Tip. Yes, you can grow a nectarine tree from the seeds of that nectarine you just ate, but the pitfalls are numerous, and you won't know what kind of fruit you have, if any, for several years.
How long does it take to grow a nectarine seed?
As with other stone fruit trees—cherry trees, plum trees, and apricot trees—growing a nectarine tree from seed takes three to four years to produce fruit.
How do you grow a nectarine from a cutting?
Pinch off any leaves from the bottom of the cutting. Put the end of the cutting in the jar of liquid rooting hormone, letting it soak for 12 to 24 hours. Put the bottom of the cutting in a high-quality potting medium, planting it 2 inches deep. Tamp the soil, then water it until it is evenly moist.
