How To Grow Herbs

Project Overview

Herbs are a great addition to your garden as they require little space and attention, and food always tastes so much better coming from your own garden.

Culinary herbs:
Culinary herbs are herbaceous (leafy) plants which add flavour and colour to your meals when you add their seeds, flowers, leaves or roots. Like most herbs, culinary herbs are tolerant of a wide range of growing conditions and grow well with very little maintenance. If you plan your drainage, prepare the soil, plant and water correctly then you'll have fresh herbs to enjoy in the kitchen all year round.

Types of culinary herbs: Basil, Fennel, Oregano, Bay, Garlic, Parsley, Chilli, Ginger, Rosemary, Chives, Lemongrass, Sage, Coriander, Marjoram,Tarragon, Dill, Mint, Thyme.


Always keep tools and materials away from children.

3 Planting
4 Harvesting
  • Step 1. Drainage

    When selecting a site for a herb garden you must consider drainage as wet soils aren't suitable for the majority of herbs. If the only area available has poor drainage then you'll need to modify the area by building raisedbeds, install underground agi pipe or simply plant your herbs in large pots, planter boxes and troughs.
  • Step 2. Prepare the soil

    Once you are certain the drainage is suitable, it is time to prepare the soil. Soil preparation for culinary herbs is similar for vegetables in that they prefer a light, well-drained, crumbly soil, but most herbs will grow satisfactorily in fairly heavy soil provided there is good drainage. Dig the soil to a depth of about 25 cm (Fig 2), remove all weeds and break up clods to bring the soil to a moderately fine texture. If the soil lacks humus, place 5-10 cm of organic matter, such as straw or compost, on the surface and dig in to spade depth. At the same time, apply animal manure, blood and bone, or a complete fertiliser.

  • Step 3. Planting

    When planting check herb labels for height and widths so you can space and position appropriately. Taller growing herbs should be placed at the rear of the area so as not to shade out smaller herbs as they grow. It is important that your herbs receive at least 6 hours of sunlight a day and that they have adequate space for growth. You may also like to plant your herbs throughout your garden amongst other plants if space is an issue. A regular application of liquid or soluble fertiliser will accelerate growth and increase the yield.

  • Step 4. Harvesting

    Many herbs are prolific growers and harvesting helps to keep them under control, but don't be afraid to cut them back ruthlessly. Picking or pruning the fresh looking tips is the best way to stimulate new growth - chives and mint are a great example. Leafy plants like Oregano, Basil, Thyme, Sage all benefit from constant tip pruning or picking.
