Grow an open-air pavilion. Four plum trees define the rustic backyard getaway atop pea gravel. As they fill in, the trees’ twining branches will supply foliage to cover the supports. In three to five years, after the branches intertwine sufficiently, you’ll be able to remove the stakes and supports.
Mow a 6×6-foot grassy area very short. Plant a young, 9-foot-tall plum tree at each of the four corners. Place gray landscape cloth over the square and cover it with pea gravel a few inches thick
Prune the lower branches. Pound a 9-foot red-oak stake about a foot into the ground next to each of the four trees. Using 6-foot lengths of bamboo, form two 6×6-foot squares, lashing the corners of each square together with twine.
Insert a 2-1/2-inch galvanized decking screw about 3/4-inch into the outside of each oak stake, 11 inches below the top. Slide one bamboo square over the stakes so it rests on the screws.
Insert a 2-1/2-inch galvanized decking screw about 3/4-inch into the outside of each oak stake, 3 inches below the top. Slide the other bamboo square over the stakes so it rests on the top set of screws. To secure the squares, lash the bamboo to the stakes.
Remove all but the top four branches of each tree. For each tree, bend two of the top four branches to the left. Use twine to tie one branch to the top bamboo support and the other to the bottom support.
Bend the remaining two branches of each tree to the right, using twine to tie them to the squares in the same way as in Step 3.
