Q&A
Can Horizon Landscaping handle both the design and construction of a major backyard project, including structures like an ADU?
Yes, absolutely. Our dual licensing as a Landscape Contractor (C-27) and a General Building Contractor ('B') is a key advantage for Pasadena homeowners. We can manage the entire process from initial landscape design and irrigation planning to the construction of hardscapes, patios, and permitted structures like Accessory Dwelling Units (ADUs) or room additions. This integrated approach ensures cohesive design, smoother project management, and a single point of responsibility for your entire outdoor living space.
We have issues with our Pasadena hillside property where a rock garden is shifting and the irrigation system leaks. Can you help?
Addressing hillside and irrigation challenges is a common part of our work in Pasadena. For shifting rock gardens or soil, we design and build structurally sound retaining walls to stabilize the area. For leaky or inefficient irrigation, we provide expert irrigation design and construction services, often upgrading systems to modern, water-efficient drip or smart controllers that prevent waste and are better suited to local conditions. We assess the root cause of both issues to create a durable, low-maintenance solution.
Do you work with drought-tolerant and native plants suitable for Pasadena's climate?
Yes, promoting sustainable and water-wise landscaping is a core part of our practice. We have extensive experience designing and installing gardens with California native and drought-tolerant plants that thrive in our local climate. This approach not only conserves water but also supports local ecology and reduces long-term maintenance. Our award-winning garden designs, some featured in Sunset Magazine, often highlight beautiful, resilient plant palettes perfect for Pasadena homes.
