5 Lawn Care Mistakes to Avoid This Summer

Summer brings warmer temperatures, increased sunlight, and higher foot traffic — all of which can take a toll on your lawn. Maintaining a lush, healthy lawn through the summer requires more than just regular mowing and watering. Many homeowners and businesses unknowingly make lawn care mistakes that lead to thinning grass, brown patches, and increased weed growth.

At 519 Property Maintenance, we provide expert lawn care services in Woodstock, Brantford, Ingersoll, Tavistock, Princeton, Paris, Burford, Cambridge, London, and Norwich. In this guide, we’ll cover the most common summer lawn care mistakes and how to avoid them to keep your lawn looking its best all season long.

Mistake #1: Mowing Too Short

One of the most common mistakes homeowners make when it comes to lawn care is mowing their grass too short, often referred to as "scalping." Many believe that cutting their grass down to a shorter height will result in less frequent mowings, but this misconception can lead to a range of problems that ultimately harm the lawn. Grass, like all plants, requires a certain height to thrive. When mowed too short, the grass is deprived of the necessary surface area for photosynthesis, which can weaken the plant and make it more susceptible to stress and disease. This can also lead to an uneven lawn, as the shorter grass struggles to grow or recover as quickly as its taller counterparts.

In addition to the immediate repercussions on grass health, mowing too short can also contribute to long-term issues like weed infestation and soil erosion. With less grass coverage, broadleaf weeds can take advantage of the bare patches and establish themselves more easily. Furthermore, shorter grass offers less protection to the soil, making it more vulnerable to the elements. Homeowners should aim to keep their grass at an optimal height — typically around 2.5 to 4 inches, depending on the type of grass — to ensure healthier growth, reduce the need for herbicides, and create a lush, green lawn that can withstand changing weather conditions. By avoiding the urge to mow too short, homeowners can foster a resilient lawn that enhances their outdoor space for years to come.

The Problem:

Cutting your grass too short might seem like a time-saver, but it weakens the grass and creates an opportunity for weeds to take over.

Why It’s a Problem:

• Short grass blades have a harder time absorbing sunlight, reducing root growth.

• Weeds thrive in thin, stressed lawns.

• Increased exposure to heat leads to brown patches and soil dryness.

How to Fix It:

✔️ Keep grass height at about 3 inches.

✔️ Use a sharp mower blade to avoid tearing the grass.

✔️ Adjust the mower height based on the grass type and season.

👉 Pro Tip: Mow in alternating directions each time to prevent ruts and promote even growth.

Example: In Woodstock and Brantford, the ideal mowing height for cool-season grasses (like Kentucky bluegrass) is about 2.5 to 3 inches. Taller grass provides better shade to the soil and reduces moisture loss.

Mistake #2: Over-Watering

Over-watering is a common pitfall that many plant enthusiasts encounter, regardless of their gardening experience. This mistake occurs when plants receive more water than their root systems can absorb, leading to a range of detrimental consequences. Excess water saturation can inhibit oxygen flow to the roots, creating a breeding ground for harmful fungi and bacteria. As a result, plants may suffer from root rot, which can ultimately lead to their decline or even death if not addressed promptly. Gardeners may overlook the signs of over-watering; however, yellowing leaves, wilting, and an unpleasant odour from the soil are all telltale indicators that they are providing their plants with too much leaching moisture.

To avoid the pitfalls of over-watering, it is crucial for gardeners to develop a keen understanding of their plants’ specific needs. Factors such as the type of soil, the plant’s size, and environmental conditions like temperature and humidity play significant roles in determining how much water is required. Implementing a soil moisture testing routine can greatly assist in gauging when a plant truly needs watering. By allowing the topsoil to dry out between watering sessions, gardeners can create a healthier environment for their plants. Ultimately, striking the right balance in watering not only ensures the vitality of the plants but also enhances the overall gardening experience.

The Problem:

Watering too frequently or applying too much water at once can lead to shallow roots, increased disease risk, and poor soil health.

Why It’s a Problem:

• Excess water prevents oxygen from reaching grass roots.

• Promotes fungal growth and lawn diseases.

• Causes runoff, washing away nutrients from the soil.

How to Fix It:

✔️ Water deeply but infrequently (about 1 inch per week, including rainfall).

✔️ Water in the early morning to reduce evaporation.

✔️ Use a rain gauge to monitor water levels.

👉 Pro Tip: In areas like Cambridge and London, where summer heat is intense, monitor rainfall and adjust watering schedules as needed.

Mistake #3: Ignoring Soil Health

One of the most significant yet often overlooked factors in successful gardening and farming is soil health. Ignoring the condition of the soil can lead to a cascade of negative effects, impacting not only plant growth but also the overall ecosystem. Healthy soil is a living entity, teeming with microorganisms, nutrients, and organic matter that work together to sustain plant life. When gardeners and farmers fail to prioritise soil health, they may experience stunted plant growth, increased susceptibility to pests and diseases, and ultimately, diminished crop yields. This oversight can be particularly damaging in the long run, as poor soil health becomes increasingly difficult and costly to rectify.

