Title: Growing Pines from seed indoors
Post by: gtuthill on June 13, 2012, 10:40 PM
Hello all,
Last spring i grew some pines from seeds for the first time.  Not a scientific test, but i started some outside and some inside just in my kitchen in a bright spot.  The indoor ones seem to do better and i could keep a closer eye on them.  After doing the seedling cutting (end of spring) I have put the ones started outside to grow and get more light. Like i said not scientific but the ones that started indoors are nearly twice the size of the ones planted outside.

So this autumn (our April) I started some more with the idea of keeping them over winter indoors, then put them out in the spring, giving them a 6 month head start. 

As it has become colder and less bright inside, I thought i might try keeping them under lights with some artificial heat.  I already had some parts i thought would work and after a couple of weeks the results are looking good.   Air temp is 20-30C and total of about 20W of light.  There is some air movement from fans as well.

here are some pics. They are P.Contorta, P.Densiflora, P.Sylvestris and then a close up of the contorta again.  P.Sylvestris seeds were planted 10 days ago.

Hello to you,

you may wish to also try the Japanese black pine. I live in the Caribbean [ West Indies ] and there is no chance of winter. Our lowest temperatures are around 19 to 18 deg.c,
The J.B.P. thrive, but I have them in full sun. Still, with very bright light and a light breeze, they might do well indoors ?

Anyhow, best of luck.
