Tongue-and-groove cedar creates a stronger planter wall.

Drainage without liners

A precision-slotted base allows water to exit while oxygen enters, supporting healthier roots.

Frequently Asked Questions

Which raised bed size is best for most gardeners: 44×18, 72×24, or 18×48?

For most gardeners, 72×24 tends to deliver the best reach-to-yield balance. It provides more planting area and spacing flexibility while still staying reachable for planting and harvesting.

Is 44×18 big enough to grow vegetables?

Yes. A 44×18 footprint is great for herbs, greens, peppers, and compact veggie mixes—especially when you want a smaller bed that’s easy to manage and maintain.

Does a 72×24 bed produce more than an 18×48 bed?

Often, yes—because the extra width supports better spacing, root room, and crop layout flexibility. Yield depends on sunlight, soil, and planting plan, but the 72×24 layout is typically easier to optimize.

Which size is easiest to reach across?

44×18 is the easiest to reach across. 72×24 is still very comfortable for most gardeners and is often considered a “sweet spot” for elevated beds.

Do elevated planters improve drainage and root health?

They can—especially when the base is designed for natural drainage and airflow (no plastic liner). Better airflow at the root zone helps reduce soggy soil and supports healthier root structure.

Does metal hardware or legs affect soil temperature?

Metal can conduct heat faster than wood, which may increase temperature swings near contact points in direct sun. Material choice and support design matter most in hot climates.

How do I choose the right bed if I’m torn between sizes?

Start with your layout and reach. Choose the largest size you can comfortably access from the sides, then pick the height you’ll enjoy using weekly—comfort and consistency usually drive better harvests.
