How to Stratify Hardy Kiwi Seeds?

plantlover13(5)June 27, 2013

Hello.I recently bought some hardy kiwi seeds. I know they need stratification, so how do i do it? i have taken the packet, stuck it in a sealed ziplock bag to keep out the moisture, and stuck that in my refrigerator. Will this do? also, can i overcome the need for stratification with GA3?

Thanks much

Do you know which actinidia? A. arguta appears to respond well to 3 months cold stratification while A. kolomikta may germinate better if given a warm moist period of a few weeks before the chill, then chilled, and finally brought back to warm.

In any case, placing the seed packet in the refrigerator doesn't do it, that's only storage - cool and dry is how you would want to preserve seeds, opposite of promoting germination. The cold/chill must be moist, you don't want to prevent moisture from breaching the seed coat. Put the seeds with a tsp or two of moist sterile sand, or moist sterile vermiculite in a zip lock, date it, and put that into your refrigerator. (harder seeds you would soak first, then place in the damp medium) When the suggested time is up, sow the contents of baggie, sand/vermiculite and all, no need to extract the seeds.

Hi plantlover,

Well, I've never tried growing Kiwi but I doubt that using GA3 would really help. In the past I've tried using GA3 on different seeds, and frankly I didn't see much difference in the germination times.

However, there is a pretty good web page (see link below) that may be helpful to you. What ever you try, I wish you the best of luck!


Here is a link that might be useful: Growing Kiwi from seed.

Oh, sorry, I missed the fact that you were trying to grow the hardy kiwi. The hardy type may need stratification. Hopefully someone who has grown them from seed will come along and offer more help.

Does anyone know how long dried kiwi seeds will stay viable at room temperature?
