Knowing how much water different plants may need becomes crucial during hot summer months. The plants in this Turf Alternatives Garden are low water-use plants and once established will need only 1-2 watering days per week.
The following are rules of thumb when watering. Ultimately, however, a visual assessment of the health and vigor of your plants is your best guide. Water young plants often; they have small root systems and tend to dry out quickly. Older plants have established root systems with plenty of root hairs (the organs that collect the most water for the plant); they do not need as much water as younger plants.
Under hot, dry, and/or windy conditions, plants use water rapidly. Young or shallow-rooted plants may need extra water, as they cannot absorb enough water to keep foliage from wilting.
Water plants at night between sunset and sunrise. Watering in midday when the weather is hot, dry, or windy can waste water due to excessive evaporation. Watering late in the day will keep the soil surface wet all night increasing the chances of soil-borne fungi damaging garden plants.
