Whether you're maintaining a front-yard flower bed or a sunlit windowsill, ColorStar helps your plants thrive with minimal effort.
Easy to apply and slow-releasing by design, ColorStar supports strong root systems, enhances bloom cycles, and improves overall plant resilience. It’s the go-to fertilizer when you want your garden to shine from early spring through the end of the growing season. With ColorStar, you’ll see the difference. Feed less. Bloom more.

Wasn’t blooming

My Mandeville was growning but only putting out one bloom at a time. I went to a local nursery and they recommended a plant food. I had two choices and I picked Nelson Color Star. I made the right decision! Just what my plant needed.
