Cedar trees are types of evergreen known for their aromatic wood, thickly cracked bark, soft needles and pendulous branches. Cedars are common in many regions of the world. They are hardy in temperate zones and do well in climates that do not experience winter weather below -10 degrees Fahrenheit and grow well in a variety of soil conditions. Additionally, they do not require full sun, which makes them well suited to a wide range of climates. These qualities, combined with ease of long-term care, have helped to make the cedar a popular tree to plant and grow.
Water the tree once it has been planted. For the first four weeks, check the new tree daily and add water as needed. The goal here is to keep the surrounding soil moist, but not soggy or muddy. Try to avoid watering to the point of leaving standing water around the base of the tree. Too much water will cause the roots to rot.
Spread a 3-inch layer of mulch in an 18-inch circle around the base of the tree each spring and again in the fall. Use tree bark, cocoa hulls or other biodegradable material rather than plastic sheeting or rocks. As the mulch breaks down it will add organic material, enriching the soil.
Sprinkle slow-release granular fertilizer beneath the tree every fall for the first three years after planting. Spread the fertilizer in an even layer until it reaches 18 inches beyond the ends of the branches. Do not allow the fertilizer to come into contact with the trunk of the tree as this can cause a chemical burn.
Remove any vegetation which may sprout up from the area around the base of the newly planted tree. Grasses and weeds will compete with the cedar sapling for resources needed for successful growth. Pull them out by hand to prevent disturbing the young tree's root system.
Prune the tree each spring, cutting away any broken branches or areas of obvious damage. Cedars tend to reproduce in mid-summer. Once you see buds developing on the branches, stop pruning.