To ensure the vitality of their gardens or fields, it is crucial for cultivators to regularly assess and amend their soil. This may involve incorporating organic matter, such as compost or well-rotted manure, to boost nutrient levels and improve soil structure. Additionally, practices such as crop rotation and cover cropping can enhance biodiversity and promote soil health. Ignoring these practices may lead to a reliance on chemical fertilizers, which can further deplete soil vitality over time. By recognising the importance of soil health and actively cultivating it, gardeners and farmers can create a more sustainable and productive growing environment, ultimately benefitting both their crops and the surrounding ecosystem.

The Problem:

Even with proper mowing and watering, poor soil quality can limit grass growth and increase the risk of disease.

Why It’s a Problem:

• Compacted soil prevents water and nutrients from penetrating the roots.

• Low nutrient levels lead to weak, thin grass.

• Improper pH levels affect nutrient absorption.

How to Fix It:

✔️ Aerate the lawn in early summer to loosen compacted soil.

✔️ Apply a balanced fertilizer to improve nutrient levels.

✔️ Test soil pH and adjust with lime or sulfur if needed.

👉 Pro Tip: In areas with heavy clay soil, such as Ingersoll and Norwich, aeration is especially important to promote drainage and root health.

Mistake #4: Failing to Control Weeds Early

In the realm of gardening and landscaping, one of the most detrimental missteps is the failure to manage weeds early in the growing season. Weeds are not only unsightly but also compete vigorously with desirable plants for essential resources such as water, nutrients, and sunlight. When left unchecked, they can proliferate rapidly, leading to more extensive infestations that are much harder to eradicate later on. The key to effective weed management lies in early intervention; this involves both prevention strategies and the timely removal of broadleaf weeds before they can establish themselves.

Implementing a proactive approach to weed control can significantly improve the health and productivity of a garden. Gardeners are encouraged to regularly inspect their plots for weeds and to utilise tools like mulching and regular hoeing to suppress weed growth. Moreover, integrating techniques such as crop rotation and maintaining healthy soil can promote robust plant growth while discouraging weed establishment. By taking decisive action at the first sign of weeds, gardeners not only safeguard their plants but also reduce the time and effort required for later remediation. In essence, addressing weeds promptly is a fundamental component of successful gardening that can yield thriving landscapes and bountiful harvests.

The Problem:

Letting weeds take root in early summer can lead to a lawn overrun with invasive plants.

Why It’s a Problem:

• Weeds compete with grass for nutrients and water.

• Some weeds, like crabgrass, spread rapidly and are difficult to control once established.

• Weeds create an uneven lawn appearance and weaken overall grass health.

How to Fix It:

✔️ Apply a pre-emergent herbicide in late spring or early summer to prevent weed growth.

✔️ Spot-treat weeds with a post-emergent herbicide.

✔️ Maintain proper mowing and watering practices to strengthen the grass and naturally prevent weed growth.

👉 Pro Tip: Weeds are especially aggressive in high-traffic areas like commercial properties in Brantford and Cambridge. Stay ahead of the problem with early-season treatments.

Mistake #5: Skipping Fertilization

One of the most common oversights in gardening and landscaping is the failure to incorporate a proper fertilization schedule into plant care routines. Many amateur gardeners underestimate the importance of nutrients in promoting healthy growth, leading to stunted plants and a less vibrant garden. Fertilization plays a crucial role in replenishing the soil with essential nutrients that may have been depleted over time, especially in areas with heavy planting. By neglecting to fertilize, gardeners risk depriving their plants of the necessary components for photosynthesis, growth, and overall vitality, including phosphorus.

Furthermore, skipping fertilization can result in an imbalanced ecosystem within the garden. Soil nutrients are vital for beneficial microorganisms that break down organic matter and support plant health. Without proper fertilization, not only do plants suffer, but the entire garden community can be adversely impacted. Gardeners are encouraged to incorporate a balanced fertilization regime, tailored to their specific plants and soil conditions. This ensures that each plant receives the required macronutrients and micronutrients, allowing for robust growth and an aesthetically pleasing landscape. Regular fertilization can mean the difference between a mediocre garden and a flourishing haven of phosphorus and life.

The Problem: `.

Skipping summer fertilization can leave your lawn vulnerable to heat stress, poor color, and slow recovery from damage.

Why It’s a Problem:

• Grass requires nutrients to stay green and healthy in hot weather.

• Poor nutrient levels make grass more susceptible to disease and pests.

• Summer stress leads to slower growth and patchy coverage.

How to Fix It:

✔️ Apply a slow-release fertilizer in early to mid-summer.

✔️ Choose a fertilizer formulated for summer heat tolerance.

✔️ Water the lawn after fertilizing to help nutrients absorb into the soil.

👉 Pro Tip: In hot regions like London and Cambridge, use a low-nitrogen fertilizer to avoid overstimulation, which can stress the grass during extreme heat.

