It’s been a very windy weekend in Tucson. Not only does it make it hard to ride your bike or keep your hair looking nice. It also affects plants.
One of the first things you notice when the wind kicks up if you have allergies is that you start sneezing. The wind has a large effect on allergies. Pollen and mold get blown into the air and moved from place to place by the wind. And, discount cialis this causes allergy symptoms. You may start experiencing a runny nose, viagra sales sneezing and scratchy eyes. And, with dry conditions and wind, hay fever becomes worse. You may even experience a severe allergic reaction like my dog did last week when she broke out in hives after spending time outside in the wind.
A good consequences of the wind is that it helps to strengthen tree trunks and make them more stable. Did you know that when trees sway in the wind their trunks build “taper.” This means that they grow larger on the bottom than at the top of the trunk. This gives you a stronger tree. Trees that have been staked for a long period of time and then taken off their stakes are often weak. These are the trees that blow over in a strong wind.
The wind helps many plant seeds to disburse and this creates new areas where a plant species will grow where it did not grow before. This is great if it’s a beneficial plant that you would like to have in the new area. But, it can be very damaging if it is a weed plant that is spread. One plant that spreads by wind disbursement that we would rather it not spread is Desert Broom. You’ve probably seen the “desert snow” in the Fall when the desert broom pappus and seeds are floating through the Tucson air.
Wind plays an important role in nature in our Tucson desert landscape. It’s amazing how many ways it affects plants. Think about this when you’re outside walking in the wind.
