When drought restrictions hit Maryland and the greater DMV area, homeowners with irrigation systems often face a frustrating challenge.
You want to keep your lawn and landscape healthy, but local water restrictions limit when and how much you can irrigate.
Over the past 42 years working with homeowners throughout Maryland, DC, and Northern Virginia, I’ve helped many property owners adjust their irrigation strategies during dry seasons and water restriction periods.
The good news is that with the right water management approach, you can still protect your landscape while staying within drought guidelines.
In this article, I’ll walk you through:
- How drought restrictions typically work in Maryland
- The smartest irrigation strategies during water restrictions
- How to prioritize watering when water is limited
- Ways to reduce water usage without harming your lawn
- Common mistakes homeowners make during drought conditions
Because during drought periods, efficient water management matters far more than simply watering more often.
How Drought Restrictions Typically Work in Maryland
During extended dry periods, many counties in Maryland implement outdoor watering restrictions.
These rules are designed to protect local water supplies and reduce unnecessary water usage.
Restrictions often include:
- Limited watering days
- Restrictions on watering times (often early morning or evening only)
- Limits on sprinkler system usage
- Reduced watering for lawns but exceptions for trees and gardens
While these rules vary by county, the goal is always the same: reduce overall water demand during dry conditions.
For homeowners with irrigation systems, this means every watering cycle needs to be more efficient.
Prioritize the Most Important Areas of Your Landscape
One of the most effective drought strategies is prioritizing the areas of your property that truly need irrigation.
During drought conditions, not every part of your yard requires the same level of watering.
Focus on protecting:
- Newly planted trees
- Young shrubs
- Vegetable gardens
- Newly seeded lawns
Established turfgrass is surprisingly resilient and can often tolerate short drought periods by going temporarily dormant.
By concentrating water on the most vulnerable parts of your landscape, you maximize the benefit of limited irrigation.
Water Deeply but Less Frequently
During drought conditions, shallow watering can actually make lawn health worse.
Instead of watering briefly every day, the better approach is deep watering at longer intervals.
Deep watering encourages grass and plant roots to grow deeper into the soil where moisture remains available longer.
Benefits of deep watering include:
- Stronger root systems
- Greater drought tolerance
- Less surface evaporation
In many cases, watering once or twice per week with longer cycles is more effective than daily irrigation.
Water Early in the Morning
One of the simplest ways to conserve water is adjusting irrigation timing.
Early morning watering—typically between 4 a.m. and 8 a.m.—is the most efficient.
At this time of day:
- Temperatures are cooler
- Wind is usually minimal
- Evaporation rates are lower
This means more water actually reaches plant roots instead of evaporating into the air.
Even during drought restrictions, most municipalities still allow watering during early morning hours because it is the most efficient use of water.
Adjust Sprinkler Zones for Maximum Efficiency
If your irrigation system has multiple zones, adjusting those zones can significantly improve water efficiency.
For example:
- Reduce watering time for shaded lawn areas
- Increase efficiency in sunny sections
- Turn off zones that irrigate areas already receiving adequate moisture
Separating irrigation zones by plant type, sunlight exposure, and soil conditions helps ensure water is used effectively.
Use Cycle-and-Soak Irrigation Scheduling
Clay-heavy soils common in Maryland absorb water slowly.
If sprinklers apply water faster than the soil can absorb it, runoff occurs and water is wasted.
Cycle-and-soak irrigation prevents this problem.
Instead of running one long watering cycle, irrigation systems run shorter cycles with rest periods in between.
For example:
- 10 minutes of watering
- 30 minutes of rest
- Another short watering cycle
This allows moisture to soak into the soil gradually.
Reduce Lawn Stress During Drought
Water management during drought isn’t just about irrigation—it also involves lawn care practices.
To protect your lawn during drought restrictions, consider:
- Raising your mower height
- Avoiding excessive foot traffic on stressed grass
- Leaving grass clippings to return nutrients to the soil
Taller grass shades the soil and reduces evaporation, helping retain moisture longer.
Check Your Irrigation System for Waste
During drought restrictions, even small irrigation problems can waste large amounts of water.
Homeowners should inspect their systems for:
- Broken sprinkler heads
- Misaligned spray patterns
- Leaking valves
- Water spraying onto sidewalks or driveways
Fixing these issues ensures every gallon of water is used where it matters.
Consider Smart Irrigation Technology
Modern irrigation systems often include smart controllers that automatically adjust watering schedules based on weather conditions.
These systems use local weather data to determine how much watering is actually needed.
During drought periods, smart controllers can significantly reduce unnecessary watering while maintaining healthy landscapes.
Case Study: Managing Irrigation During a Dry Maryland Summer
One homeowner we worked with had a large lawn and several landscape beds that struggled during a particularly dry summer.
Water restrictions limited irrigation days, which made it difficult to maintain the entire landscape.
Instead of watering everything evenly, we prioritized irrigation zones for young trees and garden beds while reducing lawn watering.
We also adjusted the system to early morning watering and implemented cycle-and-soak scheduling.
The result was a healthier landscape overall—even with reduced water usage.
Common Mistakes During Drought Restrictions
Homeowners often make several mistakes during drought periods.
Watering Too Frequently
Frequent shallow watering weakens plant roots and increases evaporation.
Ignoring System Maintenance
Leaking sprinklers waste water quickly.
Watering at the Wrong Time of Day
Midday watering leads to excessive evaporation.
Treating All Landscape Areas the Same
Different plants have different water needs.
Final Thoughts From Bob Carr
Drought restrictions can make landscape maintenance challenging, but they also encourage smarter water use.
With the right irrigation strategy, homeowners can maintain healthy lawns and landscapes while respecting local water conservation rules.
After more than four decades working with irrigation systems throughout the DMV, one thing remains clear: efficient irrigation design and smart watering practices make all the difference during drought conditions.
