Some background information...

How long has the plants been planted? If just recently, did you buy them as trimmings or as already fully grown plants with root systems?

I found that if I bought stem plants which are trimmings, and trim them too early into planting them, they tend to die off. If you allow them to develop a strong root system for the first 1-2weeks before trimming, they usually do fine.
