I have one in a pot that I started from seed as a kid that will be 49 years old next Spring (2012).
Grapefruit trees.
no
they live as long as they want
The lifespan of a grapefruit tree typically ranges from 30 to 50 years, although some trees can live longer under ideal conditions. Factors such as climate, soil quality, care, and disease resistance can influence their longevity. With proper maintenance and care, including pruning and pest management, grapefruit trees can remain productive for many years.
yeah
Maple trees typically live for about 100 to 300 years.
Gum trees on average live to be 400 to 900 years old. However, some gum trees can live to be much older than this.
trees or buildings
graft a better variety on it
They grow on trees, just like oranges and lemons.
Norway spruce trees typically live for around 150-200 years.
Giant sequoia, golden rain and grapefruit are trees. They begin with the letter g.
