Herbs on the Windowsill: What to Choose and How to Cut

Herbs are the perfect gateway to urban gardening: they fit on a windowsill, grow fast and give you fresh flavor year-round. With a pot, sun and regular watering, you'll have basil, parsley or mint on hand — no more buying bunches that spoil in the fridge.

The easiest ones to start with

Herb	Light	Notes
Basil	Full sun	Annual, very productive; pinch flowers
Parsley	Sun/part shade	Biennial, cold-hardy
Chives	Sun/part shade	Regrows after each cut
Mint	Part shade	Plant it ALONE — it's invasive!
Rosemary	Full sun	Perennial, drought-tolerant
Thyme	Full sun	Perennial, very little water

Basic care, point by point

Light: the key factor

Most herbs want 6 hours of sun (especially basil, rosemary and thyme). A south-facing window or sunny balcony is ideal. Mint and parsley tolerate some shade.

Watering and pots

• Pots with drainage and at least 6-8 inches deep.
• Water when the surface starts to dry; in summer that can be daily. Basil tells you: it "faints" when thirsty.
• Rosemary and thyme prefer to stay drier than wet.

The trick to keep them going: harvest right

Harvesting is pruning, and it makes them bushier:

• Basil: cut above a pair of leaves; never pluck single leaves. Remove flowers as soon as they appear or it turns bitter.
• Chives and parsley: cut from the outside, leaving the center.
• Harvest in the morning, when the aromatic oils peak.

Two herbs deserve their own chapter for how much they take over: mint, which should always live in its own pot because it invades the one next door, and cilantro, which bolts the moment the heat arrives and needs resowing.

Common problems

• Bolting (going to flower): too little harvesting or heat; pinch the flowers.
• Yellow leaves: almost always overwatering. See our yellow leaves guide.
• Aphids or whitefly: wash with insecticidal soap.

Indoors or outdoors

Indoors, place them in the brightest kitchen window. Outdoors they'll grow stronger; bring rosemary and thyme under cover only in hard-frost climates.

Start with basil and parsley and within a few weeks you'll be cooking with your own harvest. A herb looking off? Try the AI diagnosis.
