Answer: Your Dorsett Golden is a great choice for warm winter areas. The tree won't really begin to produce until it has been in the ground 3 years. Although it is considered self-fruitful, you'll get a heavier crop if you have a second variety of apple in your yard. Anna is a terrific variety to grow with your Dorsett. Apples on both Dorsett and Anna are considered medium sized fruit (about 3-4" in diameter).
Your apple tree shouldn't require fertilizer unless the growth is slow or off-color. If it needs a boost, you can broadcast a low-nitrogen fertilizer such as a 4-6-8 over the soil under the tree and scratch it into the soil.
Best wishes with your apple tree!
