I mentioned in July that I would count the number of recently planted trees along Queens Road West.  From Selwyn  Avenue, to Kings Drive there were nine (9) dead trees that I counted and continuing on Kings drive to Morehead, there were ten (10) that died.  That is a lot of trees and several years ago in 2015 (I will check date) I called the city Arborist early in the spring and he said they had lost 38% of the trees they planted.

Things have really changed in the last few weeks in that we have had a lot of rain.  Actually, the rain has been spotty and did not land in my yard  as much as several other places.  From observations, and what I read this is a cycle that will continue.  All these weather situations are related.  Excessive heat (in places all over the world) has become an issue. that makes forest fires a real threat as they are now and have been in our western states.  The California Car five as of today has burned more than 80,000 acres and is only ??? contained. Serious fires leave open ground that can not absorb rain water, and that creates flash floods and situations for landslides and rock slides, and not the least major and minor dam failure...  as an example the Oraville overtopping in California in early February 2017.  Check this link to how unprepared anyone was for the almost horrific disaster that would have released all the water from the tallest dam at 795 feet in the United States.  This would have been a major, major, disaster for California and the entire US.

If you find the Oraville Dam invigorating episode, then check out the the total collapse of the Teton Dam in ????  and then the near diaster of the Glen Canyon Dam  in ???  19??

In China about the same time the Teton Dam Collapsed, the Chinese Government hid for 15 years the destruction and death of about 300.000??? people from the Banqoi Dam in 1973. https://www.internationalrivers.org/.../the-forgotten-legacy-of-the-banqiao-dam-collap...

July 12, 2018
The drought continues with possible thunder storms on July 17th.  This is serious for all plant material.  We have had more days over 90 degrees every summer for quite a few years.  What is not obvious is that the soil moisture dries out as the summer progresses.  Depending what happens later in July, August, and September, and maybe October, the soil probably will continue to dry.  So far we have  not seen problems with the major tree canopy.  Shallow rooted trees have and will continue to suffer and die.  We will start to see deterioration of major trees if the weather continues as it has.

I plan to count the dead newly planted trees on Queens Road West, and check with Charlotte Landscaping to see the percentage of replacements needed for the city as a whole.  Why do this?  We need to get a handle on what we as individuals can do to help protect the trees.  To my knowledge the average citizen does not know how to evaluate if a large shade tree needs water.  If we do not address this issue it could very costly in dollars and loss of trees.

July 11, 2018.
Here is the more coming referred to from the July 4th..  We had a long period of almost no rain.  When it is 90 degrees outside, any rain gets used up quickly.  The heat evaporate it, and the rain often runs off rather than allowing the water to seep into the ground.  If you have grass or other vegetation, more of the rain will go into the ground.  All these floods we see on TV are partly because the world had lots of roofs, roads and parking lots, and hard surfaces in general.

It has been 11 days since we had the July 3rd rain of 3 to 4 inches.  I have a small vegetable garden with drip irrigation on 4 tomato plants.  They are doing fine but the ground near them is quite hard.  I used a pointed solid steel bar about 1 inch in diameter and 5 feet long to punch some holes in the ground to support a bamboo tripod to grow cucumbers on later in the fall, and could only get the bar in the soil about 1 inch.  We really need more rain.

July 4, 2018.  Boy that rain was quick  3 to four inches of rain last night.
 That does not mean the drought is over.  more coming 

July 4, 2018  Alert.  We are in the middle of a severe drought.
I have been gone for a time, and this web site is a little behind.  I came back after 13 days on the west coast, and there had been only one light rain shower while I was gone.  I have been back since June 20, 2018, and it is super dry.  I am fortunate to have an irrigation system so my plants look pretty good considering how dry it has been.  I use drip irrigation on my landscaping, but even that has not been enough.  So far the larger shade trees look good, but we still have lots of summer to go. Most of July, August, and September will be dry before it starts to cool down.

Plants like shallow rooted azaleas are in bad shape and will likely die if they have started to wilt severely.  I have a hedge of Laural along the edge of the driveway which has been there for 20 plus years.  A few of the plants were wilting three days ago See Photo below, and I watered them down hard.  The badly wilted branches will not come back but might put out some buds on the stems.

In the summer of 2015, we also had a bad drought very similar and lost many newly planted trees.  There are at least 10 new willow oaks planted this spring along Queens Road West which are dead.  Rather than repeat what I wrote in 2015, check this link.   (July 12, 2018 Some of the Photos on this link are missing because I posted this information in 2016.  Maybe they went out of business?)

