Where We Live:  High elevation at the edge of Mountains and

Plains.  Harsh climates with: 

High winds.  Drought periods and watering restrictions.

 Intense solar radiation.  Dry winters.

 USDA Plant Hardiness Zone 4

Why you want to plant a tree?  Shade

Finding the right spot  Allow room for full growth at maturity.

 Follow soils and engineering reports for your

property to protect your foundation.  Avoid conflicts with future uses such as utilities, lawn area, and blocking of views.  Remember the future trunk flare and its relationship to concrete surfaces and fences.

Soils- Mother Earth  Heavy clays are tough on trees: 

Shallow rooting and conflicts with turf.  Do not allow for good soil atmospheres with good oxygen content.  Prone to uprooting in high winds and heavy snow loads.  Prone to compaction with heavy use.

Soil Amendments  Incorporate organic material 12-18 inches

deep and well beyond the drip line.  Use well aged compost.  Do not use horse manure- too hot with salts!  3 cubic yards per 1,000 square feet.

Buying Trees  Look for: 

A central leader or main trunk.  Root Collar at or slightly above ground level of the root ball.  Avoid: 

Trees with multiple stems and no dominant leader.  Plants with circling roots.

Remember:  The fullest looking tree is not necessarily the

best tree.  A tree with a strong central leader will tolerate wind and snow.

Best Trees for our area:  Conifers: 

Ponderosa Pine, Austrian Pine, White Fir, Douglas-fir.

 Deciduous: 

Oaks, Honey locusts, Kentucky Coffee Tree, Hackberry, Linden, Norway Maple.

 Refer to “Recommended Trees For Colorado

Front Range Communities” and “Trees and Shrubs for Mountain Areas”

Planting Tips:  Dig wide planting holes- not deep.

 Do not dig deeper than intended planting

depth so tree will not settle.  Plant 2-4 inches above surrounding grade.  Mulch well beyond drip line with 2-3 inches of mulch.  Water deeply and infrequently.

Dig Wide! Not Deep.

Remove!  All twine, rope and wire from around the tree.  Remove any wire baskets on the upper 2/3rd

of the root ball after it is placed in the planting hole.  Remove all burlap from around or on top of the root ball.

Staking and guying  Stake low on the tree.

 Remove after the first year. Do not leave

staking on any tree for more than two years.  Use webbing or old carpet strips.  Do not place wire or string around the trunk.  Do not use any type of hose.

Watering Reminder:  Deep, infrequent watering is best for good

root development and prevention of drought stress.  Check regularly with soil probe.  Turf watering and tree watering are not the same thing!  Allow periodic drying of the root zone to allow oxygen back into the soil.

Tree Watering with drip systems  Provide emitters to areas outside the root

ball.  Check regularly to make sure they are working.  Make sure they are all on a separate zone so it can provide “DEEP, INFREQUENT watering”.  Frequent, shallow watering promotes poor root development and does not promote drought tolerance.

Mulching  Start at 0’ depth at the trunk or root collar.  2-3” of mulch is enough.

 Do not use more than 4”.

 Do not put mulch volcanoes around the tree.

Mulches

Weed Barriers/Fabrics  Please, do not use them!

 No soil is ever built at the mulch/soil interface.  Do not allow for good air exchange.

Pruning  Learn to make proper pruning cuts.

 Look for the branch collar and branch bark

ridge.  Train trees when young to avoid large cuts as the tree matures.  Remove dead, dying, diseased and deformed branches.

Branch Collar Pruning

Different Collar Locations

Monitor regularly for:  Watering

 Over watering  Insect pests: 

Aphids and spider mites  Scales  Defoliators  Diseases like fire blight

Native Pine Care  Ponderosa Pines

 Northern most extent of the “Black Forest”

 On the edge of the “Great American Desert”  Ages may range from 30 to 150 years old.

Tallyns Pines are:  Shallow rooted due to heavy clay soils.  Easily impacted by construction and

landscaping activities.  Subject to overwatering!

Root Zones of Our Pines

Shallow roots in heavy clay soils.

Pines in Trouble  Overwatering: 

Yellowing branches from the bottom upward.  Off color needles, yellowish green.

 Root loss: 

Top dieback.  Thinning foliage throughout tree.  Attack by Ips beetles.

 Raised grade: 

Similar to overwatering symptoms.

Poor Drainage  Grading that allows water from irrigation and

storm run off to slow down and flood trees.  Water from adjacent neighbors flooding into your yard.  Sump pump discharges not drained away from trees.

Raised grade

Bark Beetles  Ips Engraver Beetles 

Main threat in Tallyns Reach.  Mountain Pine Beetles are rare in the area.

The Beatles

The Bark Beetles

Ips killed pines due to construction

Ips Love Weakened Trees!!!  Excavation

 Trenching for: 

Utilities  Irrigation

 Transplanting

 Lightning damage  Drought

Preventive Spraying for Ips  Must specify to tree spraying company that

you want your tree sprayed for Ips.  NOT Mountain Pine Beetles (MPB).  If sprayed for MPB, then only trunk is sprayed.  Ips attack the top, branches and trunk!
