New Jersey Stone Fruit Production
1999 Tree Fruit Survey
• Peaches 7,656 Acres• Nectarines 694 Acres• Cherries 65 Acres
New Jersey“the Garden State”
• 9 million people
• 8,000 farms
• 400 fruit farms
• 7000 A peaches
• 1000 A nectarines
• 2500 A apples
NJ is the Northern Most Commercial Peach Production
State
Most Important Issues
• Flower Bud Hardiness
• Tree Hardiness
• Cytospora Canker
• Peach Borers
• San Jose Scale
Back to Basics
Location-only best orchard sites• Frost Free site-know past weather
history• North Facing-delay bloom• Well drained fertile soils
N
More Basics
Plan two years ahead• Soil Tests• Adjust pH and nutrients• Nematode assays • Add soil organic matter• Control perennial weeds• Order Trees
Type of Tree To Order
•Smaller Caliper•Weak tree•Low Buds
Pay Attention to Proper Establishment
• Correct pH and Correct pH and NutrientsNutrients
• Establish Raised Establish Raised bedsbeds
• Establish sod middles Establish sod middles and herbicide strips and herbicide strips the fall beforethe fall before
Turf Establishment
• Rutgers Fact Sheet FS319 on Orchard Rutgers Fact Sheet FS319 on Orchard Turf Establishment Turf Establishment www.rce.rutgers.edu/pubs/pdfs/fs319.pdf
• Plant in the fall before establishmentPlant in the fall before establishment
• Turf type tall fescue cultivars have Turf type tall fescue cultivars have worked best in NJworked best in NJ
• Prevent Erosion and have IPM benefitsPrevent Erosion and have IPM benefits

Soil Preparation
• Subsoil Prior to planting
• Clay Pot Effect From Auger-(fall)
• Break sides before planting
Planting Depth& Lime
• Correct Planting Depth• Leave graft union 2”
above• Two pounds of High
Calcium Lime in backfill

Cultivar Selection
• Select only bud hardy cultivars-most California cultivars are not hardy enough
• Bud vs. wood hardiness
• Unique Cultivars white flesh-non melting flesh
Donut Peaches

Peentu Types
• Saturn
• Galaxy
• Jupiter
• Numerous NJ Selections
Avoid Winter Injury
• South West Injury
• Peach Borers

Cytospora Canker
•Most Serious Problem in NJ and the North East•Prune at bud-break in April if possible•Paint Pruning cuts on scaffolds•Use tree paint with benomyl
Peach Planting Systems
Higher Density 10 x 18
Y or V
Central Leader
Standard Northern New Jersey Production System
• Open vase training• 20 X 20 or 25 feet• Dormant and Summer
Pruning• Herbicide Strip• Sod Middles• Trickle or Drip
Maintain tree height at 8 feet
Pencil thick fruiting shoots
Peach Fertility
• Soil and tissue tests• Split applications of nitrogen• 1st app. In a complete fertilizer 3-4 weeks
prior to bud break to supply 1/2 total seasonal N requirement
• 2nd app. at shuck split• If frozen out eliminate 2nd app.• Do not over-apply Nitrogen• Do not apply N After June 1
Peach Thinning
• Large Size is Essential
• Thin Early-consider bloom thinning
• Wiffle bat, toilet brush, fan belt on broom handle
Sweet Cherry
•Dwarfing Rootstocks-Gisela
Concerns-
1. Cracking-rain-covers
2. Birds-netting
3. Bacterial Canker

Bacterial Canker
• Bordeaux sprays
• Summer prune only
• Stub prune
• Resistant Cultivars
