Some Like It Hot!

Except Your Plants

There are two seasons in the Southwest: perfect and really hot. According to the National Weather Service the average temperature in the southwest during the summer is between 103° and 116°. During these extreme temperatures your trees and plants need special attention and protection.

Why, because a plant's temperature usually runs just above air temperature, or higher depending on surrounding factors, such as walls, pavement and asphalt. Like the human body plants “sweat” through a process called transpiration or water loss through the leaves. Simply put, the more evaporation or sweating a plant does the more water it needs. However, watering during the summer is not the only concern.

Using the analogy of the human body again, when the body is under stress it is more likely to be more susceptible to infections and diseases. Extreme temperatures cause trees and plants stress.

An extensive study conducted by The University of Nevada, reports that a single day of extreme heat exposure to flowering plants may be fatal to the reproductive, or gametophytic phase of the plant. A stressed tree or plant is also vulnerable to insects. Like our bodies, the healthier it is the stronger it will be able to fight off potentially deadly invaders.
In order to survive the summer heat, your plants need to “drink” plenty of water; “eat” the right foods; and “wear” the right clothes.

Drink Plenty of Water: Make sure your plants are thoroughly watered. During the summer water will evaporate quickly. Be proactive and do not let your plants or trees dry out completely in between watering, especially during the summer months.

Eat the Right Foods: What is in the soil contributes to the diet of the plant. A healthy pH is vital to the health of your trees and plants. A pH or potential of Hydrogen means the measurement that reveals if a solution is acidic or alkaline. When thinking of acidic, think of lemons and for alkaline think of the slimy feeling of bleach.
A near-neutral or slightly acidic soil is generally considered ideal for most plants. Most soils in the southwest according to The Master Gardner Guide, published by The University of Arizona are alkaline and have a pH of between 7 and 8.5. One of the best ways to keep your soil healthy is to use Moon Valley’s Soil and Water Treatment.

Wear the Right Clothes: During the peak of summer, it would be ineffective and downright silly to keep cool by wearing your winter coat. Likewise, your plants and trees need attire that will promote, not stifle coolness and protection. If possible move potted plants to a shaded area. If this is not possible you can protect your trees by a tree wrap or paint.

A few of the most heat sensitive trees are; Ash varieties, Traditional Fruit Tree varieties, Citrus, and Purple Plums. A Moon Valley Nursery gardening expert will be able to give you more information at 602-938-MOON.
