Another tip: when you fertilize your 'pines', fertilize the bottom bracts....not into the crown....and don't use anything with a lot of salts.
We fertilize ours with Triple 14 or 16....and then after about a year, I use Bloom on them. Pines from Ratoons take about 18 months to fruit (at least around here). Ours live outside in 160" of rain per year...but they are planted in pure cinders.....
