Very pleased!

Would Recommend

This Garden Tone fertilizer is fantastic for my flowers! Its balanced structure really boosts root development and overall plant health. I apply it directly in the planting holes and mix it into the surface. My flowers are thriving—I highly recommend it for any garden!

It works!

Would Recommend

I got the idea from Laura of Garden Answer. I have perennial ferns and lipriosa grasses planted and only a few looked like they were coming back, with the rest just "surviving". After using the Bio-tone, they are all coming back strong. I bought it to use for starting plants when I planted a couple replacement ferns, but I'm glad I also used it around my existing plants. I've been missing out not knowing about this fertilizer but I will be keeping it on hand now. Highly recommend!
