Raw, non composted cow manure vs. composted manure, for fertilizing an in ground palm.

Question

I have read recommendations for both methods.
What do you suggest I use.

Answer 1

The problem with raw manures will be that there may not be enough of a microbe count in your soil to break it down. This can leave it susceptible to infection, or too many nitrates that may burn the plant. I always recommend well-composted manure.

Some plants can handle it, uncomposted, but you will need to test a small amount beforehand. This will ensure that the plant does not have a negative reaction. Still it is best to use composted manure to rule out all doubt on the subject.
