What maintenance practice should be done more than once every week?

Watering mature plants deeply is a crucial maintenance practice that typically needs to occur more frequently than just once every week, especially during hot or dry periods. Mature plants, including shrubs and trees, benefit from deep watering because it encourages their root systems to grow deeper into the soil, making them more resilient to drought conditions. Deep watering ensures that moisture reaches the root zone, preventing stress on the plant and promoting healthier growth.

In environments where temperatures are consistently high or where rainfall is scarce, it may be necessary to water mature plants multiple times a week. This practice helps to maintain adequate soil moisture levels, which is vital for the overall health of the plants.

Other practices such as trimming, weeding, and mulching are essential for landscape maintenance but typically do not require as frequent attention as deep watering. For instance, trimming is performed as needed to maintain plant shape and health, while weeding is often done weekly or biweekly, depending on the growth rate of the weeds. Mulching is usually applied once or twice a season, though it may need replenishing less frequently. Hence, the need for deep watering more than once a week stands out in contrast to these other practices.
