Seems like I heard on a gardening show that cottonseed meal is good for azaleas. Anyone know about that?

Thanks,

Carla

If your azaleas are showing signs of needing supplemental fertilizer (they are not heavy feeders), cottonseed meal can be a good organic source. It releases nitrogen more slowly (minimizing risk of burning plants), providing a weaker stimulus that remains effective over a longer period of time.
"Cottonseed meal is a by-product of cotton manufacturing. As a fertilizer, it produces a somewhat acidic reaction; consequently, it is frequently used for fertilizing acid-loving plants such as azaleas, camellias, and rhododendrons. Formulas vary slightly, but generally, cottonseed meal contains 7 percent nitrogen, 3 percent phosphorus, and 2 percent potash. Nutrients are most readily available to plants in warm soils, but there is little danger of burn."

Yes, all your Azealeas need is some cottonseed meal and garden sulfur.
