Espoma Organic Holly-tone 4-3-4 Natural & Organic Evergreen & Azalea Plant Food; 18 lb. Bag; The Original & Best Fertilizer for all Acid Loving Plants including Rhododendrons & Hydrangeas.

My plants really thrive on this.

This stuff is great for my blueberry bushes. Feeds over time.Upon opening the box, there was a small amount that leaked from the bag from a small hole that failed to seal from the factory.Material stuck in the seal area prevented adhesion and left a quarter size hole.Not sure how much was lost, but no big deal. Not worth fussing over.Life's too short. Still gave 5 stars.

Hollytone is simply amazing when used on rhododendrons and azaleas. We had a small rhody that had not flowered in 4 years. I was spindly and hadn't had any new growth although it wasn't losing many leaves. Sadly it was in jeopardy of leaving our flowerbed and going to plant heaven.Online, it appeared that Hollytone might be able to revive it, so I bought a 4 lb bag and applied it that fall. Six months later as spring began, I applied more per instructions. Several weeks buds started appearing. By summer it had bloomed for the first time in 4 years and had many flowers.

I use this product every spring and late summer on my acid loving plants....they thrive on this stuff - I do not use anything else on my plants....

This price was not a bargain. It was cheaper at my local nursery. The product is really good and easy to use. It was the price that caused only four stars

Have not used yet, but will let you know soon how it works. I received this product in a very timely manner

I have been using Holly Tone for years, my neighbor asked me why my arborvitae were twice the size of his when we put them in weeks apart 10+ years ago. Mine are 7-8 feet tall and very nice size around. His are maybe 5 feet and skinny. Same plants, came from the same place, the only difference is I feed Holly Tone twice a year, once for the winter and one in late spring.

I use this always and it keeps the azaleas blooming. They are encore ever bloomer and they bloom throughout the year in florida
