I live on 5th in HPP and have 1 avocado tree thats about 3 years old thats seems to be growing nicely. It's now about 12 feet tall...but no fruit yet. Avocados are very tempermental when planting (they don't like their roots disturbed). They need a hole about 2 feet deep and 3 feet wide if your planting a grafted variety and make sure it has excellent drainage as avocados will die quickly if it becomes water logged. They are also very heavy on fertilizer (about every 6 weeks for the first couple of years. Cinder soil mix is probably the best...but it will probably grow in cinders only if you mulch the top 3 inches. Salt from the ocean hasn't been an issue so far.
