Topic for tonight

Woody plants

Fruit

Species/cultivars

Intentions

why plant woody plants for fruit
Why plant woody plants for fruit?

Fresh, jam, jelly, pies, sauce, juice, juice concentrate, dried fruit, frozen fruit, wine

To enjoy freshness and flavor of home-grown fruit

To control pesticides used on food consumed

To increase food security

To save on grocery bills

To grow varieties not available at the store

To ensure time outdoors

To lessen your carbon footprint

To produce homegrown gifts

To gain experience with different hobbies

general care of fruit trees shrubs
General care of fruit trees/shrubs
  • Planting
    • Dig hole 2 to 3 times the spread of the roots
    • Measure length of bottom roots and top roots
    • DO NOT bury the graft union
    • Prune back excessively long or broken roots before planting.
    • Back fill soil into hole; tamp soil and water with bucket or hose to remove air pockets

Fruit thinning

Overall:

1 apple per 40-50 leaves

1 fruit per spur

Stages:

1st- ~June 20th or when fruit is ½” diameter

2nd- after June drop to 4-8” apart
