Organic Lawn Care Defined

Thursday, September 2nd, 2010

Considering New York’s ban on lawn fertilizers and tightening restrictions in other states it seems inevitable that your lawn care will evolve as pesticide applications become more and more limited.

But what is organic lawn care?

The term is more or less unregulated so it is difficult to make an apples to apples comparison. However, there are two main approaches.

Organic – Organic lawn care is a multi year process that takes patience and commitment. Weed control involves hand picking and application of clove oil or citric acid. Insect control may include microbial products and specially formulated insecticidal soap.

Cultural methods with compost and topdressing improve soil and overseeding and appropriate watering provide a good ratio of grass to choke out broadleaf weeds.

Your lawn will respond even better if the lawn species is native to your area and the grass is kept at 2 to 3 inches long with mowers blades sharp and well maintained.

Hybrid (IPM) – A hybrid approach mixes in the above practices but may also include spot spraying of weeds and the use of “bridge” fertilizers (containing urea) to keep the lawn green until organic processes start to take root.

Because a true organic approach is likely a three year process, you may find a hybrid approach a good mix of environmental awareness, results and lower cost.  It may not take as many visits from a lawn care company.

Picking the Right Organic Lawn Service

Before you decide on a lawn service, it’s important to know what they mean by organic. It’s also important to know what you mean.

If you want your lawn to quickly green up or don’t want to spend too much dough, then a hybrid or traditional non-organic program may be the right choice.  If you are a true believer who is patient and will enjoy the natural process of your lawn improving, then a fully organic program is probably exactly what you want.

Large national chains have about 2% of their clients on an organic program.  There may be a local lawn service with a deeper knowledge of organic practices in your area, so look around and get quotes.

Condolences to the family of Adam Mackintosh

Monday, August 30th, 2010

David Merriman and the entire ArborScape family wish to express our condolences to the family of Adam Mackintosh, the tree trimmer who died last Thursday in Littleton, CO. According to news reports, Adam was thrown from the cherry picker he was using and fell 30 feet. The arm of the picker appears to have broken and collapsed while Adam was perched in the bucket.

It’s a sobering reminder that there is no such thing as a routine tree trimming job. We send our thoughts and prayers to Adam’s wife and children.  Rest in peace, Adam.

When is the best time for a sprinkler blow out?

Thursday, August 12th, 2010

A sprinkler blowout is best done in October in the northern climate of the United States.  When to turn off your sprinkler is a delicate balance of good timing and luck.  Do it too early and your lawn may lose precious water it needs to prepare for the winter. Wait too late and sprinkler repairs may become necessary if  a hard freeze occurs

Moving into a new home, or having a new sprinkler installation can create uncertainty about how to handle the routine sprinkler maintenance at the end of the sprinkler season. You may want to call a sprinkler repair company of good reputation, at least the first time.  Most will do a free evaluation.  We recommend contacting ServiceMagic to get up to four quotes for a sprinkler blowout.

Sprinkler blowouts usually cost around $10 per zone with discounts available for larger systems.  We’ve charged around $55 when providing the service in the past.  An air compressor is used, typically at about 80 psi (pounds per square inch) or lower. Higher and you could blow off the heads.  A good irrigation tech will know the recommended psi whether your brand of sprinkler system is Rainbird, Toro, Hunter or another brand.

So what is the cost of not properly blowing out your sprinkler? We once talked to a woman who had an extra $800 on her monthly water bill because there was a leak in the system.  Sprinkler system repairs can include replacing blown out pumps, defective backflow preventers and cracks.  It’s easy to rack up hundreds of dollars in repair bills.  At worst, a hard freeze can cause a sprinkler system re-installation.  A sprinkler system for a 5000 sq. foot lawn can cost $3500 or more to replace. Makes a $50 blowout seem cheap and easy to do doesn’t it?

Thousand Canker Spotted in Tennessee, Missouri

Thursday, August 12th, 2010

Walnut trees are dying off right and left throughout the Denver area and along the Front Range due to thousand canker disease.  I was talking on the phone with the city of Boulder, Colorado forestry office and the eastward expansion of the disease seems to be going more quickly than first thought. Missouri and Tennessee have seen 1000 canker infected walnuts this season. Given the thick stands of walnuts in the central and southern Appalachian Mountains regions, this is nothing but a discouraging sign.

Black walnuts are a common ornamental tree in Denver. Yes, it sucks if it dies but ultimately its replaceable.  In certain parts of the South, losing walnuts means losing jobs and disrupting entire communities. Walnut wood is a prime material for the woodworking and furniture manufacturing trade throughout the South. If thousand canker moves aggressively, it could wipe out millions of acres of walnuts in Tennessee and North Carolina disrupting tourism as well.

