[quote=altoids]When plants grow, I assume a lot of their energy goes to making roots. What would happen if after harvesting a plant, and leaving the roots in the soil, you grafted a clone on top of the already formed roots? Would it work?

If you harvested all vegitation the plant would struggle to survive.

You might try taking two varieties of seed and plant them together as the roots will graft naturally under the soil and you can make a weaker blueberry stronger by growing it with the Afghan like I did. My blueberry was bumper but the Afghan was smaller so when strengthening one variety apparently it weakens the other. I suppose the Blueberry was sucking from the Afghan root structure. No the Afghan was not a Blueberry nor was the BlueBerry an Afghan and the two plants were indivdual plants with a common root structure. Something I tried so I thought I would share. When I did three plants like this they all were weaker plants. Of course I am working with seeds not clones and using the same 5 gallon pot I would use for one plant. Roots may have bound causing the decline in the Afghan too since there were two plants growing together.

My next experiement is going to be Blueberry mother's clone, grafted to an Afghan Mother. I'll then clone this grafted clone, to see if the Blueberry clone grafted to the Afghan Mother displays any significant improvements to yield and durability when it is cloned. I'd like to think this would allow me to cross strains without pollenating anything. I'll get back to this with pics after I see the results and can share them. Sure would be cool to get a 3ft Elephant Dick Blueberry Bud! If I get one I'll share the results with you...
