How to Water New Landscape on Your Commercial Property

One of the most frequent questions we hear from property managers and building owners is: “How do I properly water my new landscape?” It’s an essential question—especially for commercial properties where first impressions, plant health, and maintenance budgets are all on the line. Proper watering practices not only help your new trees and shrubs thrive but also protect your investment in landscape installation and reduce long-term maintenance needs.

Watering Guidelines for Commercial Properties

Water Immediately After Planting
After installation, each tree and shrub must be deeply watered at the root zone—not just the surface. For larger planting beds, a soaker hose or sprinkler system works best. For individual trees or shrubs, use a slow-trickling hose directly at the base.

Deep Watering Is Critical
Surface moisture evaporates quickly and won’t help with root development. Deep watering allows roots to grow downward and anchor securely—especially important for properties exposed to wind, foot traffic, or variable soil conditions.

• Trees: Water for 1–2 hours based on size
• Shrubs: Water for 20–40 minutes each

Establishing a Schedule
During the first growing season (typically the first year), water newly installed plant material twice a week to ensure strong root establishment. This is especially important for commercial sites with high sun exposure or poor soil retention.

Use of Irrigation Systems
Many commercial properties already have automated irrigation systems. These should be programmed to run twice weekly for 10–20 minutes per zone on planting beds. Continue watering well into the fall—up until the ground freezes. Even dormant plants, especially evergreens, need adequate moisture to withstand winter stress.

How Rain Affects Watering Needs

Don’t assume every rainfall is enough. Only steady, soaking rains that last several hours provide adequate deep soil moisture. Short bursts of heavy rain, especially in clay-heavy or sloped commercial beds, often result in surface runoff without significant root-zone hydration.

Optimal Timing for Watering

Early morning or late evening watering is ideal. These cooler times reduce water loss from evaporation and allow moisture to seep deeper into the soil, promoting healthier root systems.

Avoiding Overwatering

Too much water is just as harmful as too little. Overwatering can lead to root rot, fungal growth, and shallow root systems—which are vulnerable to heat and drought.

Monitor Moisture Like a Pro
Use a simple tool like a wooden dowel or tomato stake. Push it into the soil and pull it out to check for moisture:

• Wet/Muddy? Wait before watering again.
• Dry? Time to water.

Keep in mind that commercial sites often have microclimates—areas near pavement, loading docks, or exposed to wind may dry out faster than shaded or protected zones.
