How often should I water oregano? ›

Oregano plants like their soil on the dry side and won't be able to adapt to over-watering. As a rule of thumb, this herb needs water every week — but you'll need to monitor the soil to know for sure what your oregano needs.

It has been introduced in parts of eastern and western North America, and can be quite invasive.

Origanum vulgare, commonly known as oregano, is a bushy, rhizomatous, woody-branched perennial which typically grows to 1-3' tall and to 2' wide on square stems clad with aromatic, glandular-spotted, rounded to ovate leaves (to 1 1/2” long) which are usually entire but sometimes have slightly toothed margins.

Oregano only needs about an inch of water per week and is tolerant of moderate drought. Allow the soil to dry out between waterings. Overwatering can cause root rot and other problems.

What is Origanum vulgare good for? ›

Oregano contains chemicals that might help reduce cough. Oregano also might help with digestion and with fighting against some bacteria and viruses. People use oregano for wound healing, parasite infections, and many other conditions, but there is no good scientific evidence to support these uses.

Oregano taken as a tea or used as a salve inhibits bacterial growth and parasitic microorganisms. The herbal tea also helps to alleviate headaches, urinary problems, diarrhea, nausea, lung disorders, vomiting, and jaundice and is used as a mouthwash to help with tooth infections and sore throat.

As plant of Mediterranean origin, oregano needs plenty of full sun with good drainage. It does best in a free-draining compost in porous pots such as terracotta pots. Oregano suffers in wet soil, so if you're planting it in the ground and have heavy soil, make sure you include a handful of grit to the planting hole.

Water newly planted oregano regularly for at least the first summer. This Mediterranean herb is drought tolerant once established and shouldn't need additional watering when growing in the ground. In containers, the compost will dry out rapidly, so water regularly over the summer months.

The soil should be about as moist as a wrung-out sponge. Once the plant has developed a good root system, you can decrease watering. Oregano does not like "wet feet," so always check to make sure that the top inch of soil is dry before watering.

Light and Temperature for Growing Oregano

The ideal soil temperature for planting oregano outdoors is 70 degrees Fahrenheit. Plant oregano in an area of the garden that receives between 6-8 hours of full sunlight, providing partial shade in hotter climates.
