Hi Tim,

Thank you so much for taking the time to share your experience with the Fertilome Root Stimulator! We’re thrilled to hear it’s helping your new plants establish strong roots quickly and thrive after transplanting. It’s always rewarding to know our recommendations make a real difference in your gardening success — especially when combined with your careful care.

Since you’re using it so frequently, a little tip: apply the stimulator when transplanting in cooler parts of the day, like early morning or late afternoon, to maximize absorption and reduce stress on the plants. Also, rotating with a balanced fertilizer as plants grow can support sustained health beyond those critical first weeks.

thanks again for trusting us with your garden — if you ever have questions or want tips on new plant arrivals, feel free to reach out. We’re here to help!
