Do you have to freeze the seeds before you plant them? What kind of soil do they need? How much watering do they need? How long until they sprout? What then?

Thanks for answering

Sequoia seeds do best soaked overnight in distilled water then chilled for more than 60 days in damp sand at ~37 F. They do not need to be frozen just chilled in the fridge in a sandwich bag. About 40%-90% (depending on age and condition of seed) will sprout by 5 weeks but some will be sooner.
Two germination methods
The baggie method is to keep them in their stratification baggie with a suitably moist germinating mix. Vermiculite works fine, sand or even between damp paper towels. Only one damp towel on top though because they need light to germinate. The baggie is then stored under grow lights at moderate room temperature. You should not let the bag get warm or they may rot. Do not use an incandescent lamp only fluorescent or grow lights that do not heat the seeds. When the seeds begin to germinate, you remove the small plants, known as germinants, and plant them in a suitable container.


Sprinkle them on soilless potting media for seed starts. Then lightly sprinkle a layer of the soilless media over the seeds. Make sure that you don't cover them too deeply they only need about 1/3 of their width, which means it is best to just "barely" cover them up. Set up lights. Even fluorescent lights will work for germination. Place a clear plastic cover over the media or mist very frequently to keep them just moist.

Redwoods can be fed with a fertilizer for acid loving plants, they like a pH that is on the acid end from 4.5 to 6.5 in sandy loam. Apply fertilizer Valentines, Labor, & Christmas days or spring, fall & winter when water is available in the soil once they are planted out in full sun.

N-P-K ratios should be 3-1-2 or 3-1-1 or a multiple of those like 6-2-4 at most. These are not fast growing trees.
