You can pick your own fresh ripe delicious cherries from your own home-grown, backyard cherry tree, and you can expect that your tree will produce easy-to-pick clusters of cherries in colors of yellow, red and black on semi-dwarf trees. Not only is the color of cherries important to most cherry growers, but some cherries are sour to the taste and others are sweet. The montmorency, red sour cherry is a very important canning cherry that is used for baking cherry pies. The sour cherry tree is generally more cold hardy than the sweet cherry tree, but the sour cherries' pollination requirements are less complicated than the sweet cherry trees. Producing cherries from the home garden means that the crop must mature during a very short growing season, and unlike growing most fruit trees, that short growing season causes them to be very expensive at the grocery store. The deep red color of the red sour cherry, such as the montmorency, results from the anthocyanin pigmented chemicals that have lately been reported to fight cancer and tumors. Sweet cherries such as the Bing cherry is in great demand at the commercially grocery store market for fresh eating, however, the shelf life of sweet cherries is very limited, even with cold storage treatment. Eating fresh cherries has been demonstrated to be an effective treatment for the onset of the gout disease.
