Avocado wont' survive in Austin,TX without a greenhouse over it. I'd recommend the all female varieties of asparagus.

Only the most tropical areas in CA can grow the good avacadoes. Even in the south valley of Texas, you are limited to the inferior varieties. Austin isn't even close to suitable. Try figs, peaches, pears, or even apples. They are much better for Austin.

Yeah,
Hate to be a neah sayer but Avacoado may not be the best choice. I Know some people who have grown the Front variety that I think originated in San Antonio in a green house and they were disapointed with the quality. Hass may be the best choice for you if you just want to have an Av. tree. Just know that they have zero tolerance to cold, I mean none.

Mpp:

I wouldn't even touch the avocado issue, which I wouldn't try to grow in Austin on a bet. But you can grow asparagus if you have deep, rich soil. I have had great success with the New Jersey developed variety Jersey Knight, though there are some California varieties that might do better in Austin.

Mr. Texas meant to say all-male rather than all-female asparagus. When your find a female in the patch, as indicated by seed berries, take it out.

Asparagus is booming right now in Northern Virginia, and we are cutting every 3 days.

Last year I paid while working in San Antonio TX, I took a drive to Devine, about 30 miles south of San Antonio. There's a man that collected avocados that grew in southern texas and currently grows them in his yard. The trees are over 30 ft. The one year temperatures dropped to 14F and they did have winter damage and were defoliated, the following year they were fine and did set a full crop.
If you go down to San Antonio go to Fenwick nursery and ask them about their avocados. You are north of that area so, good luck.
