About three years ago I bought 2 apple trees, one a Dorsett Golden and the other I believe was an Anna tree. The past two years the Dorsett has given apples, last year about 15, this year about 50 or so. The other tree, which I am not sure what it is because the tag fell off but I believe to be Anna, has yet to produce. The "Anna" tree blooms about a month or so after the Dorsett. I'm wondering if the unknown tree is an Anna or do you know of any tree that blossoms about a month or so after Dorsett? I was wondering if its worth to hang on to the tree or replace it? The tree is growing and is actually a little bit bigger than the Dorsett. Thanks for any help.
Unfortunately, apples are very challenging, almost impossible, to cultivate successfully in Texas. They require more chilling and deeper soils than we have. They also have very specific requirements for cross-pollination with other apple cultivars. Consequently, your 'Anna', or whichever cultivar it might be, will most likely never produce fruit. On the off-chance that it is not an 'Anna' and chilling is not the issue, you might consider planting a crab apple. Crab apples cross-pollinate most apple cultivars.
