“Water-wise” plants will usually thrive in their preferred soil and light conditions with minimal supplemental water after they become established — usually after two years of consistent, deep watering and fertilization. They are also sometimes referred to as “low water use” or “drought-tolerant” (although very few plants can go without any water for a long time).
The first two growing seasons after planting are the most critical to insure that your plant develops a sufficiently deep root system to withstand future drought conditions. With adequate care during this initial period, the plant should withstand minimal watering during typical dry spells.
For more detailed information, please refer to individual cultivar signs, or consult one of Swanson’s nursery professionals. Also pick up our handout, “Water-Wise Gardening Tips.”
