Cottonseed Meal is useful in a low-pH soil with low-pH requiring plants. It’s reputed to be great for roses, azaleas, rhododendrons, and potatoes.

    With a combination of Bloom Pack and Cottonseed Meal, my roses performed much better even when the heat arrived in South Texas. I also applied this to my gardenia, crape myrtles and hibiscus plants. They love it!
