 San Diego Specialty Plants & Gardens

Open Monday-Saturday 8am-5pm

Sundays 9am-2pm

Waterwise Botanicals is more than a nursery and welcomes both homeowners and the landscape trade industry. We are always striving to assure convenience and confidence as we continue to offer quality and diversity of plant material. We have acres of beautiful nursery and growing grounds, including demonstration gardens, ponds, and a shade house full of creative treasures to inspire you.


We invite you to come and explore our location out in the country away from the stresses of daily life. We like to describe ourselves as having a touch of “rustic elegance”. Take time out to sit in our gazebo in the Cottage Garden, or bring a snack or lunch to enjoy at our picnic tables near our ponds.

Tom talks science!

October 30, 2025
Did you know compost can reach temperatures up to 160 degrees?  That’s right! In this video, Tom Jesch from Waterwise Botanicals shares some fascinating science behind why compost gets so hot. It’s all thanks to the millions of micro-organisms hard at work! These living organisms feed on nutrients—like nitrogen—and act like tiny engines, generating heat as they break everything down. It’s very similar to how our own bodies work: we eat nutritious food that feeds our billions of cells, which then produce body heat around 98.6 degrees. We love sharing these fun, science-based insights and our passion for the natural world with you. Watch the full YouTube video here! To learn more and experience the magic of nature firsthand, come visit us at: Waterwise Botanicals 32151 Old Hwy395 Bonsall, CA 92003 Open to the public 7 days a week! Monday-Saturday 8am-5pm and Sundays 9am-2pm Free admission and free parking!

Tom talks fertilizer!

October 30, 2025
The three main ingredients in fertilizer are nitrogen (N), phosphorus (P), and potassium (K)—often referred to as NPK. These essential macronutrients each play a key role in plant growth: nitrogen promotes lush leaf growth, phosphorus supports strong root development, and potassium enhances overall plant health and resilience. Join Tom Jesch as he dives deep into the world of fertilizer! Learn the difference between organic and non-organic options and discover which type is best suited for your garden and your plants’ unique needs. Watch the full YouTube video here! To learn more, come and visit us here at Waterwise Botanicals! 32151 Old Hwy395 Bonsall, CA 92003 We are open to the public Monday- Saturday 8am-5pm and Sundays 9am-2pm. Always free admission and free parking!

A Plant Nursery & Nature Experience

It’s been said, we are a “Plant Lover’s Paradise”, so as you wander our growing grounds under the beautiful skies, in the hills of North County San Diego, discover the intriguing beauty of our drought tolerant selections and much more… Enjoy the diversity of succulents, or the structure and dynamic impact of cacti. Walk through row upon row of romantic roses and see the dance of ornamental grasses in the breeze. Delight in the grace of colorful perennials, and explore our shade house, a wonderland of fun, gifts and temptations.

Waterwise Botanicals is a place to dream and adventure… wear your comfy, but sturdy shoes and bring a camera to capture the ambiance of our unique nursery, rich in wildlife and nature. You are likely to see birds, and lizards, along with fish and frogs in our ponds. Occasionally, a turtle or two will climb out on a log to sun bathe. We are a working, growing, evolving nursery, so you will observe workers in the fields, or tractors loading plants and mixing soil, making your visit much like the fun of a field trip!
