Spring tree care

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

 

    March marked the start of our transition from winter to spring.  Now that the snow has melted  (we hope,)  it’s a good time to examine your trees for winter damage.  We often expect our trees to be self sufficient and  tend to neglect their well-being.  

     After the frost is gone, thoroughly water trees that have been subjected to de-icing compounds.  This will move the chemicals through the soil and away from the tree roots.   Watering before the ground thaws will create runoff and pollute soil and ground water. 

     If your trees need to be fertilized, wait until the ground has completely thawed.  Fertilizer run off wastes money and also contributes to groundwater pollution.

     If, and only if, an insect problem exists, dormant oil sprays can be used once the temperature reaches a constant 40 degrees.  Dormant oils are used to control some scale insects and overwintering insects. 

    Rabbits and voles girdle trunks at the base.  Damage will appear as a lighter area on the trunk, primarily as teeth marks.   The damage interrupts the flow of water and nutrients to the roots.   While you have no recourse for the damage, it is wise to monitor the health of the tree as severe damage can kill a tree.

    Tree wraps should be removed in the spring as the temperature warms.

    Complete pruning prior to trees leafing out.  Storm damaged branches should be removed as they occur. 

    If you’re planning on adding trees to your landscape, now is a good time to visit our local nurseries and greenhouses for suggestions and recommendations.        Personally, I’m going to find the shadiest spot under the big walnut to plant my chair and enjoy my favorite summer beverage.

New feature: Your Questions

Every so often, I see comments posted that ask gardening questions that I’m sure many of our readers would be able to help answer. With that in mind, a new category, “Your questions” has been added, so readers can ask and answer gardening questions. I’ll also try to find expert answers if no one else can help.

 

Click on the arrow next to the categories box, at the right, to find this feature.

 

 The first questions come from Pam who asks the following:

 

 I have started a flower garden in the front of my home which is facing east but does get some south sun on part of the garden area. I love flowering plants but I have not done a good job with finding appropriate plants. Does anyone have ideas of various plants that are perennials to put here?

 

Pam (who lives in Marion, Iowa) also asked:

How soon should you start trimming the fruit trees: apple and pear? What other tips should I know to get the trees ready for spring? I have heard a lot about spraying the trees so what should I use?

Leora left the following question:

 We have heard of growing potatoes in tires, but need to know the procedure. We have two big tractor tires to work with. Please help us.

Does anyone have advice for Pam or Leora? Please add your suggestions in a comment below.

 

If you have any questions of your own, you can post it in a comment here, or send an email to: cindy.hadish@gazcomm.com

Please include your location – Northern Iowa, Central Iowa, etc., – as that will help tailor the responses.
