Fresh herbs transform everyday cooking — and they’re among the easiest plants for beginner gardeners. Whether you have a patio, balcony, or sunny windowsill, growing herbs in containers puts flavour at your fingertips without the need for a garden bed.
Quick tip: Containers dry out faster than garden beds in summer and stay wetter in winter — check moisture levels regularly rather than sticking to a rigid schedule.
This guide covers ten reliable herbs that thrive in UK conditions, with specific pot sizes, seasonal guidance, and practical harvest tips. It pairs perfectly with our guide to vegetables to grow in containers — together they cover everything for your patio garden.
What You Need to Get Started
Essential Supplies
- Containers (15–30cm depending on herb — specifics below)
- Multi-purpose compost with horticultural grit for drainage
- Horticultural grit (25% by volume for Mediterranean herbs)
- Watering can with rose
- Plant markers (herbs look similar when young)
Important: Give the living herb pots sold in supermarkets a miss. They’re forced along quickly in commercial greenhouses, which leaves them soft and sappy, so they tend to struggle the moment they go outdoors. For herbs that settle in and last, start them from seed or pick up a healthy plant from a nursery or garden centre.
Container Considerations for Herbs
Drainage is critical. Herbs hate wet feet, especially Mediterranean varieties. Ensure every pot has drainage holes.
Terracotta is ideal. The porous material prevents overwatering — perfect for herbs that prefer drier conditions.
Group by water needs:
- Mediterranean herbs (rosemary, thyme, oregano, sage): prefer drier conditions
- Leafy herbs (basil, parsley, coriander, mint): prefer consistent moisture
Mint warning: Always grow mint in its own pot. Its roots spread aggressively and will quickly overpower other herbs.

Deep Dive — Top Herbs
Basil — The Beginner’s Best Friend
Basil is the quintessential container herb. Fast-growing, fragrant, and endlessly useful — it’s the perfect starting point for new gardeners.
For detailed advice, check our guide to growing basil in a pot.
Best varieties: ‘Sweet Genovese’ (classic Italian), ‘Greek’ (compact, smaller leaves), ‘Thai’ (aniseed notes, spicy)
Growing: Sow every three weeks for continuous supply. Basil germinates quickly indoors on a warm windowsill.
Care: Likes consistent moisture — don’t let it dry out completely. Pinch out growing tips regularly to encourage bushy growth. Remove flower buds immediately — flowering turns leaves bitter.
Harvest: Pick from the top, leaving at least two sets of leaves on the stem. This encourages branching.
Mint — Contain or Regret
Mint is delicious and useful — but it’s a garden thug. Containers aren’t just convenient for mint; they’re essential. See our full guide on how to grow mint in containers for variety choices, potting advice and overwintering tips.
Best varieties: Spearmint (cooking, mint sauce), Peppermint (tea), Chocolate mint (desserts, subtle cocoa notes)
Why dedicated pots matter: Mint roots spread aggressively underground. In open ground, it takes over. In a container, you control it completely.
Care: Mint prefers moist, fertile soil and partial shade — an east-facing spot is ideal. When it looks straggly, lift the root ball, divide it, and repot fresh pieces into rich compost.
Harvest: Cut stems to ground level — it’ll resprout vigorously.
Rosemary — The Permanent Resident
Rosemary is a long-term investment. Given the right conditions, a single plant provides harvests for seven to eight years. For full growing details, see our guide to growing rosemary in pots.
Critical pot size: Rosemary needs a minimum 30cm (1ft) wide and deep pot. Smaller containers lead to poor establishment and winter vulnerability.
Care: Full sun is essential. Drought-tolerant once established — water sparingly. Rosemary hates soggy roots, especially in winter. Use gritty compost with 25% horticultural grit mixed in.
Position: Sunny and sheltered from harsh winds.
Harvest: Snip sprigs as needed year-round. The soft new growth in late spring has the best flavour.
Winter protection: Container rosemary is vulnerable to freezing. If temperatures below -8°C are forecast, wrap the pot in bubble wrap or move to a sheltered spot near a wall. Cold, wet compost kills roots faster than cold air.
Parsley — The Reliable Workhorse
Parsley is biennial — it lives two years, then flowers and dies. For continuous supply, sow fresh each year.
Types: Flat-leaf (better flavour, preferred by cooks), Curly (better garnish, holds shape when chopped)
Sowing: Parsley is slow to germinate — three to four weeks. If impatient, buy young plants from garden centres.
