Having only once before attempted to grow this rather temperamental species I thought that as I am selling this seed I need to know how well it performs in real growing conditions rather than quoting laboratory germination result statistics.
The seeds were placed in a ziplock freezer bag, the bag was then filled with enough ordinary cold tap water (with no sterilisation) to immerse the seeds. The bag was then sat on a shelf at room temperature for approximatly 24 hours. I then hung the bag up in an outbuilding using a bulldog clip and pierced several times at the base to allow the water to escape. I then gently squeezed out the remaining water with my hand and placed the bag in the fridge. This process is known as naked prechilling.
Expecting a delay of at least 4 weeks until any signs of root emergence I was greatly surprised to see lots of seeds with small white roots after only 15 days. I removed the germinating seeds individually with tweezers and placed them 1 seeds per cell into plug trays. The remaining unsprouted seed was returned to the fridge. I check the bag every 4/5 days, I have found that new seeds are continually germinating which I remove from the bag for planting in cell trays.
I'll just let the seeds in the plug trays develop for a few more days and I'll upload a photo.

very nice :)
Hi, so I don't just chill them for 4 weeks then partially sow them?
It's really nice. As I've heard some people said that the germination rate is pretty low for redwood. You did a great job!! Did you use fresh seeds? Thanks much. ;)
The germination rate is lower than for many other conifer species. The seed lot than I am growing and selling is lab tested at 22% germination which is within the normal range. The seed was collected in 2010 and can be successfully stored for many years under the correct conditions. Best wishes, Michael
I just took my coast and dawn redwood seeds out of refrigerator after stratifying them for 4 weeks and sew them in sterile soil. I put the seed sowing container in dark place around 77 - 89 degrees. Hopefully they will germinate. Keep my fingers crossed.
Vermiculite is best to get seeds to germinate, then once this has happened pot them up using seed compost as its nice and fine.
Hi Mark, drop me a line via the Redwood Trees group on Facebook. im very interested in what you are doing, and would love to help out in other areas! Carl
I have a redwood forest of over 80 trees at my vineyard in Tasmania.
hi Mark i just started a small nursery here in Indonesia on redwood sempervirens and have manage to plant 11 on my premise. its almost 2 years old now and i would like to start using them as mother trees for vegetative propagation do you think its a better idea then starting from seeds. rgds
Do you still grow them ? I’d be interested in working with you
I've been worried about germinating conifers on the same container. In my experience, i've always failed to get ever the most tiny pine seedling from the forrest flor.
I would be willing to exchange Sequoia semperviren seed for your Pinus and Cypress seed. I would also be able to include Sequoiadendrum giganteum and Metasequoia. My email is email@example.com if you would like to contact me.
Send me your address and I'll ship some to you freshly harvested from the coast of California where I live. Hope this gets to you even though you posted 4 years ago?
Hey Alan, I noticed you have one of the most recent responses and are likely to see this. I am currently trying to get into Bonsai and I want to create a multi tree Bonsai display to recreate some pictures of Hyperion. Unfortunately living in USDA 3b, this is the only viable way for me to grow these amazing trees since my climate cant support them naturally. But I'll be damned if I can't at least do my part to grow them in some form or another haha.

I want to gather my own seeds and attempt to germinate them. I have access to three trees that are about 80 to 100 years old. I believe they are coastal sequoia. The question I have not found the answer to is how do I know when a pine cone has mature seeds in it that have a chance of being germinated. I know you have male and female parts on the same tree but during what time of the year should you pick the pine cones to harvest their seeds?
I would try picking the closeed mature cones and the closed green cones that look full. I've had succes with cupressus in that way. After drying (some heating up may help) they open apart easily.
Hello, Viability is usually the oldest trees. At 80 to 100 years, those trees are still considered young, and not mature, although there have been reports of viability being at an age of 24 years. There is even proof that a tree just one year old produced a cone. Of course this cones seeds are not viable. If your tree is 80-100 years old. Consider viability only at 5-10% compared to 25-40% for very mature trees. If you want viable seeds, i have a couple hundred thousand coastal redwood seeds! :-) firstname.lastname@example.org
I'm in WNY, and have a huge tract of land that hopefully I can get a grove going. I have a few thousand seed of Sequoia/Coastal/Dawn. My property is 99% sandy loam soil, and has a grade to it (drainage). I will be using Groasis Waterboxx(water column), and Mycorrhizae soil mix (root development). Jiffy 50 mm Forestry Pellets seem the best or Containers SC 10. In early stages the seedlings need to be insulated from harsh cold drying wind. Once large enough hoping they will be fine. When large enough will pipe up water (misting system) to simulate fog that they are use to on the West Coast.
HI All, I am in Indonesia and have been trying to have my own nursery for Giant Redwood,Wellingtonia. i have bought these seeds from you and have manage to plant around 11 trees on my property. the area is ideal for giant redwood. i am in zone 9 and the get regular fog during the rainy season. my question is can i do vegetative propagation on mothers trees only 2 years old. Thank you
I have been told the Giant California Sequoia Redwood's seeds do not germinate without fire. Is this true?
No that is not true, However, Fires are essential to many seeds being released. Seeds can also be released by cone eating beetles and Chickaree squirrels. The cones that Chickaree squirrels hide underground for years, can be opened by fire in huge numbers. potentially releasing tens of thousands of seeds in just one location
this might be of interest . i sent some sempervirens seeds to my friend in reykjavik , iceland. he wanted to try growing them as it seldom goes below - 10. he has germinated 3 , and i have sent him some root grow mycorrhizal fungus starter as there is not much chance of a suitable root fungus there. if they live they will be growing north of the arctic circle.
I have planted three Redwoods at 950 feet in North Wales. Lots of mist here but some impressive winds at times. My arboretum is 18 months old now! Andrew
Hey there. You need to be misting often, everyday, several times a day. They need to be near the window, getting at least partial sunlight. Your soil needs to drain properly, with sandy loomy soil. i would also recommend vermiculite, perlite and coconut coir as a mixed soil along with some sand. once your sapling is an inch or two, it needs to go outside. Its not a houseplant and is naturally exposed to hot and cold elements. However, Coastal redwoods in hot temperatures require water, if there is no foggy conditions on a semi daily basis. Spray bottle works good
I have a Question where is the origin of the seeds , i want the oregon ones because im living in a more cold climate
Will it work with my redwoods If I put them in a paper towel (damp, ringed out) and out into a baggy and than the fridge, or just in a drawer to germinate. I’ve used this method before with seeds and it works really well.
Coastal redwood seeds don't require stratification. You can sow them right away in sterile soil mixed with perlite and covered with a thin layer of vermiculite. You can substitute vermiculite with perlite if you don't have any.
I have mould growing on my sprouting seeds.
Stop watering so much, add vermiculite to topsoil or repot into new soil that is sterile.
I'm having a nightmare.
Coastal Redwood Seed germination is 20-40% from VIABLE MATURE Coastal Redwoods.
Are there anybody who can help me about how cuttings could be propagated? seqouia giganteum? email@example.com from Turkey
Very thoughtfful blog
Brilliant blog, I'm loving every comment. I saw a redwood in our local university and fell in love. So far I haven't managed to germinate a single seed despite sowing months ago. That said I'm going to keep trying as any video I've seen of them just makes my heart skip a beat.
Wrap your young trees in Burlap sacks before it gets too cold. This will prevent the trees from being too wind wiped especially when it gets so cold
Through happen whatever significant. Development test country.
