I have this weird thing about growing trees from seeds. Typical like to grow fruit trees, but there is something cool about growing the largest trees in the world. Since there is no nursery in Georgia as I know that sells Coastal Redwood I started from seed. Plus I think it makes it slightly more personal to get a tree started from seed. If you do want to skip the germinating process and get a year old tree they sell them online.
Coastal Redwood trees grow naturally in California. They are apart of the Sequoia genus and cypress family. Other names are giant redwood and California redwood .They can live up to 1800 years and reach 380 feet (tallest).
This is my second attempt to grow these trees. Last year I tried to grow Gaint Sequoia and Coastal Redwood. The Coastal Redwood was easier for me, because it is required to put the Gaint Sequia seeds in a fridge for like a month, then after that they are fairly slow growing. I was pretty impressed the growth rate of the Coastal Redwood. Last year they died on me because I place them outside too early, too much water, and too much fertilizer. I did have one lived that got a good size ( almost a foot tall and wide), but the lawn mower cut it down 3 times. The third time the lawn mower hit it died on me.
I order the Coastal Redwood seeds online. They are fairly cheap at around 4 dollars for 20 seeds. Seeds are suprising small for such a large tree.
The only requirement for these seeds to germinate is dirt and moisture. Light at first is not a requirement so I place them under my bed till at least one germinated. I used a storage bin that I bought at Wal-Mart to hold the pots and trap any extra water. I think it is important to use some good store bought dirt for this. My previous experience with other plants its worth springing for some good dirty and not some dirt in the yard.I used Miracle-Gro to grow my Coastal Redwoods. I am sure there is some other dirt that is better for these, but I am too lazy to research that and they seem to do fine in it. I water them roughly once a week, or when the soil feels like it is getting dry
Please excuse the filthy container and the match in there, I was using it for comparison.
After roughly 3 weeks.
I planted the Redwoods early December 2010 and now it is early January. I have one that has is has popped out of the soil and another one that is extremely close. When I planted them I put 2 seeds in per spot, so i have a roughly 22 seeds planted here. Based on that, 10 percent germinated in 3 weeks. Since then I have placed them in the window seal. I will try to add some updated picture in a few weeks.

Similar as last year I started off with a handful germinated Coastal Redwoods and ended the summer with only one. The main reason for them dying on me this year (same as last year) was moving them from indoors to outdoors. They seem to really hate the outdoors after being indoors. They will brown after a week of being outdoors. I would suggest to either germinate the seeds outside or easy them outside the best you can. For example put them outdoors for a couple of weeks in a very shaded area that only receives a couple of hours sun daily.
Another suggestion I found out was that they enjoy water a lot. In my experience they are hard to over water and seems to grow faster with more water (within means).
Here is updated photos I took today (9/9/11) of the last standing tree.
Another Update August 13, 2012
Here is an update on my potted Coastal Redwood. There is some brown specks on the leaves and limbs that I have no idea where it came from. I added some fertilizer to it, so hope it will help.
I have now moved it to a pot 3 times the previous pot. When I removed the tree from the pot there was a good bundle of root at the bottom. Now the roots have plenty of room to spread out. I did noticed there appears to be some smaller trees around the base. Not sure if they are actually individual trees or part of the main tree. I will probably add mulch to the pot for aesthetics. The tree is leaning pretty bad but I think that is due to the tree leaning toward the sun and having little light in the backyard. I am going to try to straighten up the tree. Stay tuned for updates.
