Frequently Asked Questions

Why do I need to do grade work before starting my new landscaping?

Proper grade work is the foundation of every project. At KJ's Green Thumb, we perform grading to manage water runoff and protect your home's foundation. This essential prep work ensures your new sod and plantings don't suffer from erosion or poor drainage.

When should I choose a pondless waterfall over a traditional fish pond?

If you want the soothing sound of moving water without the maintenance of aquatic life or cleaning filters, a pondless feature is ideal. Our experience at KJ's Green Thumb shows these are perfect for smaller yards or families seeking safety and simplicity.

What's the difference between seeding and sodding for a new lawn?

Sodding provides an "instant lawn" and immediate erosion control by laying mature turf. Seeding is more cost-effective but requires patience and specific timing. KJ's Green Thumb & Landscaping offers both, typically recommending sod for projects requiring a finished look within a day.

How does the hardscape design process work for a custom patio?

We start by analyzing the "natural lay of your land" to ensure structural integrity. We then help you select premium pavers or stones. KJ's Green Thumb focuses on building features like sitting walls or fire pits that flow naturally with your existing topography.

Why do I need to visit the supplier like Kings to verify block and stones?

Seeing materials in person ensures the color and texture match your vision before delivery. KJ's Green Thumb & Landscaping recommends this step because natural stone varies; selecting your specific materials prevents surprises and ensures the final aesthetic meets our high quality standards.

How long does it take to install a professional outdoor lighting system?

Most residential lighting installations are completed within a few days, depending on the number of fixtures. We carefully trench wires to highlight your landscape's best features while ensuring the system is durable enough to withstand the changing Iowa seasons.

What factors affect the cost of a new retaining wall?

Cost is driven by the wall's height, total length, and the specific blocks or stones chosen. At KJ's Green Thumb, we also factor in the meticulous prep work-like gravel and sand bedding-required to ensure the wall remains perfectly level and stable.

Why do you require an appointment for Saturday consultations?

As a personalized operation, Kevin takes a personal interest in every project. We operate "By Appointment" on Saturdays to ensure you receive dedicated, one-on-one time to discuss your goals without the distractions of active job site management.

Can you install a water feature in a very small backyard?

Absolutely. We specialize in designing decorative fountains and small-scale waterfalls that fit into compact spaces. KJ's Green Thumb can integrate these "final touch" elements into almost any garden layout to enhance the serenity of your outdoor living area.

How do you ensure my new plantings survive after installation?

We use more than three decades of experience to select greenery that thrives in local soil. Beyond planting, we offer tilling and mulching to lock in moisture. KJ's Green Thumb also coordinates with irrigation specialists to ensure your new investment receives proper hydration.
