Best budget planter boxes
Updated June 2026Independently researchedNo paid placement.
The Milanese 24x18x12 cedar planter with self-watering is our top budget pick for its compact size and built-in reservoir.
The Gardener’s Supply Company 36-inch cedar raised bed on wheels is the best runner-up for anyone who needs to move their planter around a patio or balcony.
Raised planter boxes let you grow vegetables, herbs, and flowers even on a small patio without digging into the ground. A good budget model combines durable materials, decent drainage, and enough depth for healthy roots, ideally without costing a small fortune. When choosing, look at the size (width and depth matter more than height for most plants), whether it has a self-watering system or wheels, and the type of wood or composite. Cedar is naturally rot-resistant and lightweight, which is perfect for moving around. Budget planter boxes under a certain price point often skimp on wood thickness or lack features like a water reservoir or casters. The two picks here balance affordability with real-world usability: the Milanese option offers a compact self-watering design for tight spaces, while the Gardener’s Supply model adds portability with its built-in wheels. Both are well-reviewed by owners and experts, and both should last a few seasons with basic care.

Best for small patio spaces
If your outdoor area is limited to a narrow balcony or a corner of a small deck, the Milanese 24x18x12 cedar planter is the clear pick. Its compact footprint leaves room for a chair or two, and the integrated self-watering reservoir cuts down on the frequency of watering, a real bonus when floor space is precious.

Best for gardeners who chase the sun
For anyone who needs to move their plants to follow sunlight or avoid wind, the Gardener’s Supply 36-inch cedar raised bed on wheels is the top choice.

It’s especially handy for renters who don’t want a permanent raised bed that damages the surface. Our pick: Gardener’s Supply Company 36-Inch Cedar Raised Bed on Wheels.
Best for growing a mix of vegetables and herbs
When you want a single planter that can hold several types of plants, the Gardener’s Supply 36-inch model offers enough length to separate tomatoes from basil and lettuce. The extra depth compared to the Milanese (36 inches long but similar depth) gives roots more room, though it lacks a water reservoir. For a versatile, portable vegetable patch on a patio, this rolling bed is hard to beat. Our pick: Gardener’s Supply Company 36-Inch Cedar Raised Bed on Wheels.
Our verdict
Both of these budget-friendly raised planter boxes deliver real value without breaking the bank. The Milanese cedar planter wins for small spaces and lazy-watering convenience, while the Gardener’s Supply rolling bed is the better choice if you need portability or want to grow a wider variety of plants. Think about your patio size and how much you want to water, then pick the one that fits your daily routine. Neither will disappoint for the price.
