Q.In one corner a hydrangea – honeysuckle. And one other shrub have all suddenly died off – what is the cause?
The grass is fine. It’s growing in the vicinity of a privet hedge and a wisteria – any suggestions please?

It would be important to examine the leaves of the plants that died to see if there is a pest they have in common, one that may have traveled from one to the other. If you can't identify anything common on the stems and leaves, such as spots or browning, there may be something destroying the roots. Please take samples of your plants to your local extension service or nursery expert to see if you can get to the bottom of the problem before it causes any further destruction.
