Q.Layering or Grafting Camellias
How do you layer or graft camellias?

Hello. Camellias are not a grafted plant. Grafting involves 2 species merged together: one's roots to another's top to help the plant live longer and/or support special fruit, as in most fruit trees, pecans, etc.
The best success for layering would be to find a branch (or many) long enough to lay down on the ground, cover with a few shovels of soil allowing for at least 6 inches of top growth sticking out of your new mound. Then, months later, (or even better a YEAR) cut your new baby away from the mother (close to the mother to allow for possible 2 plants from each rooting).
Camellias produce a surprising number of seeds.
