Title: Care of Ixora by lowering soil pH
Answered by: Damon Waitt
QUESTION:
I have a bunch of Ixoras that the leaves are turning brown, before I pull them out, is there any kind of treatment to save them? I have used insecticidal soap several times but there has been no improvement. Thanks.ANSWER:
Your problem may not be insects. According to the U.S. Department of Agriculture, Cooperative Extension Service, University of Florida, IFAS, Florida A. & M. University Cooperative Extension Program, Ixora are acid loving plants requiring organic matter such as compost, peat moss, or composted manure to lower soil pH. Alkaline soils can result in poor health and poor foliage. To learn more, read about Ixora care on the IFAS Extension website.
