Fruit Part 1: Trees

This was initially one very long post, but I decided to break it up into trees and vines/bushes.

I'm not just going to limit my gardening to the 5' x 5' box, I'm also going to try and grow fruit. I could try to grow these from seeds, but that will probably fail, so for all the fruit trees and bushes I bought young varieties.

There are a few issues with regards to fruit that I had to figure out. Plant hardiness zones were the primary thing, but they were pretty easy to figure out (see here). I'm in zone 8b, the same, coincidentally, as my parents in Central Florida. This is a bigger issue for the fruit trees than the veggies, but if you look on the back of seed packets or tree tags they will say which zone the plants will thrive in.

A little more complicated were the "chill hours" for my area of Texas. What are chill hours? According to Texas A&M:

"hours of winter temperatures between 32° to 45° F to break dormancy and induce normal bloom and vegetative growth. If varieties are chosen that have a chilling requirement that is too low, there is a greater probability that they will bloom early and be more subject to frost. If the chilling requirement is too high, they may be very slow to break dormancy and abort fruit."

I found a map on the Texas A&M University Extension Service website which was really helpful (and not just for this part). The relevant image is here:

Travis County (where we live) is in the 700 hour zone, but I think that is a little misleading because that includes some of the Hill Country, which can get very very cold, as well as Austin proper, which will stay warmer than the surrounding areas just because it is a big city. Also, most of the posts about gardening in Austin I have read usually complain that they don't get enough chill hours to grow certain fruits. Bearing this in mind, I figure that we probably get around 500-600 actual chill hours on the eastside... Issue 1 "solved."

The second issue was the soil. It's nice because I don't have to go through the whole measuring and mixing process as for the square foot garden because the trees and bushes are going to go in the yard (except strawberries, which will go in the garden). However that limits me to whichever trees will thrive in Austin's alkaline soil. So, alkaline soil and around 500-600 chill hours.

Thirdly, the pollination issue. Some trees require a second to pollinate it. If there is no pollinator present, you'll tend to get blossoms but no fruit. Because I have limited space, I would rather have 2 self-pollinators rather than 2 of the same type who must pollinate each other. So, alkaline soil, 500-600 chill hours, and self-pollinating. One caveat...I spoke to my backyard neighbor who informed me that there are some fruit trees in adjacent lots. I'll pay attention this summer and perhaps I can get a tree that requires pollination in next winter.

So these were the criteria I was working with. I also found a really awesome page on the Extension Service website about growing fruit trees, which work well, which varieties are best, and so on here. With a few exceptions, I bought most of my trees from Willis Orchards and planted them.

For the first tree, I chose Apricot. Apricot grows very well in Texas provided, once again, you get the chilling hours right. I chose the "Royal" variety, which, according to the Extension Office, it is "one of the most consistent croppers in the Hill Country." It is also self-pollinating, and I put it between the pecan tree and the back fence. However, I will need to be watchful that Riley doesn't get into the fruit. She has been known to eat tomatoes off the vines...

Apricot tree, I dug out a large hole and backfilled with some of the leftover compost

For the second tree, I went with a peach, the "La Feliciana." This one I bought at Home Depot. Usually this is not a good idea because the big box stores tend to sell whatever the hell they can probably get the cheapest, regardless of whether or not its appropriate for the climate in that particular area. In this case, however, the La Feliciana is a good match with its chilling hours (about 550) for our yard. I planted it in the backyard, between our back boundary and the apricot tree. I dug out the ground and added one of my spare bags of compost, then planted the tree (right now it is about 5 feet tall):


Thirdly, I chose a pomegranate tree, the "Wonderful" variety. Like apricot and peach, pomegranate trees are exceptionally well suited to Austin. I've got a good spot for this one in the front yard. It grows up to 18 feet tall which, if mine actually survives, will pretty much dominate the front yard. It will be a nice problem to have...

now its just a little guy...

I also got a flyer from Austin tree folks, a local organization that gives away free trees, provided you plant them close to the street so they will help mitigate the urban "heat island" effect. They gave a choice of trees, but the only one that was fruit bearing was a "Mexican Plum." I'm supposed to get it dropped off in a few weeks, so when I do I'll post about it.

Just a note here: I really, really wanted to try to grow a cherry tree. I love cherries and remember having a cherry tree in my backyard in the 'burg growing up. I did a bit of research online and found that a "Brooks Cherry Tree" would fit pretty well in my chilling requirements. However there are other issues- Cherry Trees need well drained, mildly acidic soil and are sensitive to excessive sun. I could try to fortify the soil, and I did have a spot where the sun wouldn't be too intense, but trying to do all this twice (I'd need another cherry tree to pollinate) would probably make my margin of error too slim. Also, one of my guiding principles of the yard is minimum maintenance. I realize this is kind of an oxymoron with having a garden, but cherry trees just seem to add a lot of work with a slim chance of paying off.
