Reason 1: Exposed to Gamma Rays

It’s not frequent, however certain avocados are exposed to radiation. This is done to comply with international trade regulations, depending on the originating region. 

If the avocado seed you’re using was exposed to gamma radiation, it will not sprout. This is because of the gamma-ray messes with the growth rate of the food

Reason 2: Growth Rate

Avocados are tenacious and might take months to mature. If you begin with hundreds of them, dozens will fail. It can take months for them to take hold. Furthermore, different kinds of avocados have different growth rates.  

“Hass” avocado pits are a little more difficult to start than the larger Florida kinds. But they will eventually start. So be patient during the entire process.
