Dakota Pinnacle Birch – Caring and Propagation tips 2022

Dakota pinnacle birch is considered one of the hardest birch available in the market. It is also known as the Japanese white birch.

These trees were first discovered growing near Dakota state university’s arboretum in Absaraka. Boe, a scientist working in the university, collected the seed from the tree growing near his workplace and planted it in the university’s campus located in Fargo.

These seedlings were kept under observation for many years; however, in the year 1989, the seedling was seen to be growing in size. After observing for three more years, it was propagated by the grafting and tissue culture method.

These trees were named ‘Fargo’ after several hardinesses and bore resistance tests which later changed to ‘Dakota Pinnacle Birch’.

Pruning

Pruning is not mandatory for this tree. It can be trimmed occasionally for shaping purposes, but it is advised that you prune it in the summer season as spring season pruning can cause the tree to bleed sap.

Water requirements

Watering should be done on a daily basis in the hotter zones, while the requirements decrease as you move towards the cooler areas of the world. The roots must be kept moist in order to keep the tree hydrated and healthy.

Fertilizer

It does not require a lot of feeding to grow well; however, a tree fertilizer can be used in the spring season to maximize the tree’s growth rate.

Propagating Dakota Pinnacle Birch

Dakota Pinnacle Birch can be propagated with tissue culture, soft woodcutting, or grafting. To propagate the tree with the softwood cutting method, you should follow the steps below in a sequence to ensure proper tree propagation.

  • Choose a branch that is younger than the rest; these branches are often called softwoods or semi-ripe as they can bend easily.
  • After choosing the most flexible branch, cut about 3 to 4 leaf nodes. Make sure that the leave nodes are about 6 to 8 inches long.
  • Take a sharp pruning pear and cut under the leaf node less than .25 inches below.
  • Remove the leaves from the bottom, leaving only the ones at the top of the branch.
  • Keep the cut covered by a plastic bag with moisture in it, as drying them out can decrease the chance of success drastically.
  • Treat the cutting with a rooting hormone.
  • Take equal sand and peat moss concentrations in a pot and wet the mixture.
  • Plant the cuttings in the mixture after making a hole of about 3 inches depth.
  • Make sure that you keep the soil moist to maximize the success rate.
