A wooden harvest tray is useful for carrying tomatoes, beans, peppers, herbs, and cut flowers from the garden without crushing them in a bucket. This version has a solid bottom, low side handles, and slats in the sides for airflow. It is simple enough for a beginner, but the dimensions and joinery are sturdy enough for a full load of produce.

Project overview
The finished tray is approximately 24 inches long, 14 inches wide, and 6 inches high. That gives you enough room for a useful harvest while keeping the tray manageable when it is full. Expect a loaded weight of 15 to 20 pounds, depending on the crop and wood used.
| Material | Advantages | Drawbacks |
|---|---|---|
| Cedar | Light, naturally weather resistant, easy to work | Soft and prone to dents; costs more |
| Pine | Cheap, widely available, easy to cut | Needs a good finish and can warp |
| Exterior plywood | Stable bottom panel and economical | Edges need sealing; avoid interior-grade plywood |
Cedar is the best all-around choice if the tray will live outdoors. Pine is perfectly suitable for occasional garden use, especially if it is kept under cover. For the bottom, choose 1/2-inch exterior plywood or straight 1×6 boards. Avoid pressure-treated lumber where produce will touch it.
For the fasteners, use stainless steel wood screws. Galvanized screws are cheaper and acceptable for a budget build, but stainless steel will not leave rust marks after repeated washing.
Materials and tools
You will need two 1×6 boards, 24 inches long, for the long sides; two 1×6 boards, 13 inches long, for the end assemblies; four 1×2 boards, 13 inches long, for the vertical end slats; and one 1/2-inch plywood panel, 23 by 13 inches, for the bottom. You will also need four 1×2 cleats, each 21 inches long, to support the bottom, plus two handle pieces approximately 1×3 by 14 inches.
Use a tape measure, pencil, square, drill, countersink bit, and saw. A random-orbit sander makes the work quicker, but sanding blocks are enough. A 5-inch random-orbit sander is a sensible purchase if you expect to build more than one garden project. For this tray, do not buy a large professional machine just for the job.
Cut and prepare the parts
Cut all parts accurately and mark the outside face of each piece. Small differences are manageable, but an end panel that is 1/4 inch out of square will make the tray rack. Check every cut with a square.
Sand the faces with 120-grit paper, then soften every exposed edge with 180-grit paper. Pay special attention to the top edges and handle openings. A sharp corner is uncomfortable to carry and can split when the tray is dropped.
If your lumber is rough or slightly damp, let it acclimate in a dry place for several days before assembly. Wet lumber can shrink around the screws and leave loose joints. Do not use boards with deep end checks, major knots at screw locations, or visible twist.
Build the end assemblies
Each end consists of a 13-inch-wide lower end board, two vertical 1×2 slats, and one 14-inch handle above them. Position the slats 1 inch in from each side. Set their bottom ends flush with the bottom of the end board, then leave a 2-inch gap between the slats.
Drill 1/8-inch pilot holes before driving screws. Use two 1 1/4-inch screws through each slat into the end board. Add the handle across the top, centered from side to side, with its lower edge about 1/2 inch above the slat tops. Use two screws at each end of the handle.
That handle arrangement creates a broad handhold rather than a narrow finger hole. If you prefer a cutout handle, use a jigsaw to make a rounded opening at least 4 inches wide and 1 1/2 inches high. Leave at least 2 inches of wood above the opening and 2 inches at each side. Smaller or sharper openings become uncomfortable under load.
Assemble the tray
Stand the two end assemblies upright and place the long side boards between them. The side boards should cover the end-board edges, producing an outside length of 24 inches. Clamp one side in place, check that the corners are square, and drive two screws through each side board into each end assembly.
Repeat for the other side. Measure diagonally across the top corners. If the two diagonal measurements differ by more than 1/8 inch, push the tray into square before tightening the screws.
Install the four bottom cleats inside the tray, 1/2 inch above the lower edges. Place one cleat against each end assembly and one along the inside of each long side. Pre-drill and use 1-inch screws so the screw tips do not break through the outside surfaces.
Drop the plywood bottom onto the cleats. It should fit without force; trim it if necessary. Screw it down with 1-inch screws spaced every 6 inches. Do not glue the bottom. A removable or lightly fastened bottom is easier to replace after years of wet use.
Add slatted ventilation
The gaps between the end slats provide ventilation, but the long sides are mostly solid. For better airflow, drill six 3/4-inch holes along each long side, centered vertically and spaced about 3 inches apart. Keep the first and last holes at least 2 inches from the corners.
For a more traditional look, replace the solid side boards with three 1×3 slats per side, leaving 1/2-inch gaps between them. This is lighter and vents produce better, but it allows small items such as beans or cherry tomatoes to roll out. Solid sides with drilled holes are the safer choice for mixed harvests.
Finish and maintenance
Sand the complete tray with 180-grit paper. Round the top edges and inspect for screw points, splinters, and rough spots inside the tray. Wash the wood dust off with a damp cloth and let it dry fully.
For a food-contact surface, use a food-safe wood finish such as a cutting-board oil or wax. It will not make the tray waterproof, but it slows staining and makes cleaning easier. Exterior water-based finishes offer better weather resistance, but confirm that the product is rated for incidental food contact and allow it to cure completely before use.
Never store wet produce in the tray overnight. Empty it promptly, brush off soil, and wash it with mild soapy water when needed. Stand it on edge to dry. If the plywood bottom swells or the screws loosen, remove the damaged panel and replace it rather than trying to seal over the problem. For regular heavy harvesting, keep a second tray available so one can dry while the other is in use.
