I could not wait I noticed many pods turning brown, so I thought I'd post my method
1: I put one plant in the plastic trash bag
2: enclosed the plant in trash bag I inverted over a black dish(black to see any pollen action)
3: and beat the plant male kola with a pen (GENTLY lol)
4: many discolored grey and brown pods fell off into the dish ...with much pollen too!
5: with a Russian tea sieve(1-2 inch kitchen sieve) I added some pods
6: with the sieve over the black dish, using the back of a teaspoon I grinded the pods into the sieve
7: so the pollen falls into the dish, when all done about 6 teaspoons
8: I scooped it up, to the corner of the dish, and with a cotton bud?
9: then spent the next hour on my hands and knees applying the pollen to 3 favorite females, it was painful but well blazed
10: the phone rang and accidently sprayed the plants heavy with water, I should have waited 30 mins, better half an hour
(for the business of reproduction to be complete) ...so will have to re apply this whole technique again later ..bummer!
good luck
