This year I tried an experiment growing improved Kieffer Pears spray free. So what were the results? No insect damage, no disease, 3 damaged fruits with 1 1/2 5 gallon bucket harvest on a small tree. I won’t tell anyone these are perfect pears or that they are 100% grit free. The reason why I did this experiment was to demonstrate the hardiness of this variety to those wanting an easy pear tree to grow. Pick the pears as soon as they will easily pull from the tree with no effort and let them ripen inside.
Here is a description from Trees of antiquity
" American heirloom pears are extremely rare so the Kieffer pear tree is a special treat. In 1853, Peter Kieffer planted a small nursery in near Philadelphia where he grew imported Chinese Sand Pear seed. Kieffer also grew Bartlett pears. So one day he noticed a seedling with unusual foliage so he saved it. Kieffer is a high quality pear ideal for fresh eating, pear honey and preserves. The Kieffer pears are golden yellow skin blushed with crimson envelops crisp, juicy, coarse-textured white flesh with musky aroma. Hardy, vigorous tree bears young with dependable crops. Perfect variety for southern states as it tolerates hot climates and is practically immune to fireblight. The Kieffer pear tree fruit is best harvested while still hard and store in a cool place; reaches peak flavor when fruit gives slightly to the touch.
