Herbs are one of the most rewarding things to grow on an allotment. They’re productive, low-maintenance, great for beginners, and many will thrive even when vegetables struggle. Whether you grow them in beds, containers, or tucked between crops, herbs give reliable harvests from early spring to late autumn — and some year-round.

This guide explains which herbs to grow, where to grow them, how to care for them, and how to avoid common mistakes.

🌱 1. Why Grow Herbs on an Allotment?

Herbs are ideal because they:

• need little space

• tolerate irregular watering

• deter some pests

• can be harvested repeatedly

• are expensive to buy fresh

Many herbs also attract pollinators, supporting the wider allotment ecosystem.

🌿 2. Annual vs Perennial Herbs (This Matters)

Understanding this avoids frustration later.

🌼 Annual Herbs (One Season)

These grow, flower, and die in one year.

• Basil

• Coriander

• Dill

• Chervil

➡ Best sown little and often for continuous harvests.

🌳 Perennial Herbs (Come Back Every Year)

These live for several years.

• Rosemary

• Thyme

• Sage

• Mint

• Chives

• Oregano

➡ Give them permanent space — they don’t like being moved.

🗺️ 3. Where to Grow Herbs

In Beds

Best for:

• thyme

• sage

• oregano

• chives

Tips

• Choose free-draining soil

• Avoid rich, overfed beds (too much leaf, less flavour)

In Containers (Highly Recommended)

Perfect for:

• mint (essential — it spreads)

• basil

• parsley

• tender herbs

Benefits

• Easy watering control

• Portable in bad weather

• Prevents invasive spread

Mixed Into Vegetable Beds

Many herbs grow well alongside crops:

• chives near carrots

• basil near tomatoes

• thyme near brassicas

This saves space and encourages beneficial insects.

🌞 4. Light, Soil & Water Requirements

Sun

Most herbs need:

• 6–8 hours of sunlight per day

Exceptions:

• parsley

• mint
  (these tolerate partial shade)

Soil

Herbs prefer:

• free-draining soil

• moderate fertility

Too much nitrogen = lots of leaves, less flavour.

Watering

• Water regularly while establishing

• Once established, many herbs prefer drier soil

• Containers dry faster — check more often

✂️ 5. Harvesting Herbs Properly (For Bigger Yields)

Harvesting correctly encourages more growth, not less.

General rules

• Never remove more than ⅓ of the plant at once

• Cut just above a leaf joint

• Harvest little and often

Best time to harvest

• Morning, after dew dries

• Before flowering for best flavour

❄️ 6. Overwintering & Long-Term Care

Hardy perennial herbs

Rosemary, thyme, sage:

• Survive winter outdoors

• Benefit from light pruning after flowering

• Avoid waterlogged soil

Tender herbs

Basil, coriander:

• Killed by frost

• Grow annually or move to a greenhouse/windowsill

Mint (Special Case)

• Extremely hardy

• Spreads aggressively

• Always grow in containers

🐛 7. Common Herb Problems (and Simple Fixes)

• Yellow leaves → overwatering or poor drainage

• Weak flavour → soil too rich or shade

• Leggy growth → not harvested enough

• Aphids → squash, water spray, or leave (often self-resolve)

Herbs generally suffer fewer pests than vegetables.

🧠 Key Principles for Herb Growing

• Poorer soil = stronger flavour

• Containers solve most problems

• Harvesting improves growth

• Perennials need permanent space
