Please keep this updated Jacob as things develop.

I knew cuttings from a witches broom will produce clones the parent broom but do the seeds from a broom also grow same type plants? That is interesting.

I've read that February is the best time to take Tsuga cuttings but then other reputable articles say that Softwood, Semi Hardwood and Hardwood all work.

I'll be doing a total revamp on my set up for next year also.

I think it's because the more I learn, the less I know, if that makes sense. ;o)

Hey Bill thanks for the the help. I’ll keep things updated.

I’m almost done working on the new cutting specific propagation chamber so I’ll have two chambers. One with blue LED, heat mat, and hopefully a misting system. That chamber will also only be 12” tall so the light can be closer to the cuttings. LED should also make it easier for me to control the temps. The other chamber I’ll use mostly for grafts without the misting just a humidifier. I’ll put some cuttings in there too, just to widen the possibilities of success.

I read through an old thread that mentioned successes at times throughout the year. The broom is so easy to access I might try taking 5 or 6 cuttings in June, but the vast majority of my effort will be in winter. I’ve been in touch with someone who has had success rooting Tsuga brooms. Things are pretty straight forward: Dip n grow, mist, bottom heat, cool tops, wait 5-6 months. He does his in winter.

I just want to be sure my due diligence is done and that I’m ready when the time comes.

Here is what I have so far

It’s roughly 2’ square. I will just use duck tape and plastic to seal off everything. The frame and base are all PVC and the top is plexiglass. I like PVC over wood. It’s still fairly inexpensive, but no rotting or fungal issues. I don’t glue most of the joints so I can take it apart or make adjustments later.

In my trials, I've learned the importance of 'Super High' humidity. Nothing seems to happen without it. Having a mister is great! I have that on my 'wish list'. Plexi-glass & PVC, easy to clean and it will last forever, good call!

After Christmas is a good time to do this stuff and by 5-6 months, growing season is here. Keep up the good work, we'll be anxious to see how all this comes out, then you can tell me how to do it. :-))

4-30-19 edit to add link: Here is an interesting read on rooting in general.

That's exciting news. Thanks for sharing it with us. I'd love to see a pic of your whole set up with cuttings in-situ.

Ditto!

That is one cool looking broom. :-)

Way cool...
Looks like you found a nice one!

Excellent. I'd have given little chance that hemlock cuttings would root, but you've proved otherwise.
