A table garden is a waist-high planter box on legs; build one with a sturdy frame, deep soil bed, drainage and sun-loving plants.
A table garden brings plants up to a comfortable height so you can sow, weed, and harvest without crouching. It works on patios, balconies, decks, or a corner of the yard where there is no bare ground. With a simple frame, a box on legs, and the right soil mix, you can grow herbs, salad greens, flowers, and compact vegetables within arm’s reach.
What Is A Table Garden?
A table garden is a raised planter that sits on sturdy legs, roughly at waist or hip height. It behaves like a shallow raised bed, only lifted up so you can garden while standing or sitting on a stool. The legs carry the weight of wet soil, while the height suits gardeners with back or knee pain or anyone who prefers an easier working level.
Table Garden Sizes And Uses At A Glance
Before you learn how to build a table garden, it helps to match the size of the planter to your space and your plants. Use the guide below as a starting point, then adjust the exact dimensions to match your lumber and room on the patio.
| Table Size (Length × Width) | Bed Depth | Typical Uses |
|---|---|---|
| 24" × 18" | 6–8" | Herbs, small salad mix, dwarf flowers |
| 36" × 18" | 8–10" | Leafy greens, radishes, compact annuals |
| 48" × 24" | 10–12" | Mixed salad bed, strawberries, bush beans |
| 60" × 24" | 10–12" | Tomatoes in pots set inside, peppers, peas on trellis |
| Square 30" × 30" | 8–10" | Herb collection near the kitchen door |
| Corner L-Shape | 10–12" | Decorative flowers around a seating area |
| Narrow 48" × 12" | 6–8" | Rail-side planter for lettuces and spinach |
Planning Location For Your Table Garden
Location makes or breaks a table garden. Most vegetables and herbs need at least six hours of direct sun each day. Place the planter where it will receive morning and midday light, away from deep shade cast by trees, walls, or balcony railings. Leafy greens cope with a little shade during the hottest part of the day, which keeps them from wilting or turning bitter.
Wet soil is heavy. A medium table planter can easily weigh well over 90 kilograms when filled and watered. Before you start the build, check that your balcony, deck, or paving can carry that load. On upper floors, look for notes in your building rules or ask the building manager. On patios or compacted soil, wide feet or pavers under the legs spread the weight and keep the planter from sinking.
Choosing The Right Height
Many gardeners like a table garden height between 75 and 90 centimetres. Lower than that and you still bend; higher than that and shorter gardeners may struggle to reach the centre of the bed. If you share the planter with family members, aim for a middle height that feels comfortable to all of you.
How To Build A Table Garden Step By Step
Now that the site is set, you can start on how to build a table garden from simple materials. The steps below describe a wooden planter with a rectangular box, four legs, and a slatted base for drainage.
Step 1: Gather Materials And Tools
Use rot resistant timber such as cedar, larch, or treated pine, along with exterior grade screws. Many home gardeners also add a waterproof liner or pond foil to slow rot inside the box. Common tools include a saw, drill or driver, measuring tape, carpenter’s square, and sandpaper. Wear eye and hearing protection while cutting and drilling.
Step 2: Build The Planter Box
Cut side boards and end boards to match your chosen size. Build a simple frame by screwing the boards into a rectangle. Add a rim board along the top edge if you want a tidy finish and a place to rest tools. Check that the box is square by measuring the diagonals; they should match. If they do not, nudge the frame until both measurements match, then tighten the screws.
Step 3: Add A Slatted Base And Liner
Cut several boards or decking strips to span the width of the box. Space them with small gaps so water can drain. Fix them to cleats on the inside of the long sides or directly to the frame. Lay in a sheet of weed barrier fabric or strong weed mat to hold soil while still letting water out. Some builders add a layer of plastic liner against the walls, then punch drainage holes in the bottom so water can leave.
