I ordered this in summer for my roses, even though it said for palm trees roots etc. I have tried alot of different types of these fungi's but this one did the trick. I have four semi gardens at my home, some with perennials and annuals and i applied this on the east side of my house which gets the least sunlight. It took four months but they have never looked this healthy and green with beautiful flowers. Now what used to be my "experimental side" has now turned into my good side. I do not like writing reviews but I feel that gardeners should know this. The product is somewhat pricey but well worth it, in my opinion.
