Resurrecting Rosemary and Lavender

Resurrecting Rosemary and Lavender

Hello, everyone. I live in Alabama (Zone 7) and we've been having some very hot, dry weather this spring. I was abroad for a month and asked a good friend of mine to stop by my house once a week to water my balcony garden (lavender, rosemary, sweet basil, Thai basil, German thyme, spearmint, cherry tomatoes, grape tomatoes, sweet peppers, and various succulents) and check on my indoor orchids (Cattleya, Phalaenopsis, Dendrobium, and Oncidium). As you might guess from my subject heading, I returned home this week to several dead plants on my balcony, others clinging to life, and a houseful of wilted orchids. After a brief mourning period, I set out trying to salvage what I could. The tomatoes, peppers, and basil were all lost causes, but my thyme, mint, and succulents are all recovering nicely. My orchids are also doing well after being repotted. My rosemary and lavender, however, are still struggling. The lavender had flowered in my absence, and looks quite depressing now, mostly gray and brittle. However, there are some green leaves still on the stalks. My rosemary is another story. All of the foliage is brown and easily shed. I cut one of the stems and found that it was still green and moist. So, enough with the dirty details. Is there any hope for either my lavender or my rosemary? Is there anything I can do to help them along, in addition to watching and watering them carefully? I appreciate all of your help!
