I saw this technique on TV many decades ago and later found out that in Tokyo there are thousands of City workers who have been doing this for hundreds of years for the many pines there. I usually wear gloves for this task as the sap is terrible, this was only for the magic of blogging. I also learned once, during a brief foray into bonsai, that this makes pines and conifers bushier by promoting more branches below the break.
The candles easily break, in a few weeks the needles will emerge.
In a few years you will have a tidy looking pine. I got these over 10 years ago for 2 dollars!
