The Japanese maple (Acer palmatum) is known for its small, delicate leaves with pointy lobes that spread outward like fingers on a palm. These leaves turn fabulous shades of orange, red or purple in autumn. These trees can tolerate shade but hot, full sun can reportedly lessen their lifespan. If you want to enhance the lifespan of Japanese maple trees, give them regular irrigation, provide an annual application of good quality compost, and install them in a location that provides partial shade and good drainage. Also, make sure the planting hole is scarified so the new roots can penetrate into the native soil and that there is some drip irrigation at the outer edge of the planting hole so the roots are encouraged to move outward.
