Frightful weather?

The following is from Linn County Master Gardener, Claire Smith:

           

It’s a debatable issue:  is the weather outside really frightful today?  Or, is it all in your perspective?  I was out and about this morning but arrived home in time to sit here at my computer plunking away for this week’s blog and watch the beautiful huge flakes of snow wafting to the ground. There’s just something mesmerizing about an Iowa snowfall.   Right now, right outside a kitchen window, a Cardinal is perched in a lilac bush sheltered in a blanket of white. What a sight!

            Speaking of birds, what will you do with your live tree after the Holidays?   How about, after removing the ornaments (especially the tinsel) propping the tree in your perennial garden?  It will add winter interest as well as shelter for birds that enjoy feeding on the seeds of coneflower, rudbeckia and liatris.  Or use it as mulch by pruning the branches and covering perennial and bulb gardens.  I’ll bet your neighbors would volunteer to let you take their trees, too. 

            Have you observed what wildlife visits your garden?  Their antics can be quite entertaining.  Note which plants helped bring them into the landscape. 

            Brush snow off shrubs and evergreens as the heavy wet stuff will cause breakage and damage. Prune only broken/damaged branches now.  

            Most importantly, investigate environmentally friendly methods of removing snow and ice from sidewalks and driveways.  Calcium Chloride is more expensive, but it is easier on your plants. Watch for new plant-friendly products entering the market. 

            And, if you haven’t found the perfect gift for a gardener friend, think about a journal, plant labels, hand pruners, flower scissors, a harvest basket (my second favorite choice), a gift certificate to a favorite garden center, or (my first choice!), a load of well seasoned manure, delivered. Yes! You read correctly!  It will be an inexpensive gift and certain to bring smiles to everyone’s faces.

Salt, de-icers and trees

The following is from the International Society of Arboriculture. The group’s Public and Industry Relations Manager, Sonia Garth, encouraged readers to also check out their Web site at www.treesaregood.org for more information.

 

     When winter snow and ice begin to fall, so does the salt, on driveways, sidewalks, and streets to aid in melting away potential hazards. Keeping our surroundings safe during the winter months is important, but salt can be a serious threat to our trees, when used without caution.

     “Excessive exposure to salt can cause widespread damage to your trees, leading to permanent decline and sometimes death,” said Jim Skiera, Executive Director of the ISA. “The problem with salt damage is that it might not show up on your trees until summer, when deicing salt is the last culprit you would suspect.” 

     To minimize the damage done to trees by deicing salts, Certified Arborists at ISA offer the following tips:

1. Use less salt. Mix deicing salt with abrasives such as sand, cinders, and ash, or use alternatives such as calcium magnesium acetate and calcium chloride.

2. Protect your trees from salt trucks on the street. If possible, set up barriers between the street and your trees to keep salt spray from hitting tree trunks.

3. Plant salt-resistant trees. Trees such as the sycamore maple, white spruce, willow, and birch tend to be more salt-resistant than other species. How well they fare varies from climate to climate across the country.

4. Improve soil drainage. Add organic matter to your soil to help filter salt deposits.

You can also keep your trees healthy by taking care of their basic needs. Other tips that will help combat the damage done by deicing salt include:

·        Irrigate to flush the salts from the soils in spring

·        Mulch sufficiently to reduce water loss.

·        Control pest infestations and destructive tree diseases.

     If you feel your trees may be susceptible to salt damage, contact a local ISA Certified Arborist in your area.

The International Society of Arboriculture (ISA), headquartered in Champaign, Ill., is a nonprofit organization supporting tree care research and education around the world. As part of ISA’s dedication to the care and preservation of shade and ornamental trees, it offers the only internationally-recognized certification program in the industry.
