I finally ordered some Pineberry seeds, but they say to keep them in the fridge to germinate better for two weeks--my question is, if I keep them there for longer, will it damage the seeds in any way? I'll be moving in a couple of weeks and I know they won't be seedlings by then but this place isn't really set up for growing anything at this point.
Am not altogether sure what you are asking here yellowbird
Are you trying to get your Strawberry seeds to germinate in the fridge or are you storing them in the fridge, so that you can sow them after you have moved ?
Strawberry seeds, which is what your Pineberries are, don't normally need, to go in the fridge in order to encourage them to germinate, if they are sown at the correct time of year, which is Autumn. The fluctuating Autumn/Winter temperatures, break the seeds dormancy, naturally.
Strawberry seeds can take quite a while to germinate, anything from 6 to 10 weeks maybe even longer.
Seeds purchased from a Seed Supplier are best sown as soon as possible after receiving them, as you can never be sure as to how old the seeds are, but a few weeks either way, won't make much difference.
Any seed is best stored in a cool dry place and kept at a constant temperature. The optimum temperature for storing seeds is between 2 - 16 degrees centigrade.
It is thought that anything below 2 degrees or freezing the seed, can kill it, by bursting the seed membranes.
