One of the most commonly requested types of apple tree is the granny smith apple tree. The granny smith apple tree produces fruit that is tart and delicious. The apples from a granny smith apple tree are unique, in that they do not change in color from green. Most apples, once mature, will either turn red or yellow, and sometimes a combination of the two. It is harder to tell a mature granny smith apple from a younger one, in that they are both green.
The fruit produced by a granny smith apple tree is an all-purpose apple with green skin and firm crisp flesh. The fruit can be eaten straight off the tree, or cooked in a variety of fashions. The flesh of a granny smith apple will remain crisp for longer than many other breeds once the apple has been cut. The granny smith apple tree is believed to have originally come from the seed of a French crab apple.
Granny smith apple trees are not self-pollinating. This means that another type of apple tree is needed in order for the granny smith apple tree to produce fruit. Like most other apple trees, the pollinating tree used with a granny smith does not really matter that much. As long as the pollen is fertile, nearly any apple tree will be able to pollinate a granny smith apple tree and create delicious fruit.
Granny smith apple trees are hardy in zones six through eight, and require a good deal of sunlight. When pruned and cared for properly, a granny smith apple tree will grow for over fifty years. Granny smith apple trees do not require very much support, as they are typically able to support their own weight. In the semi-dwarf state, granny smith apple trees will grow to fourteen feet high.
How to Grow Apple Trees From Seed
Put the seeds in a container or zip lock bag. You can also add soil if you wish. Place the container or bag in your refrigerator for about 3 months.
If you chose to add soil you can moisten the soil after about 10 or 11 weeks. Keep a good watch on the bag and let fresh air in often. You should start to see leaves popping out of the soil in a few weeks if everything went right.
If you didn't choose to add soil you can try to plant the seeds directly into pots or in the ground. If you time it out you can let the seeds dry over the winter and put them into the refrigerator 3 months before the frost usually leaves. Cool weather seems to help apple seeds sprout as well.