Boulder is taking strides to have qualified tree contractors remove infected walnuts and deposit them at a holding facility off of Arapahoe Rd.  As late as spring 2009, there was a strategy by a consortium of  Colorado agencies to keep 1000 canker contained  west of I-25. Obviously, new ideas will need to be developed but it could take a miracle to avoid a dutch elm like epidemic of dying walnuts.

Plant Health Care (PHC) Glossary

Tuesday, June 8th, 2010

Today we published the first of what will be many updates to a tree trimming and tree care glossary of terms. The arborist is in love with accuracy and he may use the most accurate and obscure arboricultural words in diagnosing your tree.  That may leave you in doubt.  You want a tree that looks good and is healthy on the inside, wittout knowing the entire biological process. At the same we thought it would be helpful to start a glossary,  eventually one that is searchable with definitions that make sense to any tree owner.

Our editorial assistant Amanda helped in putting this glossary together. We tried to define these terms in the barest of language. Please let us know if any questions.

Ash Tree Trimming – Understanding the Process

Wednesday, May 26th, 2010

We have an overview on ash tree care but one thing you should know is that ash trees very commonly break from snow weight.  Thus ash tree trimming can be quite extensive and you will lose some shade in the short term.  However over the course of the growing season,  you’ll find that the tree grows into its new look.  Ash trees branch out again quickly,  so the newly pruned ash will really beautify and provide shade cover for years to come.

And not break in the winter.  Remember,  we offer winter tree trimming after the leaves have fallen so you can wait until then and earn a winter discount as a bonus.

Trim an ash right the first time and it will  hold its value. Thoughts?

Rain and Overwatering Trees

Wednesday, May 19th, 2010

We’ve gotten, rain, snow, sleet and hail in May 2010. You may not have to water your trees as much as past years. There is no hard and fast rule about how much water a tree needs. But you can over do it.

Taking into account the amount of snow we had in Denver, the ground is very saturated.  Consider the following factors.

  • Drainage -   Is the tree on a hill or in a low lying gully. Water will move away on a hill and pool in a gully.
  • Species – Volunteer trees need like Chinese elm need less water for instance.
  • Tree Size - Smaller trees may respond better to a drip watering system while larger trees need a deep root watering.
  • Tree context – A cottonwood is a water hog, so it will take more than its fair share from a neighboring tree. Xeriscaping,  lawn condition and proximity to pavement and other structures also play a factor.

This is just a high level overview. We’ve looked at trees that the owner thought was stressed from drought but it turned out the tree was getting too much water.  The symptoms are similar.  Here’s more food for thought on this and also some pictures of overwatered trees.

Aerial Tree Rescue Seminar – Washington Park, Denver

Monday, May 17th, 2010

On Saturday, we had seven of our tree crew members attend an aerial rescue seminar at Wash Park. It is part of our continuing education units required by the ISA. It was sponsored by Vermeer. They talked about new equipment and demonstrated a proper way to do an aerial rescue. In fact, we are now implementing a new technique into our safety training.

FYI. David has never had to do an aerial rescue in three decades of tree work. But it’s better to be safe then sorry because it does happen.

Update: Emergency Tree Removal for the City of Denver

Monday, May 17th, 2010

We recently won a contract from the City of Denver to take care of tree removal and other emergency tree services for the City and County of Denver. While we’ve been an approved and licensed tree removal company for private work and have done some tree trimming directly for the city, we are excited to serve and keep the streets safe from debris and other hazardous arboricultural situations.

Update 5/19/2010

So it turns out the City of Denver gives out notices to property owners who need to remove a tree or a tree stump that affects right of ways.  The tickets can be hefty ( up to $999 for the third citation). I can’t offer a direct link to the ticket amounts because of the city’s addiction to PDF but here is the link to download.

We received our first list from the city and you’d be surprised how many swings need to be removed.  Are these swing sets or tree swings?  Does anyone know the city ordinance on tree swings?

Lawn Care and Tree Care Service Improvements

Friday, May 14th, 2010

Something we’ve heard from our plant health clients, folks who have us fertilize and protect their trees or lawn on a recurring basis, is that we need to provide more information about the process. What’s been done, what’s coming and why. This was confirmed by a marketing strategy conducted by a consultant, Mike Hanbery.

Information matters.

Besides hiring George and adding two crews to be more responsive, we are also converting from a pen-and-ink card index, to a customized spray and lawn tracking system to better inform and serve our growing PHC client list.

Your invoice will include more detailed information about the service we provided today and for prepay customers, a running total on their balance. Eventually, the invoice will include a calendar of services provided and upcoming treatments. I hope this will help clients feel like they know a bit more about why their trees are doing so well.

If you have any other suggestions, please let us know.
