We are again trying to grow sequoias from seed, but this time we are trying to correct our mistakes. We used regular tap water last time to cold stratify the seeds - but this may have lead to "damping off" or fungal disease. This time we committed to distilled water. We tried to grow the sequoias inside, during the winter, under artificial light. This time we will plant and keep the trees outside even during winter (but in a cold frame if necessary).
So, to start off, we acquired 2000 more sequoia seeds from Myseeds.co, our preferred site. We expect again about a 10% germination rate, so perhaps around 200 trees. We plan to distribute these trees across the country for growth with the Waterboxx in a few years.
First, assemble all needed materials. To stratify (prepare seeds for germination), you will need to following materials:
- A clean paper plate
- Two clean paper towel squares
- A clean sealable kitchen bag
- Sequoia seeds (at least 10 seeds for every desired tree)
- Distilled water (which won't have any fungal spores which can kill young saplings)
|What is needed to cold stratify the seeds - paper plate, two paper towels, sealing kitchen bag, seeds, and distilled water|
First, wet one of the paper towels with the distilled water. Lie this paper towel flat on the paper plate. Then, carefully spread the (small) sequoia seeds on the wet paper towel, as evenly as possible.
|Spread the sequoia seeds on the paper towel wetted with the distilled water - do this with clean hands only|
Next, take the second paper towel and wet it with the distilled water. Lay this carefully over the paper plate now covered with sequoia seeds. If some seeds get pushed off the plate, I would pick them up and put on the plate - remember that each seed may grow into a tree that will store a lifetime of carbon emissions and live for millenia.

Groasis Waterboxx during our annual spring sequoia donation and planting, or distribute the trees to our customers.
We will update this post with our progress and next steps in early May.
