Makeshift Greenhouse

It basically consists of a 2'x4' table, bent rigid wire, 1/2" wood dowels, 1"x2" board, 3mil translucent tarp, and a bunch of staples and duct tape. I'm going to have to find a more permanent solution than duct tape - it'll fall off within a couple of days, but the staples should - for the most part - hold it together until I find that solution.

Seed #6 - Branches
Moving Day

I had originally planned on keeping them in the lights for a long time, but changed my mind when I saw how the lights treated two of my older seedlings. I had a two-year-old and a one-year-old under the lights for three weeks. At the end of the period, the leaves had turned a deep blue-green color, and the trunks didn't seem as rigid. The color is an indication that the leaves were adjusting to find the best color to absorb the artificial light.
The color of a leaf shows the light waves that its chlorophyll reflects, and thus, doesn't absorb. Since the leaves were a little more blue than the ones outside, I can deduce that my lights are lacking in (at least) the blue spectrum.
As for why the trunks seemed less rigid - that may be due to there being no wind in my garage, that the light may not be bright enough, or that it's only really reaching the top parts of the tree, giving too little to the tree overall.
Anyway, the tree seedlings have spent two days in full sun with nothing but positive signs. The soil mixture is well-draining enough that I'll have to water these every day, possibly twice when it's really hot outside. I'm going to play it safe and keep the trees close to the house to protect them from heavy wind and rain.
In this photo are my coast redwoods, giant sequoias, and bristlecone pines.

Seed #6 - Transplant

When transplanting from a cel-pack, it's important to (carefully) use a razor to cut the plastic away from the root ball. These little plants are still so delicate. If you disturb the soil, it could tear the thin root hairs - if you're lucky enough as to not snap the stem first. When cutting, you need to remember that there may be roots up against the plastic, so try to keep the razor from slicing into the soil. You're probably going to lose a few root ends, but it's better than killing the seedling all together.

Seed #5 - Transplant


The transplanted seedlings are going to love their new soil. I have a few more that are ready to move - I'll post them as they move.

Seed #9 - Transplant

I then put together a well-drained soil mixture, consisting of:
- cheap potting soil
- vermiculite
- perlite
- sphagnum peat moss
- sand (just a bit)
This last photo is intentionally out of focus to show the soil mixture, rather than the seed leaves.

Seed #9 - How Quickly They Grow Up...

A great way to avoid damping off is to get the seedlings to grow as quickly as possible and to transplant them out of the cel-packs after they have a few sets of secondary leaves.

Grow Lights!

... Well, that, and coast redwood, bristlecone pine, dawn redwood, and red maple...
Seed #4 - I Really Need to Be More Careful

Tomorrow, I'm going to try the equivalent of open heart surgery -- I'm going to see if I can put just the right amount of soil around the base of the sprout to help hold him up. I have no idea what the chances of him making it are, but I'm not that optimistic. If seed #4 dies, I'm down to only five sequoias (from seeds).
It's getting more and more difficult to keep these sprouts alive. I might be watering them too much - or, maybe they're not getting enough light. Whatever the problem is, they're not talking. I'm done using spray bottles, that's for sure. Instead, I've found that watering them from underneath works really well. I fill the tray with about an inch of water, and wait for the driest cel-pack to moisten, usually after thirty seconds.
In any case, I'm not looking forward to another sequoia dying. I think it's time to order a few hundred more seeds, and really go nuts. If they're going to give up on me, then I'm going to fight back by bringing in reinforcements!

Time for Sun and Fertilizer
I think I've been coddling my sprouts a little too much. They're over a month old and haven't seen any direct sunlight. Each of them has a set of secondary leaves, and are seemingly healthy and eager for more growth. So, I've started giving them small doses of direct sunlight, and much more outdoor shade. I know I'm crazy, but I'm convinced that a few of my sprouts grew a tiny bit from their time outside today.
Also, since the soil is probably starting to lose its nutrients, I gave each seedling about a tablespoon and a half of 1/4 -strength fertilizer (24-8-16 water soluble from Giant-Sequoia.com). If they don't react negatively to the treatment, I'll continue to apply small amounts of diluted fertilizer every seven to fourteen days.
I also tried out watering the sprouts from underneath, which seemed to work well. To do so, I placed the block of nine cel-packs in an inch of water, and waited for the top to become moist (fifteen to thirty seconds). I'm going to try this out every other day, rather than spray the sprouts twice a day with a spray bottle.

Cold Stratification
It's been several weeks since any of my remaining sequoia seeds have germinated in their damp coffee filter baggies. Of the sixteen germinated seeds, I'm down to only six that are still alive. Most recently, my first sprout, seed #1 just shriveled up and died. As silly as it sounds, that really brought me down.
So, I'm down to six sprouts and about eighty seeds. I can either throw out the seeds, buy more and start over, or I can try to turn around the seeds I have and see if I can get them to sprout.
It's likely that a third of those seeds are still viable, but dormant. In nature, conifers have a clever trick to avoid entire crops of seedlings to dying off in a catastrophe such as fire or drought...they don't all sprout at the same time. One way to break this dormancy is to mimic natural conditions that the seeds would go through, such as winter coldness. This is called cold stratification, and can be achieved by placing the seeds in moist peat moss (or other mixtures) in a refrigerator at a few degrees above freezing for one to three months.
Note: this isn't normally necessary for vegetable and flower seeds, since they've been cultivated to grow without the dormancy. For more information and other seed-starting tips, I highly recommend the following links: Seed Germination and Growing Conifers From Seed.
I split out my seeds into two groups, then dropped them into sealed baggies, each with a few tablespoons of seed starting soil mix. I sprayed spring water into the baggies until the soil mixture was moist, and stored them away in the back of my refrigerator.
Waiting two months isn't going to be easy, but it'll be interesting to see the difference that cold stratification makes. After that time, I'll probably keep the seeds in the baggies until they've sprouted, then move the individual sprouts into cel-packs. The coffee filter baggies worked really well, but only for the initially-sprouting seeds. After a couple of months, it's hard to stave off mold and frustrating keeping the baggies moist.

Current State of the Union
When I first started growing trees from sprouts a couple months ago, I didn't expect myself to go this far. My original goal was to photograph each tree sprout every few days, so you could track its progress with tag filters. That worked for the first month. At this point, here's what has sprouted so far (with more seeds still to germinate):
- 20 bristlecone pines - (9 outdoors in rocky soil, 11 indoors in seed-starting soil) between newly-sprout and 2 inches high
- 9 coast redwoods - between newly-sprout and 1 inch high
- 1 dawn redwood - about 1 inch high
- 7 giant sequoias (from seed) - between 2-3 inches high
- 13 giant sequoias (purchased as 1-2 year old seedlings) - between 6-15 inches tall

Seed #14 - Further Out of the Soil

I thought I'd try a little experiment here. I just placed two toothpicks (not pictured) in an X across the seed coat, with the hopes to keep it pinned down as the stem stands up. Hopefully, later tomorrow, the plan will have worked, and the seed coat is laying on the soil, with the cotyledons fully exposed.
