Q.Can I grow Hass avocados in Miami?
Can I start a healthy avocado tree from the seed of a Hass avocado I bought in the supermarket here in south Florida? or must I plant a Florida avocado?

Sure! You can plant a pit from a store bought avocado, but they don't normally produce a very tasty fruit from seed. They must be grafted from a variety known to fruit well. Your seed-planted tree will still flourish, but it may not yield anything edible or tasty.
It is best to graft a new top onto your seedling's rootstock, or to purchase a tree that has already been through this procedure. This will ensure that you get a good fruit and that the tree is robust and healthy. They usually fruit within just a couple of years from graft, versus a seed which can take many years to fruit, if it does at all.
