The Jonamac apple variety is known for its crisp, flavorful fruit and its tolerance of extreme cold. It is a very good apple tree to grow in cold climates. Keep reading to learn more about Jonamac apple care and growing requirements for Jonamac apple trees.
What is a Jonamac Apple?
First introduced in 1944 by Roger D. Way of the New York State Agricultural Experiment Station, the Jonamac apple variety is a cross between Jonathan and McIntosh apples. It is extremely cold hardy, able to withstand temperatures as low as -50 degrees F. (-46 C.). It is because of this, it is a favorite among apple growers in the far north.
The trees are medium in size and growth rate, usually reaching 12 to 25 feet (4-8 m.) in height, with a spread of 15 to 25 feet (5-8 m.). The apples themselves are medium in size and usually slightly irregular in shape. They are deep red in color, with a little bit of green showing through from underneath.
They have a firm texture and a crisp, sharp, pleasant flavor very similar to that of a McIntosh. The apples can be harvested in early autumn and store very well. Due to their crisp flavor, they are used almost exclusively as eating apples and are rarely seen in desserts.
Growing Requirements for Jonamac Apple Trees
Jonamac apple care is relatively easy. The trees rarely need winter protection, and they are somewhat resistant to cedar apple rust.
While they prefer well-draining, moist soil and full sunlight, they will tolerate some drought and some shade. They can grow in a range of pH levels too.
In order to get the best fruit production and to avoid the spread of apple scab, to which it is somewhat susceptible, the apple tree should be pruned vigorously. This will allow sunlight to reach all parts of the branches.
