... or How To Harvest Lithops Seeds.
I normally scrape lithops seeds out of a seed capsule with a needle and it works fine if the seeds are big (like lesliei's) or there are not that many. Harvesting tiny karasmontana seeds lately I had to realise it takes too long and hurts my back and eyes. I don't know any other method other than throwing the seed capsule in water, but without any help not all of the seeds detach. Combining the water bath and a needle I was able to get the seeds out very quickly.
First you need a small shallow bowl and a piece of wet paper towel fitting the size of the bowl. The piece of towel goes into the bowl, then you can pour water into it.
Now you need a pair of (scissor) tweezers and a needle on a stick (a pensil will work). Make sure to clean out every section of the capsule properly.
Once all the seeds are out you just take out the paper and put it somewhere it can dry (it helps to lay another paper towel folded in several layers under it).
To put the dry seeds into a paper envelope I use a white brush. I find the seeds don't jump around much and you can count them as you go if needed.
Sometimes there's a whole lot of seeds in one tiny seed capsule.
