The photo shows the flower bud on a 2-month old cutting. A cutting usually has 2 or 3 buds. Remove all the lower ones and let the top one to grow. The new growth is just like a branch on the old tree and therefore bear fruit the first year. I use a 2' stick on the pot (shown on the left) to support. When it reaches 4 feet, I cut the tip to force it to grow side branches.
