Growing Oregano


July 25, 2022

A prevalent Mediterranean herb used in kitchens, Oregano can claim many accolades for garden suitability, hardiness and multiple health benefits. Oregano is a perennial herb initially used for its antiseptic, antifungal and medicinal properties.

Nowadays its spreading habit makes it desirable to gardeners for rockeries, cottage gardens, companion vegetable gardens and potted patio gardens. With its robust, earthy and aromatic flavour, Oregano is a grab-and-go herb that complements many dishes in the kitchen.

A Mediterranean climate and areas where the summer is hot and dry are ideal for growing Oregano, but it will grow happily in every climatic zone in Australia. For cold regions, ensure the plant is well established by Winter and mulched moderately to protect roots and stems from the elements.

If you're looking to grow your very own Oregano, start by choosing a sunny spot in the garden with free-draining soil. Good drainage and air circulation are especially important if growing Oregano in humid weather. Before planting enrich the soil with plenty of compost and manure to aid good drainage. Enrich the soil with compost dig 5 IN 1 Organic Fertiliser into the soil before planting. For potted Searles Herb & Vegetable Specialty Mix is ideally designed for aiding water retention and nutrients for their growth.

Watering Oregano

Oregano roots grow shallowly, so water regularly and mulch to keep the moisture in. Water more frequently if planted in pots, as potting mixes dry our quicker.  

Companion planting with Oregano

Oregano’s antiseptic and antifungal properties make it a great companion planted alongside beans, cabbage, cauliflower, capsicum, sprouts, strawberries and especially tomatoes.

Fertilising Oregano

Oregano grows happily unassisted for many months if the soil is rich in compost and manure before planting. Liquid feeding every month with SeaMax Organic Fertiliser will keep the nutrients in the soil topped up and strengthen the plants' defence against the cold.

Harvesting Oregano

Cut sprigs often to encourage more growth, keep compact and to delay flowering.

Oregano (Origanum vulgare) is often referred to as wild marjoram. Still, it is important to note, Oregano and marjoram (Origanum majorana) are closely related to the same mint family but differ in their leaf size and particularly smell and taste. Oregano is more pungent and savoury in flavour with larger leaves, while marjoram has a much milder, sweeter flavour.
