Permaculture Plants: Apple Trees

This is the first of hopefully many entries on specific plants to be used in a Permaculture System.  I attempted to document every aspect of a plant that would be useful, but I am sure there are things I missed.  However, this should be a fairly holistic overview.

Heirloom Apples

http://nourishnetwork.presscdn.com/files/2010/10/heirloom-apples-frames.jpg

Common Name: Apple
Scientific Name: Malus domestica or pumila
Family: Rosaceae

Description: Hardly needs description. Moderate sized tree to small dwarf trees.

History: Originated in Western Asia (Turkey?). Likely the first tree to be cultivated. First brought to the U.S. in the 17th Century.

Trivia: China is the main producer of apples. The U.S. is second.

Size: Depends on root stock

• Own root, Standard: 20-26’ (6-8m) high x 20’ (6m) wide → tall, not for fresh eating apples which should be picked from the tree, but can be used for juice/cider apples which can be picked up off the ground
• Semi-Dwarf: 13-16’ (4-5m) high and wide
• Dwarf: 8-13’ (2.5-4m) high x 12’ (3.5m) wide

Roots:  Flat, mostly shallow roots
Growth Rate: Medium

GROWING CONDITIONS FOR THIS PLANT

Light: Full Sun preferred
Shade: Tolerates mild shade
Moisture: Medium
pH: 6.1-7.0

Special Considerations for Growing:

• Tolerant of most garden conditions
• Not tolerate to Juglone, a natural growth inhibitor produced by members of the Walnut Family: Hickory, Pecan, Walnut, Wingnut

Propagation: Typically by grafting.  Seeds are not true to type - meaning they produce apple trees that produce apples that rarely taste anything close to the parent stock... often they do not have a good fresh eating flavor, but could be used for hard cider.

Maintenance:

• Pruning annually to every 2-3 yrs
• Needs nitrogen and potassium to sustain cropping

Disease/Pests:
Numerous diseases including various types of Apple Scab, Blotch, Rot, Canker, Mildew, Rust, Pit, Scald, Mottle, Blight, and pests including Nematodes, Codling Moth, Aphids, Bird, to name just a few.

Concerns:
Seeds and leaves are poisonous – contain a precursor to cyanide (large amounts need to be eaten for this to be toxic).
