Propagation of Fruit Bearing Trees by Air-Layering
Awesome how to on cloning your tree, fruit and other trees can be cloned this way rather than growing from seed. Antoni Raj over on Instructables walks you through the process as he clones his sweet lemon tree.
I had never seen this done before but I think it is amazing that you could clone a fruit tree and be expecting it to fruit the following year instead of years from planting seeds. Very cool.
