Avocado Searches.

I'm getting a lot of hits from people with avocado (Persea americana) questions. Here's some of what I've seen so far, including what little information I can provide, being a person with lots of questions about Houston avocado growing, myself.

Hass Avocado Hardiness Zone
According to Floridata, the Hass avocado is a Guatemalan variety, and "Guatemalan types are intermediate, hardy to 24 F (-5 C) or so." That would put it roughly in USDA zone 9b. To find your USDA hardiness zone by your zip code, click here.

To give you an idea of the ideal conditions are for this Avocado, this variety is frequently grown in California. Many of the ones I buy from my local grocer are grown in Michoacan, Mexico.

Young and/or unestablished Haas avocado trees need to be sheltered well during freezing temperatures. See this page at Purdue University for a chart that includes cold hardiness information for various Avocado "races" Other avocados, usually Mexican varieties, can be hardy to zone 8.

Hello and welcome. Here are all of my avocado posts so far.

Also, check to see what Google BlogSearch has to offer. Avocado growing was the most useful query of the several I tried.

Growing an avocado tree fantastic
"Fantastic" Avocado
Yes, avocados are fantastic.

Oh, you meant the cultivar. :)

Urban Harvest lists this one as particularly cold hardy, and also particularly tasty! Unfortunately, I can't seem to find anything else on the internet about this variety. It is not listed in my copy of the Western Garden Book. However, as it is a Mexican variety, as are Wilma and Opal, it would probably have plenty in common with others from the same part of the world.

Hass Avocado blooming season

According to my copy of the Western Garden book, the fruiting season is April-October. This can vary, of course, depending on the exact climate conditions in one's region.

This Purdue University page states that Guatemalan varieties of avocado such as Hass bloom from March-April, with fruit maturing from September-January. The Purdue page is worth looking at, because it lists other differences among the three "horticultural races" of avocado.

Hass Avocado growing Texas
It's not easy, with the blasts of arctic air we get down here during the winter. See my link above to my posts on Avocados. I also highly recommend seeking out locally published gardening books for your region of Texas.

Nursery Houston Avocado trees

I don't know of any particular nurseries myself. However, if I wanted to find out, I would call or go to the nearest good local nursery available (I mean the mom-and-pop type places where the people working there know everything about plants and love to talk about them all day long) and ask. If they don't have them, they will probably be willing to point you in the right direction. Also, watch local fruit tree sales.

This website lists current grower inventories of many trees, including the Avocado. At the time of this post, they list Brazos Citrus nursery In West Colombia, TX as a grower of three avocado varieties. They are a wholesale seller only. Click here for a list of retail nurseries that sell their products.

In Year Round Vegetables, Fruits, and Flowers for Metro Houston, Dr. Bob Randall recommends purchasing trees from nurseries that stock plants from Treesearch Farms.
