Matthew's Journal

I have never had any trouble with any of the above being susceptible to frost. Mint is a perennial and will die down over winter, but will come back again in the spring. Mint will really take over a garden and will propagate from a small piece of root, so definitely keep this in a pot, we do. I have recently planted some sage and it is fine so your plant is probably just suffering from recent re-potting. Don't let them dry out too much (essential when keeping them in pots), but also don't keep them too wet. If keeping them in pots for a long period, they will need feeding as they will use up all the nutrients in the soil. You can get these in pre-measured doses according to the size of the pot. If they have just been re-potted into fresh soil, they won't need feeding for this season.