Seasonal Lawn Care by Location

Seasonal lawn care varies greatly depending on geographical location, as different regions experience unique climate patterns and weather conditions throughout the year. For instance, homeowners in the southern provinces of Canada, such as British Columbia and parts of Ontario, tend to have a longer growing season. In these areas, spring lawn care begins earlier, often in March or April, with activities such as fertilization, lawn aeration, and overseeding to promote healthy grass growth. Regular watering and pest management are also essential during the warm months to mitigate heat stress and prevent infestations.

Conversely, homeowners in the northern provinces, such as Manitoba and Saskatchewan, face a shorter growing season, typically beginning in late May or early June. In these regions, seasonal lawn care focuses on maximizing growth during the limited warm months. This often includes a robust fertilization schedule, proper mowing heights, and frequent watering during dry spells. As temperatures drop in late summer and early autumn, prioritizing tasks like leaf removal and preparing the lawn for winter becomes critical. Understanding the specific needs of a lawn based on its regional climate enables homeowners to take the right steps towards achieving a lush, green yard year-round.

At 519 Property Maintenance, we understand that every lawn is different, and the local climate plays a significant role in lawn health.

Common Questions About Summer Lawn Care

How often should I water my lawn in the summer?

• Water deeply 1–2 times per week, providing about 1 inch of water.

• Adjust based on rainfall and soil type.

When it comes to maintaining a vibrant lawn during the summer months, understanding the right watering schedule is essential. During the hot summer days, grass tends to experience increased evaporation and may become stressed due to high temperatures. Generally, homeowners should aim to water their lawns about once or twice a week, providing approximately 2.5 to 5 centimetres (1 to 2 inches) of water each time. This regime allows the soil to absorb moisture deeply, encouraging deep root growth, which is crucial for the overall health of the grass. It’s important to water early in the morning, ideally between 5 a.m. and 10 a.m., as this timing minimises evaporation and ensures that the grass has ample time to dry before evening, reducing the risk of fungal diseases.

In addition to maintaining a consistent watering schedule, it is vital to be mindful of other factors that can influence how often the lawn needs to be watered. Variations in soil type, grass species, and local climate can significantly affect the lawn's moisture needs. For instance, sandy soils drain quickly and may require more frequent watering compared to clay soils, which retain moisture for longer periods. Homeowners should monitor their lawns for signs of dehydration, such as a dull green colour or footprints that remain visible on the grass. Adjusting the watering routine based on these observations, as well as factoring in any rainfall, will contribute to a lush, green lawn throughout the summer while conserving water resources.

Is it okay to mow during a heatwave?

• Mow less frequently during extreme heat to reduce stress on the grass.

• Keep mower blades sharp to minimize damage.

Mowing during a heatwave can be a contentious topic among lawn care enthusiasts. While some may argue that maintaining a neat lawn is essential, professionals recommend considering the health of both the grass and the individual performing the task. Lawn grass is particularly vulnerable during times of extreme heat, as it enters a state of dormancy to conserve moisture. Mowing during such conditions can cause additional stress to the grass, potentially leading to brown patches and long-term damage. Furthermore, the heat poses significant risks to the individual mowing the lawn, increasing the likelihood of heat-related illnesses due to prolonged exposure to high temperatures.

If mowing is absolutely necessary, it’s advisable to do so early in the morning or later in the evening when temperatures are cooler and humidity levels are potentially more manageable. This approach not only minimizes stress on the lawn but also reduces the risk of heat exhaustion for the person operating the mower. Additionally, keeping the mower blades sharp can help promote an even cut, as jagged edges can further stress the grass. Ultimately, while it is technically possible to mow during a heatwave, prioritizing the health of the lawn and personal safety should take precedence in any decision related to lawn maintenance during extreme weather.

How do I stop crabgrass from spreading?

• Apply a pre-emergent herbicide in early spring.

• Maintain healthy grass coverage to prevent crabgrass from taking root.

Crabgrass can be a relentless invader in lawns, diminishing the overall appearance and health of one’s green space. To prevent crabgrass from spreading, it is crucial to adopt a multi-faceted approach that emphasizes pre-emergent control and healthy lawn practices. A proactive measure includes applying a pre-emergent herbicide in early spring, before the temperatures reach 16°C. This method effectively prevents the crabgrass seeds from germinating, allowing desirable grass species to establish themselves without competition. Homeowners should also be diligent in maintaining their lawns through regular mowing, as keeping grass at a height of about 7.5 to 10 cm can help shade the soil, making it difficult for crabgrass seeds to thrive.

In addition to chemical control, fostering a vigorous, thick lawn through proper watering, fertilizing, and aeration can significantly reduce the chances of crabgrass establishing itself. Lawns that are well-nourished and receive adequate attention are better equipped to outcompete crabgrass and other weeds. It's also important to mitigate soil compaction and improve drainage since crabgrass tends to thrive in weak, stressed environments. Ultimately, the key to stopping crabgrass lies in creating an environment that favours desirable grass while minimising the conditions that allow crabgrass to flourish.
