Grafting seedlings made foolproof
« on: January 26, 2018, 04:09:36 PM »
Brief description of what your looking at.
1. soak seedlings/ this helps to clean and hydrate. 0min-24 hours (min-max range) I generally soak 5 minutes -1hr
2. Wrap your stock. The obvious leaves etc. must be removed first. 1 inch piece of parafilm or so is needed for this.
3. Piece for top of graft to hold scion/seedling in place
4. slowly stretch that puppy out nice and tight so it feels like saran wrap or slightly thinner
5. Put a seedling in your mouth to hold it in place/grab razor blade and slice stock to create a nice smooth surface
6. Place your seedling on cut surface/offset

7. Gently drape parafilm wrap over seedling and slowly bring all sides down without putting pressure on seedling itself. You may wish to hold seedling in place by placing a slight bit of pressure over seedling while drawing down sides of parafilm. After seedling is secured off center and without pulling on parafilm you may twist parafilm around sides to draw the seedling in tighter. Larger seedlings may get a little pressure or more man handling without fear. 1-2 week old seedlings may be crushed if you are not delicate.

8. Prepare your label and place label.

The size of the seedling used in this grafting procedure is the size I use when I want 99-100% of my grafts to take and I'm not rushing things.

The size you see already grafted and growing in the last slide... those were grafted at 1 week of age and came from the same batch of seedlings. I tend to graft seedlings at the 1-2 week mark when I don't mind losing a few or there is an albino/variegate that I want to speed up and I'm worried they won't make it. Grafts 2 weeks old give me a 95-97% success rate with this method. 1 week or less grafts give me 80-90% success rate on average. As with everything there are always other variables that may come into play to bring your success rate up or down with any particular batch of seedlings. Did the weather drop in temperature?

Was there a marked change in humidity?....not as much of a factor for parafilm grafting, but is important with non-parafilm grafting. Did I use a fresh razor blade for stock and a new razor for scions? A dull razor will effect your success rate. If using a separate blade to remove leaves and cut stock from scion... i.e. two blades are used I will tend to only graft 25-50 seedlings per blade. If I go away from my project I will discard the blade or use it only to remove leaves which will then give me 3 blades per graft.

I present pictures for how I wrap my seedlings for those that like that sort of thing. I am of the opinion that if your at least 5 years of age... you should be as good with these simple techniques.

Important: Do not crush seedlings. Place stretched out parafilm like a drape over seedling that is off center as in picture 1. Lightly pull down without exerting force on seedling. You can reposition one hand or get a helper to lightly hold seedling in place if you need to, but seedling should not move if no pressure is applied. As your wrap a bit at a time around the stock... your seedling will naturally be drawn into the stock. If at the end you suspect not enough pressure is on your seedling or your seedling is not secure enough... you may then make a light scrunching motion at the scion where you first wrapped the scion. This should draw your seedling down a bit more and create a very tight union, but be careful... it is easy to get that seedling union too tight. This will result in a smashed union and your grafted seedling will eventually turn to mush and or dry out.
