Mike,
K is 56 in February and I will be 55 September - 2018, go for it.
Also that cut the seedling bit under the cotyledon, maybe for getting low buds on the
the J.B.pine, we use the technique for Tamarinds.
The J.B.pine grows surface roots without any encouragement.
Also you may wish to try hardwood cuttings on your Scots / Scotch pines, when they get
a bit older. We use the cuttings now, and get buds everywhere.
There is a stage where you grow out the J.B,pine to say 3 feet and cut back to 3 or 4 inches.
It will make the pine start all over in buds.
Then you grow new branches for placement [ the 1 , 2, 3 ] and further trunk thickening.
By the time you cut-back, your trunk should be around an inch to inch and a half.
Some seed can do this in 3 or 4 years, and in a 3 inch deep x 10 inch wide earthenware
,porous, pot.
I can transfer info, as we go. Also ask Mr. Valavanis as he grows Scots pine.
Good Luck,
Good Day
Anthony
J.B.Pines grow in zone 10 by the sea, we are so lucky.
Now how about we do some Caribbean or Caribbean / Honduran pine seed ?
