Norway maple trees are tough , stalwart shade tree often found in northern landscapes . They are popular in urban setting , because they call for only a small root space , furnish abundant shade and are highly resistant to ozone . The Norway maple will tolerate a multifariousness of soil conditions and a dirt pH anywhere from 4 to 7.5 . When trim this tree , focus on thinning the crest to allow more air and light to penetrate the upper branch , and move out any dead or pathologic offset . Always dress trees in the winter , during dormancy .
Corrective Pruning
When pruning dead and diseased branches , locate the branch collar andthe branch bark ridge . The branch leash is located on the underside of the base of the branch , and is easier to name on a deadened ramification , because its lively tissue paper look distinctly unlike from that of the drained leg . The leg bark ridge runs parallel to the angle of the branch , along the stem of the tree , on the opposite side of the branch collar . Both of these must stay on entire if the tree is to heal after you remove the stem .
Cut outside the branch bark ridge , and tip your cut downwards , away from the tree ’s prow . You want to achieve a clean , snug cut , as near to the branch axil ( where the branch joins another branch or the root word ) as you may without damaging the outgrowth bark ridgeline . The nigher you are able to cut , the preferably the combat injury will heal . If you leave a stub , the wound will take longer to heal because it has to grow over the extra tissue .
If the branch is large , support it with one hired man , and make the track with the other paw . If it is too gravid to indorse , you will have to lighten up it by using the three - cut method acting . The first cut is a shallow notch on the bottom of the branch , outside the arm catch . Make the 2d cut all the way through the branch , opposite the notch , to remove the weight unit , leaving a short butt . Make the third cut outside the bark collar to hit the nub . apply the three - baseball swing method for live or dead branches .
Crown Thinning
The upper arm of the tree diagram make up the crown , and the summit can be quite large on a Norway maple , with very dense leafage . While this is ideal for providing much - needed shadiness in hot weather , very slow foliage can also inhibit the passage of light and air to the upper branches . Light and air are essential to tree diagram wellness and the bar of disease . Never absent more than one quarter of the crown at a sentence ; removing more than that will put unjustified emphasis on the Sir Herbert Beerbohm Tree .
Remove any branches that rub or cross other branches , or branches that are grow downward and low to the primer coat . Look for atomic number 23 - shaped Angle where two lateral branches total together . The co - rife stems that come together in a V - shaped slant are not as strong as those in a uracil - shaped angle . The United States Forest Service recommends removing some of the lateral branch , which will advance stronger branches to dominate .
