My garden is loving the Wonderfert
Wonderfert is absolutely incredible! I had a rose bush that was practically dead — wilted, brown, and barely hanging on. After using Wonderfert, not only did my rose bush bounce back with new growth and beautiful blooms, but my entire garden exploded with life! Everything is growing bigger, stronger, and healthier than I’ve ever seen before. It feels like every time I step outside, my garden has doubled in size! I’m so impressed with the results, and I’m officially a loyal customer have been for two seasons now. If you’re serious about bringing your plants to their full potential, Wonderfert is a must-have!
Was this review helpful?I’m attaching two of my
I’m attaching two of my rose bushes purchased at a local Hardware - marked down due to bug infestation and black spot. Much of both bushes had to be cut back, 'groomed' to remove diseased leaves & reshaped. Sunday’s Flower & Rose Organic Garden Nutrients was the only product used following the instructions. It's 10/24/23 and they are still so very healthy, blooming & lots of buds about to open ...enough said; this will be used again in Spring 2024
Was this review helpful?Not worth the price
I decided to add this to our order because we’ve been so happy with the lawn care products and the reviews were all great This was very disappointing. First, the provided nozzle was spraying a small amount out the side which I couldn’t fix so it was annoying to lose a little product that way while applying. Second, there’s no way to slow down the application and the bottle emptied fast. The only good thing is that I can refill the bottle with Miracle Grow although the nozzle is so annoying that I may not. It has been a little over two weeks and I don’t notice a substantial difference to any of my flowers or plants.

Hello Shelly, we’re really sorry this one missed the mark, and that nozzle issue sounds especially frustrating. That’s definitely not the experience we want, and our team can help troubleshoot or make it right if you reach out. We appreciate you giving it a try and sharing the honest feedback with us.

Was this review helpful?WonderFert Flower Garden Fertilizer
This product was amazing and easy to use! I noticed a big difference when using this fertilizer on my flowers because they were brighter, more colorful, greener, and just looked healthier. I would use this product again and again.
Was this review helpful?Fading foliage regenerated
My flower beds have started to fade over the years. Used the common miracle grow fertilizer and it never seemed to bring everything back to life. This is the first time I've used the wonderFert flower fertilizer and so far the foliage on my perennials is looking much greener than it has the past few years and peonies have a much fuller bloom. Ordered more of this to see the impact using for a full growing season.

This is my first time taking care of flowers, and I feel that this Sunday product is great for beginners as the organic base makes it very hard to harm a flower. Instructions are clear, and my roses look great.

Question: Why is the flower garden kit restricted in my state of California?
Louisa D.
At this time, this bundle is restricted in California due to the Soil Boost product included in the kit. This product is not available in California due to labeling regulations, but we hope to offer this product in California in the future!
Question: How do I use the flower soil boost with a cloth barrier? My flowers were already planted 2wks ago before I heard about you.
