Hi Jim: always good to hear from you. I use 1/2 cup of cracked corn, but I soak it in a bucket of water overnight to soften it. The water has nutrients for the rose, I cover the softened-corn with dirt so birds can't eat it.

There's a hole which I put 2 cups of crack-corn right before last Thanksgiving. This 1st week of June I planted 18 baby-tomato plants, the tomato in the hole with decomposed-crack-corn has 2 fruits, the rest haven't.

Thanks Straw!
