Many types of seeds require a cold stratification process
before germinating, in nature, winter takes care of this
process, the cold telling the seed that winter is upon it, and
the warming soil triggering germination.
In many nurseries, seed trays are exposed to the cold during the winter, again allowing nature to handle this process, but for many gardeners, this is either not practical, or they do not live in a region that has cold weather, for them, cold stratification is the only way to trigger seed germination in certain species.
In the past, the most often used practice was to pack seeds
in damp sand, and put in the refrigerator for the required
length of time ( time varies from species to species, from a
couple of weeks, to a few months ).
The problem has always been, what moisture percentage constitutes "damp" and what percentage is simply "wet"?
The proper amount is moisture is critical, too much and the
seed will literally drown in place and start to rot when
removed from the cold, too little and the seeds receive little
benefit from the process.
Seedman has removed the guesswork from this process with the Seedman's Cold Stratification Kits for Seeds. We use a precise system of measuring media ( sand replacement ) and water to produce the perfect cold stratification process.
Instead of sand, our kits contain a blend of filtered coir and powdered hydrogel and a measuring spoon. We also provide 3 inch by 4 inch zip lock pouches with "write on" panels to place the seeds in.
To use, you simply add 1/2 ounce ( blue measuring spoon
provided holds 1/2 ounce volume ) of the coir/hydrogel mix to
the 3x4 zip lock pouch, then add the seeds and shake to
disperse the seeds evenly into the media. Then add 1 ounce ( 2
of the blue spoons ) of distilled water to the pouch, close,
label the bag with a pen ( white writing area on zip lock pouch
is easy to write on ), and place in the crisper section of your
refrigerator for the required amount of time.
The coir/hydrogel media will absorb the water and will swell slightly. Once the water is absorbed, the media is the contains the correct moisture for optimum cold stratification, it will not hold too much moisture against the seeds, and evenly distributes the moisture throughout the package, unlike sand, which can have wet/dry spots.
The Seedman's Cold Stratification Kits for Seeds comes
8 ounces of Coir/Hydrogel Media
16 ea. 3"x4" zip lock pouches with write on panels
1 ea. 1/2 ounce measuring spoon.
With this kit, you can perform 16 cold stratification's at once, or do one at a time whenever you need to, and the packets take up very little space. The kits will store well for years untill you need them.
