I think it’s important for us in the US to divide pines up into two categories in our minds-One Flush and Two Flush pines. Talking One Flush vs Two Flush, I mean One Flush of growth vs Two Flushes of growth per year. Using traditional Japanese species of trees-Black Pine and Red Pine would be 2 Flush and White Pine would be 1 Flush. If you de-candle a tree in summer and it shoots out new growth after cutting the candles off, then it’s a 2 flush pine. If we de-candled a White Pine it would not throw out a second set of buds during the year and likely get very weak or die.
I think this is important to note because we are still figuring out our Native Pines here in the US and the correct way to reduce needle size, promote interior budding, keep them healthy, etc. There are still several native pines out there that deserve more of our attention. I think it’s just a matter of time before we figure out some new native pines to collect and work on. I have a few questions related to this:
1. Am I using the correct term, is there a better word/term than Flush?
2. Do all pines fall into the category of either one flush or two flush?
3. Do all high mountain pines tend to be one flush and all two flush tend to grown naturally at lower elevation?
-White Pine and Ponderosa are from the High Mountains and one flush, while Black and Monterey Pine are Coastal growers and two flush.
