30 side hustle ideas
Fruit and vegetables from your garden
Sell what your garden or raised bed produces beyond your own needs: at the gate, at a farmers market or to neighbours.
First step: Start with a few high-yield crops (courgettes, tomatoes, berries) and offer card payment or an honesty box.
Watch out: Regular sales count as income; check how your tax office classifies them. In Germany: Regular sales count for tax purposes; the tax office decides whether they are farming or business income.
Microgreens and herbs on the windowsill
Microgreens and herbs grow in a few weeks in a small space and sell to restaurants, cafés and markets.
First step: Practise with growing trays and seeds for cress, radish and peas, then ask local restaurants.
Watch out: Selling food regularly usually means registering with your local food authority. In Germany: Selling food regularly requires registration with the local food control authority (Lebensmittelüberwachung).
Seedlings and plant cuttings
Cuttings of house plants and young tomato or pepper plants sell well in spring.
First step: Root cuttings in small pots, take good photos and sell locally.

Keep chickens and sell eggs
A few hens lay more eggs than a family eats, and neighbours like buying fresh eggs directly.
First step: Plan the coop, run and feed; ask neighbours and your landlord first.
Watch out: Many countries require poultry keepers to register, even with a few hens. Check the rules for selling eggs. In Germany: Register every flock, from the first hen, with the veterinary office (Veterinäramt) and the animal disease fund (Tierseuchenkasse). For direct sales, state name, address, best-before date and price.
Beekeeping and honey
One or two colonies in the garden produce honey for family, friends and selling from home.
First step: Take a course at a local beekeeping club first, then start with one or two colonies.
Watch out: Many countries require beekeepers to register their hives. Honey labels have legal minimum details. In Germany: Register your bees with the Veterinäramt. Honey labels need name, address, net quantity, country of origin and best-before date.
Worm farm on the balcony
Composting worms turn kitchen scraps into worm castings. Gardeners and anglers buy castings, worm tea and worms.
First step: Start with a wormery and a few hundred composting worms; the first castings come after a few months.
Watch out: Worms are live animals: pack them well and do not ship in hot weather.
Grow mushrooms
Oyster and king oyster mushrooms grow in a cellar or kitchen, for example on coffee grounds or straw.
First step: Practise with a grow kit, then inoculate your own substrate with spawn.
Watch out: Selling to restaurants or markets falls under food rules (registration, hygiene).
Declutter and sell your own things
Clothes, books, toys and gadgets nobody uses any more quickly turn into starting capital.
First step: Spend one weekend sorting room by room: sell, give away, throw away.
Watch out: Selling your own used everyday items is usually tax-free. EU platforms report sellers above 30 sales or €2,000 a year. In Germany: Selling used everyday items is tax-free; platforms report sellers above 30 sales or €2,000 a year to the BZSt.

Upcycle furniture
Sand, paint and restyle old dressers, chairs and tables and sell them as one-offs.

Watch out: Use solvent-based paints only with good ventilation.
Cakes to order
Custom cakes for birthdays, weddings and christenings are in demand and well paid.
First step: Build a portfolio by baking for friends, take good photos and price in all ingredients.

Jam, chutney and syrup
Fruit from the garden or market becomes long-lasting products for markets, farm shops and gifts.

Turn knowledge from your job or hobby into a video course: Excel, languages, baking, guitar.
First step: Pick one small, concrete skill, record 5–10 short videos and offer them on a course platform.
