Watering Guidelines

One of the most important factors in the success of your new landscape is proper watering. Even the highest-quality plants need regular attention and time to establish their root systems. Consistent watering during this period is essential for long-term health and performance.

Deeper Watering > Frequent Shallow Watering

Newly installed plants need moisture that penetrates deep into the root ball and surrounding soil. Even if you water frequently, shallow watering can lead to weak root development and plant stress.

So, how do you know if your plants are getting enough water? 

If you’re using a sprinkler, a good test is to leave a medium sized bowl in the area that is being watered, and measure the depth of the water level after the sprinkler is finished.

The depth should be at least 1/2″ of water. If it isn’t, adjust your timing.

If you are hand watering, count the seconds that you water and then test with your finger. If you stick your finger all the way in and it still feels dry, water while counting again.

Watering Schedule

First 4-5 Weeks After Installation

  • Water twice a day, ideally early morning and late evening so that the sun won’t evaporate your efforts.
  • Water slowly and deeply.
  • Soil should be consistently moist by not soggy.

6-12 Weeks After Installation

  • Continue watering deeply rather than lightly.
  • Increase frequency during periods of heat, drought, or windy conditions.
  • As long as outside temperatures are above 32 degrees Fahrenheit, you can water.

After 3 Months

  • Water once per week.
  • Most plants are becoming established but still benefit from supplemental watering during dry periods.

Watering Guidelines by Plant Type

Trees

  • Apply approximately 10–15 gallons of water per inch of trunk diameter during each watering.
  • Water slowly around the root ball and surrounding soil area.
  • Tree watering bags can be helpful, but do not keep them on the tree for more than 6-8 weeks or they can encourage pests and fungal diseases.

Shrubs & Perennials

  • Apply enough water to thoroughly soak the root ball and surrounding soil.
  • Most newly planted shrubs require approximately 3–5 gallons per watering, depending on size.
  • Perennials require less water per application but may need closer monitoring during hot weather.
  • Check moisture level by inserting your finger 2–3 inches into the soil. If it’s dry, keep going!

Sod & Grass Seed

  • Water for approximately 30-minute sessions, morning and evening.
  • An automatic timer is highly recommended!
  • Monitor the health and progress of the grass. If the blades look slightly gray, or even turn brown, increase the watering time to 45 minutes.
  • Try to keep foot traffic in these areas to a minimum while they get established.

Important Tip!

All plants should be watered at the soil level. The roots transport water throughout the plant. Watering the leaves and flowers encourages diseases and pests. Sunlight can also burn through the water droplets on leaves and petals.

If you are hand watering, be sure to direct the spout below the foliage, to the soil. If you are using a sprinkler, try to time it around sunrise and sunset to avoid the hottest parts of the day.

Weather Considerations

Hot Summer Conditions

Increase watering frequency during periods of:

  • Temperatures above 85°F
  • Drought/Extended dry periods
  • Windy conditions
  • Intense afternoon sun or reflected heat from patios, walls, and driveways

Early Spring/Late Fall

As long as the soil is not frozen, we can plant most things. For our zone, that window is likely between mid-April and late November!

Watering should be completed when the air temperature is above 32 degrees.

Even plants that are going into their dormant stage can benefit from well-watered roots.

Rainfall

Do not assume rainfall has provided adequate water. Light showers often wet only the soil surface. Check moisture by inserting your finger 2–3 inches into the soil. If the soil feels dry, additional watering is needed.

It's All About Balance

Pay attention to the way your plants are responding to your watering care, and adjust as needed. If you’re not sure what’s ailing your plant, you can shoot us a photo for consultation.

Signs Your Plant Needs Water

  • Wilting or drooping leaves
  • Leaves becoming dull or curled
  • Browning along leaf edges
  • Premature leaf drop
  • Dry soil several inches below the surface

Signs of Overwatering

  • Yellowing leaves
  • Constantly saturated soil
  • Mushy stems or leaves
  • Fungal growth or unpleasant odors
  • Wilting despite wet soil

Mulch is Your Friend

A 2–3 inch layer of mulch around new plantings helps:

  • Retain soil moisture
  • Moderate soil temperatures
  • Reduce weed competition
  • Improve overall plant establishment

IMPORTANT: Keep mulch pulled a few inches away from trunks and stems to prevent rot and disease.

A Final Note

The establishment period for new plants can range from several months to more than a year, depending on plant size and species. Consistent watering during the first growing season is the single best investment you can make to ensure your new landscape thrives for years to come.

We also recommend supplemental watering during dry periods for the following two to three years. Once established, healthy plants can typically rely on Mother Nature for their needs, but keep a close eye out for drooping or premature leaf drop.

When in doubt: water deeply, monitor soil moisture regularly, and adjust for weather conditions.

Healthy roots create happy plants.
