Cedars are virtually disease and pest resistant. Cedars look great as a single specimen, planted in clusters to create privacy or in containers. They are the number one choice for an evergreen hedge.

Cedar Care
They prefer well drained soil and full sun to part shade. They grow well in full sun but tend to have a more open and ratty appearance when grown in shade.
Fertilize your cedar hedge in the early spring when flowers and plants are blooming. Refrain from fertilizing the hedge in late summer, as the hedge will require rest for dormancy during the winter.

Flowers
Arborvitae are monoecious have separate sexes on the same plant. The male flowers are yellow and drop off in the spring. Female flowers are greenish and they are the ones that produce cones. Sometimes you will find plants with lots of cones. It could be that the plant just has an overabundance of female flowers or sometimes it is a sign of plant stress.

Pruning
Cedar hedges won’t need to be pruned the first year or when they are under 3 feet. As hedges mature, start pruning your cedar hedge in early spring. Use the shortest plant as a guide, and trim off tops to match, then do a light trim on the sides. If your goal is to encourage more height, do not trim the the leader, or topmost shoot. Just prune a few inches of growth to encourage both height and fullness.  Avoid pruning in temperatures above 30 degrees Celsius. To keep plants healthy, never cut more than one-third of the plant in one season.
