Caterpillars everywhere!

Fall webworm on a Cherry Tree
You may have seen them while you were driving, you may even have them in your trees.  It's the FALL WEBWORM.  This unsightly little guy is a communal caterpillar.  They live in groups in the webs that they form at the ENDS of tree branches. The fall webworm is known to feed on more that 100 species of forest and shade trees.  In the eastern U.S., pecan, walnut, American elm, hickory, fruit trees, and some maples are preferred hosts; in some areas persimmon and sweetgum are also readily attacked.  I have them every year in my River Birch (Betula nigra).  
The initial reaction is "Oh man!  I gotta do something about this!  It looks horrible!  The reality of the fact is that this is a mainly "aesthetic" pest.  That means that trees are seldom killed by the fall webworm but can they be unpleasant to deal with.  Trees can actually be defoliated by them, but as their name "Fall" weborm implies, they do this just before the trees are going to drop their leaves in the fall. Healthy trees can actually handle this happening and will recover just fine.


The key to identification is this:  Fall webworm build their tent at the END of branches and usually are more ugly then harmful.  Eastern tent caterpillars, which appear in the Spring, form their webs in the crotches of branches close to the trunk of the tree.

So there you have it.  They're ugly, but not harmful.  Don't waste a lot of effort and money trying to eradicate them.  Welcome them to your trees as a new food source for birds.

Do You Have This in YOUR Lawn??

  Yellow Nutsedge.  There, I said it.  I know I shared with you a month or two ago about this topic, but I think it is worth going over again.  With the droughty couple of weeks we had (killing your cool season fescues), followed by rain, nutsedge is taking hold in many lawns right now.  If you have an irrigation system, and you have a low spot in your yard, that is probably the first place you will see it.     Nutsedge is a great indicator of poor drainage, over watering or leaky irrigation, as it thrives in waterlogged soil.
     To identify this pest, the first thing you will notice is it is more yellow than your fescues or Bermuda grasses.  It comes up with leaves of three, and has a triangular cross-section.  It grows faster than turf grasses so it will be a taller area of your lawn, often growing twice as tall within a week.
     If you can, hand pull small plants before they have 6 leaves.  By the time they have 6 leaves, they are already spreading underground.  If you have a bad infestation, nutsedge will kill out your turf, allowing weeds, and common Bermuda to take over your lawn.  Chemical control is successful using SedgeHammer herbicide.  This will knock out nutsedge without injury to turfgrass, established ornamentals, shrubs, and/or trees.  SedgeHammer provides post-emergence control of both purple and yellow nutsedge.  SedgeHammer also controls many broadleaf weeds and suppresses kyllinga.  It should be applied by licensed chemical applicators.  Check with your landscaper to see that they have a applicators license from the VA Dept. of Agriculture and Consumer Services, then ask them about treating your nutsedge.

Color in Design

Greetings from my Gardening Couch! It is Sunday morning and Mark and I went to new church. Part of what of the offering was to ask yourself what can I do to serve. Earlier in the morning I was thinking about the blogging series that has been taking shape. And I thought maybe I should just write, you can just pick plants out and put them in the ground. But, I do not do this when designing, I do not feel it is that casual. I feel it is a personal experience that can inspire, uplift and connect one with the Divine:) Trees and plants offer us oxygen, ( this just being one of the offerings)  we in turn can offer them direct attention and gratitude! Part of my service  is to share my experience with nature, to let others know a beautiful landscape is awesome, and yet direct intent and the desire to be more fully who we truly are and connect to the Divine and our own Divinity through gardening in Possible!!!
Now Color~ I hope you found a few colors that you are highly attracted too and perhaps even took notice of colors you prefer to avoid~ This is great information to have, it will help shape your garden design and give you some insights into your soul.
Eastern philosophy has so much information on color and its potential to affect our consciousness. From Hindu to Chinese to Japanese culture color has significant meaning and purpose. I am going to pull from several philosophies to give you a general view! Very Briefly Chakra's are energy centers  or wheels within the body, there are seven major chakras~ I have been working the Chakra system for several years as means of self awareness with a highly gifted lady,  and they are also a part of Yoga, Hinduism and Eastern Philosophy.
