As a general rule sweet cherries need a pollinizer and most sour cherries are self-fruitful and do not need a pollinizer. Not all sweet cherries can act as a pollinizer so be sure to check what other cherry tree is needed to produce fruit. Pruning every year is also suggested in order to maintain a healthy tree. Pruning should be done in the spring, before the new growth begins. Remove dead or unhealthy branches and limbs. Thin the areas of the tree where the growth is very bushy. Cherries have to be picked ripe. They do not ripen well after they have been picked. There are red, black, yellow and mottled cherries. Recent information about tart or sour cherries show that they have among the highest levels of disease fighting antioxidants compared to other fruits. They are delicious and healthy, a great combination. Our cherry tree offerings are listed below.
