EspomaOrganic Holly-Tone 4-3-4 Natural & Organic Evergreen & Azalea Plant Food; 4 lb. Bag; The Original & Best Fertilizer for All Acid Loving Plants Including Rhododendrons & Hydrangeas. Pack of 2

My azaleas were browning and looking drab. I added this to the soil a couple weeks before they started budding and I had so many more buds than last year. I had a smaller azalea that never bloomed before this year. It's full of blooms after adding this fertilizer to the soil. The smell is pretty off putting, it's like manure. But the quality of the fertilizer is top notch! I'm definitely buying more for the fall.

I used this Holly-Tone and also Plant-Tone all season and my bushes and flowers did wonderful!! You have to pay attention and use the correct product on certain flowers or bushes. I will purchase this again, amazing results.

This was a re order. Used last year with great results on my rhododendrons. A bit expensive but I found that it is not necessary to use as much as the directions say. Great growth and the blooms were outstanding.

Good quality products.

This is the best fertilizer for shrubs, rhodos, evergreens and the Luke I buy it every year

Good fertilizer. Always use on hydrangeas.

This is my go to product for acid loving garden plants. However, these are only 4lb bags.

Fertilized my hydrangeas to keep the color. Easy to use.
