Detailed explanation-1: -Use a layer of organic mulch on the surface of your planting beds to minimize weed growth that competes for water. Organic mulch helps reduce evaporation and saves hundreds of gallons of water a year. Spreading a layer of organic mulch around plants helps them retain moisture, saving water, time and money.

Detailed explanation-2: -The short of it is that your plants need more water in extreme heat, but it’s not just the amount of water that matters. Plants also need water to be applied in the most beneficial way.

Detailed explanation-3: -Oxygen and water vapor exit the leaves through stomata, as well. In many plants, when the outside temperature is warm and water evaporates more readily, plants close their stomata to prevent excessive water loss.

Detailed explanation-4: -Water your plants in the morning as early as possible. This allows the soil and your plants to absorb more water because in the heat of the day there is more evaporation occurring at the soil surface.
