As Cooperative Extension educators,

What is the best dwarfing apple rootstock for my area?

The best dwarfing rootstock for your area depends on your location, soil type, and what apple production system you wish to utilize.

Your apple production system determines whether you need a rootstock which will result in a free-standing tree and what size that tree needs to be, or whether the rootstock needs to be more dwarfing and will result …

What is Nectria canker, and how do I identify and manage the disease on apple trees?

Nectria canker is a fungus disease caused by Nectria galligena. It is occasionally found on apple nursery stock shipped into the eastern United States. The economic effects of the disease in the eastern United States are minor. The fungus grows deep into the wood and kills new wound callus as it develops. This annual killing of successive layers of callus results in perennial, target-like, zonate cankers. Eventually the cankers girdle the tree, resulting in a dieback of infected limbs …

In mounding, the plant is cut off close to the ground. As the new shoots emerge from the mother plant, they are partially covered with soil or well-decomposed sawdust. The sawdust is renewed periodically during the growing season to prevent the base of the shoot from exposure to …