June 1, 2018
Hot and muggy, and we did have a pretty hard rain last night. Clear and sunny today probably have storms this afternoon.  Serious damage from flooding on the Natahalla River where I like to fly fish and I expect several other rivers in the mountains have seen lots of flooding. The town of Ashville really was flooded badly and more heavy rains expected.  All of this reminds me of the fact that I think climate change is real.  Our 25 and 100 year floods have now become 500 and 1000 floods.  There is so much documentation about this, it is really not necessary to repeat all the facts.  I will choose some and report 

May 29,2018
Lots of rain should be on its way from Tropical storm Alberto??.  A storm does not become a hurricane until the wind speed reaches 72 miles per hour. Any storm including a Tropical Depression can deliver lots of water  When ever there is 3 inches of more of rain, there will be flooding to one degree or another.  If the drainage area is large and one gets 3 to 8 inches of rain the results can be devastating.  I live about 40 feet above Sugar Creek that runs through Freedom Park.  I measured the difference with an anemometer which tells the exact feet above sea level.  I do not think we are at great risk because the flood plain around the creek where we are is quite wide.  If one is anticipating buying a home, it is always a good idea to check out the flood potential.  What used to be 100 year flood comes often and a 1000 year flood can happen.  We who live in the Charlotte area were lucky that the flood  in 2016?????? that clobbered South Carolina, just missed the lower part of Charlotte.  In fact I 77 down close to the South Carolina border was flooded.   Keep your eyes open and have an emergency plan.

April 30,2018

April 18, 2018 I expected to see cankerworms today but did not.  They should be out, but we had a very weak infestation in this area (Myers Park).  If anyone out there has information, let me know.  I went fishing over a long weekend and could have missed the hatch.  BTW I always enjoy the mountains this time of year.  The green spring foliage was on the lower mountains but not at any higher elevation.  it was interesting how much more green was visible on the way home four days later.

April 11, 2018
Spring is here... Several days ago (April 6, 2018) I happened to stumble upon a short article I wrote back in April of 2000 which is 18 years ago. To me this has been a rough winter, but plants are starting to bloom on exactly the same schedule.  I thought our weird winter would slow things down. I would say that azaleas were  out in full bloom yesterday, April 10th.

Take a look:
April 4, 2000

Every year I wonder where we are in the spring as compared to last year or the year before.  Below are a few things happening right now which gives us an idea as to what will happen next year also.

Trees flower about 3 to 4 weeks earlier here in Charlotte, then they do up north in areas such as Rochester New York.  Washington is about 3 weeks behind.

To day the boxwood leaf miner came out.  I have seen the little orange fly emerge as early as the last day of March and as late as the 15th of April.  Most azaleas are in full bloom or will be in a day or three.  Daffodils are mostly gone, only the latest varieties are still hanging around.

Willow oaks in full leaf although some of the young trees in cooler areas only are partially out.  The tassels of the willow oak are falling but have not reached their peak.  They are a real mess and pollen from the oaks and pines will coat everything soon.

Sweet gum pollen will turn ponds dark coffee color.  We actually spray them soon to keep the sweetgum balls from forming.  This works well if you are interested.  It beats cutting down the trees and the balls are really a pain.

I will continue to post as plants come into leaf.

I observed the azaleas in my own yard starting to flower and even took a few photos which I will post here.
 

March 29, 2018
It feels like spring out there today.... finally.  So far we have missed the rains and tornadoes that are racing in from the Midwest.  I did miss the nasty weather of a freeze, rain, and snow that was here a couple of weeks ago.  I was fortunate to be in South Africa where is was early fall, nice weather, but a severe drought in Cape Town.  Here is what one of the large reservoirs looked like from the Air.  Part of the issue for Capetown is that they have had double influx of people in the last several years and that has put a real strain on infrastructure.

 I am back from a little time off and have reached a turning point in that I have a different focus on life.  Maintaining a business property takes work. There are taxes, property to be maintained and unexpected things that happen because of weather or other unforeseen things.  I plan to maintain these pages and keep my Observations to continue to add content to the site.

March 3, 2018
I guess we need to get back to the business of dealing with things that did not get sold at my sale.  We got rid of a lot of small things, but some of the larger items are still here.  I am moving stuff from the property as the new owner takes over soon.  I intend to remove the photos of what is gone which means that if the photo is still there, so is the item available. Give me a couple of weeks to get that done as I have other priorities.

