Answer: Both your apple and pear trees will need a second apple and pear variety for pollination. Most pear varieties are self-unfruitful. However, nearly all pears are suitable pollinizers for other varieties that bloom at the same time. One exception is Seckel, which is not a good pollinizer for Bartlett. Even though Anjou, Bartlett and Kieffer are partially self-fruitful, they should be cross-pollinated to produce heavy and regular crops. Pear flowers produce only a small amount of nectar, which is low in sugar. For this reason, more pollinizers and bees are needed for pears than for any other tree fruit.
Although some apple varieties, such as Lodi, Liberty, Empire, Winesap, Jonathan, Jonagold, Gala, Golden Delicious, Rome and Granny Smith may be listed as self-fruitful, they will set more fruit on an annual basis if they are cross-pollinated. Additionally, some apple varieties, such as Winesap, Stayman, Mutsu and Jonagold, produce sterile pollen and therefore cannot be used to pollinate other apple varieties.
So, the first thing you need to do is find a compatible pollinzer for each of your new fruit trees. Then, to have healthy trees, you'll need to put them on a spray schedule. Here's a webpage that you can print off so you'll know what to spray and when:
Best wishes with your trees!
