Title: Deciduous from seed?
Post by: Yenling83 on January 21, 2012, 06:30 PM
I have a few different varieties of seed I plan to start this season.  I'm wondering about doing seedling cuttings with Deciduous-like we hear about with Black pine so often and if this will give the nebari the best possible start? What do you think and have you tried this yourself? 

Thanks

I have never done a full cut like on JBP.  I've gotten really close to it on oaks and baobab seedlings before.  I think it will be different for each species.  It is worth trying on a batch of whatever you have if you've got plenty of seed.  Someone else has tried it before and will chime in.

It works with most deciduous trees as well, however I normally just do it for short trees as it moves the first buds (and thus branches) closer to the nebari.

To improve the nebari, you will also want to place the seedling cuttings on top of something that will force the new roots to grow radially instead of down. We did a batch 2 years ago with a friend and the result is plenty of young material with a perfect nebari start.

thanks for the feedback, I think I'll try it about 1/3 of the seed.  I have not had good result from growing on tile or other things to flatten out the nebari.  From what I've seen, working on the surface roots during every re potting has a much better result.  By working on them I mean, spreading them out, cutting downward growth, uncrossing, etc.

I have tried this method of seedling cutting on Acer Palmatum and Cupressus Macrocarpa aswell just recently.  They all took root ok.

As far as timing goes i cut them about a week after the first top growth had slowed in growth.  Hope this helps!

Actually my friend made some clay root guides instead of using tiles... I'll try to find a picture ;)

Make a frame of wood to fit the top of your grow box. Fit the frame with plain window screen. Let the seed just start to break the soil and show just a bead of green, and then apply the frame to the top. make sure the screen is about 3/8 inch from the surface of the soil. Let seedlings grow for about two to three weeks and then remove the screen.

You will have the start of some seedlings with movement just not possible with wire at this early stage. Just experiment with 20 or 30 and grow the rest conventionally. You will come back again and again to this trick. It is interesting.

I root cuttings and plant seedlings thru the hole on in an old computer CD or DVD. I plant it so the CD is about 2 inches below the soil. When the plant base reaches the diameter of the hole. It swells around it and throws roots on top that grow radially, so you get a shallow root system and a fatter base. After a few years, the plastic of the CD becomes very brittle and breaks off easy. Some might stay embedded in the plant, but its below the main roots anyways where you would cut them off. I especially like using old AOL Cd's cause I hate them! ;D

Awesome idea Al, I had never thought of doing that!

I have tried doing seedling cuttings from Trident maples, and the cuttings worked but didn't give any benefit over regular yearly root work. It mostly just slowed the trees down.