February 23, 2018
Since the timing of the cankerworm seems to be on schedule I think we can assume that the emergence will be late March or early April.  The eggs are laid in the top of the trees and after the first cankerworms hatch, they will be green and about 1/16th of an inch long.  It used to be that you could see small cankerworms on the Tanglefoot trap, but since there are so few females, I have seen very few egg cases on the trunk. We will have to hear from others in areas where there were heavier infestations.  So much for now..

February 18, 2018
I have not seen any cankerworm for a week.  I think they are done for the season.  Since I have not heard anyone come up with a better thought as to why there have been dramatically fewer cankerworms, here is mine.  We had a drought just before the big freeze.  It was below freezing at sometime during each day for 10 days or more.

I saw plants die this year that have not before.  At my office I have had three separate     ten gallon containers with three types of water lilies in them.  They have lived happily for 15 years in those three containers and all of them froze oout this season.  The cold might have been the critical factor but the drought could have added to it by weakening the cankerworms just below the surface of the ground.

February 11, Sunday 0 cws today total  cws for the year 46.  .
 

 

 

 

 

December 19, 2017 Tuesday
I got a call today from the North West Charlotte that 4 cankerworms were spotted on a “pin” oak tree.  I suspect that the tree was a willow oak in that the long leaves of the willow oak often confuse people who have heard of the Pin Oak which has deeply indented leaves and has a more traditional oak leaf shape.  The pin oak also has the bad habit of keeping its leaves on most of the winter.  In other words you will have to rake leaves all winter long.

I put up my trap last night with no Tanglefoot on itsee more

December 17, 2017 Sunday
Looks like we will get a little rain over the next few days.  We need it, as we are in a drought which is not good for trees and shrubs going into dormancy.

December 13, 2017 Wednesday
Yesterday, the cities contract crew banded about 1/2 of the city trees along Queens Road West.  This morning about 10:30 am I took this photo.  It was windy and this is not the entire trap, but here within 24 hours there are a significant number of leaves in the trap.  Please note that there are a lot of leaves on the ground and invariably the city will send out a bunch of leaf blowers in a few days and really blow the leaves up on the trap.

leaves reduced on trap qrw day after

 

On the way back down the road, I saw that a lawn care crew was just finishing up cleaning a rather large yard,  There were three men with blowers and they did a really good job of getting the lawn clear of leaves. You can see them in the background in this first photo below.  The cankerworm trap is ruined.   see below

Hold off a few days from putting up your cankerworm traps and watch out for the leaf blowers.

It’s not just leaves, it is dust and other debris that clogs up the glue on the trap.  Look closely and you will see what I mean.   These traps have to stay on the trees until mid April ...4 months.

December 12,2017 Tuesday
Don’t be in too much of a hurry to get the traps up.  I see city traps with tanglefoot full of leaves already.  In much of Charlotte, the trees still have lots of leaves.  There are more details on the cankerworm page.  The cold front should arrive tomorrow and that has delayed the real cold that we need to bring them out to crawl up the trunk.  more on cankerworms
December 10, 2017 Sunday  
The temperature only dropped to 28 last night; I expected 26.  I started thinking about the cold weather coming and all the other things I needed to do this Christmas Season.  About 3:00 Am after a good sleep I woke up and realized I had not protected several outside faucets.  One in the back yard is a copper pipe that stands up from the ground about 24 inches.  If it freezes and burst, it is a pain to fix.  Fortunately, I know a little about soldering copper, and if I were to not take care of this I know I would have a broken pipe.

At the same time I have 3 hoses in the front and back yard each of which has a spray nozzle.  If they are drained they are not affected by the cold, but if there is water inside them they will break.  I gathered the faucets up also and went back to bed and slept

December 6, 2017

The leaves are flying from the trees, and with the coming cold front and wind, I think most of the trees will be rid of their leaves soon.  If you are doing the banding yourself you should put the bands up now, but do not put Tanglefoot or other sticky material on the band. (see more on banding).

When I used to rake my yard, I realized that it would take about 100 leaf bags to clean up all the leaves.  It  did not matter if I raked leaves once a week during the leaf falling time, or if I raked once a month, or waited until the end  of the season, it always took about 100 bags.  I have fewer willow oaks now, but my neighbors might not.  All of these leaves came from one yard.

 Sixty Three ( 63) Bags of leaves from one residential yard on QRW.

