Q.Dying plants in flower bed

Zone 77059 | Rare3 added on September 25, 2016 | Answered

I live in hot Houston. Over the last few months some of the plants on one side of the landscaping flower bed are dying off. I’ve lost a large hibiscus plant, multiple rose bushes, and some red tips. What is going on? I don’t see any obvious bugs. etc. and it’s well watered and evenly fertilized. Any advice, please?

If these plants were new this year or last year, they may have died from transplant-related damage or because their roots failed to establish well in the soil. If these were shrubs that had already been in the bed for several years, look for other causes.

Since the plants you lost were of multiple different species, I would suspect animal damage. Animals could have stripped bark off the base of each shrub and severely injured or girdled it, or voles could have attacked the roots:

There is one disease called Verticillium wilt that can attack all the plants you mention, but this would have caused noticeable symptoms before they died:
