Hi All, I am trying to store a mixture of catgrass/oat seeds and dry soil for convenience so I would have to just scoop a cup of the mixture into a bowl and simply add water. I am noticing that a 2-3 month old soil-seed mixture is no longer germinating. Does this mean that seeds die if stored in dry soil? Or could there be some other reason? Will appreciate insight. Thanks!
Interesting! I would have guessed that "dry soil" still has much higher humidity than "dry seeds". If the seeds were stored "too humid" for a few months, they might have lost v igor. But oats and wheat? Dead in a few months? That is surprising.
Have you tired picking out a few dozen seeds and sprouted them on a coffee filter, just to see if they come up when coaxed?
Is it real soil-soil or a sterile soiless mix? I don't know what happens to soil organisms if dried out and kept indoors.
Were they germinating OK this way for the first 2 months? Maybe they dislike being burried so deep when mixed all through the soil.
