How to Water New Plants

Start new plants off right!

Deeper, infrequent watering helps plants grow healthy extensive roots that stand up better to drought stress. Smart watering makes a big difference in the health of new plants!

Year 1

Spring through Fall (When the Weather is Dry)

• When planting: Water plants as soon as you get them in the ground. Allow the water to soak in, then water again until the soil is thoroughly moistened. (We did this for you)
• Week one: Water plants daily (summer) or every other day (fall-spring). You can skip watering if you get a good amount of rain or snow.
• Week two onward: Unless the weather is extremely hot and dry, decrease watering frequency to two or three times per week until the ground freezes in winter.

Fall - Winter

You will need supplemental water between when irrigation is shut off and when the ground freezes. More rainfall occurs in the fall, but ensure plants get water as described above.

In winter, when the ground is regularly frozen, plants go dormant and need little supplemental water. Watch for long dry periods or early springs. Use buckets to water if there is little snow—one bucket per week is beneficial for trees and large shrubs.

Make sure to turn on your irrigation in a timely fashion.

Years 2 & 3

Water deeply once or twice per week, depending on your soil texture.

After Year 3

Plants should be established and need less watering. Drought-tolerant plants may not need supplemental water, while shallow-rooted or high-water-needing plants may need weekly watering. Many plants may only need watering once or twice a month in dry weather.

Other Tips

• Use water wisely! Water plants when they need it and according to your soil type and the weather.
• Water in the morning to minimize evaporation.
• Check soil moisture before watering—soil should be dry an inch or two below the surface before watering.
• Encourage deep roots by allowing the top inch or two of soil to dry before watering again.
• Mulch retains moisture and reduces evaporation, allowing for less frequent watering.

Special Considerations

• Drought-tolerant plants need regular water until they are established.
• Shallow-rooted plants such as rhododendrons, azaleas, heathers, and bedding plants may need more frequent watering.
• Young trees need deep, regular watering. During dry periods, water deeply once a week until trees are established.
