Willow Oak Tree (Quercus phellos) Pollination Information:

The Willow Oak tree is monoecious, meaning it has separate male (catkins) and female (flowers) reproductive structures on the same tree. The male catkins produce vast amounts of pollen that is wind-dispersed. This means that insects are not as critical in the pollination process for this species as compared to insect-pollinated plants. Once the pollen lands on the female flowers' stigma, the pollen tube travels down to fertilize the ovule.

As the tree gets older and reaches maturity (around 20-25 years of age), it will produce heavier fruit crops. These acorns will not develop unless pollination has occurred, making pollination critical for successful reproduction. The tree must receive enough pollen for proper fertilization of its flowers and development of the fruit. Up to 20% of flowers may reach full development into acorns.

Overall, the Willow Oak tree relies heavily on wind pollination to successfully reproduce and maintain the species.

• Dig a hole that is three times wider than the width of the tree's root ball and as deep as the root ball.
• Place the tree in the hole and fill with soil while gently tamping down around the base.
• Water the tree thoroughly after planting.

Care Requirements:

• Water the Willow Oak regularly, especially during periods of drought.
• Fertilize in early spring to encourage healthy growth.
• Prune the tree in late winter or early spring to remove dead or damaged branches.
• Apply a layer of mulch around the base of the tree to retain moisture and prevent weed growth.
