The Gardener’s Supply Self-Watering Elevated Cedar Planter is a premium raised-bed solution designed for urban gardeners, patio growers, and anyone looking for a more ergonomic approach to growing vegetables and herbs. This product merges elevated gardening with self-watering convenience, offering a blend of natural aesthetics and engineered functionality. In this expert review, we dissect its components, assembly, maintenance requirements, and optimization techniques while comparing it to similar products on the market.
Tools Required for Assembly
- Cordless drill (optional for faster assembly)
- Rubber mallet
- Level
- Screwdriver
- Wrench (included)
- Garden hose or watering can for reservoir test
Material and Design Specifications
Constructed from sustainably harvested cedar, this elevated planter naturally resists rot and insect damage. The planter box stands at waist height, reducing strain during planting and harvesting. Integrated into its base is a polypropylene self-watering reservoir with a capillary mat that draws water upward as needed. The corners are reinforced with powder-coated aluminum brackets, increasing structural stability and weather resistance.
The cedar boards are untreated, which maintains organic gardening integrity but requires seasonal oiling or sealing to prolong life. The slatted bottom allows excess water to escape, protecting plant roots from oversaturation.
Assembly and Setup Instructions
Assembly is intuitive but benefits from two people for alignment and lifting. Begin by laying out all components and confirming the parts list. Fasten side panels using the included brackets, ensuring right angles are square with a level. Install the slatted floor base, ensuring it aligns flush with the side walls.
Once the frame is assembled, position the internal water reservoir and place the capillary mat on top. Fill the reservoir and check for leaks. Capillary action should begin within 30 minutes. Insert the fill tube, ensuring the overflow outlet is unblocked.
Site selection is critical. The planter should be placed on a level surface with ample sun exposure. Avoid areas prone to strong wind unless anchoring is planned.
Soil Filling and Planting Considerations
Use a high-quality raised-bed mix blended with compost for optimal results. The planter holds approximately 1.4 cubic feet of soil. Avoid overly dense soil as it impedes capillary action. Amend with perlite or coconut coir if needed to increase porosity.
Prioritize shallow-root crops such as lettuces, herbs, spinach, and strawberries. While deeper-rooted plants like tomatoes are possible, they may require additional trellising or root zone adjustments.
Routine Maintenance and Seasonal Care
To maintain performance, clean the capillary mat and reservoir at the end of each growing season. Flush the reservoir with diluted vinegar to remove mineral buildup. Allow all components to dry thoroughly before reassembling.
Apply a natural wood sealant once annually to prevent cracking or discoloration. Inspect corner brackets for rust or loosening; tighten or replace hardware as needed.
Refresh soil annually by removing the top third and replacing it with new compost or soil mix. For year-round use, add a hoop cover or cold frame to extend the growing season.
Troubleshooting Common Issues
Some users report water not reaching the upper soil layer. This is typically due to improper reservoir priming or compacted soil. Rewet the capillary mat and mix in more porous material to remedy the issue.
Warping of the cedar panels can occur in humid or rainy climates. Regular sealing reduces this risk. Panels that swell or contract excessively may need re-fastening or bracket adjustment.
Pest intrusion, while rare due to elevation, can happen with slugs or ants. Use diatomaceous earth or install copper tape along the legs as a deterrent.
Customization and Productivity Enhancements
For water efficiency, consider adding a rain barrel system connected to the fill tube. This allows automatic topping up during rainy periods.
Boost yields with vertical gardening attachments like a trellis for peas or cucumbers. Plan for companion planting by using a grid layout—basil with tomatoes or radishes with lettuce to maximize space and natural pest control.
Add a shade cloth during peak summer months to protect leafy greens from bolting. Mesh pest covers can be clipped onto the rim for added protection without restricting sunlight.
Comparative Analysis with Similar Raised-Bed Systems
Compared to the VegTrug Elevated Planter, the Gardener’s Supply model offers superior water management due to its integrated reservoir. The VegTrug, while larger, lacks a built-in self-watering system, requiring more frequent manual watering.
When placed beside galvanized steel beds such as the Vego Garden system, the cedar design is more aesthetically pleasing for patio settings and better for growers avoiding synthetic coatings. However, Vego systems provide greater modularity.
In terms of ergonomics, this planter outperforms ground-level beds and non-elevated options, especially for older gardeners or those with limited mobility.
Add-On Compatibility and Accessory Integration
This raised bed is fully compatible with Gardener’s Supply accessories including mesh pest covers, greenhouse frames, and micro-drip irrigation kits. The planter’s rim allows secure clipping of hoop-house rods or netting frames.
The fill tube can be adapted with a float valve connected to a low-pressure irrigation reservoir for semi-automated watering. Shade cloths can be fastened to the frame using standard clips or hook-and-loop wraps.
FAQs
1. How often should I fill the water reservoir?
Typically, every 7–10 days, depending on weather and crop density. In hot climates, check twice weekly.
2. Can I grow tomatoes in this planter?
Yes, but use compact or determinate varieties and add a sturdy trellis for support.
3. Does cedar leach harmful substances into the soil?
No. Untreated cedar is naturally safe for organic gardening and poses no toxicity risk.
4. Is the capillary mat replaceable?
Yes. Replacement mats are available through Gardener’s Supply or can be cut from bulk felt material.
5. Can I use standard potting mix?
Potting mix can work if amended with compost and perlite for better structure and water movement.
6. Will it survive winter outdoors?
Yes, but draining the reservoir and covering the bed during freeze periods is advised to prevent cracking.
Conclusion
The Gardener’s Supply Self-Watering Elevated Cedar Planter is a well-engineered solution for small-space and patio gardeners who prioritize ease, efficiency, and aesthetics. While the price point may be higher than some alternatives, its integrated reservoir, ergonomic height, and durable materials justify the investment for serious growers. When properly maintained and paired with the right accessories, this planter delivers consistent yields, reduced labor, and long-term gardening satisfaction.
