The cedar tree is a coniferous genus of the pine tree family. Cedar species include the atlas, Cyprus and deodar, along with several others. Cedar trees have a natural pyramidal shape with a symmetrical canopy. A cedar tree can reach a height up to 60 feet tall with a spread half its height. These easily grown trees are cold hardy, drought tolerant and require very little care after the first year.
Keep the area under the cedar tree free from of debris and invasive weeds. Hand-pull weeds from the area as they appear, making sure to remove the entire root system with the flower. Protect the area from weed invasion by spreading a 2- to 3-inch layer of organic mulch around the base of the tree.
Irrigate the tree thoroughly throughout its first three to four years. Provide the tree with approximately 1 to 2 inches of water using a slow irrigation process. Irrigate the tree thoroughly and infrequently to avoid overwatering. Adjust irrigation levels during long periods of rain.
Feed the cedar tree with one pound of fertilizer per inch of trunk diameter. Use a well-balanced, slow release fertilizer. Distribute the fertilizer evenly under the canopy of the tree out to the drip line. Keep fertilizer approximately one foot from the base of the tree to prevent root burn. Select fertilizer combinations such as 20-20-20 or 40-40-40.
Inspect the cedar tree regularly for signs of disease. Look for wilted or browning foliage, excessive defoliation, rusting or mildew. Treat disease symptoms immediately. Use a copper-based fungicidal spray to control disease.
Prune away any dead, dying or diseased areas from the tree. Use sharp, sterile pruning shears and sterilize the shears between each cut. Discard any diseased clippings immediately. Do not use for organic mulch or compost.
