal for container gardening. For deeper-rooted vegetables like potatoes or corn, we recommend a taller garden box such as our 17" x 17" Deep Cedar Planter Box
Why Cedar Makes a Difference
Soil depth is only part of the equation—what you’re planting in matters just as much.
Our cedar planter boxes are handcrafted in British Columbia from sustainably sourced western red cedar. Cedar isn’t just beautiful—it’s naturally rot-resistant, breathable, and safe for growing edibles. Unlike metal or plastic planters, cedar regulates temperature and moisture better, helping plants thrive in all seasons.
And we don’t just build for beauty. Our designs prioritize easy drainage and long-term durability. You can expect your Kelowna Woodcraft planter box to last for many seasons - especially with a bit of seasonal maintenance.
Handcrafted to Grow With You
We believe that great gardening starts with great design. Every Kelowna Woodcraft planter is built by hand using time-honoured joinery techniques and a deep respect for natural materials.
No shortcuts. No synthetic finishes. Just real wood, local craftsmanship, and the promise of quality you can see—and feel—in every garden you grow.
