Maintaining a vibrant, healthy lawn throughout the year requires dedication and a strategic approach. Just like a well-tuned engine needs regular maintenance, your lawn thrives on a consistent care schedule. Timing is crucial when it comes to lawn care; applying fertilizers and weed controls, especially pre-emergent herbicides, at the right moment is key to maximizing their effectiveness. A well-planned Annual Lawn Care Program will help you stay organized and ensure your lawn receives the attention it needs in every season.
Understanding your grass type and local climate conditions is the foundation of any successful lawn care program. Grasses are broadly classified into cool-season and warm-season varieties. Cool-season grasses flourish in cooler temperatures and experience their primary growth periods during spring and fall, while warm-season grasses thrive in the heat of summer. Knowing which type you have is the first step in tailoring your annual lawn care program. If you are unsure about your grass type, your local county extension office is an invaluable resource for identifying your turfgrass and providing region-specific advice.
This guide will provide a detailed breakdown of a year-round lawn care program, offering seasonal tips and step-by-step instructions to help you achieve a beautiful, golf course-quality lawn. Let’s dive into creating your annual lawn care program.
1. Spring Lawn Care: Revitalizing Your Lawn After Winter
Spring is a critical period in your annual lawn care program, focused on waking up your lawn after winter dormancy and setting the stage for healthy growth throughout the year. As the ground thaws and the first signs of green appear, it’s time to implement these essential spring lawn care tasks.
February, March, April, May: Key Spring Months
After the dormancy of winter, spring marks a significant transition for your lawn. As temperatures rise, your grass begins to actively grow again, signaling the start of the busiest season in your annual lawn care program. Spring lawn care is crucial for repairing winter damage and preventing future problems stemming from weakened turf. A proactive approach in spring will lead to stronger, more resilient grass throughout the year.
Pre-Emergent Herbicide Application: February
The first step in your spring lawn care routine, typically around mid-February, is applying a pre-emergent herbicide. Pre-emergents are a vital component of weed control, preventing weed seeds from germinating and establishing themselves in your lawn. This early application is a preemptive strike against common spring and summer weeds, saving you significant effort later in the year.
For an effective pre-emergent, consider Prodiamine .38% with Fertilizer 0-0-7. This granular product combines pre-emergent weed control with a boost of potassium (7%), an essential nutrient for healthy grass development. The granular form is easy to apply and safe for your lawn when used as directed. For application guidance, numerous online video tutorials are available, providing visual demonstrations for optimal application techniques.

Spring Clean-Up and Dethatching: March
Winter often leaves behind a layer of debris on your lawn, including fallen leaves and dead grass. March is the time for a thorough spring clean-up. Begin by raking or blowing away any accumulated organic matter. This clears the way for essential lawn care practices like dethatching.
Dethatching is the process of removing excess thatch, a layer of both living and dead organic matter that builds up between the soil surface and the grass blades. A thin layer of thatch (less than half an inch) is beneficial, helping to retain moisture and protect the soil. However, excessive thatch can impede air, water, and nutrients from reaching the roots, and can harbor pests and diseases.
Use a dethatching rake to manually remove thatch or consider a verticutting machine for larger lawns. Verticutting involves making shallow vertical cuts into the soil, which helps to break up thatch and stimulate new grass growth. Another option for dethatching is lawn scalping, which can be done with a lawn mower set to a low setting.

Soil Testing: March – Understanding Your Lawn’s Needs
Healthy soil is the foundation of a thriving lawn. Spring is the ideal time to conduct a soil test. A soil test analyzes your soil’s nutrient levels and pH, providing crucial information for effective fertilization and soil amendments. Knowing your soil’s specific needs prevents over-fertilization, saves money, and minimizes environmental impact from fertilizer runoff.
Invest in a reliable soil test kit. Kits like the MySoil Starter Soil Test Kit offer comprehensive analysis, identifying nutrient deficiencies and pH imbalances. Test results often include tailored fertilizer recommendations to address your lawn’s specific needs.
Depending on your soil test results, you might need to adjust your soil pH. If your soil is too acidic, use products to raise the pH. If it’s too alkaline, use products to lower it. For micronutrient deficiencies, consider applying a liquid micronutrient fertilizer to provide essential trace elements.

