October 2019 Graft Update: How To Graft On Cereus Root Stock Part 2

How To Graft Harrisia jusbertii On Cereus Root Stock

This applies to medium to large sized scion graft. Cereus hildmannianus serve as a great permanent root stock, It wasn't the fastest but might last longest compared to others.

Step 1

To begin with, get a decent root stock

Cut the top part of your root stock, it can be the top 2-4 inch and try to match it with scion middle ring, if your scion's ring bigger then cut another inch until they match.

Step 2

Cut your scion and make sure it is a level cut. Bevel the edge to reduce the risk of detachment.

Make sure the ring is similar in size to get better connection between scion and root stock

Beveling the cut edge is optional, but I always do so to prevent two complications later on. One is the risk of cut surface to dry and shrink.

Step 3

Match their cambium ring, as long as they touch each other; the graft will work well. Makesure the stay moist, never leave them too long or they will  dry up and shrink or sunken.

Provide pressure between scion and root stock. I use plastic food wrap and rubber to hold them together. Cereus root stock has thick long thorns that can be use to hold the plastic, but additional rubber use can reduce the risk of losing pressure.

Pull the plastic and make sure it is fittingly tight, not loose but also no too tight. you can test the scion after attaching plastic cover, if it shift to any direction; adjust the holding pressure.

Do your final adjustment if needed and left them under shade for a while. the advantage of using plastic wrap is they retain moisture from cut so they don't shrink quickly. 

Hope this explanation helps.
