I have two groupingss of three gardenia radicans in my front borderlandscaped two years ago. In each group two are doing well while the third looks pretty sick after losing lots of leaves. I fertilize them with Miracid and have given them ironite on the advice of a Master Gardener friend of mine. Why would four do so beautifully and two other in the same soil, next to the others, fed and watered exactly the same wither and are ready to die. I lost one under the same circusmtances last year and replaced it this
spring. It's doing just fine.
Any advice?
Thanks!