Care: Likes consistent moisture and tolerates partial shade better than most herbs. Add garden compost or slow-release fertiliser to the potting mix — parsley prefers richer conditions than Mediterranean herbs.
Harvest: Pick outer leaves first, leaving the centre to continue producing. One plant keeps going for months.
Thyme and Oregano — The Mediterranean Pair
These two share identical preferences: sun, drainage, and minimal fuss.
Care: Both demand full sun and excellent drainage. Add plenty of grit to compost — up to 25% by volume. They’re drought-tolerant and forgiving if you forget to water occasionally.
Harvest: Best flavour is just before flowering. Regular harvesting keeps plants compact and bushy.
Perennial bonus: Both survive UK winters in containers. Established plants tolerate temperatures down to -8°C. Container plants benefit from grouping pots together or wrapping in bubble wrap during extreme cold.
Coriander — The Fast-Bolter
Coriander is delicious but temperamental. Heat and long days trigger it to flower and set seed quickly.
Care: Prefers partial shade in midsummer — afternoon shade prevents premature bolting. Sow successionally every three weeks for continuous leaves.
Dual-purpose: If it does bolt, the seeds are useful too — green seeds have a fresh citrus flavour; dried seeds are the spice.
Harvest: Pick leaves young for best flavour. Once flowering begins, leaves turn feathery and less tasty.
Herb-Vegetable Companion Pairings
Herbs and vegetables grown together benefit each other. Here are proven combinations:
| Herb | Pairs With | Benefit | Container Arrangement |
|---|---|---|---|
| Basil | Tomatoes | Improves flavour, repels whiteflies and aphids | Same large pot (tomato centre, basil at base) or nearby containers |
| Chives | Tomatoes | Repels aphids, antifungal properties | Nearby pots or around base |
| Rosemary | Beans | General pest deterrence | Nearby pots |
| Mint | Brassicas (cabbage family) | Deters cabbage white butterfly | Dedicated separate pot — never plant together |
| Dill | Courgettes | Attracts beneficial insects | Nearby pots |
Space-saving tip: If you’re short on space, basil and tomatoes make the best container-sharing pair. Use a pot at least 30cm diameter for both.
Season-by-Season Herb Calendar
| Season | Key Tasks |
|---|---|
| Spring (Mar–May) | Sow tender herbs indoors: basil, coriander, dill. Plant hardy herb plants. Divide and repot mint. |
| Early Summer (Jun) | Harden off tender seedlings. Plant out after last frost. Start harvesting first basil. Begin feeding container herbs every 2–3 weeks. |
| Mid Summer (Jul–Aug) | Peak harvest season. Succession sow coriander. Take cuttings from thyme and rosemary. Provide afternoon shade for coriander. |
| Autumn (Sep–Oct) | Harvest and dry herbs for winter. Pot up divisions of mint and chives. Move tender herbs indoors or to sheltered spots. |
| Winter | Minimal watering. Protect Mediterranean herbs from waterlogging. Basil needs warm windowsill indoors. Plan next year’s herbs. |
Harvesting and Preserving
Fresh Harvest Tips
- Morning harvesting = best flavour (essential oils at peak)
- Cut, don’t pull — clean cuts heal faster
- Regular harvesting encourages bushier growth — even if you don’t need herbs, trim to maintain shape
Preserving Methods
Drying:
- Hang small bunches upside down in warm, dark, well-ventilated place
- When crisp, strip leaves and store in airtight jars
- Best for: rosemary, thyme, oregano, sage
Freezing:
- Chop leaves and freeze in ice cube trays with water or olive oil
- Best for: basil, parsley, coriander, chives
Herb Butters:
- Mix finely chopped herbs with softened butter
- Roll into log, wrap, freeze
- Slice as needed
Common Herb Growing Mistakes
Mistake #1: Overwatering Mediterranean Herbs
Rosemary, thyme, oregano, and sage come from hot, dry climates. They want “dry feet.”
Solution: Add 25% horticultural grit to compost, use terracotta pots, water only when soil is dry.
Mistake #2: Letting Basil Flower
Once basil flowers, leaves turn bitter and production slows.
Solution: Pinch out flower buds as soon as they appear. Sow successionally for continuous supply.
Mistake #3: Planting Mint With Other Herbs
Mint roots spread underground and takeover.
Solution: Always grow mint in its own dedicated pot. Never plant in open ground unless you want a mint lawn.
