Tree and Landscape Seminar July 15th, 2014 Tyler Balderson BMCA Bartlett Tree Experts Top 5 trees to plant and where What to plant near the water How to spot weak trees before they fall Best Practices for caring for trees Does topping trees make any sense? New Critical Area rules What to do with Invasive Trees When should you trim trees Should they overhang the house? What to do to minimize possible damage from hurricane winds and rain Born in Montgomery County, MD Raised on a tree nursery, My father Andy Balderson is a Landscape Architect B.S. Virginia Tech 1998, Board Certified Master Arborist, Maryland Licensed Tree Expert, Certified Tree Care Safety Professional. Reside in Odenton MD with wife and 3 kids Bartlett is 107 years old, Serving Anne Arundel for over 60 years. Every property is unique. Every property has specific needs based upon the environment in which the landscape lives. My presentation will discuss general ideas and practices, however, just like people every site is different and should be treated as such. Hydrology Aspect Soil Human/Engineering (Controlled/Uncontrolled) Vegetation (shade trees, mid-story, understory, turf). Management/Maintenance Everything! Plants have specific needs based upon water, sunlight, soils, slope. Right tree right spot Avoid monocultures Native? (native to where, what is the definiton of native?) Native: This includes plants that have developed, occur naturally, or existed for many years in an area (Wikipedia) How much sunlight is there now, and in the future? What is the growth potential of the tree based upon the location in which its planted. Maximum size at maturity Future plans (renovation, driveway, septic, slope considerations) Maintenance needs of the tree/landscape. - Hollies - River Birch - Beech - Bald Cypress - Willow Oak (other various species) - Sweet Gum - Black Gum - Swamp White Oak - Redbud - Sweetbay Magnolia - Dogwood - Serviceberry - Bayberry - Winterberry - Native Hydrangea - Itea - Fothergilla - Rhus - Viburnum - Grasses, grasses, grasses - Tiarella - Solidago - Rudbeckia - Hibiscus - Echinacea Trees are similar to people, we can’t just take care of them when they get old! Many of the problems can be solved with proper care while trees are young, young trees should be pruned annually, monitored for insects/diseases and protected from damages that may cause issues in the future Older trees typically require pruning every 2-3 years, usually just deadwood. Regular maintenance inspections for insects and disease, consideration fo cables/lightning protection on specimen trees. Topping is perhaps the most harmful tree pruning practice known. Yet despite more than 25 years of literature and seminars explaining its harmful effects, topping remains a common practice. Crown reduction can be done, but goals need to be clearly defined and view is not a goal for the plant! Have a defined goal of what you are trying to achieve (structure, shape, thinning 25% max, clearance, deadwood) In general prune flowering plants soon after they flower. Crepemyrtles (April as they flower on new growth). Pruning is like surgery, more is not necessarily better! Winter is a great time to prune as structure can be easier to identify. In general the critical area is defined as the 1000 foot area surrounding bodies of water. Buffer is defined as 100 feet from bodies of water but can extend further based upon slopes. Structures and impervious surfaces fall under the critical area. (1000 feet) Vegetation falls under the buffer area (100+ feet) and or 5,000 square feet of disturbance within the critical area Contact the county with any questions regarding critical area or buffers, they are here to help! Doing nothing within the buffer is not considered management! The county encourages management in the buffer to prevent invasive species, improve the buffer and prevent future damage to the buffer. Identification, treatment and mitigation are all part of an invasive species plan. This is a long term management plan, not something that can be fixed immediately. Green briar/mulitflora rose English Ivy (is it a bad thing?) Mile a minute vine Grape vine Kutzu Japanese knotweed Poison ivy Habitat for ticks/mosquitoes Have an arborist inspect your property A good arborist can identify the problem before the homeowner does. Typically when a homeowner calls, its to late! Set a management plan, small amounts of work can add up to lots of preventative work over the course of months and years. Heaving ground, the tree is uprooting! Any cracks in the ground, base, or trunk of the tree Discoloration, staining, black mold under the canopy of the tree. Hollow trees, sounds like a drum when tapped with a mallet. Poor tree structure Exposed trees, or changes in the environment around the trees (recent clearing) Tree species and hydrology Deer……. www.treesaregood.com http://www.invasivespeciesinfo.gov/plan ts/main.shtml http://extension.umd.edu/ http://www.aacounty.org/ www.bartlett.com www.campionhruby.com www.exteriorimage.com www.walnuthill.com www.ciminellislandscape.com www.drumloyka.com Questions?
