Dieback from Kabatina blight appears in early spring, from Phomopsis in summer. Small lesions may be seen at the base of dead tissue. The diseases may progress down the stem killing the whole branch. Twig blights cause death and browning of twigs tips. Mites cause stippled and bronzed foliage. The larvae are often in the densest part of the plant and can go unnoticed. The larva is 1/2-inch-long and is brown with darker stripes. The Juniper webworm webs twigs and needles together, causing them to brown and die. The scale is round and at first white, later turning gray or black. Juniper scale causes yellowed needles, and infected branches fail to produce new growth. The insects can also be picked off the plants by hand.
The insects live in the bags and emerge to feed on the foliage. Pestsīagworm caterpillars occasionally web foliage and debris together to make bags up to two inches long. Some nurseries carry a cultivar or two of redcedar.Ĭultivars include: 'Burkii' - pyramidal, blue foliage, 15 to 25 feet tall 'Canaertii' - compact, pyramidal, good fruit production, fairly common in Texas 'Hillspire' - (cupressifolia) - good green color 'Elegantissima' - Goldtip Redcedar - branchlets with yellow tips, less than 20 feet tall 'Filifera' - pyramidal, branchlets divided, foliage gray green 'Glauca' - Silver Redcedar - narrow, columnar, 15 to 20 feet tall, silvery blue foliage especially in spring 'Ketlerii' is commonly available in the mid-west, is more open with spaces between branches at the top of the tree, pyramidal 'Manhattan Blue' - compact, 20 feet tall, pyramidal, foliage bluish green 'Pendula' - Weeping Redcedar - branchlets pendulous, to 40 feet tall 'Pyramidalis Dundee' - pyramidal, purplish green in winter. There may be local restrictions on planting this tree near apple orchards because it is the alternate host for cedar-apple rust.

Usually insects and diseases are not a problem if grown in the full sun. It performs admirably with no care, even on alkaline soil and along the coast. Water until well-established and then forget about the tree.
Plants are difficult to transplant due to a coarse root system, except when quite small. Growth will be poor in landscapes which are over-irrigated. Planted in full sun or partial shade, Eastern redcedar will easily grow on a variety of soils, including clay, but will not do well on soils kept continually moist. The fragrant wood is popular for repelling insects. Its high salt-tolerance makes it ideal for seaside locations.
It can be used as a garden accent or specimen in a ground cover bed.
The narrow crown would call for close spacing for a screen planting. The dense growth and attractive foliage make Eastern redcedar a favorite for windbreaks, screens, and wildlife-cover for large-scale landscapes.
