A lush, well-planned landscape can transform any home’s exterior into a personal retreat. But even the most enthusiastic DIY gardeners can make costly landscaping mistakes that affect a yard’s health and beauty. At Greenstone Gardens, we’ve seen it all — and after more than 44 years in the industry, we know that small missteps can lead to big problems down the line.
If you’re designing or maintaining your outdoor space, here are some of the most common pitfalls to avoid — and how to fix them before they take root.
1. Overcrowding Plants
It’s tempting to fill your garden beds with as many flowers and shrubs as possible, but overcrowding limits airflow, encourages disease, and causes plants to compete for nutrients. Over time, this leads to stunted growth and higher maintenance needs.
Fix it: When planting, always consider each plant’s mature size and spread. Leave ample space for roots and foliage to expand naturally.
2. Choosing the Wrong Plants for Your Climate
A tropical plant might look stunning in a magazine, but if it’s not suited for Pennsylvania’s weather, it won’t thrive for long. Many homeowners waste time and money replacing plants that can’t handle the local conditions. Learn more about how the right trees can help your property shine.
Fix it: Choose native or climate-adapted plants that are well-suited to Newtown Square’s seasonal changes. A professional landscape designer can help you build a sustainable, low-maintenance garden that flourishes year-round.
3. Poor Watering Practices
Overwatering is just as harmful as underwatering. Too much water can suffocate roots, while too little leaves plants dehydrated and weak.
Fix it: Use smart irrigation systems or drip lines to deliver water directly to the roots. Water deeply but infrequently, especially during dry spells, to encourage deep root growth.
4. Ignoring Soil Health
Even the most beautiful garden design will fail if the soil beneath isn’t healthy. Compact, nutrient-poor, or improperly drained soil prevents roots from absorbing what they need.
Fix it: Test your soil before planting. Add compost or organic matter to improve texture and nutrients, and ensure proper grading to prevent standing water.
5. Planting Too Close to the Home
Shrubs and trees planted too close to your house might look good initially, but over time, roots can damage foundations, and branches can scrape siding or block gutters.
Fix it: Give larger plants plenty of room to grow away from structures. This not only prevents damage but also improves airflow and light around your home.
6. Bad Grading and Drainage
Improper drainage is one of the most serious (and expensive) landscaping mistakes homeowners make. Poor grading can lead to standing water, soil erosion, and even foundation issues.
Fix it: If your yard collects puddles or drains toward the house, it’s time to call a professional. Greenstone Gardens specializes in drainage solutions that protect your property while keeping your landscape beautiful.
