Over the years while growing black pines I have always strived for more buds. Each year i tried to get back buds to form and most times I was successful although sometimes the tree I was working on would show signs of promise and then wave them in my face as it took them away again.
What am I talking about? I am sure you have all seen them; those small buds that form and give you hope, only to swell but never open, and then after a few seasons growth, wither and die.
As far as i can work out, these are needle buds and or weak adventitious buds that for what ever reason can never really get themselves into gear. Even after candle pruning the rest of the tree theses buds often still sit and do nothing. The most frustrating thing about these buds is they always seem to appear right where you want them which makes seeing them die all the more difficult.
I have tried a number of methods to awaken them but none have worked. I have had them in both shaded locations and spots where they get full sun, on bottom branches and in the apex, on strong growth and on weak. Nothing seemed to work no matter where they occurred or what I tried.
But there is still hope. At the convention a month ago Ryan Neil talked about these buds and passed on a technique I had not heard of before. He said these buds could be awakened by slightly damaging them with a scissor cut done at the same time you candle prune. That is to say that when you cut the candles, you also make a small incision into these sleeping buds. He said it was this damage that would trigger these buds to put out a flush of growth at the same time as the cut candles re-grow their second flush.
As we in winter at the moment I have not yet had the chance to try this method out, but I look forward to trying it this coming summer. Hopefully it is the answer to this annoying sleeping bud issue.

Hi i know exactly what you mean by damaging the bud but what iv learnt from this past season and not on a black pine i done mine on my bosnian pine im currently bonsaing and the damage to the bud didn’t do anything i dont think but i made a later insission just under the bud or above and this has worked for me! I waited till start of August when i pinch and made the insission then hopefully you might get a lucky break with this you can only try it id took the chance as u don’t notice it oh i done it with an exacto craft knife its very thin sharp and sterile u get them for pennys 3 for a pound in poundshop etc wharever you are great tip from ryan neil wish i had a photo now to send u lol good luck

Hi Douglas, I tried damaging the buds at de-candling time this last season and didnt see any real changes. I will update with a post on my results in the coming months. Thanks for sharing your techniques, ill have to look into them.

Just make sure u use a pk boost for potash i use and test different fertilisers and iv falling inlove with chempaks high potash feed iv got a Chinese elm thats always been a bad grower no matter what i do this thing just wouldn’t bud since last winter and all through this summer the cambum layer is still all soft n green but the whole year including summer iv had nothing from it i brought it indoors for an experiment under the growlamps still nothing its been hit with high nitrogen feed and a 20 20 20 fully balanced feed n nothing bought the high potash and used it on all my trees and boom that’s done the trick my elm redwood, beech , ficus’s n maples love it and respond very quick i have a shimpaku that is just budding back everywhere and a Japanese maple and cooper beech all budding back and giving fresh growth just now! But yeh 8f the trees struggling id suggest a high potash feed its amazing what this nutrient does fr the trees i was shoched at the results i didn’t think it would be such a responsive feed for them!, i know it sounds far fetched i thought that what difference would it really do u know but just give it a shot u’ll see what i mean thanks and hope this helps
