Herbs are among the easiest plants to grow on a windowsill or balcony, and fresh cuttings cost almost nothing once the plants are established. The key is matching each herb to the right light and water. 100% Local
Most culinary herbs come from sunny, dry regions, so they want bright light and free-draining soil. A gritty mix with extra perlite suits rosemary, thyme and oregano. Basil also loves sun but prefers richer, more moisture-retentive soil.
Because their needs differ, it is usually easier to give each group its own pot rather than mixing them in one container.
Herbs are not heavy feeders, and too much nitrogen dilutes their flavour. A light feed every few weeks during the growing season is usually enough, and rosemary, thyme and lavender need very little at all.
Keep picking, keep the light bright and let the dry-loving herbs dry out, and a small herb collection will supply the kitchen for months.
Basil usually fails from cold, drought or too little light. It hates cold nights, wilts fast when dry and needs several hours of sun. Keep it warm, moist and bright.
With a bright windowsill or a small grow light, yes. In winter, growth slows and watering should be reduced.
For flavour, no. Pinch off flower buds to keep the leaves tender and the plant producing.
Soft herbs such as basil, cilantro and parsley are easy and cheap to raise from seed, sown in small pots and kept warm and bright. Woody herbs like rosemary, thyme and lavender are slower and more fiddly from seed, so buying a small plant is usually the quicker route. Whichever you choose, pot them into free-draining mix and give them the brightest spot you have. A windowsill that catches morning sun is often ideal for a small herb collection.
