Description
- Prepare the Soil: Use a premium peat-based soil or a seed-raising mix, ensuring it is free of bark and sticks to avoid fungal issues. Sieve the soil if necessary to remove any large particles.
- Choose the Container: Use a clear microwave-safe takeaway container, like those used for Chinese food. For columnar cacti, opt for a taller container, such as a 750ml one.
- Moisten the Soil: Add a thin layer of soil (about 2-3cm) to the container and tamp it down. Sprinkle just enough water to moisten the soil, avoiding overwatering. Optionally, add a small amount of seaweed solution.
- Plant the Seeds: Evenly distribute the cactus seeds across the surface of the soil. Lightly tamp them down and spray them with a bit more seaweed solution.
- Label the Container: Write the date and species of the seeds on the bottom or side of the container using a permanent marker.
- Cover and Position: Close the container and place it in a bright spot away from direct sunlight. If direct sunlight is a concern, cover the container with shade cloth or a similar material.
- Monitor and Adjust: Check the container daily to ensure the soil remains moist. Adjust watering as needed to prevent the soil from drying out.
- Germination: Within 7-14 days, the seeds should begin to germinate. Some species may germinate faster if using a grow light and heat mat.
- Care After Germination: Keep the container closed for about 6 months or until the seedlings visibly outgrow the container. Resist opening the container to maintain humidity and sterility.
- Acclimatization: After roughly 4 months, begin acclimatizing the seedlings to open air by gradually removing the lid for longer periods each day. Start with 5 minutes and increase the duration over a week or two.
- Repotting: Repot the seedlings into small pots after 6-8 months, ensuring they have enough space to grow without being overcrowded.
By following these steps, you can successfully germinate and grow cactus seeds using the takeaway technique.