Core Aeration: March – Improving Soil Health
Aeration is another crucial spring lawn care task, particularly beneficial for compacted soils. Soil compaction reduces air, water, and nutrient flow to the roots, hindering healthy grass growth. Aeration alleviates compaction, improving soil structure and promoting deeper root growth.
Core aeration involves removing small plugs of soil from your lawn using an aerating tool. These soil plugs decompose on the surface, returning valuable nutrients to the soil. Alternatively, spiked aeration tools are available, but core aeration generally provides more lasting benefits. Aeration improves fertilizer uptake and overall lawn health. For best results, aerate in late March or early April, depending on when your grass emerges from dormancy.
Topdressing: April – Smoothing and Enriching Your Lawn
Topdressing is the application of a thin layer of material, typically compost or a sand/soil mix, over your lawn after aeration. Topdressing smooths out uneven surfaces, filling in aeration holes and creating a more level lawn. It also enriches the soil with organic matter, improving soil structure and fertility.
Topdressing is particularly beneficial for lawns with heavy clay soils, as it improves soil porosity over time. While topdressing can be done manually, for larger lawns, professional services may be more efficient for core aeration and topdressing.
Insecticide and Fungicide Application: April – Preventative Care
As temperatures warm up in April, insect pests and fungal diseases become more active. Spring is the time to apply preventative insecticide and fungicide treatments to protect your vulnerable lawn. Grass emerging from winter dormancy is often stressed and more susceptible to pests and diseases.
Consider using a broad-spectrum insecticide like Acelepryn G, which targets common lawn pests while being safe for beneficial pollinators and earthworms. A single spring application can provide season-long pest control. For fungal disease prevention, Headway G granular fungicide or Pillar SC liquid fungicide are effective options, controlling a wide range of common lawn diseases.

Fertilization: April – Nourishing Spring Growth
Mid-April, when soil temperatures consistently reach 55°F, is generally the optimal time for spring fertilization. Use a soil thermometer for accurate soil temperature readings. Visible signs of grass growth and blooming flowers also indicate it’s time to fertilize. Spring fertilization provides the nutrients your lawn needs for vigorous growth after winter dormancy.
Consider using Lebanon Turf’s Humic Max fertilizer in early spring to improve soil quality and provide an early nutrient boost. This sets the stage for healthy, robust growth throughout the growing season.

Mowing: March/April – Starting the Season Right
The timing for your first mow of the season depends on your location and grass type. Wait until temperatures are consistently above 50°F and the grass is at least 2-2.5 inches tall before mowing. Mowing too early or too short can stress the grass and hinder root development.
When you begin mowing, follow the one-third rule: never remove more than one-third of the grass blade length in a single mowing. Maintain a regular mowing schedule, typically twice a week, to encourage healthy growth and a dense, attractive lawn.

Plant Growth Regulator (PGR) Application: May – Managing Growth
In early May, consider applying a plant growth regulator (PGR). PGRs are compounds that regulate plant growth, slowing vertical growth and promoting lateral growth and denser turf. PGRs reduce mowing frequency and enhance lawn color by encouraging darker, mature leaf blades.
Primo Maxx is a popular PGR option, applied every 4-6 weeks starting in early May. Use a backpack sprayer for even application. PGRs are a valuable tool in achieving a golf course-quality lawn with less frequent mowing.
2. Summer Lawn Care: Maintaining Health Through Heat
Summer lawn care focuses on maintaining the health and appearance of your lawn through the stresses of heat and potential drought. While spring is about establishment, summer is about consistent maintenance and protection.
June, July, August: Summer Maintenance Months
Summer lawn care is highly dependent on your geographic location and climate. Hot and dry conditions can be particularly challenging for lawns. Maintaining adequate moisture, controlling weeds and pests, and adjusting mowing practices are crucial for summer lawn health. Another PGR application in early June can help manage growth during the peak summer months.
Summer Mowing Practices: June – August
During the summer, grass growth typically accelerates. Adjust your mower height to a higher setting. Taller grass blades provide more shade for the soil, reducing evaporation and weed germination. Continue to adhere to the one-third rule when mowing, but raise your mowing height to promote deeper root systems and healthier turf during the heat.
Watering Strategies: June – August
Proper watering is paramount during the summer. Aim to water deeply and less frequently, about 1-1.5 inches of water per week, typically 2-3 times per week. Water deeply enough to encourage deep root growth, which makes your lawn more drought-tolerant. Early morning watering (4-6 AM) is ideal, minimizing water loss through evaporation and wind.
To conserve water, consider using Hydretain, a water retention product that helps draw moisture from the soil to the roots, reducing watering needs by up to 50%.
Summer Weed, Disease, and Pest Control: June – August
Even with spring preventative measures, weeds, diseases, and pests can still emerge during the summer. Regular monitoring is essential. Be vigilant for signs of weed infestations or pest activity.
For targeted weed control without harming your grass, consider these selective herbicide options:
-
Celsius WG Broadleaf and Grassy Weed Control (Warm-Season Grasses): Effective against over 150 weed species, including summer annuals like dandelions. Safe for warm-season grasses even in high temperatures.
-
Certainty Herbicide (Warm-Season Grasses): Targets Poa Annua, dandelions, and nutsedge. Effective across a wide temperature range, suitable for spring, summer, and fall use.
-
Tenacity Herbicide (Cool-Season Grasses): A versatile herbicide for cool-season lawns, effective as both pre- and post-emergent control against over 46 weed species.
-
Sedgehammer® Herbicide (Cool and Warm-Season Grasses): Specifically targets nutsedge, kyllinga, and other broadleaf weeds, safe for both cool and warm-season turfgrass.
To enhance the effectiveness of herbicides, insecticides, and fungicides, use surfactants like Hi-Yield Spreader Sticker. Surfactants improve product adhesion, absorption, and translocation, leading to faster and more effective results. Consider purchasing pre-packaged herbicide kits for cool-season and warm-season lawns for convenient summer weed control.
Monitor for grub infestations during the summer months. Grubs feed on grass roots and can cause significant damage.

