Tall trees are an important, stately element of landscape design. The addition of vertical lighting emphasizes their beauty and presence even more. What is most important is that the lighting be placed at the base of the tree, and not on the tree itself.
Placing vertical lighting at the base of the tree brings out its size and stature without harming the tree in any way. The number of flood lights that you use is dependent upon the size of the tree. As a general rule two or three flood lights should suffice.
Assemble the flood lights. Most flood lights come unassembled, and you will have to attach the base of the floodlight to the garden stake, by inserting the screw and placing the wing-nut on the end of the screw and tightening it. Make sure that the flood light is in the vertical position (so that it can shine upright onto the canopy of the tree).
Position the flood lights evenly around the tree. Stick the stake/flood light into the ground, making sure that the flood light is focused up towards the canopy of the tree.
Determine whether you need to run an extension cord to the flood lights. If your tree is in close proximity to the outdoor outlet you will not need an extension cord. If you need an extension cord -- run it from the outlet to the flood lights, and plug the flood lights into the extension cord.
Plug the flood lights or the extension cord into the outdoor light timer, and plug the outdoor timer into the outdoor electrical outlet.
Test the lights to make sure that they are all working, and then set the timer. View the lights during the evening hours to see the effect that they create in your landscape design
