Summer Landscaping Mistakes to Avoid: What Homeowners Get Wrong

Summer is when your yard gets the most attention—from backyard BBQs to late evening hangouts—but it’s also when landscaping issues are most likely to show up. At Skyline Exteriors Landscaping, we often see homeowners making well-intentioned mistakes that can cause long-term damage to their outdoor spaces. Here are some of the most common pitfalls to avoid, and what you can do instead to keep your landscape thriving all summer long.

Overwatering or Underwatering

One of the most common mistakes is improper watering. In the heat of summer, it’s tempting to water plants every day, but overwatering can be just as damaging as underwatering. Too much water suffocates roots and creates conditions for fungus and rot, while too little water stresses plants and leads to wilting or browning. The key is to water deeply and less frequently—ideally early in the morning to reduce evaporation and allow moisture to soak in. Most lawns only need about an inch of water per week. Using drip irrigation or soaker hoses can also help deliver water efficiently without runoff.

Ignoring Soil Health

Many homeowners focus on what’s visible—plants, flowers, and turf—while ignoring the condition of the soil beneath. Poor soil leads to weak plant growth, drainage issues, and nutrient deficiencies. Summer’s heat can exacerbate these problems. It’s essential to test your soil for pH and nutrient content and amend it with compost or organic matter to support healthy plant life. Good soil promotes stronger root systems and resilience during summer stress, making it the true foundation of a healthy landscape.

Planting at the Wrong Time

It’s common to want to install new plants or lay sod during summer since it's when many people have time to tackle outdoor projects. However, summer is one of the worst times to introduce new plantings, as the extreme heat and dry conditions make it difficult for roots to establish. If you must plant during this season, choose native or heat-tolerant species and be prepared to water and shade them as needed. Ideally, save major planting for spring or fall, when temperatures are milder and plants can acclimate more easily.

Misusing or Skipping Mulch

Mulch is one of the simplest tools for maintaining a healthy landscape, yet it's often misused. Applying too much mulch or piling it up against tree trunks (a practice known as volcano mulching) can trap moisture against bark and attract pests. On the other hand, skipping mulch altogether allows soil to dry out and weeds to take over. The ideal approach is to apply 2–3 inches of mulch around plants and beds, keeping it a few inches away from stems and trunks. This helps regulate soil temperature, retain moisture, and suppress weeds.

Cutting Grass Too Short

Scalping the lawn—cutting it too short—is another summer mistake that can stress turf and invite weeds. Many homeowners do this thinking it will reduce mowing frequency, but short grass exposes the soil to sunlight, dries it out, and weakens the lawn overall. Instead, keep your mower blade set high—around 3 inches for most grass types. Taller grass shades the soil, conserves moisture, and promotes deeper, stronger roots.

Skipping Regular Maintenance

Summer maintenance often gets sidelined due to busy schedules or vacations, but ignoring small tasks can lead to bigger problems. Weeds, overgrown shrubs, and dead flowers can quickly make a yard look messy and neglected. Routine upkeep like weeding, deadheading, edging, and light pruning keeps your landscape neat and healthy. Dedicating just 15–20 minutes a few times a week can make a noticeable difference and prevent more costly fixes down the line.

Neglecting Hardscape Elements

While most landscaping advice focuses on plants, your hardscape—patios, walkways, retaining walls—needs seasonal attention too. In summer, sun and weather can cause fading, cracking, or shifting in materials like pavers and concrete. Weeds may sprout between cracks, and moss or mildew can make surfaces slippery. Cleaning, resealing, and re-leveling hardscapes helps maintain both safety and appearance. Don’t forget to check your outdoor lighting and repair any fixtures that aren’t working properly to keep your space functional after sunset.

Plan Smart to Enjoy Summer More

Avoiding these summer landscaping mistakes doesn’t require a complete overhaul—just a little planning, observation, and consistency. By giving attention to watering, soil, lawn care, and maintenance, you’ll enjoy a healthier, more attractive yard all season long.
