I would love to make suggestions, but sense both Ayers and Warren have too high of chilling requirement to ever bloom where I am, I can’t say for certain what will bloom with them. I’ve heard lots of anecdotal comments about how both Ayers and Warren are weak pollenizers. Anyway check and make sure you get enough chilling hours in your area. I believe Ayers requires over 600 hours and Warren requires 800 hours. About the most I can count on getting is around 500 hours. Talk to someone who has both and make sure they bloom together. In my opinion, it would be hard for someone in the Deep South to do better than to plant LeConte and Goldenboy. Both are fireblight resistant. Both are mid season bloomers for a southern pear. Both are fairly early ripening, July here in SE Georgia 9a. The only commercial source for Goldenboy that I know of is Just Fruits and Exotics. I know that their LeConte is the original high quality one with good fire blight resistance. There is an impostor out there sold under the LeConte name that lacs the latter’s table quality as well as its fire blight resistance.
Baldwin and Acre’s Home are go really well together. Both are early blooming and are a bit more vulnerable to getting yacked by frost on account of it. Baldwin is a semisoft pear with good flavor and fabulous canning qualities. It’s my absolute best canning pear. It’s my bosses favorite pear for salads because it’s so sweet and juicy, has just the right crunch and does not brown quickly. The pears ripen in late July or early August here, bout a week after Goldenboy which is about a week after LeConte. Acre’s Home originated from a community in Houston TX by that name. It has won one over nearly every other southern pear in flavor reviews. It’s a huge, very juicy pear. It’s probably too soft for my liking when fully soft ripe, but mine rarely make it that far. Another one which many people absolutely love but is too soft for me is Southern Bartlett. That one has to be fruit thinned or it will over crop and then skip a year. However, as long as you fruit thin, it’s a super polliniizer in so far as it has its main bloom early in the season and then a new cluster of flowers will arise out of the original ones and bloom mid season. That second batch of flowers only set fruit if that early batch gets yacked by frost, but it will pollenize mid season bloomers like Goldenboy and LeConte even though those two show every sign of being self fertile.
The last two I will mention are Tennosui and Scarlett. Tennosui originated from Texas as well and is a hybrid between Tennessee and Hosui. It supposedly has the fruit charactoristics of Hosui but without the fireblight. Mine bloomed for the first time this year, so I can’t comment on fruit, but it blooms a bit too late to be pollenized by LeConte, Goldenboy or Orient for that matter, but blooms too early to be pollenized by Asian pears like Korean Giant and Shinko. My hunch is that it would make a good pollenizer for either Ayers or Warren. But what I know blooms with it are Scarlett and Savannah. As with Tennessui, it’s the first year those trees have bloomed, so I can’t talk about fruit quality first hand.
Last comment. Just because a nursery in your area h as a given variety in stock, that does not mean that it will work. They get what they can get from whole sellers, and most nurseries haven’t got a clue what they are doing when it comes to fruit trees. But before spending money on a Warren pear, make darn sure that you can count on 800 chilling hours every year. Good luck.
