|I have put rubber mulch in my flower gardens of marigolds and petunias and it has killed them all. Is this mulch not recomended for these types of plants, vegetable and house plants.|
I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
That is very strange because those types of mulches have been used around a variety of plants without problems. There must be something unusual going on there in your flower beds. I just can't figure out what the problem might be, or how it would be related to the mulch.
I'm sorry I could not be of more help this time.
