The J.B.P. seed from the packets, packaged in Japan, will after 24 hours of soaking, generally germinate in 10 or so days. [ no need for refrigeration ]
Some J.R.P seed from Amazon, was put into hot water and left to soak for 24 hrs, germination started in 3 days and at a surprising 100 %, the last seed [ of 7 ] is now dropping the seed capsule. Only time will tell if they will adapt [ 1st time ] and if they are indeed J.R.P.
Also testing J.W.P., if this germinates, there will be much rejoicing. Last effort lasted two years, was an accident, and eaten by ants. Trying again.
Have only have thus far followed what is Bonsai Today, but as you may know we have a few differences with the response of the J.B.P, no candles as seen in the images. Only really short 1" to 1/2" candles, situation might be, after some discussion with English growers, too many buds allowed to develop. So new technique being tested.
Seems that J.B.P. candles in August to September for us.
Very healthy specimens, thus far.
Fingers crossed.
Good Morning.
