The Redspire pear tree (Pyrus calleryana Redspire), also known as a callery pear, is native to China. A close relative of the Bradford pear, the Redspire is used in much the same manner, as an ornamental in the residential landscape. The Redspire pear tree produces large white flowers in early spring. The foliage is a reddish-purple upon emergence, turning green with a red cast. In the fall, the foliage turns yellow and orange. The Redspire pear tree will grow to 45 feet tall with a 20-foot spread in a pyramidal shape. The Redspire grows quickly and does not require a lot of maintenance.
Water the young Redspire pear tree so the soil is consistently moist. Although the mature tree thrives in moist soil, it is drought-tolerant and you will only need to water during periods when there is no rain.
Fertilize the Redspire pear tree in early spring, before new growth. Use an all-purpose granular fertilizer, at the rate suggested on the package. Sprinkle the fertilizer on the soil beneath the tree and spread 1 foot beyond the dripzone. Lightly rake it in to the top 1 inch of soil and water to activate it.
Prune the Redspire tree when it is young, to develop a strong structure. Allow only one central trunk to grow by removing any suckers that grow from the lower trunk or the soil. Cut off lateral branches so that those that remain are spaced evenly along the trunk. Older Redspire trees should be pruned every two years to remove vertical branches from within the canopy.
Inspect the Redspire pear tree for pests such as aphids and scale. Aphids can usually be washed off the tree with a strong blast from the hose. Scale may require the use of insecticides. Check with your county cooperative extension agent for recommendations on which insecticides are suitable for your area.
