I have asked Jonas this question in a private message and with his approval I am addressing it to everyone.
I asked Jonas where dose he get his seeds from and dose he have a good source for variants like Mikawa or any other good one that he can address me too.
I was trying to contact growers in Japan and had no success so far. I thought I might have done something inappropriate but I was informed by my teacher that it is a very busy time in the year in the Bonsai industry.there are a lot of auctions and prepping trees so this might be the reason for the unavailability.
this was Jonas reply:
"Hi Shay - good question. I don’t have a good source for pine seeds. I’ve bought them from vendors at shows in Japan and from the growers during visits to their nurseries. I’ve also collected them from local landscape trees that have good bark and needle characteristics.
As for seed quality, it can make a difference where the seeds come from, though if you don’t know where exactly the seeds come from it’s hard to know what you’re getting. I too like Mikawa, though I’m also happy with the local seeds I’ve collected.
I don’t know that asking growers is rude, though I know from experience that not everyone has seeds or is set up for selling and shipping them. If you can find a broker for any bonsai related items from Japan it’s worth asking.
I’ll be curious to hear if others have suggestions."
So, dose anyone here have a suggestion?
