Why Watering Practices Matter for Weed Prevention
When it comes to keeping your lawn lush, green, and free of uninvited weeds, the way you water is just as important as how you mow or fertilize. Too little water can weaken your grass, opening the door for opportunistic weeds. However, overwatering or watering too frequently can promote weed growth by creating consistently moist conditions that encourage weed seeds to germinate.
In Bakersfield, California, and the surrounding communities, we have warm, dry summers and mild winters. This climate requires a clear, strategic approach to lawn care—particularly when it comes to irrigation. By understanding the different watering requirements for Bermuda grass versus cool-season grasses (like rye and fescue), you can significantly reduce weed pressure and cultivate a lawn that’s both hardy and healthy.
Understanding Bermuda Grass Watering Needs
1. Growing Season (Warm Months)
Frequency: 2-3 times per week
Depth: Deep watering (about 6-8 inches into the soil)
Bermuda grass thrives in warm weather and goes into dormancy when temperatures dip. During its active growing season—usually late spring through early fall—you want to water deeply but infrequently. This encourages roots to grow downward in search of water, creating a stronger, more drought-resistant lawn. Bermuda grass can handle heat very well, which is why it doesn’t need daily watering. Instead, it relies on deep watering sessions that keep the root zone consistently moist but not oversaturated.
2. Dormant Season (Cool Months)
Frequency: Typically no watering required
Reasoning: Dormant Bermuda is brown, but not dead
In winter or cooler months, Bermuda grass typically turns brown and enters a dormancy phase. While it may look unappealing, the grass is simply resting until warmer temperatures return. Unless we experience an uncharacteristically dry winter or warm spells, you generally don’t need to water dormant Bermuda grass. Overwatering a dormant lawn can lead to soggy conditions, potentially encouraging moss or weeds that thrive in damp soil.
Cool-Season Grasses (Rye and Fescue)
1. Cool Season (Fall and Spring)
Frequency: 1-2 times per week
Depth: Deep watering to encourage strong roots
Rye and fescue grasses love moderate temperatures. During the cooler part of the year, they maintain active growth, so they benefit from regular yet moderate watering. One or two deep watering sessions per week usually suffice, ensuring the soil is moist down to the root level. Proper watering during these cooler months allows these grasses to develop robust root systems, making them more resistant to both drought and weeds.
2. Hot Weather Conditions
Frequency: Potentially every day or more
Reasoning: Prevent heat stress and browning
Once the summer heat sets in, rye and fescue often struggle because they aren’t naturally adapted to extremely high temperatures. During very hot spells, these lawns may need daily watering—or even more—to avoid going dormant or experiencing die-off. Monitor your lawn closely: if you notice wilting, footprints that don’t bounce back quickly, or a dull bluish-gray hue, it’s time to water.
However, be cautious not to overwater. If your lawn stays continuously wet for long periods, you risk fungal diseases and rampant weed germination. Strike a balance by adjusting your watering schedule based on rainfall, soil conditions, and daily temperatures.
How Overwatering Encourages Weed Growth
Weeds thrive in conditions where grass is weak or the soil is perpetually moist. Overwatering can create an environment that invites:
Shallow Roots for Grass: If water is always near the surface, grass roots have little incentive to grow deeper. Shallow roots make turf more susceptible to stress, pests, and—you guessed it—weed invasions.
Ideal Conditions for Weed Seeds: Many weed species germinate in moist soil. Overwatering keeps the top layer of soil damp, which is precisely the environment these seeds need.
Increased Fungal Diseases: Constantly wet lawns are more prone to diseases like dollar spot or brown patch, which weaken turf and allow weeds to take over.
By taking a strategic, moderate approach to watering, you reduce these risks, giving your grass the edge over weeds.

Tips for Establishing a Healthy Watering Routine
Measure Soil Moisture
Use a soil probe or a simple screwdriver test to ensure you’re watering deeply enough. If it’s challenging to penetrate the soil, you likely need a deeper soak.Water Early
Irrigate your lawn in the early morning (before 9 AM) to reduce evaporation. Watering in the late evening might increase the risk of fungal diseases as moisture sits on the blades overnight.Watch for Runoff
If water begins to run off onto sidewalks or streets within a few minutes, you’re likely watering too fast or too much. Consider a cycle-and-soak method, where you split watering times into two or three shorter sessions.Know Your Grass
Bermudagrass, ryegrass, and fescue each have unique needs. Adjust your watering schedule accordingly, especially during seasonal transitions.Adjust for Rain
If nature provides sufficient rainfall, scale back on scheduled watering. Overwatering after a storm can do more harm than good.
