They sure both look Asian to me. I think you should maybe replace both with trees properly identified, but because they are probably Asian they will probably adequately identify themselves very shortly. If they are Asian you don't have to worry about speeding their fruiting- they may even bear next season. The reason I would consider replacing them is because fireblight can be heartbreaking and even if you graft on other varieties the trees may be susceptible unless you have no tender new wood from original trees. On the bright side, many Asians are fireblight resistant. Multiple leader pear trees are common in commercial production in the west coast. Here in the east they are mostly grown to a central leader- I guess we don't get quite as much FB. Festooning (pulling branches below horizontal)the branches may encourage early fruiting but it will not encourage a great scaffold structure. I sometimes use the method for trees I plan to train to a weep or for Euro plums just to get them into fruiting mode but many types of pears should not be trained this way in my opinion. None of the Asians I grow would be good candidates for this, they fruit so early anyway. Asian and European pears are mostly pollen compatible- the problem can be timing of bloom. That issue will sort itself out as well when trees begin to flower.

Clare, thats a tough call. I have found pears difficult to get into a vase shape. It varies by variety, some work well but many just want to go up up up and a great deal of spreading is needed to get a vase. I didn't have the time to spread them properly so I now have some half pyramid half vase trees (double or triple leader) which are working OK. If I were starting over I would consider just doing pyramid shapes. If you are up to the time investment in spreading, completely remove the leader now and start working on a vase shape. The one pruning I would do on your pear now is to head it back so its height is limited. Unless you want a big tree. It will grow a new leader anyway. Scott

It can be done but Asian pears bear young from new trees. You might gain a yr or two on the production curve. If you need exercise and enjoy the challenge go for it. But a bare root planted this fall or next spring will be easier and considerably less work. You'll need to water that big tree regularly next summer to gain much.
