Fruit trees for Austin


Fall / winter is the time to plant temperate fruit trees and we’ve got a great selection right now. We do a great deal of research to get varieties that will work well here in central Texas with little maintenance. So, let’s take a quick look at these fruit trees and cover a few basics you’ll need to know before planting.
First, a temperate fruit tree is a tree that will do fine outdoors, in the ground, in our weather conditions. The alternative would be tropical and sub-tropical fruit trees, like avocado, mango, and even citrus. These trees can be damaged or even killed by hard winter freezes, depending on the variety. The rule of thumb here in central Texas for temperate trees is the “P” fruits: peaches, pears, plums, persimmons, pomegranate, and phig (OK, so it’s really fig, but I needed it to work). We are also trying a few types of apples this year, although reports of their success seem to be mixed.
Second, be sure you have the room and conditions necessary to grow a fruit tree. While I encourage pruning trees to a size that is “reachable” for you, they will still need at least 8’-10’ of space away from a building or other trees and AT LEAST 5 hours of direct sun for good production. Full sun all day is fine for all these trees and will lead to better production.
Next, it’s time to choose a tree. Now, I have listed several types of fruit above, but all peaches (or pears, or plums, etc…) are not created equally. Many of the temperate fruits require a certain number of chill hours to produce fruit. Chill hours are the number of hours below 45 degrees between October and February. We strive to carry only low chill hour fruits, as we can often have very mild winters and hence, few chill hours. Even with the attempts we make, some winters are just too mild for good production. The Austin area averages about 700 chill hours a winter, but this can be extremely variable. All the good, independent garden centers in town do their research. Box stores likely do not.
Last, here are a few other tidbits of info you will need to know when choosing a fruit tree. All fruit trees will produce best if they have a cross-pollinator nearby, but some varieties require it. Peach, pomegranate, fig, persimmon, and some plums can be self-fruitful. Pears, apples, and most plums need another tree nearby to produce a good crop. This means room for not one, but two trees. Also, be sure to look at the characteristics of the specific variety you are looking at. Do you want a freestone or clingstone peach? Do you plan on cooking with your pears or eating them fresh? Do you prefer an astringent or non-astringent persimmon? One of our plant consultants will be glad to help you answer these questions and find the variety that is best for you.
So, plant a fruit tree or two this winter and be rewarded with a bumper crop of fresh fruit for years to follow.
