The only place in the house I've ever managed to overwinter rosemary was when I had one in the window next to the kitchen sink. It was rather weak by the end of winter since I didn't give it extra lighting and the light in winter here is rather meager. People and houseplants alike have difficulties because of the lack of sunlight we get in winter!

Anyways.....any of the other rosemaries I've tried to overwinter - all kept in other locations, died. They turned crispy and died. I suspect the humidity, which the kitchen is one of the more humid places in the house, might be key to their indoor winter survival.

Try submerging the pot (not all the way to the top) for awhile to insure that the whole soil volume is getting wet.

You absolutely should never have to fight with a potting mix in order for water to infiltrate all the way throughout the pot, before it exits the drainage holes.

What kind of potting mix are you using? Believe it or not, I'd actually like to see a picture of the mix AND the plant.

The rosemary bushes have since died, and when I pulled up the root balls, the soil was perfectly moist. Not dry, not wet. I have no idea why they didn't survive. The soil was draining well as evidenced by the fact that there was finally drainage out the bottom a few days ago.

I had been using river rocks as mulch to increase humidity which seems to work just fine on my gardenias in the same room, though they are the closest ones to the windows.

I've no idea how to post a picture, but I will attempt to upload it if I can. If not, I'll send another post with a link to my snapfish.

Thanks for the help!
