Granny Smith Apple Tree Planting Guide

To ensure that you get the best possible results, it is essential to follow certain preparation tips and plant the tree properly. Let’s see how to plant a Granny Smith apple tree!

  1. Granny Smith can thrive in various soil types. However, to improve macronutrient and micronutrient concentrations, add organic material such as compost to the soil. Stir 2-3 inches of the compost into the soil at a depth of between 18 and 20 inches.
  2. Now, it’s time to choose the right sapling. For ideal results, you should choose a seedling that is around 12 months old and 6 feet tall.
  3. Once you’ve brought the sapling home, keep it in a cool area. Before you start planting, you should soak the sapling’s root ball in water for half an hour, to help soften the roots.
  4. While the tree is soaking, dig a hole that is slightly larger than the sapling’s root ball.
  5. Place the tree in the hole and fill the hole with the soil.

Granny Smith Apple Tree Care

Initially, the Granny Smith apple tree requires regular watering and pruning until the tree is established. Once a year, either by the end of the winter or the beginning of spring, you should trim the tree to allow the airflow between branches.

You should also fertilize the tree three times during the growing season. The first fertilization should be in the early spring before flowering. Make the second application about 30 days later and the final application by the end of June, around 30 days after the previous application.

Finally, you should spray the apple tree properly to ensure the best fruiting. Winter is the best time to remove garden debris and spray the tree with dormant oil, while spring is good for spraying against mites, mildew, and fire blight.

On the other hand, fall is an ideal time to spray against microscopic critters if they are a problem in your area.

Granny Smith Apple Tree Pruning

One of the best tips to follow when it comes to pruning your apple tree is to do it in the late winter. That way, the cuts will heal faster during the spring.

Granny Smith Apple Tree Common Problems

The most common problem with apple trees is fire blight, caused by fire blight bacteria. The weather can play a significant role in spreading the disease since rain and humidity can cause the bacteria to spread rapidly.

In that case, you should discontinue irrigation and reduce the amount of moisture on the foliage if you are using any.
