Is It OK To Pile Up Plant Waste Material Around Banana Trees Treating It As A Mulch?

Question

I have heard it is not a good idea as it removes nitrogen during the decomposing process? Can anyone please advise. Thankyou

Answer 1

Organic mulch, such as leaves, bark, grass trimmings, wood chips or other materials that could potentially be composted will help the tree and add nitrogen to its soil. Waste material that's not compostable would not be helpful.
