How to Build a Wooden Potting Caddy with Compartments for Hand Tools

A wooden potting caddy keeps the hand tools you use most within reach instead of scattered across a bench or buried in a shed. This version has three compartments: a large center bin for gloves and plant labels, plus two narrower side sections for trowels, pruners, dibbers, and a small brush. It is a straightforward beginner woodworking project that can be built in an afternoon with inexpensive pine.

Design and Materials

The finished caddy is approximately 18 inches long, 9 inches wide, and 8 inches high, not including the handle. Those dimensions hold several hand tools without becoming awkward to carry. Adjust the length if your potting bench is small, but avoid making the box much deeper than 9 inches; tools tend to disappear in a deep container.

Clear pine is easy to cut and relatively cheap. Cedar costs more but resists occasional moisture better and is less likely to swell at the joints. Avoid construction lumber with pronounced twist or large knots, especially for the bottom. A small woodworking clamp set is useful, but you can manage this project with two inexpensive clamps and careful screw placement.

Cut List

Cut the pieces to these dimensions:

• Bottom: one piece, 18 by 9 inches
• Long sides: two pieces, 18 by 7 1/4 inches
• End panels: two pieces, 7 1/2 by 9 inches
• Dividers: two pieces, 7 1/4 by 8 1/4 inches
• Handle: one piece, 18 by 1 1/2 inches

The 7 1/4-inch side height leaves the dividers slightly below the top edge, so smaller items can be removed without fighting the divider. The end panels are taller because they cover the ends of the side panels. If your lumber measures slightly differently, keep the bottom at 18 by 9 inches and measure the end panels between the long sides rather than relying blindly on the list.

Prepare the Parts

Sand the cut edges with 80-grit paper, then smooth them with 120-grit. Round over the top edges with sandpaper. A sharp corner is uncomfortable when the caddy is lifted, and rough edges catch gloves and sleeves.

Mark the divider locations on the bottom panel. For two equal side compartments, place the dividers approximately 5 1/2 inches from each end. Check the actual width of your tools before fixing this layout. If your pruners have wide handles, make one compartment 6 1/2 inches wide and reduce the other. The center compartment should be large enough for gloves, plant ties, and a small container of labels.

Pre-drill every screw hole near an edge. Pine splits easily, particularly when screws are driven within 3/4 inch of an end. A wood drill bit set with a bit slightly smaller than the screw shank is sufficient. Countersinking is optional, but it prevents screw heads from snagging your hands.

Assemble the Caddy

Start by attaching the two long sides to the bottom. Apply a thin glue bead along the bottom edge of each side, align the edges flush, and drive screws every 5 to 6 inches. Use a square at both ends before tightening the screws. Too much glue is a mistake here: squeeze-out is harder to remove after it dries and can interfere with the end panels.

Fit the end panels between the long sides. Glue and screw them to the bottom and side panels. The box should be square before the glue sets. Measure diagonally from corner to corner in both directions; the two measurements should be within about 1/8 inch. If one is longer, push that corner inward before adding the final screws.

Install the dividers next. Apply glue to their bottom and end edges, position them on your marks, and screw through the bottom. Use one screw near each end and another in the middle. Do not rely on glue alone. Soil grit and repeated lifting put stress on the divider joints, and a loose divider quickly becomes an irritating rattle.

Center the handle across the end panels and mark its position. A handle mounted about 1 1/2 inches below the top edge gives enough clearance for your fingers. Drill pilot holes through the handle into both end panels, then drive two screws at each end. If the caddy will carry wet soil or heavy pots, use a thicker handle, such as a 1-by-2, rather than the listed 1-by-1 1/2 piece.

Finish and Weatherproof the Wood

Break all remaining sharp edges with 120-grit paper and remove the dust. For a caddy used under cover, two coats of exterior water-based polyurethane are adequate. For a caddy left in a greenhouse or exposed porch, use an exterior penetrating oil or exterior paint on every surface, including the bottom and end grain.

Let the finish dry fully before loading tools. A cheap finish is fine if you store the caddy indoors between uses. The failure mode to avoid is sealing only the visible outside: moisture enters through the uncoated bottom and end grain, causing cupped boards and loose screws. Add small rubber or plastic feet if the caddy will sit on wet concrete.

Seasonal Use and Upgrades

Build it in late winter before seed-starting begins, when the tools are easy to inventory. In spring, keep the center compartment for labels and transplanting supplies. During summer, reserve one side for pruners and harvest scissors. In fall, the caddy can hold bulb-planting tools and gloves, but brush off damp soil before storage.

A removable divider is a useful upgrade if your tool collection changes. Instead of gluing that divider, attach two narrow cleats to the bottom and slide the divider between them. This is less rigid and can rattle, but it lets you reconfigure the compartments. You can also drill a 1-inch drainage hole in the bottom, though that makes the caddy unsuitable for loose labels and small packets unless you add a liner.

For a basic tool carrier, skip decorative trim and expensive hardwood. Spend the money on straight boards, exterior glue, and a finish that matches where the caddy will live. The result will be lighter, easier to repair, and more practical than a heavily ornamented box.
