We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
I posted my database, but it got cut off, so am deleting this post. If I get time, I'll try again by breaking it down into increments that will fit into the space we're allowed in these boxes. For now, I just lost quite a chunk of my time. My idea was to post the germination information I've compiled so far in my database and to ask anyone else interested to do the same in this thread, so that by pooling our efforts, we could save ourselves some time hunting down this stuff.
Hi Anita, I've been sharing my research with PlantFiles for a few weeks now, if it's anything different or clarifying. One thing that makes my system so convenient for me is that the germination info of 100 or so species is collected into a single document, which is easier for me to refer to rather than dialing up PlantFiles on a one by one basis more than once.
If anyone compiled their germination data into a single document, I'd love for you to do it here, too, maybe we can save each other some time.
This research is involved, but once done, I will always have it, and the actual process of sowing and germinating goes more quickly and is more foolproof for me. Following are descriptions of the 3 lists I'm keeping, with the 2nd short one provided:
1) master list - alphabetical list of all my seed in which each entry has description, propagation & culture in detail. On any given day when I may germinate a group of seeds that share common germination methods but still have individual idiosyncracies, this is quicker to refer to than dialing up PlantFiles one by one.
2) List by germination code - Once I research as much information about a plant as I can, I just enter the name of it in Tom Clothier's list of sowing methods: http://tomclothier.hort.net/page48.html So, far, my list looks like the following (you can see how like gets automatically grouped with like, and I do adapt and fudge other germination methods to fit in it) (Depending on the seed, I use baggy method alternately on pot or filter paper. I'll have to go through this again and clarify that) (This list only includes the initial phase of germination methods that are complicated - for that I refer to the master list) -

12 Slow germ. - up to a year or more. Store seeds in moist sand in the shade. Check seeds often in the spring, and sow them all as soon as radicals appear.

15 Impervious seed coats. Nick, grind or puncture.
16 Pour hot water over seeds, let soak 1-3 days until swelling noticeable
17 Wash & rinse 3 times per day for 7 to 14 days.
List 3 is a schedule with respect to my last frost date. Because there can be so many ways to germinate a seed, or so many phases to the germination process, and life has a habit of lousing up the best laid plans, this is where it gets messy for me and I need the other 2 lists to double check this one and keep myself straight.
I may be in zone 7a, but we've gotten frosts here as late as May 5, so that's the date I use for myself - http://tomclothier.hort.net/ - scroll down to the bottom and click on Determining weeks before last frost in your area - Again, this is just a fill in the blank, using the master list as a reference
Hope someone else finds this helpful and would like to pool their efforts with mine. It's a work in progress.
Anita, thank you, that is wonderful. If I had enough seed, I'd try everything to see what would happen. Health issues are keeping us on a shoe-string budget, so Excel isn't available to me right now, but the other data was extremely useful.
Our library internet provider has been on the blink lately, but will keep updating my list when I can and eventually post them all here. Anyone else wrestling with this who might have a tad to offer too?
