Dream herb seeds are fine, oval, and elongated, measuring an average of 8 millimeters in length. They are generally dispersed by the wind.

How do I properly repot my dream herb plant?

• Prepare a 5-liter pot with light horticultural potting soil rich in organic matter.
• Ensure the bottom of the pot is well-drained with clay pebbles.
• Plant the root section of the dream herb up to the level of the crown.
• Water at the base of the plant immediately after planting.
• Choose a location that is shaded or sunny.
• Depending on the time of purchase, it may be necessary to gently acclimate the plant over several days by placing a plastic bag over the pot.

What type of substrate should I use?

The plant thrives in light, well-draining soil that is relatively rich in organic matter with a slightly acidic pH.
Repot the plant every 4 to 6 months if necessary.

Does my Calea zacatechichi plant need a lot of water?

It must grow in a warm and humid environment, such as a greenhouse or indoors in a bathroom.
It is recommended to water the plant 2 to 3 times a week in summer, and only once a week in winter.
Never let water stagnate in the saucers, as this poses a risk of root rot.

Where is the best place to put my plant?

This rare ethnobotanical plant acclimates to all types of light, whether full sun or shaded spots (under a tree, in front of a window, or in a greenhouse).
For artificial lighting, prefer high-output lamps such as HPS, MH bulbs, agricultural neon lights, or horticultural LED.

Is it hardy? What is the best temperature for growth?

It grows very well when temperatures vary between 15 and 35 °C; below this range, the shrub grows more slowly.
It is a non-hardy plant that cannot withstand freezing temperatures.
Remember to bring the plant indoors before the winter season.

How can I quickly and easily reproduce my dream grass?

The "Leaf of the Gods" can be reproduced by sowing fresh seeds, but also via smothered cuttings (high humidity).
Cut a piece of woody stem and plant it in a mixture of sand and potting soil during the summer period.

Is it susceptible to diseases and pests?

It is not very susceptible to diseases, though some powdery mildew may occasionally appear on the foliage in summer.
Regarding pests, a few whiteflies or spider mites may appear under the leaves.
