Understanding Your West Covina Lawn
The foundation of effective lawn care in Southern California is knowing what type of grass you have. Most lawns in West Covina are planted with warm-season grasses, which thrive in the heat and go dormant (turn brown) during cooler winter months 1. The most common varieties include:
- Bermuda Grass: Known for its durability, drought tolerance, and fine texture. It spreads aggressively and recovers well from wear.
- St. Augustine Grass: A coarser, broad-leaf grass that forms a thick, carpet-like lawn and tolerates some shade better than Bermuda.
- Zoysia Grass: Offers a dense, soft turf that is slow-growing but highly resistant to weeds and foot traffic.
Less commonly, you might find cool-season grasses like Fescue or Kentucky Bluegrass, which stay green in winter but struggle in the peak summer heat and require a completely different fertilization and watering schedule 1. Identifying your grass type is the first step, as it dictates the timing and type of nutrients and weed control products that will be most effective.
The Annual Cycle of Lawn Care
A proactive, seasonal schedule is far more effective than reacting to problems as they arise. For warm-season grasses in West Covina, the yearly rhythm of lawn feeding and weed defense looks like this:
Spring (March - May)
As temperatures begin to rise, your lawn exits dormancy. This is a critical window for applying a pre-emergent herbicide to form a barrier in the soil that prevents weed seeds (like crabgrass and spurge) from germinating 1 2. A light, balanced fertilizer application can also be beneficial to kickstart green-up without pushing excessive top growth too early.
Late Spring & Summer (April - June, August)
This is the peak growing season. Your grass is actively using nutrients and water, making it the ideal time for applications of nitrogen-rich fertilizer to promote dense, green growth 1 2. It's also the prime season for post-emergent weed control to spot-treat any broadleaf weeds (like dandelions or clover) that have broken through. Consistent care during this period builds a thick turf that naturally resists weed invasion.
Fall (September - October)
As growth slows, the focus shifts from leaves to roots. A fall application of a balanced or phosphorus-rich fertilizer encourages strong root development, which helps your lawn survive the winter and green up faster next spring 1 2. This is also an important time for weed control, targeting winter annual weeds before they become established.
Winter
Warm-season grasses are typically dormant. Fertilization is not recommended, as it can promote tender growth vulnerable to frost. Weed control may still be necessary for cool-season weeds, but overall, this is a period of minimal intervention.

Core Services: Feeding and Protecting Your Lawn
Professional lawn care programs are built on two interconnected pillars: providing essential nutrients and managing competition from weeds.
Lawn Fertilization
Fertilization is the process of replenishing essential nutrients-primarily Nitrogen (N), Phosphorus (P), and Potassium (K)-that are depleted from the soil over time. A proper lawn feeding program does more than just make grass green; it builds soil health and promotes a dense, resilient turf that can better withstand drought, disease, and foot traffic 1 3. Professionals use formulations specifically calibrated for local soil conditions and grass types, ensuring your lawn gets what it needs without the risk of burn or runoff.
Weed Control
Weeds compete with your grass for sunlight, water, and nutrients. Effective weed management employs a strategic combination of products:
- Pre-emergent Herbicides: Applied before weed seeds germinate, these products create a chemical barrier at the soil surface. They are a proactive cornerstone of any weed prevention plan 1 4.
- Post-emergent Herbicides: These are used to eliminate weeds that are already visible. They can be selective (targeting specific weed types without harming grass) or non-selective (like glyphosate, for use in non-lawn areas) 1 3.
The most successful approach is an integrated lawn care program that combines scheduled fertilization with timed weed control applications. This holistic method addresses both the health of the desired grass and the suppression of unwanted plants, leading to a consistently beautiful lawn 1 4 3.
Understanding Costs for Lawn Services in West Covina
Investing in professional lawn fertilization and weed control provides convenience, expertise, and often, better results than DIY attempts. Costs in West Covina can vary based on your lawn's size, condition, and the comprehensiveness of the program.
Many companies charge on a per-application basis, with typical visits for an average-sized yard ranging from $60 to over $200 depending on the treatments required 5 6 7. These individual visits might include a combination of fertilizer and spot weed control.
For homeowners seeking consistent, year-round results, annual lawn care programs are a popular choice. These bundled plans typically include a set number of seasonal applications (often 4-8 visits per year) and can represent a better value. A basic annual fertilization and weed control plan might start in the range of $300 to $600+ for the year, with prices increasing for larger properties or premium service tiers 5 6 8 9.
Key factors that influence price include:
- Lawn Square Footage: This is the primary cost driver.
- Service Frequency: More visits per year will increase the total cost.
- Lawn Condition & Accessibility: Weedy or unhealthy lawns may require more product or initial remediation. Yards with difficult access can also incur higher charges.
- Additional Services: Many providers offer à la carte add-ons like pest control, aeration, or soil amendments.
Choosing a Local Lawn Care Provider
Finding a reliable professional is crucial. Start by searching for local landscapers and lawn care companies with strong reputations for lawn maintenance and turf care 10 11. Look for providers who offer free, on-site estimates. A reputable professional will walk your property, identify your grass type, discuss your goals, and explain their recommended program-including the specific products they use and their application schedule.
Ask potential providers about their experience with West Covina's common grasses and weeds, their licensing and insurance, and whether their treatments are safe for children and pets. A clear, written service agreement outlining what is included, the schedule, and the total cost will help ensure you and your provider are on the same page for a successful season.
