Just moved to Texas from Maryland about 18 months ago, so this is my second spring season here. All the hot climate plants here are foreign to my east coast green thumb, and I apparently made a mistake with my prostate rosemary bushes last year. When we bought our house, there were several very overgrown rosemary bushes, so I asked some neighbors how to prune them back to a manageable size. Basically, I was told you could not kill these plants, so I pruned all the dragging tendrils back, leaving about a three-foot diameter bush -- about 1/2 the original size. There was only a little growth last year, maybe 6 inches or so. This year, the old growth on the bushes is grey, with only a few tendrils on the undersides that are green. Other rosemary bushes I've seen in the downtown area are already bright green. The house (and these bushes) are five years old. They are on an underground automatic watering system, and receive 15 minutes of water once or twice a week, depending on the season. I fertilized them once last season (heard herbs don't need much fertilizer) with Ironite and MirAcid, since our soil and water are alkaline. Are these rosemary bushes gone-ers? Any suggestions from you Texans as to how to help these plants?
