Pinus Densiflora Japanese Red Pine

Post by MoGanic »

Hi all,

I remember a while back either reading or watching somewhere about a significant difference in care requirements between JBP and JRP.

I cannot for the life of me remember where or how.

Does anyone here know what that difference might have been? Perhaps soil? Fert?..

Any help appreciated.

Red pines are similar in care to Japanese black pines but they are certainly not as vigorous. The major difference is only evident and significant at more advanced levels when you are totally candle pruning and needle plucking.

Do the candle removal earlier in the season, just before Black pines, and leave more needles when you are needle plucking for clean out prior to wiring in autumn and when you have just candle pruned in spring/summer as well.

Fertilising is similar but you just don't get the vigour and dark green of a black pine.

I see, I guess I just imagined it or it must've between two other pine species.

Good information regardless, thank you kindly for your time and effort Grant.

I think it would have been a comparison between two different pine species for instance JWP to JBP.

I treat them in a similar way but I do leave many more old needles on the reds.
In a Ryan Neil video I remember him saying that the older needles on a red pine are needed for hormones and the tree will get significantly weaker without them.

I think you're right, as White Pine is often grafted onto black or red as the roots are not strong enough to sustain them for a long period of time (we're talking hundreds of years which seems to be "not long enough" in Japan).
