When we think of a tree blooming, our first thoughts are trees with bright flowers on them: magnolia trees, crepe myrtles, or desert willows. But every tree in the world blooms, even the ones that we don’t think of as flowering trees. The mighty oak is an excellent example of this. If oak trees didn’t bloom, we wouldn’t have more oaks.
What Does It Mean for a Tree To Bloom?
Understanding when oak trees bloom requires an understanding of blooming itself. When you think of a bloom, don’t just think of purple, pink, or white blossoms. Think of a growth on a plant that serves the primary function of reproduction. These are the places where pollination occurs and where seeds and fruit grow later.
What Do Oak Blooms Look Like?
As with other creatures, plant reproduction involves both “male” and “female” parts. On oak trees, the male and female parts exist as two different blooms that grow on the same branch. These branches, called oak catkins, look like little light green or yellow tassels. The male blooms grow as the tassels themselves, while the female blooms grow on the husks where the acorns develop.
When Do Oak Trees Bloom?
Since blooms are a plant’s means of reproducing, it makes sense that they would choose to bloom when the weather is warm enough that the new blooms will be safe. In other words, most plants bloom in the spring. Most oak varieties bloom between March and May. Red oak tree varieties tend to bloom several weeks before white oak varieties.
Although the primary factor influencing when oak trees bloom is the length of the days, other factors may cause a tree to bloom later. These may include:
- Soil Nutrients
Damage to a tree’s root system will also impact the volume of blooms that appear on a tree. Surprisingly, trees with damaged roots often produce more blooms, not fewer, as they attempt to prolong their lineage.
