Factors to Consider About How to Grow Oregano
Weather for Oregano
Oregano is a plant capable of growing best in moderately warm climates, however, the cultivation of oregano can withstand temperatures ranging from 39.2°F to 89.6°F (4 ° C to 32 ° C)., being ideal a temperature ranging between 69.8°F to 77°F (21 ° to 25 ° C).
Luminosity for Oregano
Oregano requires a lot of light and needs to receive direct sunlight for at least a few hours a day. If you want a spicier oregano crop with a stronger aroma you should expose the plant for a longer time to sunlight.
Soil for Oregano
One point to keep in mind about how to plant oregano is that the soil should be well-drained and preferably fertile, despite what was said above, this plant can grow even in poor soils. The plant is quite tolerant to the pH of the soil, the ideal being a pH between 6 and 8. Another point to keep in mind about how to grow oregano is that the soil must be calcareous.
A tip on how to grow oregano is that this plant should be watered frequently to keep the soil moist. Once the crop is well developed, the soil can be allowed to dry out for a short period. Nor should the oregano crop be allowed to become waterlogged, since both the lack and excess of water can damage this plant.
How to Plant Oregano
Oregano can be grown either by seed, by the division of rhizomes (consists of cutting the subway rhizomes, so that new plants grow) or by cuttings (consists of planting small cuttings taken from the stems, roots, or leaves that are planted in a humid environment, so that new plants grow), the latter two being the preferred methods in terms of how to plant oregano since planting by seed requires more time for the growth of plants and their harvest.
The seeds can be sown directly in the place where they will grow, they can also be sown in seedbeds, small pots or cups made of newspaper with a measure of 4” (10 cm) in height and 2” (5 cm) in diameter. In the latter cases, the plants should be repotted from the seedbed when they have four pairs of definitive leaves. Germination usually occurs within two weeks.
In places where winter is not too severe, the plant can be grown as a perennial, forming clumps with tangled roots. You can divide this plant every 2 to 3 years and use them to increase the number of oregano crops. The disadvantage of this method is that the old plants produce leaves without much flavor in contrast to the leaves taken from the young plants.
Cultivation by cuttings taken from the branches of healthy plants is the ideal method, as it produces plants very similar to the parent plant and these take less time to grow. The branches should be cut approximately 6” (15 cm) long and the leaves should be removed, leaving only those at the nearest end of the branch (3 or 4 pairs of leaves). Finally, the lower part of the branch should be submerged in a container with water until the roots grow, and then it should be planted in the chosen place.
The separation between oregano cultivations can be 12” (30 cm), however, this value can vary according to the size of the oregano cultivation.
This plant can also be grown in pots and containers of medium or large size, being the care of oregano in pots the same.
Another point to keep in mind about how to plant oregano is that we must remove all traces of invasive plants as they absorb nutrients and resources.
