Do you use organic sprays and fertilizers?

Yes! We use both organic and conventional sprays and fertilizers depending on the needs of your landscape. Our goal is to keep your plants healthy, vibrant, and safe while supporting sustainable practices whenever possible.

How often should I fertilize my lawn?

The frequency depends on the type of grass and soil conditions. Most lawns benefit from 3–5 treatments per year, timed with seasonal growth. We can create a customized fertilization schedule for your property to ensure optimal growth and color.

What’s the difference between landscaping and hardscaping?
  • Landscaping involves planting, caring for, and designing greenery such as lawns, shrubs, flowers, and trees.
  • Hardscaping refers to non-living elements like patios, walkways, retaining walls, fences, and water features. Most of our projects combine both for a complete, balanced outdoor space.
How do I choose the right plants for my yard?

Plant selection depends on sunlight, soil type, drainage, and your aesthetic goals. Our team can recommend native and low-maintenance plants that thrive in Connecticut’s climate while complementing your overall landscape design.

When is the best time of year for landscape installation?

The ideal timing depends on the project:

  • Spring and early fall are excellent for planting new trees, shrubs, and flowers because temperatures are moderate and soil conditions are favorable.
  • Summer is suitable for hardscaping, patios, and water features when soil is stable and construction conditions are good.
  • Winter can be used for planning, design, and certain services like snow removal.
Can I install a new lawn or garden myself, or should I hire professionals?

While DIY projects are possible, professional installation ensures correct grading, soil preparation, and plant placement — which leads to healthier, longer-lasting results. We provide full-service installation to save time and prevent costly mistakes.

What are the benefits of adding mulch to flower beds?

Mulch helps protect plant roots, retain soil moisture, suppress weeds, and regulate soil temperature. It also gives your flower beds a neat, polished appearance that enhances the overall look of your landscape.

How can I make my yard more drought-resistant?

Using native plants, proper soil preparation, mulching, and targeted irrigation are key. We can design landscapes that are both beautiful and efficient with water usage, helping your lawn and gardens survive dry spells.

Should I rake my leaves or mulch them with my lawnmower?

Both methods work! Mulching leaves with your lawnmower can return nutrients to your lawn, reduce waste, and save time. However, raking may be better in large amounts or when you want a clean look for flower beds. We can help you determine the best approach for your yard.

How do I get rid of weeds?

Effective weed control requires a combination of strategies: proper fertilization, mulching, mowing, and targeted treatments. Our team can assess your lawn and garden to develop a customized plan that reduces weeds while promoting healthy, strong plants.

Do you offer maintenance services after installation?

Yes! We provide comprehensive landscape maintenance, including lawn care, pruning, seasonal cleanups, tick control, and more. Our goal is to keep your property looking its best all year long.
