I will be heavily root pruning one of my mulberry trees. The roots are Morus Alba-Tatarica. I intend to use these to graft numerous mulberry varieties.
Does anyone have tips they can share on how to use the roots to graft? I’ve already read most of the web sources on this so I would really value first hand information and informed opinions instead of web links. I’ve also root grafted in the past with mixed (aka poor) results.
Specifically—
- Does the root need to be cleaned thoroughly before grafting? I would assume so.
- Does the graft union need to be below surface during healing?
- Do I need to keep root zone warm? Heat mats? I intend to graft during cooler months. The soil doesn’t warm up properly here until July.
- Can I use a callus pipe for root grafting?
Also any grafting techniques that you used that worked better?
