Morning all.

Lately, ive been looking online for hints and tips from some of the more well known youtube etc boffins and trying to work out what advice is best with regards work on these particular trees at this time of year and heading on into summer.

If anyone could share their experiences and thoughts, be glad to hear.

1) Japanese black pines do not do to well in the UK (due to level of sunlight) and you you may struggle to get a second flush, so treat as a single flush pine. This is from one source but then i see elsewhere that Black pines in the UK grow vigorously ::dunno:

2) I see a video from a well known expert saying to cut ALL candles (even the very weak), not just those that are mid to strong.

Sorry if this has been done to death, did a search and nothing came up.

Mine grow OK and produce a second flush no problem. Yes I would cut ALL candles at the same time. My source for all this has been Ryan Neal at Mirai and it seems to work well for me. We are getting close to candle cutting time now. Some people say 1st June - it shouldn't be a "to-a-calendar" schedule of course but it's definitely very close to the time now. Just before/as the needles extend. If you leave it a bit later the second flush will be even smaller if that's what you're are aiming for. It's a refinement technique and isn't an appropriate technique for trees still in development.

Hi Gary, thanks for the reply.

Im new to black pines, just have a few scots pines and wouldnt describe myself as confident with pines, kind of been my nemesis back in the day when i started collecting.

I have a black pine here that is established with the trunk and branches in the right places, just now starting to develop lateral branches. Most of the taller candles are mid to high up on the tree. There are 2 very small candles on the bottom branch and these are the 2 im a bit reluctant to cut but still a few weeks of growing time left.

Ive also read that some folk cut candles on black pines in 3 stages from bottom to top, whilst others think this as overkill.

Glad to hear yours get a second flush, news i wanted to hear.

There is a candle at the top of the tree i will leave as i want the top of the tree to thicken up, it looks a bit stumpy at the moment.

With JBP, decandling is one way of balancing energy and creating ramification. If you don't cut the smaller candles they will not ramify through a second flush. The other thing to do is to needle pluck to ensure even quantities and distribution of needles on each branch. So with needle density equal and all candles cut, every part of the tree is of equal strength and of equal value to the tree. Thus the second flush will be a lot more equal across the tree. Of course apical dominance will mean the top will get stronger but you can redo the needle plucking later in the year if needed. As said this is for refinement so you may leave candles on branches that you want to thicken.

Scots pines are different and need different treatment so don't do this with them.

Not much luck here in Warrington with blacks or whites. I suspect it is simply too wet and they seem to die off. Scots, Jacks and Mugos, on the other hand, do quite well.

That could be a significant difference, worth taking note of. I'm in the south, with a south facing garden with a good natural wind break from mature trees and hedges, so it can get quite hot - we probably have an environment that suits them. Both blacks and whites grow well. I keep them well watered but in a free draining soil - Akadama, pumice and lava in a 1:1:1 mix as recommended by Ryan Neal. I hope they work well for you but if they don't, then it may just be the local climate.

Thanks for the reply.

I will see how it goes over the next few years and report back.

Had a good few days of sun here, they get the sun all day.

Thanks!

I have a Black Pine that I have to admit has been neglected badly for years as I had no idea with Pines how to care for them!!

It has very few branches- Those it does have are very long with needles at the ends!!

The bark is quite nice though!!

The trunk has a bit of movement too!

The candles are around 3" , I pinched the longer ones back a couple of days ago to around an inch which matched the shorter ones roughly, Was scared of taking them all off as I seem to recal that it could kill Pine trees as the old needles die and no new ones left to photosynthesise!

I actually thought of removing almost everything and leave the most pliable branch to wire in to a literati as mostly they're becoming a bit stiff now to move very far!!

It's been in the same soil for years too!! :oops: :oops:

Hello John, thanks for the reply.

I think some trees more than others folk need to keep a closer eye on, black pines being one of them.

When i saw your tree i thought Literati or perhaps with some branch bending and bud back, a great garden tree. It looks healthy enough up top.

Ive got several seedling black pines on the go at different stages and they do seem to be vigorous this year.

With the larger tree, just being cautious as dont want to ruin it.