3. Fall Lawn Care: Preparing for Winter and Spring Green-Up
Fall lawn care is crucial for both cool-season and warm-season grasses, although the focus differs slightly. For cool-season grasses, fall fertilization promotes strong root development for winter hardiness and spring green-up. Warm-season grasses prepare for dormancy.
September, October: Fall Preparation Months
Fall is a time to repeat some spring lawn care practices to prepare your lawn for the dormant winter months and ensure a healthy start in the spring.
Fall Fertilization and Fungicide Application: September
Cool-season grasses benefit significantly from fall fertilization, building carbohydrate reserves for winter survival and spring growth. Warm-season grasses can also benefit from a late-season fertilizer application to improve winter hardiness. Conduct another soil test to determine your lawn’s nutrient needs before fall fertilization.
Consider using Lebanon Turf’s Humic Max fertilizer or Golf Course Lawn Store’s Stress 12-0-24 or Mirimichi Green’s Release 901C™ fertilizers. These options provide essential nutrients for fall lawn health. September is also the time for a preventative fall fungicide application, as damp conditions and leaf debris can promote lawn diseases. Headway G or Caravan® G fungicides are effective choices for fall disease control.
Fall Pre-Emergent Herbicide Application: September
Apply a pre-emergent herbicide in the fall to prevent winter and early spring weeds. As your lawn enters dormancy, weeds can take advantage of the reduced competition. Dithiopyr .15% or Prodiamine 65 WDG are effective fall pre-emergent herbicides.
Fall Aeration and Overseeding: September
For cool-season lawns, fall is an excellent time for aeration and overseeding, especially if your lawn experienced thinning or bare patches during the summer. Aerate your lawn in early fall, followed by overseeding with a grass seed variety suitable for your region. Remove thatch and debris before overseeding, loosen the soil, and incorporate compost or fertilizer to improve seed establishment.
Fall Clean-Up: September – October
Continue to keep your lawn clean throughout the fall. While a light layer of leaves can be beneficial, excessive leaf accumulation can smother your lawn, hindering growth and promoting winter lawn diseases like snow mold. Rake, blow, or mulch fallen leaves. Mulching leaves with a mower returns valuable nutrients to the soil.

4. Winter Lawn Care: Dormancy and Equipment Maintenance
Winter lawn care is minimal as most grasses enter dormancy. Focus on protecting your dormant lawn and maintaining your lawn care equipment.
November, December, January: Winter Dormancy Months
During winter, most grass types become dormant, and lawn care activities are significantly reduced. Avoid heavy traffic on your lawn during winter to prevent soil compaction and damage to dormant grass. Winter is an excellent time to service your lawn care equipment. Clean and store spreaders and sprayers, sharpen mower blades, and inspect irrigation systems. This proactive maintenance ensures your equipment is ready for the spring season.
