The same technique can be used with clumps of mint dug up from the garden.
Ensure the clumps are filled around them with compost and make sure that at the top of the pot, you’ve left half an inch to an inch gap to allow for watering.
Over the winter months, the pot can’t be put outside but should be placed in a space where temperatures remain above freezing.
Alan explained: “What you’re going to do with this is to sit it not outside but in a porch [or] in a cool conservatory.
“It doesn’t need tropical heat it needs to be just above frost [level].”
