Look for fruit tree varieties that are known for their resistance to common diseases and pests. For example, some apple varieties like Liberty and Enterprise are resistant to apple scab and other diseases.

Choose fruit trees that are well-suited for your specific climate and soil conditions. Consider both temperature ranges and water availability in your area. Native or locally adapted varieties tend to be more resilient.

Seek fruit trees that require minimal pruning, fertilization, and pest control. Some varieties, like certain fig and olive trees, are relatively low-maintenance and can thrive with minimal intervention.

Opt for fruit trees that are drought-resistant, especially if you live in an area prone to water shortages. Olive trees, for example, are known for their ability to withstand dry conditions.

Look for trees that can grow in a variety of soil types. Trees that can tolerate slightly acidic to slightly alkaline soils and have good drainage are generally more adaptable to different environments.

Research the typical lifespan of the fruit tree varieties you are interested in. Some trees, like certain types of citrus and figs, can live for several decades to over a century under the right conditions.