December 2, 2017 Saturday
It will several more days before we see female cankerworms start climbing the trees.  The 10 day
forecase for Charlotte shows us getting into the 25 and 28 degree range by Saturday December 9th.  Shortly after that I would expect to see some activity. There are certain areas around Charlotte that are not as affected by the heat of the city, and they might experience colder temperatures sooner than we do.  I have several people who report when they see cankerworm activity and that is a big help to all of us. I still see lots of trees loaded with leaves.

wio big reduced to 4%

Big Willow Oak

 I photographed this large willow yesterday (Friday Dec first), and as you can see there are many leaves to still fall.  At the same time a light wind was blowing leaves out of the trees, and we are expecting rain soon.  If that is the the case then certainly on large trees the leaves will fall, and it would be ok to put up traps  I is ok to put the band on the tree now, but do not put the sticky material on until we 3 good cold days.

Personally I would wait a few days to put Tanglefoot on because I always put a very thin 1/2 inch band on my lone large tree and will not put up the remaining tanglefoot until I see modest activity. 

I also recognize that lots of people hire tree companies to put up the Bug Barrier trap and the way it is made to shield the glue this trap can be put up earlier than the traditional Tanglefoot trap. There are other reasons I don't care for the Bug Barrier trap and you can read about that here.

November 3, 2017  Thursday Thanksgiving Day

    It is close to the cankerworm migration up the trees.  I read an article a couple of days ago in the Charlotte Observer that this week and next were the appropriate time to band trees for cankerworm. 

    I take issue with that because the willow oaks are loaded with leaves.  We need a good rain, and wind to rid the trees of leaves.  Back when cankerworms first became a problem after Hurricane Hugo in 1989, the timing for putting up cankerworm traps was about Thanksgiving.  Each year it seems to start later and now is later in December.   See this link

     It takes a good Hard Freeze to get  the cankerworms crawling.  What that means is that it needs to be 27 degrees F. or cooler for about 3 days in a row to get the female canker worms moving.

    If you band too soon you will have a lot of leaves captured in the Tanglefoot.  If you use other products that protect the sticky stuff you are probably ok.  The wind will tend to blow leaves under the Bug Barrier trap.  Actually the other day I heard about 6 leaf blowers all making tremendous noise at the same time.  There were 3 going two houses down from me and a like number up the street.  I had to put on a head phone like ear protectors just to work in the yard.

    Leaf blowers are really bad about blowing up leaves on to the cankerworm traps.  It might be the operator who is careless, but in general if you put up a trap too early, the leaf blowers will ruin the trap.

    Every year I watch the city band trees on the median of Queens Road West. A day or so later, the city or their contractor comes by and blows up so many leaves that the traps are covered.  I will post a photo here later.

    I am up and running at last.  Just in time for the fall cankerworms it appears.  Presently I am in Rochester New York.  It is amazing how different the trees are here. It is especially obvious as we drive along the highway.  I have been interested in the oak trees.  They are in the process of turning from their fall colors to a blend of just brown.  Conspicuously, the white oak are just brown,  A few Scarlet oaks have retained their fall color.  The Scarlet oak is one we don’t often see in the Charlotte area.  Mostly we have willow oaks, white oaks, some Northern red oaks, water oaks, Southern Red oak ( this one’s leaf looks like a candle flame).  Lesser seen are the chestnut oak and some mossy cup oaks that probably came from seeds brought down by a  Dr. Tilley a dentist I think in about the 1930’s.  There are some of these original trees on 7th Street, and I went by and got some great examples of their acorns.  Photo here....soon.  The name is Querscus macrocarpa which means large cap.  I planted several of these over the years and one is on the property at Lake Norman Yacht Club. It is now about 50 feet tall and producing acorns for the past 10 yearsor so.  More on acorns later.

    As of February 17th, I have not seen any more female cankerworms.  I do have some eggs on the trap where the male cankerworms were attracted to the stuck females.  We can expect these eggs and the eggs up in the trees to hatch in late March.  Keep your eyes opened and you will see small green worms on the traps.  Ten days later you should see some defoliation.

    I will write more about this later today.  I want to make some comparisons to previous years.  I find what we have seen this year in terms of the overall migration to be very abnormal.

    II have not checked my trap since January 25th.  I expected that there would be about 30 cankerworms a day.  The actual count was 20 cws and 150 would have been the number if my guess had been correct.  I also have noticed that the cankerworms have been coming up from the back side of the tree in this case, the shady side of the tree.  In the past that has been an indication that the migration was slowing down.

