Help with asian pear trees


#7

Cut those shriveled ones open and see what’s inside if you want to learn more about the problem.


#8

Here’s some pics of the inside of the shriveled baby pears.

I just really like to get these trees back to good health. I have no idea I think some of the leaves look like fire blight but I’m not sure I’m lost


#10

There are several diseases and tiny insects that are troublesome to pear trees and cause damage to leaves and fruit.

However, shriveled young fruit is puzzling. The one cause of this that I’ve read is from fire blight. It is possible that sections of this tree has been attacked by fire blight but not severe enough to kill the tree.

Where in Northeastern this tree is located? Will you be able to post pics of the whole tree or the sections that you think could have fire blight.

Google “Crop Profile, Pears in New York”. It is an article on pear problems from Cornell U. The info is for commercial orchards but home orchards have those same pear problems, too.

Well we are right on lake Erie in ohio so very norther ohio any more north and we would be in the lake.
I Googled what you said and i really don’t know what I think, really there no obvious signs what it is. I may just try to find some kind of anti fungal spray that u can apply now . I’m just not sure. Here are some pics of the whole tree I feel that it is wildly over grown. But I does have alot of fruit on it.


#12

The pictures with holes and claw marks on fruit looks like a bird damage. Some woodpeckers do their holes in a strait line like in your pictures. I do not know if they hunted for water or for the insects inside the fruits.
Also look into the mineral deficiencies. For example boron deficiency. If you soil has basic pH and dry the boron deficiency might happen even if it is boron in the soil. The fruits will have shivered dried patches under the skin like yours have.

When you said you were in "northeastern, I thought you were in New England :grinning:

There are several forum members in the midwest @clarkinks orobably knows more about pears than most of us.

I personalky would not spray fungicide when you don’t know what you spray for. Keep in mind, many pear leave issues are caused by tiny insects that are so small that a magnifying glass is needed to see them. Spraying fungicide for them would be a waste of time and energy.

Also, if the issues are caused by those insects, spraying now could be OK or even too late. Timing of spraying is very important. Read up on those signs and symptoms of pear issues that published by Cornell, Penn State Extension service is a good start. Good luck.

Here is the link to the nice illustration on boron deficiency in pears.

Boron deficiency in pears

They do look like that . At least those two pear look like lack of boron. I’m so new to this lol. All two save two trees my grandmother started lol

Ok guys I habe another question. I watched some videos on fire blight and I’m pretty sure that’s at least one of the problems going on from what I see. They say to prune it out. When should I do this. Honestly the whole thing needs pruned way back regardless do I need to wait till next spring? And in the picture of the tree trunk is there anything I should do with that?


#17

The narrow crotch angle shaped like a v on the trunk is a potential problem for breakage that could damage the tree. The tree is large now and trimming off that large v branch at this point is something I would save for winter. To much disease is active now. The trees have to much competition from other shrubs and trees stealing nutrients around the base which I would eliminate ASAP. The leaves look healthy in the picture. Leaves show no signs of disease and the tree has a good fruit load. Long term the tree is in severe need of pruning. When you prune you lose fruit that year but eventually the shape needs fixed because there are structural problems and you are losing fruits every year due to the shape. A tree can carry much more fruit safely when shaped correctly to distribute weight and encourage fruit set. I would add several inches of aged cow manure and then on top of the manure several inches of wood chips around the base to improve fruit set in a circle at least 6 feet in diameter. The tree has some fruit set now but due to all the things mentioned the tree is struggling. Look for bark lesions on the younger branches as well because we want to rule that out. Here is a list of diseases and the causes of some nutrient disorders https://www.apsnet.org/publications/commonnames/Pages/Pear.aspx. There are some pictures in this 2016 post that will give you an idea of how I shape my Drippin honey Asian pears Here comes the 2016 apple and Pear harvest!. Here are more pictures in this thread Drippin’ Honey Asian Pear. You can see from my Asian pear pictures I grow mine upright but keep the branches evenly distributed as much as possible. There are people who grow there’s very different from mine which is just a matter of preference. I believe in pruning early so I don’t need to prune off as much later.

I really feel like those small shriveled pears comes down to the tree producing what it can support. I do see some pears like that every year. Don’t feel alone on pear problems it happens frequently. This is when I discovered a boron deficiency in my pears Boron deficiency / Blossom Blast?. Note the harvest in the previous post so once the deficiency was corrected I’ve had no more problems at all.


#19

Anybody grow Hamese asian pear. This is its first year fruiting and they are sizing up nicely. But ive always had a problem figuring out when they are ripe. Not sure if it will yellow up or not.


#20

I would eat one every 2 weeks and record the best tasting color or the date of the month.

#21

Tip them up and when the stem breaks off in your hand they are ready.


#22

I picked another Shinseiki today and one of the Hamese. They both came off easily when turning up. In chilling them prior to sampling. Hamese on left, Shinseiki on right


#23

Those look pretty good! Can’t wait to see the taste ratings.


#24

Beautiful. Before you know it, you will be complaining here about thinning pears :grin:


#25

Speedster,
You never said how they tasted. Hope they had a nice flavor.


#26

That Hamese was picked too early and was not very good. I had another Hamese pear that I let ripen longer was much better. It was as good as Shinseiki from what I remember.
