Callery ‘Redspire’ pears are fast-growing ornamentals with narrow crowns. Read on for additional Redspire pear information as well as tips on Redspire pear tree care.

Redspire Pear Information

‘Redsire’ is an attractive Callery pear cultivar. Its large showy blossoms are larger than other ornamental pear flowers and a dramatic snowy white. Callery ‘Redspire’ pears are deciduous trees, losing their foliage in winter. New leaves grow in a deep purple. They mature to glossy green with a hint of red, then light up your garden in the autumn as they turn yellow, purple and crimson. Fall color is even better in southernmost regions.

If you start growing Redspire pears, you’ll find that the fruits are small pomes, about the size of peas, and reddish-brown in color. This fruit hangs on the tree into winter, serving as food for birds and other wildlife.

These trees shoot up rapidly with a columnar or narrowly-round growth habit. They can get to 40 feet (12 m.) tall with a spread up to 20 feet (6 m.). The branches on Callery ‘Redspire’ pears grow out and up. They are completely thornless and never droop or dip at the tips.

How to Grow a Redspire Pear Tree

The trees thrive in U.S. Department of Agriculture plant hardiness zones 5 through 9a. When you start growing Redspire pears, select a planting location that gets full sun for best results. This cultivar accepts many different kinds of soil, everything from sand to clay. It will grow in acidic or alkaline soil and tolerates both wet and well-drained soil.

Since the tree is so tolerant about site location, you’ll find that its maintenance is mostly a matter of after-planting care. Although the tree’s drought tolerance is high once its root system is established, you’ll want to provide generous irrigation until that time.

Pruning may be an essential part of Redspire pear tree care. Trim out branches with weak crotch connections to help the tree develop a strong structure.

Callery ‘Redspire’ pears have pretty good resistance to fire blight, oak root fungus, and verticillium. They can be susceptible to whitefly and sooty mold, however.

Strong wind broke off large branch on Redspire pear tree

The break is not clean and some bark around the break peeled away. I do not want to loose this tree.
How to I treat this ?

You could take some pictures of the tree and its wound, and post them here. That would help contributors here give good advice.

Having worked around thousands of these Callery Pear cultivars over my career, I have seen this kind of damage innumerable times. It is an expected consequence of growing this species of tree. "I do not want to lose this tree" may not be an outcome over which you have any control. It is kind of like saying "I don't want my kids to grow up." It inevitably happens, despite efforts to the contrary.

Providing your tree with standard healthy conditions is likely the best course of action. Water during droughty periods, provide balanced fertilizer (after a soil test) if there are nutrients lacking mulch to protect trunk from lawn management equipment. You could pay a certified arborist to inspect your tree, offer opinions like these presented, and do corrective pruning to additional poor branching characteristics.

Without seeing or knowing any more than I do now, I suggest that you plan for a new tree to succeed your Redspire Callery Pear. IMO, there are hundreds of better selections than Pyrus calleryana and I hope you invest in one of them if/when your Redspire retires.

OK tomorrow, during daylight, I will get a photo and post here.
Thank you.

ps I did not want my children to grow up . . but they are wonderful adults now and I struggle w/ how fast my grandchildren are growing up.

I inherited a 30 year old Bradford pear that was interfering with power lines and, better yet, displaying the usual narrow crotches and to top that, the beginnings of rot. I brought in an arborist and he suggested that I COULD keep the tree for a few more years but when it split it would not be pretty, and since pruning it to get it away from power lines was expensive I just had them remove it, grind the mulch and leave it, and put in an acer griseum a few feet from the original site.

That is certainly one way to go about it, Donna - and probably the wisest choice given your circumstances. It isn't the only way, for sure.

Around here - and most of the eastern US - this species is seeding itself prolifically into natural or unmanaged landscapes, and is rapidly being considered the latest invasive species. "The Coming Plague of Pears" is one moniker bandied about. I don't know whether this is yet the case in Washington state, but I won't be surprised when I do hear that happening. This is another reason to plan for its passing, and invest in the future otherwise.

The economics made sense, because pruning it would have cost about two thirds of the cost of removing it - and the power line issue was going to arise again within five years. And, frankly, I was very eager to install an acer griseum, since I had one before. The pear dropped all kinds of nasty fruit that I could never get out of the sidewalk. And I had rejected pears in my previous landscape. Imagine how pleased I was when I asked for a suggestion for a replacement and his first suggestion was a paperbark maple - it's one of my favorite trees. And, VV, you will be pleased, I think, to know that the removal of the pear created enough sun and space to put in 3 of the viburnums from Classic Viburnums - two compact carlesis and a dentatum 'Chicago Lustre'. And underneath the acer griseum I added some old garden roses I had been coveting and did not have room for previously.

I learned, years ago when you lose a plant, it sometimes presents an opportunity to put in something that suits you just as well, if not better.

Here are photo's of damage.

i would leave the scar as is - tree should be fine - until it drops a few more branches

People here are trying to be so kind, but the underlying message they're sending is that this tree is an invasive pest in much of the US. Most here would never be so rude as to impune one's character, but this tree has a tawdry reputation. I have no idea if Pyrus calleryana is invasive in your area, and in no way trying to tell you what to do, but if your climate is anything like its Canadian namesake, this might be a good time to consider something else. If you really want to get us excited, just ask us for a few trees you might consider to replace it.

Character is like a tree and reputation like a shadow. The shadow is what we think of it the tree is the real thing.

Vancouver, WA (a suburb of Portland, Oregon) is a lovely spot, especially now when the beautiful pears and cherries are in bloom. I love the tree shape and the blooms on the pears, but as you have found the branches are brittle-see my link about it, so you may be able to save the tree but be ready for more branch breakage now that they are big and heavy.

The first thing my husband said after sawing off the broken branch "all of the wood is brittle".
I knew there were issues w/ Bradford Pears but assumed the Redspire was better. We took out a thorny Hawthorn & local nursery recommended this tree about 10 yrs ago.

I like the size and shape so looking for a replacement that is fast growing w/ same size/shape.

Landscape Uses and Considerations

Fruitless pears are shallow-rooted and will tolerate most soil types. They are also resistant to pollution, making them ideal ornamental plantings for urban landscapes, advises Missouri Botanical Garden. Preferred in home landscapes for their tidy shape and glossy, deep green leaves, fruitless pear trees typically reach a mature height of between 30 and 50 feet.

Most fruitless pear trees produce no fruit, but some may produce inconsequential fruits, about 1/2-inch in diameter, which are eaten by birds. Fruitless pear trees are commonly planted in home landscapes for screening, shade and to attract birds.

Flowering Pear Tree Longevity

If you love your flowering pear tree, you will surely think that the tree's life span is too short. On the other hand, those who consider flowering pear trees to be invasive think that they live entirely too long. However, the actual life span of the tree in years appears to be a matter of contention.

According to the Cal Poly Urban Forest Ecosystems Institute, the longevity of ornamental pear trees ranges from 50 to 150 years. However, this is not the consensus.

Experts at Clemson Cooperative Extension put the life span of the Bradford cultivar at only 15 to 25 years, and the experts at Yale Nature Walk agree with the lower number, putting the maximum longevity for the Callery pear tree at 25 years. They add that Callery ornamental pear trees usually die even earlier given environmental issues.
