Floating/sinking Ricinus seeds

Post by weve » Sun Feb 28, 2010 5:19 am

Edit Apologies, :oops: After searching found there is already a recent thread about this (Must have somehow missed it!) Its here:

Hi
Got round to my ricinus seeds (giant green, i think) harvested in early Nov.

Soaked them whilst the M.P. compost (brought in from outside) warmed up a bit. Initially they all floated, then after a few hours about 60% had sunk. The others never sank even after 24 hours, altho' they looked exactly the same

Wondering, is this an indication of viability?, and if so, which way round? I planted the floating ones seperately to see if there would be any difference in germination, but now, stupidly :oops:, i've got them mixed up (Duh!).

If it does make a difference, it's a good method of sorting the "wheat from the chaff", especially as i have many more ricinus seeds to plant.

just wondering................. icon_scratch

If I disappear mid-thread, please don't think I'm being rude, I'll be away working with no internet access.

I dont pre soak Ricinus but in general a sinking seed is a good sign, dont discard floaters but again in general they are usually the failures.

What I meant by that is why not sow them anyway, what do you have to lose?
