These are three years old we originally bought 14. 3 were replaced after the first year.   we have recently lost 2 more and now out of the blue 3 more are fading.

These type of spots come and go. We have been diligent about our watering and feeding with garrett juice. Are these spots disease, a watering or shade issue, or soil.

Thanks for any help you can give. Pics below.
