If you cook a lot in my opinion growing herbs is a must. Not only does it save money but homegrown herbs are so much better. I grow several varieties of mint, thyme, parsley, sage, rosemary, coriander, several types of basil, lemongrass, bay tree (and you will not believe the difference in a fresh bay leaf from the sad dry ones!), fennel, dill etc. Some are potted, some in raised beds, some in the garden.
As to what to do with them I just roll with the flow. Many self seed, some are seasonal, I collect seed and use this too. Fresh coriander seed is amazing unlike the seed in the supermarket spice section which has probably been sitting there for months if not years!
Dry the mint and make mint tea. I could go on forever on the uses of herbs. But as a general rule fresh is best and many lose flavour when frozen.

I freeze all my excess herbs and thaw them to use for later

I believe that some of these can be frozen…or dried…

You could see if there is a produce cupboard nearby some neighbourhood has these and you can put in your excess produce and neighbours do the same then everyone wins.

You can freeze lots of herbs. Just have a google or give them to neighbors

I never again put mint in my garden. Can’t get rid of it. Luckily we moved.
Not really herbs I use often. I would put parsley or basil in. There are some techniques to try herbs. Just google and see if that’s an option.

Mint will completely take over if not potted separately!
Dry the herbs out and store, give away to friends and family.

Swapping and trading with family, friends and also work colleagues is a terrific way to stop any waste.

I love using loads of rosemary when I roast vegetables. I dry my own. You could make mint jelly (sauce) or add it to your water to use it daily.

Lemon grass and mint are lovely for tea’s. You could dry the rosemary and thyme and put them in a glass jar as a wee gift

Make sure your friends know which ones you have so they don’t buy them and enjoy sharing. You can dry some excess to use or give away as well.

I give extra produce away.

Uproot the mint and pot it before your entire yard is taken over. It’s a creeper. If you’re looking to use them you can make fragrant cooking oils with the rosemary and thyme. Or chop the herbs up really finely and put them in ice trays with either oil or butter and freeze for flavour bombs in meals. I love rosemary and would probably use cuttings in the house for scent purposes.

I have found mint and rosemary need to be kept in pots this will eliminate too much growth. Have you considered planting them in the garden in pots to keep them from over growing?

For woody herbs like rosemary, prune lightly after flowering to maintain shape and encourage new growth. Plant lemongrass and mint in pots to prevent them from spreading. Divide overgrown clumps of rosemary and thyme to manage their size. Frequent snipping encourages bushier growth and keeps them in check. Use the bounty in cooking or dry for later!
