Managing Japanese Barberry

Managing Japanese barberry is a royal pain, but it may be one of the best health protective landscape management tasks one can undertake.

Those who have followed this blog over the years likely remember many of the posts on how Japanese barberry is taking over many areas of Connecticut’s woodlands and how Japanese barberry creates a perfect environment for ticks and mice.

It’s hard to find a Connecticut resident who has not had a bout of Lyme disease or another tick-related disease. Now, there’s another disease – Powassan virus – linked to black-legged ticks. While no human cases of Powassan virus have yet been identified in Connectucut, if it is transmitted by black-legged ticks it’s only a matter of time.

The increasing disease risk from black-legged ticks makes controlling Japanese barberry even more important. I outlined various control methods in previous posts – linked above.

Serious stands of Japanese barberry, like the one above, may require heavy equipment, like a brush hog, followed by repeated control methods of regrowth. But regular control is the only way to eradicate Japanese barberry from a property.

A property walk now, when Japanese barberry is one of the only leafed-out under story shrubs, identifies how much and where this invasive shrub is growing. If you are fortunate, as in my case, to have little Japanese barberry invasion on your acreage you can use my control method – pulling out young, and still small, shoots and leaving them on a nearby rock or fallen tree to dehydrate and die.

This is the method I used with yesterday’s finds in the woods.

But, this area needs to be revisited one or two times throughout the growing season, and definitely in early autumn, to watch for and control re-sprouts from any left-over roots in the ground. Japanese barberry is known to re-sprout with vengeance. Subsequent Japanese barberry walks help identify any shrubs/sprouts previously missed.

If Japanese barberry is growing anywhere on your property – but particularly anywhere near your house – do yourself, your family, and Connecticut’s woodlands a huge service … remove it and control its return.

Morning in the garden – April 18, 2015

Spring has, at last, taken hold and greenery and flowers are awakening all over the garden, enough to start the morning in the garden series to document the growing season in my zone 6a, south-central Connecticut gardens.

The well-established crocus planted in the south-facing front beds are done blooming while those in the cooler rear beds still greet the morning sun.

Nearby, are fleeting blossoms of Iris reticulata.

The crocus and early iris blooms show my love of blue and purple, as do the potted violas on the front porch.

The sand crane statue, that just a few weeks ago was almost completely buried in snow, stands tall and seems relieved to be perched among growing plants.

In the front beds the Lamb’s Ear borders are shaking off their sad winter face and soon will be nothing but fuzzy gray foliage, while allium foliage shows where 3′ tall globes of violet will stand come June.

 

Thankfully, local deer leave both Lamb’s Ear and allium alone.

 

The two dwarf white pines planted last autumn came through the winter well in spite of being totally buried from January through early April.

The weather forecast promising two warm, sunny days should entice the first magnolia and bloodroot blossoms to open …

 

and the sun will soon dry the dew droplets captured by emerging Lady’s Mantle foliage.

Crocus blooms, finally!

Though these opened at least a week later than last year, and about three weeks later than in 2013 and 2012, finally … we have crocus blooms!

If I had posted photos of these crocus flowers yesterday, you might have thought it an April Fool’s joke.

No joke. They are real and really are in bloom. Crocus tommasinianus, aka ‘tommies’, are the only variety of crocus not devoured by the voles that frequent my gardens. If you have voles, these are the crocus to plant.

Over most of my landscape snow still reigns; releasing its hold ever so slowly during day time temperatures in the 40’s and 50’s. But spring is popping in the warmer areas near the house and walkways. It could not be more welcome.