Mistake #4: Pots Too Small for Rosemary
Rosemary in a small pot becomes stressed, produces poorly, and dies in winter.
Solution: Minimum 30cm diameter and depth. This is non-negotiable for success.
Mistake #5: Wrong Sun Exposure
- Basil in shade = leggy, weak, prone to disease
- Mint in full sun = scorched, crispy leaves
Solution: Match herb to position. Mediterranean herbs need 6+ hours sun. Leafy herbs tolerate partial shade.
Troubleshooting
| Problem | Likely Cause | Solution |
|---|---|---|
| Yellow leaves | Overwatering | Reduce watering, check drainage holes aren’t blocked |
| Leggy, weak growth | Insufficient light | Move to sunnier spot; south-facing for Mediterranean herbs |
| Basil turns black | Cold damage | Basil is tender below 10°C; bring indoors |
| Coriander flowers quickly | Heat/light stress | Provide afternoon shade; succession sow every 3 weeks |
| Woody, bare stems (thyme/rosemary) | Lack of pruning | Prune after flowering to encourage new growth |
| White fuzzy mould | Poor air circulation | Space pots apart; reduce watering; remove affected leaves |
| Mint looks straggly | Needs repotting | Lift, divide roots, repot fresh pieces into rich compost |
Quick-Reference Tables
Minimum Pot Sizes by Herb Type
| Herb Type | Minimum Pot | Compost Notes |
|---|---|---|
| Annual herbs (basil, coriander, dill) | 15cm (2–3L) | Standard multi-purpose |
| Perennial herbs (thyme, chives, oregano) | 15–20cm (3–5L) | Add grit for Mediterranean types |
| Woody herbs (rosemary, sage) | 30cm+ (12L+) | Gritty mix essential; John Innes No 3 for long-term |
| Invasive herbs (mint) | 25cm (5L+) | Rich, moist compost; dedicated pot essential |
Sun vs Shade Herbs
| Sun Level | Hours/Day | Herbs |
|---|---|---|
| Full sun | 6+ hours | Basil, rosemary, thyme, oregano, sage, chives, dill |
| Partial sun | 3–5 hours | Parsley, mint, coriander |
Water Requirements
| Water Needs | Herbs | Care |
|---|---|---|
| Low (drought-tolerant) | Rosemary, thyme, oregano, sage | Water when soil dry; terracotta ideal |
| Medium (consistent moisture) | Basil, parsley, chives, coriander | Don’t let dry out completely |
| High (moist soil) | Mint | Keep consistently damp; repot frequently |

Frequently Asked Questions
Q: What’s the easiest herb to grow in a pot?
A: Chives. Practically indestructible, tolerate shade or sun, and come back every year with zero fuss.
Q: Can I grow herbs indoors on a windowsill?
A: Absolutely. Basil, parsley, and chives do well indoors. South-facing windows are best. Supplement with grow lights in winter if needed. Windowsill herb kits make starting easy.
Q: How often should I water container herbs?
A: Mediterranean herbs (rosemary, thyme, oregano, sage) — when soil is dry to touch. Leafy herbs (basil, parsley, coriander, mint) — keep evenly moist. Check by pushing finger 2cm into compost.
Q: Can I plant different herbs in the same pot?
A: Yes, but group by water needs. Basil + parsley work together (both like moisture). Rosemary + thyme + oregano work together (all Mediterranean, dry-loving). Never plant mint with anything.
Q: Why does my coriander keep bolting?
A: Heat and long daylight hours trigger flowering. Sow successionally every three weeks, provide afternoon shade in summer, and harvest leaves young.
Q: Should I feed container herbs?
A: Lightly. Herbs prefer poorer soil than vegetables. A weak liquid feed every 2–3 weeks during growing season is plenty. Avoid high-potash feeds — they promote flowering over leaf growth.
Q: How do I overwinter container herbs?
A: Mediterranean herbs — move to sheltered spot, reduce watering, wrap pots if very cold forecast. Tender herbs (basil) — bring indoors to sunny windowsill or treat as annual and resow in spring.
Q: Why did my supermarket herb die when I put it outside?
A: Those pots are raised in warm, sheltered nursery conditions, so the growth is soft and hasn’t toughened up — dropped straight outside, it rarely copes. For anything you’ll keep in an outdoor container, sow your own or buy a garden-centre plant that’s been grown harder.
