Growing Period

Purple basil Dark Opal is ideally sown in the spring, after the last frost, until early summer. It prefers warm temperatures, between 20 and 25°C, for optimal germination.

Planting Distances and Depth

Sow the seeds at a depth of 0.5 cm and space them 2 to 3 cm apart. Once the seedlings are developed, thin them out to leave a space of 20 to 30 cm between each plant. This allows for good air circulation and reduces the risk of diseases.

Germination Time

Beneficial Associations

Purple basil Dark Opal is an excellent companion for tomatoes, peppers, and aubergines. It enhances the flavour of these vegetables and helps repel harmful insects such as aphids and mosquitoes.

Harvest Period

You can start harvesting purple basil Dark Opal about 60 to 70 days after planting. To encourage continuous growth, pinch the stems just above a leaf node. This stimulates the plant to produce new shoots and prevents premature flowering.

Yield

The yield of purple basil Dark Opal depends on the care provided. Each plant can produce multiple harvests of leaves throughout the growing season. A well-maintained garden can provide enough purple basil for regular culinary use.

Product Preservation

To preserve purple basil Dark Opal, you can dry or freeze it. For drying, hang the stems in a dry, well-ventilated place until the leaves are crispy. For freezing, chop the leaves and place them in ice cube trays with a little water or olive oil. Once frozen, transfer the cubes to freezer bags for later use.
