Corona's Principles of Planting How to Guide

Even if a plant is considered “drought tolerant,” it

will require regular irrigation until it is established by

the second or third growing season. Here are some

guidelines to remember:

• Group plants together according to their water

needs. Moisture-loving plants will thrive in a

community with other plants that require the same

level of irrigation. The same is true of plants that

prefer a free-draining, dry site.

• Water slowly, deeply and infrequently rather than

often and sparsely.

• Roots move toward moisture, so be sure to water

both the plant’s original root ball and the soil around

it — helping ensure that roots move out into the

native garden soil. It is important to water deeply to

penetrate down into the root zone as light watering

will only encourage roots to grow toward the surface

of the soil where they’ll be vulnerable to drought

and disease.

• After the ﬁ rst year or once the plants are clearly

well-established and growing strongly, reduce the

frequency of watering.
