Mahalo to our clients...

Janice Palma-Glennie's vision, knowledge, and dedication have made our home a place of extraordinary beauty. Five years from inception to present, the landscape has changed from weeds or barren areas to lush native and tropical. We receive continuous praises about our yard which has been featured in various  publications including Sunset. 

Mahalo Janice....

Alfred and Cathy Kuehlewind, I`olani

We have worked with Janice for over 15 years. She has helped us with landscape design on several houses. Janice is hard-working and reliable. She has great ideas for design taking into consideration water use, light variations, and how plants will mature for an overall workable and beautiful landscape. She also has great working relationships with many nurseries making it easier to get the supplies you need. Her installation crews are also hard working, skilled and respectful of your property. We highly recommend Keauhou Gardens and Irrigation. 

Aloha, Lyle and Kim Yeck, Keauhou

Love the site and all the beautiful spaces that you both help create here in Hawai`i nei! Thanks for all of your help on our property.

Carol and Scooter Fuller, Kailua-Kona

Janice is simply the best! She is a great listener, uncanny visualizer and brings a ton of knowledge and experience to each project. She is an honest, creative, hard worker and embodies the term “value proposition.” I highly recommend Janice of Keauhou Garden. She delivers! 

Carolyn Dillon, Holualoa

Alastair, the irrigation expert at Keauhou Gardens has helped us in many ways. He has designed a new system coordinating with landscapers and rock wall builders. He has repaired and tuned-up our system and altered a busy schedule to make time to do an emergency repair during a dry spell. We can vouch for Alastair’s expertise at maintaining landscape lighting systems as well. If you’re looking for an irrigation expert who knows his stuff, is reliable, fair and honest, we highly recommend Alastair at Keauhou Gardens.
