I do strongly encourage everyone to grow their own herbs and chilli peppers! It is so easy to do. I’m horrified at the price of herbs.
You can ask for plant pots on free cycle - many gardeners will have some to donate. Buy a pack of compost and that’s all you need to get started.
Ask online local groups of friends if they have cuttings of rosemary and sage in spring - I always have a few cuttings potted up and ready to give friends who show an interest!
Herbs do well in pots. I have two flourishing thymes in 8 inch diameter pots (a lemon thyme and a common thyme). The thyme in the ground got so enormous my dh pulled it out because it was taking over!
I am lucky to have a house so I can put pots in sunny spots and also have some plants in the ground but a sunny balcony works too.
In Year One, Start with thyme, sage and rosemary. These are perennial and bushy and need to be chopped back annually - you’ll have mountains of herbs to use and dry for the winter and early spring before your plants sprout again. Drying herbs is easy - just spread out on a tray in a warm dry place.Save any jam jars or other screw top pots to keep your herbs in. Stuffing balls made with your own dried sage are a blessing in winter!
Then in year two, get some garden mint - I’ve always had to buy a starter plant but it’s worth it. If you get mint established it will run wild, so watch out (best in a large pot).
Your other herbs you will likely grow from purchased seed: coriander, dill, parsley, chives and cress are easy to grow. Chives should be perennial if they can grow big enough and get pollinators to reseed themselves.the flowers are so pretty and attract bees. I find basil and oregano is tricky to grow but not impossible.
My local library does a “free seed basket” and people donate surplus seeds -the librarian puts a pinch of the seeds into little twists of paper so you can take a small amount -ask if they can set one up!
Early in the year, rocket also grows well in a large pot. You can let it run to flowers and leave it until the seeds pods are brown/dried out as the weather warms up, and harvest the seeds for next year’s planting. You can also try other things you’d not find in Tesco like mizuna and sprouts.
Same with chilli’s: they do need heat and pollination so once the plants are establish get them in full sun. A chilli plant can last for years - my mum had one on a sunny windowsill that kept going and going. So bring it inside for winter and either pollinate with a little paintbrush or leave a window open nearby. Leave a couple of chilli’s to ripen and dry and voila, you have seeds to start more plants next year. My brother accidentally grew 13 chilli plants one year as every one survived and was eating dried chilli’s for a long time!
In the past in other homes I’ve managed to grow tarragon (perennial but died off in a harsh winter), lemon balm, peppermint, borage, chilli, garlic chives, garlic. All sorts of amazing plants and often beyond what you can buy on a supermarket shelf!
You don’t need as much space or talent as you think for this and it’s addictive, great for our insect populations and saves you money.
