I have tasted and love the Honsui Asian Pear. In searching the forums here to see if it is a good fit to easily grow in my coastal influenced SW WA climate, I found only one reference to problems with Pseudomonas in the Vancouver WA area. Do others have this problem, or are there some productive trees bearing fruit in this area? Maybe too many questions here, but can this be controlled by summer (dry weather) pruning? Lastly, would the problem be better or worse, closer to the coast where the temps are a bit more moderate, but maybe slightly damper. To rephrase the last question, which has the most influence, temperatures or rainfall?

That should be Hosui. Sorry!

I grow many types of Asian pears on one tree. They have few disease problems, but I do need to protect them from codling moth. I prefer the footies on them with Surround, because the baggies largely flew off in windstorms last Spring.

What varieties do you have John? is one of them Hosui?

I don't . I have Shinseiki, Don Bae/Korean Giant, Chojuro, Ya Li, and 20th Century. The first three are fruiting, but I look forward to the others fruiting soon.

This is not an answer you are exactly going to like, but plant it. It might work out, or it might not, at which point you remove it and try something else. But at least then you would know and would have had a few fruits to enjoy (in theory). I know that can be frustrating, waiting for second tree to grow in, but if you have your heart set on something, give it a try unless you have strong evidence not to.

I have never heard of Asian pears doing poorly in our climate, and I've heard of many that grow them successfully. I agree with candlepdx: plant it. You may find that you need to prune it a lot, put organic material in the sandy soil, or make sure it is in 100% full sun. You can move a tree. I've moved dozens of them. I have many trees in which I love the fruit, and I never would have known. I have no memory of regretting planting a tree that I liked. Go for it!

They do get Pseudomonas, till well established (7 + years). Cut off dead shoots, treat ends with copper. Spray tree several times with Cuprofix or other copper sprays.

They tried it in Georgia but it was not ok because of heat and humidity.

A really nice guy from Tennessee mailed me some scions of a variety called "Tennosui". I think it is a seedling of Hosui in Tennessee that has some different characteristics. It took and seems to be growing well. I have since noted that some of the now 6 varieties on my tree have varying slight signs of disease pressure: small dots, etc. We have had a dreadful, drippy spring, but it seems to be drying out now. I look forward to tasting it, so I would try the Hosui. I have put ziploc bags and footie sox on them because they can easily be nailed by the codling moth here.

Because the pear tree variety named 'Tennessee' had good disease resistance in the Houston area, but lacked a super quality fruit, an experimental mass seed planting was done with Tennessee seeds in hopes of possibly finding a better fruit. Of those seeds that became trees, there were 2 that produced quality fruit and retained good disease resistance. One had pale green skin, was medium size, sweet, crispy, and in general looked like a European pear. It was given the name Southern King. I enjoyed sampling the fruit from this seedling and have 5 branches growing here after doing bark grafts with some of it's twigs last August. The other winner from the mass seed planting was given the 'hybrid' name Tennosui because the seed came from the variety 'Tennessee', but the features of it's fruit are very much Asian like a 'Hosui' tree in the same orchard. Obviously, the bees transferred Hosui pollen to a Tennessee flower, which became a fruit whose seeds were planted. I also sampled fruit from this tree (with permission) and really liked it. The crispy, white, sweet,apple shaped,medium sized fruit are covered with a slightly thick, yellow/tan, blemish free skin. The disease resistance is good. There are now many Tennosui branches growing on several pear trees here that were in need of upgrading. If pear growers there wanted to graft Tennosui scions to trees that are actively growing new leaves, bark grafts could be done with budwood that is still dormant in the fridge here. Let me know if you want any.
