Cherries

6 cherry trees:

  • 3 Van

  • 3 Bing

Cherry trees grow well in Newfoundland, and are a popular selection at the nursery. Consequently, we were very lucky to get 6 cherry trees, all just in from the mainland. They had already flowered, and without fruit this year. These trees were much easier to plant since they arrived in peat pots instead of plastic. Dig hole, pop in ground.

As with the other trees, we needed more than one variety of cherry for pollination. Both Van and Bing cherries are big purple fruit, sweet and tasty when ripened.

Our six trees are at the farthest back end of the rink, nearest the bonfire pit. They are closer together at 15' apart than the other tree types, and must shorter. While they are the least hardened to our environment, they appear sturdiest with lush green foliage located in the rockiest part. Their early spring flowers will make a lovely backdrop to the rink in the spring -- I hope!

Biggest concern for the cherry trees is ensuring snow mobiles and quads can see them and stay clear. There is an old trail behind the rink and bonfire pit, so we're moving rocks to create a barrier. If you see a rock, carry it back!

We also need to watch for any sign of black knot. Native cherry trees can catch it. From the Planet Natural Research Center:

Black knot is a widespread fungal disease that attacks plum and cherry trees, both fruiting and ornamental. The fungus, Apiosporina morbosa, (also identified as Dibotryon morbosum and Plowrightia morbsum), singles out trees of the genus prunus, which includes peach, apricot, and chokecherry. Once established, black knot is easily identified with its hard, uneven, black galls that seem to enwrap twigs and branches. Black knot is a slow developer, taking a season before it’s visually apparent and producing spores. The trick to controlling the fungus is identifying the infection well-before the disease becomes firmly established. If left to grow, it effectively strangles new growth, girdling branches and dooming the tree to deterioration and poor fruit production. Insects and plant diseases use the galls as an entry to the tree.

Tart cherry varieties are said to be less susceptible to the disease than sweet. Japanese plums are said to be less susceptible than American varieties. A number of plums, including President, Early Italian, Santa Rosa and Shiro carry varying degrees of resistance to the fungus.
