I've had mixed luck with keeping herbs alive over the winter. Thyme, sage, mint, and oregano seem to survive fine in the border next to the house and parsley usually comes back well in the spring. Plants like rosemary and French tarragon which would have survived over winter outside in England are less likely to do so here, so need some winter protection. The first winter, I dug up the rosemary plant and put it in the basement. Where I promptly forgot about it and it died of dehydration rather than cold. In the following year I took cuttings from its replacement and kept them in the kitchen, where I did remember to water them and they lived until the following year although the parent plant, left outside, did not. Last year, the rosemary plant I left outside did actually make it through the winter, although the smaller plants I kept in the kitchen did not. I'm just not good at remembering to water indoor plants...
But I am persevering and have taken four cuttings from the surprise survivor of last winter. I'm keeping these next to the kitchen sink in the hope that this will prompt me to water them more regularly...
Then I remembered the French tarragon plant I bought this year. I like tarragon but it's one of those annoying plants that can't be grown from seed, so I had to buy it from one of the local nurseries. I left it in its pot, thinking that it would be easier to bring it indoors in the winter that way. I went outside to find it and was rather disheartened by what I saw:
There are some small signs of life (if you look
very hard), so I've brought it indoors anyway in the hope that a spell in the warmth of the kitchen will effect a minor miracle and bring it back to full health. Gardening is all about optimism, after all...
