|We've all heard of the decling bee population, so we decided to make a bee/butterfly garden - W/O ANY CHEMICALS, ETC. So we dug out 20+ year old Ilex's (and we never had one problem, they were perfect, just boring. So we planted a garden where they were. We had the stumps removed too but there are still straglers..... We planted loads of Rose Bushes (from H.D.) and lots of flowers, plants, etc. We used rubber mulch - big mistake - too hot and scorched alot of smaller plants.

So sorry to hear about your ongoing plant problems. The description doesn't point clearly to any one cause. My best guess is a root rot organism is affecting the plants. These are often brought on by soggy soil conditions but not always. Then there is the possibility of some root feeding insects such as grubs or wire worms.
You need someone to diagnose a plant sample or photos. I suggest you take a sample to your County Extension Office and see if they can identify the problem and if necessary prescribe an appropriate remedy. They may need to send it to the state lab so call them first to get instruction for what type of sample to bring in.
Thanks for the question. Please stop in again soon!
