What Is the Meaning of Drought Tolerance?

Drought-tolerant is the capable feature in which a plant or landscape style can tolerate arid conditions. Being able to conserve your water by minimizing water usage and plants won’t deteriorate because of their ability to thrive in such conditions.

What Makes a Plant Drought Tolerant?

The characteristics that make a plant drought-tolerant are the ability to conserve water and being able to evolve and adapt to dry climates for long periods. These characteristics are split into three different types:

  • Drought Avoidance: This is the ability plants have to store vast amounts of water within their tissue especially when the water content is low in the soil.
  • Drought Tolerance: The ability to adapt to a variety of drought conditions. Either growing thicker or hairy leaves to reflect heat, reducing leaf size to minimize surface area, and deploying xerophytic conditions like reducing the transpiration rate.
  • Desiccation Tolerance: The ability to survive near or extreme points of dehydration. The plants enter a state of anhydrobiosis, which in simpler terms is when the species appears to be dead but once it gains hydration it is then revived in a way.

Difference Between Drought Tolerant & Drought Resistant

The terms drought tolerant and drought resistant are often used interchangeably, and incorrectly so.

Drought-tolerant landscapes can also be referred to as xeriscaping, not to be confused with drought resistance. Xeriscape or xeriscaping is the systemic approach for water conservation usage in plants and design layouts for landscaping. Simply another word for “dry scaping”. When referring to plants that can adapt to these dry conditions, they can be referred to as “xeric” plants.

When it comes to drought resistance, it refers to plants that can thrive without needing water over a long period of time. Very much the opposite when compared to a plant that is adaptable to low-water conditions or standards versus its water retention properties that allows it to survive.
