Hi all! I have a sage plant (common sage) that I bought in early May of this year. It was about 4 inches tall when I got it at a local home improvement store and it's about 6 inches tall now. Not much change for late July. This poor plant probably just wants me to leave it alone. Not too long after I got it, my pineapple sage that I got at the same time, began turning brown and dying. I'm pretty sure I was overwatering. I wasn't able to save that one, but my common sage and rosemary survived. Shortly after the pineapple sage got sick, so did the common sage. At first I thought it was still because of too much water, but I'm sure now I've given it ample time to dry up a tad in between waterings. The planter that the sage and rosemary were in was a large rectangle shaped plastic one that had a tray on the bottom to "auto water." I popped the tray off to increase drainage. They sit all day on our west-facing patio so they get mostly evening sun. Which in Oklahoma is HOT. The rosemary continued to look fine but the sage didn't. Basically, most of the larger leaves at the top of the small plant were okay, give or take a couple. The small young leaves at the bottom are the worst. Every day when I wake up in the morning, I check it and more baby leaves are completely brown and wilted. So I pluck them off and throw them away. When I come home from work in the afternoon? Same thing. Two nights ago, after the evening cooled a bit, I uprooted both plants as gently as possible and added some sand and this pearly decorative gravel (it was the only thing I could find at Home Depot) to the soil and replanted them. The good thing is, there has still been more new growth and no loss of an entire stem. I'm worried because it seems like it's getting worse. I know drainage is a really key thing in herb gardening, especially for Mediterranean natives. The sage's roots were extremely bound, so much so that I couldn't get all of the old soil off. They're still in the shape of the little plastic thing the baby plant came in at the store. I didn't want to do too much root damage so I left it. There is plenty of root growth beyond that on both plants so I thought they might need a deeper container. I bought two deep 10 inch containers and planted them each separate, adding a little humus and manure compost, a bit of peat moss and some more gravel to compensate for the addition of dense material. Sorry this is getting so long but I'm trying to be thorough.
Daily, about one or two larger leaves will be affected, turning brown on just part of the leaf like a half moon shape on one side. Here is what I have observed in the plant's short history as far as pests: A couple of little green worms about an 8th inch long. I plucked those off and haven't seen any more. A few ants in the planter a while back, but haven't seen any in a month or so. On the bottom of some of the leaves, I have found, total, about 5 ot 6 of these teeny tiny white things that look like the shell/skin of an aphid. Could they be whiteflies? Just one time on a single leaf, I found this sort of irridescent substance that looked slimy but it was dry. I wonder if that's the product of a whitefly. But that was only one time. I've gone out in the middle of the night to try and catch a night crawler of any kind and found nothing. I've looked at it with a magnifying glass to try and spot any mites. Again, nothing. In the last week or two, the leaves, especially the larger ones have started curling. Not curling up, but curling in a downward spiral with the bottom on the inside. Since I repotted with the humus and manure last night the leaves have straightened out a bit but I think both the sage and rosemary suffered a little transplant shock from me messing with them two days in a row. They got a tad wilty. I think that will subside though once they rest and grow accustomed to their new soil. Any clues would be much appreciated!!! Thank you!!!
