When you spend a lot of time working on your garden, having a barrier to keep kids and pets out can help you keep your sanity. A fence or hedge surrounding your garden will do the trick, but you'll also need a gate through which everyone can get in and out. Perhaps one of the simplest ways to erect a garden gate is to use a sheet of lattice, cut to the size of the gate. After that's done, all you need to do is secure the sheet to a sturdy wood frame and secure it to your fence.
Measure the height and width of your gate opening, and then cut your lattice sheet to that size, minus about 1/2 inch on each side. Cutting lattice is pretty tricky, so if you don't have a table saw that will help you hold the sheet level as you cut, have the sheet cut to size at your local hardware store or lumber supplier.
Cut two pieces of wood from the two-by-four, each 1 inch less than the width of your garden gate opening. Then cut two more pieces of two-by-four, each 8 inches less than the gate's desired height.
Lay out the two horizontal and two vertical boards in a rectangular or square shape on the ground or work table. Place them so that the horizontal boards rest over the top and bottom ends of the vertical boards and so that the corners of the boards are flush.
Place a 2-inch metal tie plate at each corner of frame lying on the ground, and drill 1-inch screws through the tie plate to join each board together, resulting in a rectangular or square frame.
Lay the lattice sheet onto the frame, and drill 1-inch screws through the lattice at each corner to secure it to the frame. Then drill more screws every 4 to 6 inches along the frame to further secure it.
Secure gate hinges to the wood frame, several inches from the top and bottom, and then secure the other side of the hinge to the support posts of your fence. On the opposite side of the fence, add a hook or other hardware that will keep the fence closed.
