Clematis

Does your deciduous Clematis look like this?  If it does, cut it down to 6-10 inches now.  In February, these vines will begin to produce new buds all along the stem.  The brown dry leaves will remain and look bad all year.  Not only that, the plant will become a huge overgrown mess. Remember that what ever growth they produced last year will be produced again this year.


The first sign of Spring.

Here it is.  The first sprout of my Siberian Iris.  Soon the blooms will be adding some color to my yard and warmer, dryer days can't be far behind.  I don't know about you, but when I see fresh green growth in my landscape it rekindles my gardening interest, even if the weather is still poor. Siberian Iris is one of the first bulbs to sprout, even before Crocus!  When I see them I know all other bulbs are close behind.


Winter tree and shrub pruning

Why is winter a good time to prune plants?  Well the main reason is that it is the best time to see branch patterns.  Most pruning can be done at any time.  However, many prefer winter because it is easier to see crossing and oddly shaped limbs.  Pruning is the single most important aspect of plant care and landscape improvement.  Bad pruning can destroy a tree or shrub but horticulturally correct pruning will bring out the best.


Sprinkler winterization

I would say Winter is here.  So far we have had several light freezes and more are on the way.  If you have not had your landscape sprinkler system winterized yet be sure to do so.  And just as a tip, winterization is not just turning off the controller or opening a valve drain.  Proper winterization includes the use of an air compressor to blow the water out.  This is the only way to properly dry out the whole system.


Weird weeds

Liver and worts are not most peoples favorite landscape features.  However, over the last few years the low growing and mat forming Liverwort weed has taken over.  This weed has moved into landscape from the forest over the last 3-5 years and appears to be very happy.  It is more of a moss type plant.  One of those primitive beginning of time organisms.  While this would be a good biology topic it is a problem in the landscape.


Bronze Birch Borer

I hate this bug.  It is killing one of my favorite tree types.  Birches are beautiful trees and are an important part of many landscapes.  This insect bores into Birches in the spring and can live within the tree for up to two years before emerging.  During that time it feeds on the vascular tissue below the bark.  This damage reduces the flow of water up and the flow of sugars down into the roots.  If left alone this pest can kill a tree within two years.


Rooftop gardens

One of the latest trends in landscaping is up on the roof.  Eco roofs are often simple and shallow plantings of ground cover plants.  The main point is urban cooling and reduction of stormwater runoff.  Eco roof plantings have made the news a lot in the past few years but the old standard rooftop garden is my favorite.


Skunk damage in lawns

This time of year Skunks get hungry and your lawn is a good place to hunt.  Many of you have Skunks in your neighborhood and don't even know it.  Skunks wander around during the late evening and are very quiet.  They dig for earthworms and other insects.  In a single night they may dig 10-15 holes like this.  It can be quite a mess.  Often they will be in backyards because in front yards they are bothered by cars and street lighting.


Is it Summer yet?

I have to say I don't mind having Spring for Summer.  I prefer 80 degrees to 100 degrees.  I think plants do also.  During most summers plants will stop growing during hot weather.  High temperatures bring on dormancy.  However, not this year.  Plants are continuing to grow.  What does this mean?  Well it means that you must keep up on watering.  Lots of people are not watering enough because it is cool.  Don't do that.  Water just like you would if it were hot.  Ninety percent of the water used in landscapes is from lawns, shrubs and trees absorbing it, NOT from evaporation.  Be sure to ap


There is more to life than just being green

It seems that everyone wants to be green.  Well I for one think we are green enough here in the Northwest.  It's always good to add some color.  While it has been a slow start with the cool spring, many Annuals are now blooming and growing well.  Summer is a time that has little color due to the fact that most of our blooming trees and shrubs are at their peak in the Spring.  This is unfourtunate because we are often indoors during that time trying to stay dry.  Now that it is more likely that y
