Hi All,

A little while ago, I started grafting center cuts of T. bridgesii to T. pachanoi stock. I had a surplus of pachanoi and only a few arms of bridgesii. It became a game of how many bridgesii grafts could I possibly make without having to attempt areola grafts.

Grafting 1" center cuts has been extremely successful with very few problems.

Here's a step-by-step of the method that should be easy for anyone to do.

Please let me know if you have any questions, concerns, and/or suggestions.


Happy Grafting,
Hcc



Overview:
Cut your sections of scion into about 1" cuts.
Dip/dust the top with sulfur powder.
Put a folded up piece of paper towel on the top.
Tape the scion to the stock very firmly.
Wait till graft has healed (~2-4 days)


Step 1: Materials
Isopropyl Alcohol (IPA)
Spray Bottle for Iso Alcohol (not pictured)
Paper Towels (preferably the kind that are 1/2 of the regular size)
Masking Tape (Painter's tape) 3/4"
Sharp Razor Blade
Dusting Sulfur
Small Cup
Cutting for Scions
Cuttings for Root Stock

Step 2: Preparing a Workspace
I find that a clean, organized, thought-out workspace is key to successful grafting. When the cacti are cut they begin healing quickly. Also sulfur powder should be applied as quickly as possible. Being organized helps the speed of the process immensely.

1. Wipe down surfaces with IPA or other disinfectant

2. Put IPA in spray bottle and set aside

3. Put sulfur powder in small dish and set aside

4. Measure the length of your scion arm (In this example, 7")

5. Mark of 1 inch increments with a Sharpie. Leave about an extra 1/8" at the healed end.

6. Tear strips of paper towel, One for each scion

7. Measure out strips of masking tape, Two for each scion

8. Lay out a sheet of paper towel to work on and spray it with IPA

9. Fold up a piece of paper towel, tape it to the edge of your work space, spray with IPA (this is used to quickly wipe of your razor blade later on) [Pic Above, Far Right] Clean your razor often. I tend to clean it after every cut.

Step 3:Making the Cuts
You want to work quickly and safely at this point. The faster you can attach the graft, the more successful you'll be.

1. Slice off about 1/8" of the healed end of the Scion arm
Caution: Be careful with the razor

2. Take the first piece of stock and cut it about 3" to 5" long

3. Make 45 degree cuts at each rib of the stock. You want a "platform" left at the top that is above the skin.

4. Cut of 1" of the scion

5. Immediately dip the non-graft end of the scion in sulfur powder, wipe excess away with razor.
Caution: Read the Safety label of your dusting sulfur and take appropriate action

6. Lay the sulfur end of the scion face-down on your work space

7. Make 20 degree cuts at the each rib of the scion. Like the grafting stock, you want a "platform". The scion platform can be smaller than the stock platform.

8. At this point, you have a couple of things you can do to help the scion successfully attach:
     8.1. Trim the edge of the scion
     8.2. Make another set of 20 degree cuts at each place where the ribs intersect

Step 4: Attaching the Graft

1. Cut a very thin slices off of the platform of the stock. Repeat for the scion.
This gives you the freshest possible cuts to attach the scion and stock together.

2. Place a piece of folded paper towel on the sulfur end of the scion and put tape across the top.

3. Place the scion according to New Wisdom's explation of columnar grafting

4. Firmly press the "platforms" of the scion into the platform of the stock. I push pretty hard at this point, they really mash together. While maintaining pressure, tape the scion down.

5. Place the second piece of tape perpendicular to the first, press firmly on the scion, and tape down

6. Dust the graft with sulfur powder

7. Label the graft

Step 5: Wait

Wait 3 or 4 days to a week or more, until the grafts appear healed. Grafts seem to come out better when I forget about them for a week or two.

Here are some pictures of the original 7" T. bridgesii arm. 100% success.

I'll update with more pictures as these get older.

Happy Grafting,
Hcc

I had no idea you could graft without there being any roots on the root stock, it's not even in soil... that's brilliant

As discussed in

this thread, the main concern with small center cuts is healing the top of the scion before it dries out.

Sometimes as the graft is healing, I'll put small pieces of saran wrap over the top of the scion after a layer of scar tissue has formed. This seems to help slow down dehydration of the scion.

I'm thinking about experimenting with different methods of healing the top of the scion:

• leaving the paper towel and tape on for 1 week
• leaving the paper towel and tape on for 2 weeks
• super glue
• high humidity for a day or two
• anti-fungal foot spray
• paper towel (as above) then covered with saran wrap for a few days
• tumeric powder
• cutting the scions into 1.25" pieces and letting them heal completely before grafting (as per NW's recommendation)

I think I'll try two of each of the above with all the same scion and root stock to help keep variables constant.

Does anyone have any suggestions or thoughts?

Thanks,

Cinnamon? If you're trying turmeric powder you could try some other spices that have uses in the garden... although it may just dry it out...

Awesome guide man!! Thanks for sharing!! +1

And by the way, what I was saying was not to make all the cuts and let them dry first, but to let a cutting callus completely, cut a small section off and graft that, let the cutting wound heal again, then cut another section and graft, ect... After reading your method though I think how you are doing it is better. 

And I wouldn't advise putting trichocereus in high humidity. It will most likely not help them heal, but promote mold and other fungal infections.

This is a peruvianus center cut grafted on a PC pachanoi that I got from happy recently.

I've been playing around with a similar idea with just a few differences.
I've been using various stocks and trying to use rooted ones to get them off to a faster start. In addition to the PC pachanoi, I've also used cuzcoensis and spachianus. Spachianus has become my preferred stock due to avaiability but they're all about equally good to me.
I've used two inch scions but I'll probably drop down to one inch also.
I've done similar to New Wisdom's suggestion above to graft one scion at a time from the donor. So from a rooted and growing plant, I'll cut off the 2" tip and graft it, wait a week, cut off the next 2" and graft it, and so on. That way the scion only has a fresh cut on one end at a time.

Hcc's traded Trichocereus grafts. Nice work!

Uh Oh, it looks like that pup may knock the whole scion off!

If it gets any worse, you may want to cut that pup off. The smaller one will take over at that point.

If it falls off, let me know, I can make another one for ya.

Very awesome idea! Looks like it certainly is working! I have about a crap load of PC pedro...I should grow some balls and try grafting! I've been far too scared for too long and its about time.

This is BRILLIANT!

@MadPlanter, I'd suggest starting with tip cuttings. They're very easy and rewarding.

@the folks who posted the photos I requested: Thank you very much! Somehow I didn't take photos before sending em off. Keep us updated!
