Pollination Information for Dakota Pinnacle Birch (Betula platyphylla 'Fargo')

Dakota Pinnacle Birch is a deciduous tree that produces both male and female flowers in the form of catkins. The male catkins are long and droopy, while the female catkins are smaller and upright.

Pollination occurs through wind-dispersed pollen. The male catkins release pollen into the air, which is carried by the wind to the female catkins. The female flowers then receive the pollen and begin to develop seeds.

It is important to note that cross-pollination is preferred for optimal seed production in Dakota Pinnacle Birch. This means that the tree will produce more and better-quality seed if there are other birch trees of a different variety nearby to provide pollen. However, Dakota Pinnacle Birch can also self-pollinate if no other birch trees are nearby.

In summary, Dakota Pinnacle Birch is pollinated by wind-dispersed pollen and can self-pollinate if necessary. Cross-pollination with other birch trees is preferred for optimal seed production.

• Dig a hole that is two to three times wider than the root ball, but no deeper than the root ball height.
• Carefully remove the Dakota Pinnacle Birch from its container or burlap, and gently loosen any tangled roots.
• Place the tree in the hole, making sure to keep the top of the root ball level with the soil surface.
• Backfill the hole with soil, gently tamping it down to remove air pockets.
• Water the tree thoroughly to help settle the soil and remove any air pockets.
• Mulch around the base of the tree, but do not let the mulch touch the trunk.

Caring for Dakota Pinnacle Birch

• Water the tree deeply once a week, or more often during hot, dry weather.
• Fertilize the tree in early spring before new growth appears, using a balanced fertilizer formulated for trees.
• Prune the tree in late winter or early spring to remove any dead or damaged branches, or to shape the tree as desired.
• Monitor the tree for pests and diseases, such as bronze birch borer, and treat as needed.
• Protect the tree from damage caused by lawn mowers or weed whackers by creating a mulch circle or physical barrier around the base of the tree.
• Do not plant other trees or shrubs within 10 feet of the Dakota Pinnacle Birch, as it is susceptible to root competition.
