Pollination Information for American Sentry Linden ( Tilia americana 'McKSentry'):

The American Sentry Linden is a deciduous tree that is known for its fragrant flowers, attractive foliage, and tolerance to urban conditions. The tree produces small, fragrant, and yellow flowers that bloom in mid-to late summer, attracting pollinators such as bees and butterflies. The flowers are hermaphroditic, meaning each flower contains both male and female reproductive organs, allowing for self-pollination.

However, cross-pollination with other American Sentry Linden trees or related species such as Tilia cordata (Littleleaf Linden) or Tilia platyphyllos (Bigleaf Linden) may result in increased fruit production and genetic diversity in the offspring. The tree's fruit, called nutlets, are enclosed in large, papery bracts that ripen in early fall and are dispersed by the wind.

Planting multiple American Sentry Lindens in the same area or near related species can increase the chances of cross-pollination and may help improve the overall health and vigor of the trees. Additionally, providing a diverse range of flowering plants nearby can attract a wider variety of pollinators to the area, further enhancing pollination success.

In summary, American Sentry Linden trees are self-fertile but can benefit from cross-pollination with other Linden species. Planting multiple trees and providing a diverse range of flowering plants can improve overall pollination success and benefit the health and vigor of the trees.

Planting

• Choose a location with well-draining soil and full sun to partial shade
• Dig a hole twice as wide and the same depth as the root ball
• Gently remove the tree from its container and loosen any tangled roots
• Place the tree in the hole, making sure the top of the root ball is level with the ground
• Backfill the hole with soil and water thoroughly
• Mulch around the base of the tree, but keep mulch away from the trunk

Care

• Water regularly, especially during dry spells
• Fertilize in the spring and fall with a balanced, slow-release fertilizer
• Prune in late winter to early spring to remove damaged or crossing branches
• Keep the area around the tree free of weeds and grass, which can compete with the roots for nutrients and water
• Monitor for pests and diseases, and treat as necessary
• Consider staking the tree for the first year to help it establish a strong root system
• Avoid planting near sidewalks or other structures, as the tree's roots can cause damage
• Regularly check for suckers, which can develop from the roots and compete with the tree for nutrients