     Finally another normal day for cankerworm movement.  I counted 9 female cankerworms on the trap today.  I looked back over some historical figures.  In past years as the migration started, we would see days like this:  3,5,2,4,6,8 and then a few days up to 24.  One year on Christmas day, there were 100 cankerworms captured.  A few trees had 5000, to 8,000 insects for the entire season  read more

    It rained a little bit last night but not enough to wet the bark and I trapped 13 female cankerworms.  This seems to be more toward normal movement.  Still we have seen a very late start to the cankerwom migration.

    Also of interest, is that most of the city trees I have seen are showing few cankerworms.  I suspect that in certain parts of the town the numbers will much larger.

    Well, finally what I would consider a normal day. Seeing 8 female cankerworms on the trap was a good sign.  Since I know they are moving in other parts of the city, I think we will see more favorable days ahead.

    Today there were no cankerworms on the trunk of my tree which surprised me since I thought they were moving upward on Tuesday the 17th.  I also checked the two street trees in front of my home and there were no cws on the first street tree and possibly one on the second tree.  I mashed it so there would be no carryover from today.

    At least today I have found that some other parts of the county are having a good bit of cankerworm activity.  The Highland Creek area as well as Concord are having a good bit of activity.  Concord has been pretty bad for several years.  Mint Hill was spotty last year and I  don’t know how that  is doing this season.

    I have had a number of cankerworms get through the Red & Tacky so I  will stop separating the two types of sticky material.   Note that my  total of 36 is not much different from the count I made on another large willow oak across the street yesterday.   I counted approximately 40  because it was hard to see under the trap.

    The ice and snow are mostly gone, and there are cankerworms on the trap.   I did not have time to count them, but will do so later this morning.
     
    I attended the CIA (Charlotte Arborist Association) meeting last night  and the general consensuses is that the cankerworms either have not  started en mass yet except in a few isolated cases.   One person  mentioned that a trap directly across the street from me in an  individual’s yard was loaded with female cankerwormsl   I hustled across  the street about 8:00 and did count approximately 40 female cankerworms  in the trap.   This was a Bug Barrier trap, and it is hard to count the  numbers because they are on the inside of the trap and hard to see.
     
    Why the difference from the norm?   I really don’t have the answer, but this is a healthy willow oak that is growing in a bed of English Ivy.   Maybe the ivy insulates the ground from freezing and the worms started moving sooner that those trees that are on bare soil more or less void of any  mulch.
    I will explore this later.

    Today it is in low 30 €™s and not suposed to get much warmer.   This has been a  strange seson, and I have had several comments about how late the season is this year.
    Below is an email I got from Jeff Peppard.   Jeff  was the one who used the Red & Tacky (RT an abbreviation I plan to  use more in the future).
    Jack,
     
    I haven't seen any females as of 01-05-17 after thousands last year.    Could we possibly have effected the life cycle or just not cold enough    this year yet.
    Also, I explained last year that the females are  too weak to get through the "red n tacky" grease. They don't get stuck  like Tanglefoot.   They   merely get the grease on their legs and fall to  the ground. I literally   had thousands on my oak fall last year.
    Strange season so far, but I'll hunt them buggers down.
    Thanks,
    Jeff Peppard

    I realize that I will need to put up more Red & Tacky because it is pretty thin.

    cankerworm bu 2We had 2 inches of rain here last night and the cankerworms did not care to come out and climb the trees.
    I did discover some insects that I have seen many times.   They are  colored exactly the same as the lichen on the tree trunk.   I looked them up and that is what the two photos below are.   It turns out the a  Lacewing larvae.   The cover them selves with dried bits and pieces of  the
    lichen for camouflage.   The move about and search for small insects like  aphids etc.   The two links below are very informative and have some  excellent photos plus a lot more detail than I have  provided.http://jimmccormac.blogspot.com/2010/11/lacewing-uses-lichen-camouflage.html

    Blog above identifies this as a camofloged lacewing larvae.

    It might seem strange that there have only been six cankerworms so far  this year.   I do not know why.   There is speculation that it might be to the severe drought that we had during the summer of 2016.   The official record for Charlotte was 40 days without rain, but at my home I went  for another 20.   The storm that brought rain to parts of Charlotte after 40 days just happen to skirt my home.
    It would be logical to assume that the dryness killed lots of cankerworms  that breed in the ground, but I don €™t think that has anything to do with the late start.   Here is why, I happen to have an irrigation system for my yard and I also try to be conservative with water for the grass but I did keep things going through the drought and the cankerworms are just  as slow in my yard as they are on the street trees in front of my  house.
