Choose the Best Time for Watering the Garden

With water restrictions becoming an increasingly common part of life in many parts of the world, it is important to know the most effective ways of water application. One method is to know the best times of the day for watering that will ensure the water is not wasted and plants are not exposed to disease promoting conditions.

Water early in the morning. This is best for plants facing a heat-filled day; it will reduce the chance of stressing plants that feel a lack of water. Watering early can benefit from the dew already laid down. It also helps to discourage fungal growth for plants such as roses; if you water in the evening during humid weather, this encourages the growth of fungal diseases because the foliage lacks a chance to dry out during the night. Lawns also benefit most from early morning watering.
Water during the heat of the day if really needed. If your plants appear to be in dire need of an extra drink during exceptionally hot days, water them sparingly. It is very important to ensure that the water is cool; this means allowing the hose to run cool before using it on plants. Take care watering during windy weather. Avoid using a sprinkler during windy weather, as the water will blow away and evaporate, wasting the water. However, it may be prudent to water plants directly with a container or hose if the plant appears to be drying out too much in the wind.

If you are unable to water early in the morning, late afternoon is the next best; this is after the sun's heat has lost its harshness but before the chill in the air begins to set in.[3]
