Appearance and characteristics of tulsi

Tulsi has hairy green and purple to red leaves with deep veins and a strong scent. Tiny white to purplish flowers are produced on tall spikes in summer. Both the leaves and the flowers are edible.

Uses for tulsi plants

Tulsi is a fabulous culinary herb and is said to settle the stomach and clear the mind. It is often used in Thai cuisine, where it is prized for its spicy, pungent flavour. It’s also used in Ayurveda as a treatment for many different ailments.

Once your plant is over 30cm tall, you can harvest the leaves with a pair of scissors and use them fresh or dried. Tulsi is widely used as an essential oil, a herbal tea or as an alternative to coffee. The dried leaves can even be used as an insect repellent.

How and when to plant tulsi

  • Tulsi loves rich soil full of organic matter and mulch to keep the moisture in. 
  • In frost-free areas, tulsi can be grown outside all year round. 
  • Choose a spot in full sun, although in very hot areas some afternoon shade would be beneficial.
  • If you live in a cooler area, you can grow it as an indoor plant by a sunny window. 

How often should you water and feed tulsi plants?

Give your tulsi a regular watering once a week during summer. Try not to get water on the foliage as this can cause fungal disease and leaf spot. Don’t let the soil or potting mix dry out. For strong growth and great tasting tulsi, a regular feed with a liquid seaweed extract will keep your plants strong and healthy.

Diseases and pests of tulsi plants

Snails and slugs are the main pests to look out for. Leaf spots and mildew can be a problem and are best treated with an organic fungicide. Always follow the instructions on the label carefully. If the soil is moist, but your plant is wilting, it may be infected with fusarium wilt. Destroy infected plants to avoid this fatal disease from spreading.

Pruning tulsi plants

Constant tip-pruning throughout the year helps to promote bushier and more compact growth. Just make sure you only remove the tips, as pruning too far down the stem could kill the plant.

How to propagate tulsi plants

Tulsi is a tricky plant to grow from seed so cuttings are the best bet. 

How to grow tulsi from cuttings

  1. Take a cutting from the tip of a plant, making sure you’ve removed any flowers and some of the leaves. 
  2. Put it in a jar of water on a warm windowsill. 
  3. Once the roots begin to form, put it in a pot in some moist potting mix.

Safety tip

After applying fertiliser, delay harvesting for a few days and rinse well before eating. If using products to deal with pests, diseases or weeds, always read the label, follow the instructions carefully and wear suitable protective equipment. Store all garden chemicals out of the reach of children and pets.
