I've corresponded with Dr. Sauls, who is quoted. I asked him for his opinion on the article. Here are his comments:
"Well, I knew the article was coming, but had not seen it. I was a bit
curious to know what I was quoted for saying, as well as what Ms. Thomas
had to say, and what the writer stated without quotes to any source. To
say the least, I am disappointed.
First, I did not recommend Helen's skills; I don't know her, nor have I
ever communicated with her. The only information I had about her was a
short e-mail from the writer, Kendall Anderson.
To correct the record, I did not state "the lack of humidity make
oranges an unlikely success", as humidity has relatively little to do
with it. I don't necessarily agree with some of Ms. Thomas's
comments--for example, "shelter from hot Texas summers" suggests that
the summers in the Dallas area are substantially hotter than in the
Lower Rio Grande Valley, or in Laredo or other areas of the state.
Another disagreement is with her quote that "humidity and balanced
fertilizer are key"--I seriously doubt that the humidity in Dallas is
consistently lower than what is normal in the Valley or upriver to
Zapata, Laredo and Carrizo Springs--where a lot of citrus trees are
grown.
The writer indicated that Ms. Thomas uses ladybugs to eat..."aphids and
thrips that kill trees by sucking the juice from the leaves"--neither
aphids nor thrips nor any other insect kills citrus trees.
It is apparent that all of the trees were grown from seed, as budded
trees produce in the second year from planting, whereas seedlings may
not produce for anywhere from a few years to 10-15 years.
Obviously, the keys to success in north Texas are a sufficient budget
to afford the large containers, some means to move them, and the
greenhouse into which they will be moved for winter cold protection.
Sunlight is critical, as citrus does best in full sun (Ms. Thomas
apparently has hers in the shade of overhanging oaks et cetera). "