Step 4: Attach The Legs
Cut four sturdy legs from 4×4 posts or doubled 2×4 boards. Screw them securely to the outside of the planter box, flush with the top edge. Cross braces between the legs add strength and reduce wobble. Before you tighten all the fixings, set the planter upright on a flat surface and check that it does not rock. Adjust the legs or plane a little off the feet until the table stands level.
Step 5: Protect The Wood
Seal exposed end grain with an exterior wood sealer or a garden safe finish that resists moisture. Avoid paint or treatments that are not rated for contact with soil or food crops. If you prefer a low maintenance option, you can also base your build on a prefabricated raised planter with legs, then add custom shelves or trim.
Step 6: Fill With Potting Mix
Skip digging soil from the yard. A loose, peat free, soilless mix drains well and stays lighter, which puts less strain on the legs. Research from extension services such as Oregon State University points out that high quality potting media holds moisture while still keeping air around the roots. Mix in slow release organic fertiliser before planting so your crops have steady nutrition.
Table Garden Building Basics For Small Spaces
With the structure finished, turn to what grows inside it. Table gardens behave like large containers, so you can use the same planting rules. Group plants with similar needs for sun and water. Combine shallow rooted herbs and salad greens, or dedicate the whole planter to one crop if you want heavier yields of a favourite vegetable.
Advice on vegetables in containers from the RHS explains that many crops adapt well to container life when given enough depth, drainage, and feeding. Herbs, compact tomatoes, peppers, bush beans, salad mixes, and edible flowers all fit, as long as you match the plant to the available depth and light.
| Plant Type | Suggested Soil Depth | Notes For Table Gardens |
|---|---|---|
| Leafy greens | 6–8" | Grow in bands; pick outer leaves to keep plants going |
| Herbs (basil, parsley, chives) | 6–10" | Keep near the edge for easy snipping near the kitchen |
| Radishes and baby carrots | 8–10" | Use loose soil so roots stay straight and tender |
| Compact tomatoes | 12"+ | Grow one per large corner or in a pot set inside the table |
| Peppers | 10–12" | Need warm conditions and steady moisture |
| Strawberries | 8–10" | Trail over the edges for easy picking |
| Edible flowers | 6–8" | Mix calendula, nasturtium, or violas among your crops |
Ongoing Care For Your Table Garden
Water is the main daily task. Stick a finger into the soil up to the first knuckle; if it feels dry at that depth, water until it runs out of the drainage gaps. In hot spells you may need to water morning and evening. A simple drip line or a watering can kept under the table makes the job quicker.
Feed crops through the season. A slow release fertiliser mixed into the soil at planting time gives a base level of nutrients. On top of that, use a liquid feed every couple of weeks for heavy feeders such as tomatoes. Refresh the top layer of soil each year by scraping away tired mix and adding fresh compost and potting media.
Set a simple reminder on your phone or calendar for watering and feeding. Regular small tasks keep the planter thriving and reduce the chance of pests, wilting, or disappointing harvests through every growing season.
Common Mistakes With Table Gardens
Several small errors tend to show up in first builds. Avoid them and your planter will last longer and grow better crops.
Too Little Drainage
A solid base with no gaps leaves roots standing in water, which leads to rot and fungus. Make sure the base has gaps, the liner lets water through, and the drainage holes stay clear. If water pools on the surface after watering, widen the gaps or add more holes.
Shallow Soil For Deep Rooted Plants
Plants such as tomatoes, peppers, and many ornamentals need deeper soil than a thin table garden bed can offer. Grow these in separate pots set inside the table or choose dwarf, patio, or bush varieties. Reserve shallower zones for herbs, salad greens, and flowers with short root systems.
Overloading The Structure
Long spans of soil without inner braces can bow over time. If you plan a long table garden, add extra legs under the centre or run braces under the base. Regularly check for wobble and fix loose screws before they turn into broken joints.
Once you understand how to build a table garden and how this raised planter behaves through the seasons, you can repeat the design, tweak the size, or add wheels and trellises. The raised height makes gardening kinder on your body, and the compact bed puts a mix of colours, scents, and harvests right where you relax.
