Coriander Growing Guide

Coriander Growing Guide

Coriander is a quick-growing and very hardy annual herb that can be grown year-round. In fact, it seems to flourish more in the cooler months, when it’s less likely to bolt and go to seed. Widely used in Asian cooking, coriander leaves have a delicate sweet flavour and are used cooked in dishes and fresh, including as a garnish. All parts of the plant are edible, from the roots to the stems, leaves and seeds.

Prepare

Coriander will happily grow in almost any well-dug soil in both sun and a little shade (one of the few crops that will). Note, however, that it has a delicate root system and doesn’t like to be disturbed, so be careful it you have to move young plants about. 

Refer to our Planting Calendar.

Plant

Like building a house a good foundation is the key to success in your garden. The better the soil, the better your plants will grow. If you are starting with an existing garden bed dig in organic matter like Tui Sheep Pellets and Tui Compost to your soil. Then you can add a layer of Tui Herb Mix. If planting in pots and containers, fill with Tui Herb Mix.

The best times to plant are early in the morning or late in the day, so the plants aren’t exposed to the hot sun straight away. Always water plants well before and after planting.

Don’t be shy when planting herbs as they quite like close neighbours, and you can always plant herbs in between other plants as they make great space fillers and companion plants.

Planting in garden beds:

  • Dig a hole, approximately twice the size of the root ball of your plant.
  • Partly fill hole with Tui Herb Mix.
  • Fill a bucket with water and add two capfuls of Tui Organic Seaweed Plant Tonic, a seaweed based plant tonic that promotes strong root growth and reduces transplant shock.
  • Soak seedlings in the bucket of Tui Organic Seaweed Plant Tonic, ensuring they are fully submerged.
  • Gently loosen the root ball of your plant and position the plant in the centre of the planting hole.
  • Fill in with Tui Herb Mix.
  • Press soil gently around the base of the plant.
  • Water well.

Planting in pots and containers:

  • If your container has no drainage holes, add stones to the bottom of the container to act as drainage.
  • Partly fill your container with Tui Herb Mix. Tap the container gently on the ground to settle the mix.
  • Fill a bucket with water and add two capfuls of Tui Organic Seaweed Plant Tonic. Soak seedlings in the bucket ofTui Organic Seaweed Plant Tonic, ensuring they are fully submerged.
  • Gently loosen the root ball of your plant and position the plant in the container. Ensure the plant is sitting at the same level in the soil as it was in its seedling container.
  • Fill in with Tui Herb Mix, up to 3cm from the top.
  • Press soil gently around the base of the plant.
  • Water your plant well.

Nourish

Feed your herb and they will feed you. Plants use nutrients from the soil as they grow, so replenishing the nutrients ensures your plants grow to their full potential.

Feed your herbs with Tui NovaTec Premium fertiliser. Well-watered, well-nourished herbs will have a better chance of keeping insect pests and diseases at bay.

Over summer coriander is prone to go to seed. To avoid, water your coriander consistently, regularly pick, remove flowers and remove parts of the plant that go to seed. If your coriander does go to seed there is an upside – the flowers are great for beneficial insects like bees, and if you let them fully dry out you can collect the seeds for next season!
