A trellis assists in providing a substantial structure for vining plants such as roses, clematis, honeysuckle, jasmine and wisteria. Trellis structures are available as simple wood lattice and squares, or ornately decorated plastic, metal or long-weathering wood such as teak and mahogany. Gardeners who wish to secure the trellis against sag under heavy loads or displacement by strong winds and lawn equipment may prefer to take steps to fasten the trellis to the house.
Procure two pieces of 2-inch by 4-inch lumber measuring the width of your trellis. If the trellis tapers to a wider width at bottom or top, take this into consideration when cutting the wood.
Measure and mark the wall surface where the blocks of wood will attach to the wall. Hold the trellis against the wall to ascertain the area where you want to mount the trellis, and in turn where to affix the lumber to the wall so as to hit the trellis in the correct spot when you later attach it to the lumber.
Apply a ¼-inch-thick line of construction adhesive to the back of the two 2-by-4 pieces of lumber. This adhesive is available under several brand names available at your local hardware or general department store. It may be purchased in a squeeze tube or caulk-gun-style tube and may be referred to as polyurethane adhesive.
Press the lumber pieces against the wall and hold in place until the wood remains by attached without assistance. With name-brand construction adhesives, you will usually have about 10 to 30 minutes of workable time before it starts making a permanent bond with the brick. You may want to use pieces of lumbar or long tool handles to brace the wood in place until it the adhesive is dry.
Allow adhesion to dry thoroughly which could range from 8 to 12 hours to overnight if you prefer to split the project into two work sessions. Test for a complete bond and then you may wish to seal or paint the lumber to match your house or trellis.
Hold the trellis in place and screw in the four wood screws using the electric screwdriver or drill with a screw driver bit inserted into the area where a drill bit attaches. A regular manual hand tool screw driver will suffice. Start with the left upper side of the trellis and begin turning the screw in a clockwise direction to the right. Insert the screw until it is completely driven into the 2-by-4 on the wall, and the flat screw head is flush with the trellis surface.
Check and adjust the trellis to make sure it is still in its correct position, and then continue inserting the screws starting with the upper right and then continuing with the two bottom screws in the exact same manner as you screwed in the first one.
Tug lightly to test for strength, and hold, to be sure the trellis is attached permanently and withstand the weight of the vines you will be growing up its surface.
