About my seed-starting info
About my seed-starting directions
I only give information about MY OWN experiences with starting plants from seed.
If none are listed, Tom
Clothier's seed-starting pages are always a good start.
On my plant portrait pages, seed-starting information can be listed in two
places: in the table up top, and often in a separate details table further
down the page.
The listing near the top is a quick description of a method that has worked for me,
or sometimes an observation about volunteer germination in my garden. In these
directions, "cold" always means "cold
moist stratify in refrigerator". Depending on the method you choose,
this could be in a baggy with moist sand or filter paper, or in a sown pot.
Usually, just putting the dry seeds in the fridge won't be good enough.
"Warm" means room temperature (66-72°F,19-22°C).
"Bottom heat" means warmer than room temperature (75-80°F).
This entry is more or less free-form, and may not give you all the learnings
I've gathered from my experience. For that, you may need to look further down
For many plants, I list details of specific sowing trials. Let me explain
with a few examples of how to decipher these:
2003 Seed garden '01. Baggy 35F (12w; 10%G, 11w) - 65F (55%, 6-10d)
means: Results for the winter/spring 2003 sowing season. Seeds were
collected in my garden in 2001. They were germinated in a baggy, starting
with a 12-week cold treatment, during which 10% of the seeds germinated at
the 11th week. They were then moved to my basement (at 65F), where an
additional 55% germinated, starting 6 days after moving and continuing for 4
days. Unless specifically indicated, the seeds did not receive light.
Note: the days to germination for a baggy method are when radicles (seed
roots) were first observed. If sowing into containers, it will be at least
a couple days longer before you'd see seedlings sprouting.
In general the temperature designations for the baggy method are as follows:
20F - baggy was kept in the freezer
35F - baggy was kept in the refrigerator
65F - baggy was kept in the basement, in the winter months
70F - baggy was kept in the basement, in spring
75F - baggy was kept in the basement, on top of a shoplight to provide bottom heat
2004 Seed from '03 trade. Pot 65F (10w) - to outside (mid-Jan). Germination
noted mid-Apr, total 33%
means: Results for 2004 sowing season, with seed obtained in a trade the
previous fall. Seeds were directly sowed to a pot, which was kept at basement
temperature for 10 weeks before setting outside in the middle of January. The
first seedlings appeared in the middle of April; a total of about 33% of the seeds
yielded viable seedlings.
All of these germination notes are just my personal observations. Please
let me know if your experience is different.

|ross larson||Aug 19, 2011||I purchased seeds(sutherlania frutescens) and tried to germinate in wet paper towel. 1 in 40 germinated. Bought 40 more seeds. Microwave water till small bubbles. Take out and immediately stir seeds into water. After cooled down put seeds in wet paper towel. 80 percent germination. |
Goes to show how some seeds really appreciate extreme conditions in order to germinate!
