I can sympathize with loosing prized plants. I tried almost everything Here is the short list of what helped me get back many plants and flowers that I hadn't seen in years.
1. Motion detector sprinklers.
2. I also spray the perimeter of the property 3' wide with horticultural oil mixed with horticultural vinegar. That lasts for several weeks.
3. Plantskyyd. The money I have spent on plants is well spent on this product . I use the Plantskyyd pellets during spring thru summer. 4 large buckets all season. $120.00 total to save all my plants. Most plants when added up are worth far more. The pellets last for weeks and last longer. Plantskyyd has saved many plants from the destructive jaws of the deer and antelope that come from the forest next door .
Since using Plantskyyd many flowers like roses, hibiscus, grapes, trumpet flowers and more have all returned. Spring thru fall. Many are back that I haven't seen in years even a few daylilies, some are back healthy and blooming since using Plantskyyd pellets.
