Fruit Tree Windbreaks
• Primary function is wind protection – Tree spacing is much closer than normal
(orchard)
• Fruit yield will be reduced dramatically once the plants are mature, if irrigation and nutrients are not provided along with a pruning program
• May require thinning in about 5-10 years depending on species
![Page 3: Fruit Trees: Income Generating Plant Materials for Windbreaks, Vegetative Barriers, & Hedgerows](https://reader035.fdocuments.net/reader035/viewer/2022062803/56814883550346895db595b8/html5/thumbnails/3.jpg)
Land Preparation
• If planting on new or overgrown land clear unwanted vegetation taking care not to remove the top soil– If using a bulldozer do not scrape the soil– Steeply sloping land should not be stripped
of plant cover due to susceptibility to erosion
• Do not operate any machinery on wet soil because it will cause compaction affecting plant growth and development

Planting & Care
• Minimum:– Dig a hole the same depth and twice as
wide as the root ball– You want the crown (point where root &
stem meet) level with the ground surface
• Keep soil and mulch away from the base of the plant to avoid rot
![Page 5: Fruit Trees: Income Generating Plant Materials for Windbreaks, Vegetative Barriers, & Hedgerows](https://reader035.fdocuments.net/reader035/viewer/2022062803/56814883550346895db595b8/html5/thumbnails/5.jpg)
Planting & Care
• Break up any of the roots that are circling the root ball “pot bound roots”
• Inspect roots for “j”root make sure tap root is straight
• “Its better to plant a $1 plant in a $10 hole than it is to plant $10 plant in a $1 hole”

Mulch
• Mulch Your Plants– Weed barrier– Slow release nutrients– Conserves water– Protects your plants from bush cutters
• Bush cutters– Often damages desired plants – Physically harms plants – Bush cutter disease
(careless cuts girdle tree) kills huge numbers of trees on Guam.

Common Causes of Plant Death
• Planted too deep• Mulched too deep• Over watering or under watered• Bush cutter damage• Mulch or soil up against plant base
(stem)

& other parts of skin– Sap burn on fruits
