In the kitchen, its leaves release a unique aromatic profile, blending notes of mint and licorice.
They are ideal for naturally sweetening and delicately flavouring infusions, teas, or bringing a touch of originality to your homemade desserts.

- Germination and Sowing of Seeds:

• The ideal period to sow them effectively is in May.
• Sowing earlier is usually unsuccessful because the nights are too cool, causing the seeds to remain dormant.
• Sow the seeds in a pot of fine, pre-moistened potting soil.
• Cover them with only one millimeter of fine soil.
• Water gently and manually using a sprayer.
• Place the pot in a warm location with temperatures between 30 and 35°C.
• Germination generally begins 2 to 3 weeks after sowing.

- Soil Type:

It thrives in almost any type of soil. However, aerated soil rich in organic matter, such as horticultural potting soil or natural compost, is preferred. In pots, it is crucial to drain the bottom well with small stones or clay pebbles.

- Watering:

The "Sugar of the Incas" grows equally well in humid or dry environments. It is important to water it 2 to 3 times a week during summer and once a week in winter. Never let water stagnate in the saucer, as this leads to mold and root rot.

- Light:

Phyla dulcis adapts to various lighting conditions. However, it prefers a full sun location, or partial shade if the plant is still young. For indoor cultivation, it performs best under horticultural neon or LED grow lights.

- Temperatures:

It develops very well when temperatures range from 15 to 35°C; below this range, growth slows significantly. In winter, ensure the plant is kept at a minimum of 10°C.
