10 Best Herbs to Grow Indoors on a Sunny Windowsill

A pot of fresh herbs on the kitchen windowsill is one of the most rewarding things you can grow — useful every day, fragrant, attractive, and far cheaper and fresher than supermarket packets that wilt in days. An indoor herb garden is genuinely achievable, but it has one hard requirement most beginners underestimate: light.

Here are the 10 best herbs for indoor growing, honestly rated, plus how to keep them thriving.

The One Thing That Decides Success: Light

Most herbs are sun-lovers — they evolved in bright, open Mediterranean climates. Indoors, they need the brightest spot you have: ideally a south- or west-facing windowsill with 6+ hours of direct sun.

In a darker home, or through dark winters, herbs grow leggy, pale, and weak. The honest fix is a grow light — a small LED grow light turns any kitchen counter into a viable herb garden and is the difference between thriving herbs and a sad, stretched pot. If you have no bright window, plan for a grow light from the start.

The Easiest Indoor Herbs

Chives

Chives are the most forgiving herb to grow indoors — they tolerate a little less light than most, grow back quickly after cutting, and are hard to kill. Snip them with scissors as needed.

Mint

Mint is vigorous and easy — almost too easy. Indoors that’s an advantage: it grows happily, tolerates part sun, and gives endless leaves for tea and drinks. Always grow mint in its own pot — it’s an aggressive spreader that will swamp anything sharing its container.

Parsley

Parsley is reliable, tolerates a range of light, and crops for a long time. It’s slow to germinate from seed, so buying a young plant is the easy route.

Thyme & Oregano

Both are tough, drought-tolerant Mediterranean herbs that thrive on a bright windowsill and dislike being overwatered — let them dry between drinks. Compact and long-lasting.

The Herbs That Need More Care

Basil

Basil is the herb everyone wants and the one most often killed. It demands lots of light and warmth — a cool, dim windowsill makes it sulk and collapse. It also hates wet feet. Give it your brightest, warmest spot, water when the topsoil dries, and pinch out the growing tips regularly to keep it bushy and stop it flowering (once basil flowers, leaf production fades).

Rosemary & Sage

Both are woody Mediterranean herbs that want bright light and excellent drainage, and resent overwatering. Indoors they appreciate good airflow. Rosemary in particular sulks in dim, stuffy rooms — give it the sunniest spot.

Cilantro / Coriander

Cilantro is fast but short-lived — it “bolts” (runs to flower) quickly, especially in heat. Sow a little, often, for a continuous supply, and keep it somewhere a touch cooler.

Lemongrass

Easy and dramatic — lemongrass grows into a tall, grassy clump and even roots from a supermarket stalk stood in water. It wants warmth and bright light.

How to Keep Indoor Herbs Alive

1. Maximise light. The brightest windowsill, or a grow light. This is non-negotiable — it’s the #1 reason indoor herbs fail.
2. Use pots with drainage holes. Herbs, especially Mediterranean ones, hate soggy roots.
3. Don’t overwater. Let the topsoil dry between waterings for thyme, rosemary, oregano, and sage. Basil, parsley, mint, and chives like a little more consistent moisture — but never sogginess.
4. Give them room. Supermarket herb pots are usually many seedlings crammed together — they exhaust themselves fast. Re-pot into a larger container with fresh soil, or split the clump, so plants have space.
5. One herb per pot, mostly. Herbs with different water needs (thirsty basil vs dry-loving rosemary) don’t share a pot well. Keep mint isolated always.
6. Harvest correctly — and often. Pinch from the top and snip regularly. Cutting encourages bushier growth; an unharvested herb grows leggy. Never strip more than about a third of the plant at once.
7. Pinch out flowers. For leafy herbs (basil, especially), removing flower buds keeps the plant producing tasty leaves for longer.
8. Feed lightly. A weak liquid feed every few weeks in the growing season keeps them productive — but go gently; over-fed herbs lose flavour.
9. Rotate the pots so herbs leaning toward the light grow evenly.

A Realistic Indoor Herb Garden

For a reliable, useful kitchen herb garden:

• Start with the easy herbs — chives, mint (own pot), parsley, thyme.
• Add basil only if you have a genuinely bright, warm spot or a grow light.
• Buy young plants rather than starting everything from seed — faster and more reliable.
• Re-pot supermarket herbs into bigger containers immediately.
• Harvest little and often, from the top.

Frequently Asked Questions

What is the easiest herb to grow indoors?

Chives and mint are the easiest — both tolerate slightly less light than other herbs, grow back quickly after cutting, and are hard to kill. (Keep mint in its own pot.)

Why does my indoor basil keep dying?

Basil needs lots of light and warmth and hates wet feet. A dim, cool windowsill and overwatering are the usual killers. Give it your brightest, warmest spot, let the topsoil dry between waterings, and pinch out the tips and flowers.

Do indoor herbs need a grow light?

If you have a bright, sunny windowsill, no. In a darker home or through dark winters, yes — a grow light is the honest fix and the difference between thriving herbs and leggy, failing ones.

How do I keep supermarket herbs alive?

Supermarket pots cram many seedlings together, exhausting them fast. Re-pot into a larger container with fresh soil (or split the clump), give them strong light, water properly, and harvest little and often.

How should I harvest indoor herbs?

Pinch or snip from the top of the plant, regularly, never taking more than about a third at once. Frequent cutting encourages bushier growth; leaving herbs unharvested makes them leggy.
