I had a really great experience here. I'm brand new to gardening and RD spent a lot of time with me helping to pick out what I should plant, how to care for everything and providing a ton of other helpful information! I will definitely be returning!!

New to San Diego county and of all the nurseries I have checked out so far (and I’ve gone to A LOT 😂😂), Green Thumb is by far one of my favorites. Great quality plants, new stuff to check out every time I visit. Love the perennial six packs and the huge selection of calibrochas. Love everything about this place. One of the best and cutest bathrooms too.

Green Thumb Nursery is my favorite plant nursery. It has a wide variety of quality indoor and outdoor plants and all the garden accessories you could want or need. The plants I’ve bought there are thriving and my kids love to come along too because of the fun and beautiful atmosphere. I highly recommend Green Thumb Nursery for all your gardening needs.

In our area North San Diego county Green Thumb is the only real garden center with everything needed, people who know what do and how to do it. They know the answers to our questions and they have very sharp folks that work with their customers. 😊

I can’t say enough good things about Green Thumb Nursery in San Marcos. Their plant selection is incredible—healthy, diverse, and thoughtfully curated. The pricing is more than fair for the quality you get, and in many cases, far better than what you’d find elsewhere.What really sets them apart, though, is the staff. Every employee I’ve interacted with has been knowledgeable, helpful, and clearly passionate about what they do. Whether you’re a seasoned gardener or just starting out, they take the time to guide you and make sure you’re getting exactly what you need.Everything I’ve brought home from Green Thumb has thrived. I recommend them to anyone and everyone looking for anything garden-related—and I always steer people away from the big box stores. There’s just no comparison in quality, care, or experience. Please see the below, photos of broccoli, subsequently replaced by cauliflower, beets, radishes, carrots, fava beans And even some California poppies just for fun in my raised bed in our community garden.

My grandson and I spent hours enjoying our day shopping and looking at all the beautiful plants trees, and scrubs. Our goal was to make a fairy garden, There is a wide variety of ornaments to decorate and choose from. My grandson said it was so fun at the garden center we are going to make it a monthly visit. We will post a final picture of our fairy garden when we finish it. 💐🤩 update! We finished our fairy garden! We love it. Now we are going to write a fairytale about it. Something for the grandchildren to treasure. ❤️

Went to Green Thumb nursery over the weekend to re-stock my milkweed supply. Fortunately they had plenty to choose from and it was easy to find. Lovely nursery that allows you to stroll through the plants and flowers. A nice way to spend an afternoon.

As a longtime customer of Green Thumb Nursery-San Marcos, my husband and I knew we had the most quality and customer service oriented spot for everything garden related!After becoming a UCCE Master Gardener in 2023 and starting the volunteer/consultant role with school gardens, I realized that Green Thumb is even more valuable to me!My shout out is to Cathie, who knows that I am a Master Gardener and she absolutely sees if I need help or have questions.Could I feel more at home at this abundant and resourceful garden?Nope! Cathie and other GT staff are the reasons I shop here for my school gardens as well as my own personal gardens! Kudos to all things green!

I was amazed at the variety and selection of plants at Green Thumb. I was specifically looking for herbs and vegetables and did my best not stray away and look at everything, as I could have easily spent hours looking at everything. It was beautifully organized and all of the plants were really healthy. I also found the pricing was much better than Lowe's or Home Depot. Can’t wait to go back and look around!
