Great for Holly tree and Holly bushes. Easy to use and great results.
We used it on our 25 yr old Holly tree and Holly bushes. They greened up fast and bright red berries now!

Happy Hollies
I have quite a few holly bushes and I use this on them every spring. My bushes stay bealthy, grow wonderfully and the females are heavy with berries. You owe it to your hollies to apply this every year.

The Secret Elixir of the Garden Realm
If my azaleas could talk, they’d be singing show tunes right now. Espoma Organic Holly-Tone isn’t just plant food—it’s a spiritual awakening for anything with roots and dreams of grandeur. I sprinkled this around my rhododendrons and woke up to a scene that looked like Mother Nature herself had dropped by for brunch. It’s long-lasting, slow-releasing, and just the right kind of organic magic. The scent? Earthy enough to make you feel like you’ve accomplished something profound, even if all you did was scatter granules in your pajamas. Five stars. My evergreens are standing taller, my hydrangeas are blushing with pride, and I’m one application away from being appointed the neighborhood druid.
