Id cable the two. reduce weight on the leaner and also prune the dominant stem to allow more sunlight on the back side of that leaner to encourage more growth in reverse of the lean. Thats one of the reasons it's leaning in the first place.
100% true--directional pruning does not work if you do not clear some daylight in the direction you want the branch to grow in.
Wease, thanks--that Dendro is a fun guy. The funnest part is, all 8 of the storylines I've done were from real life jobs, and it's a whole lot more fun than writing appraisal reports. Attached are the author guidelines for the Dendro series, in case anyone else wants to write one. The door is open.
re the hardhat, yeah it gets a bit snug now and then, but I figure that if you do not have self-confidence, you cannot succeed in this line of work (or any?).
"I noticed no one has mentioned the installation of a bracing rod in addition to the cabling.
Just curious is that because of the size of the stems, the resulting wounding to the trunk and introducing a pathway to the heartwood for decay, or has this practice fallen out of favor?"
Not out of favor, only applicable to large cracks that cannot be stabilized by cabling. I use wirestops on cables, so I only have to drill a hole big enough for the cable. Smaller wound in younger tissue means less rot, I'm thinking.
If this stem is >20" below the split, the BMP's call for a 3/4" brace rod. Overkill imo, unless there is a severe crack. All the more reason to post the pics from the angles Ekka described.
