Hi orchard-andi and welcome. You don't say whether you have a patch of ground. If you do plant them out, pick the flower heads off as they appear for the best crop and they will multiply quite happily. When the clump gets too large dig it up in the autumn, divide it and replant. Chives freeze very well as they are so when it starts to cool down, chop the green bits off, chop up if you want and freeze. The rest will die down over winter and regrow in the spring.
