What do trees have to do with hurricane preparedness? A LOT!
Shape – Size – Support - Saturation
Shape: When trees grow in nature, in a forest, they are surrounded by other trees. Because the only light that hits the tree is on the top of its structure, the tree develops a canopy shape. This shape minimizes the amount of weight that the tree has to support because the growth pattern is pushing limbs and leaves up not out.
Trees that grow in our yards are referred to as “specimen trees” because there is usually only one or two of them together. Since the trees in our yards are not surrounded by other trees, sunlight hits them from many directions and sides. This encourages broad spreading limbs and makes for a very pretty rounded tree shape. It also encourages more weight to grow away from the trunk and central support system.
Size: We like to fertilize and encourage our trees to grow. Big healthy trees look nice! But they also grab more wind. In nature, in the forest, the competition for sunlight causes trees to develop a more wind resistant profile. They cram all of their leaves into the areas where sunlight falls, mainly along their roof or canopy. In our yards, trees leaf out all over and since the light filters all the way through the tree it becomes a large sail in the wind with leaves through out its structure.
Support: The intertwining of roots in the ground and upper limbs of the canopy give even the largest trees a support structure anchoring the top and bottom of the tree for support. This allows a tree in the forest to take advantage of its neighbor and lean on them for support. Pine trees are especially noted for this characteristic. In our yard though, most of our trees stand alone with no neighbor to lean on.
Saturation: We all water our grass, but do we water our trees? You might think you do, but I’ll bet the answer is “no.” The deepest grass roots are less than six inches below the surface of the soil. This is the area of the soil that is loose and easily broken. Trees need roots that go deeper into the more compact layers of soil. Our yard trees that have been watered when we watered the grass will grow shallow roots in the weak layer of soil.
What to do? How do you keep your trees safe in a Hurricane?
The best care we can give our trees to prepare them for a hurricane is easy. All it takes is some routine maintenance once a month or so.
- Regularly (once to twice a year depending on the tree) prune the tree to reduce the weight and keep it from growing a top heavy structure. This will help with both Shape and Size!
- Plant them in clumps of three or more when possible. This will allow the trees to structurally lock together and improve Support.
- And encourage deep root growth by watering slowly for a long time. The best way is through a drip watering system or through a soaker hose that runs for long periods of time. Soil Saturation develops deep roots that hold your trees in place.
We can’t prevent another storm from blowing over our favorite tree, or landing a pine tree in our front dining room, but we can make our trees stronger and less likely to topple in a strong wind.
