I recently purchased a home that has cedar hedging all around the perimeter. My two side yards have cedar hedging around 5-7 years old. And the back is around 20-25 years old, around 12 feet high, and always well maintained. The side yard hedging is around 6-8 ft high. Im wanting them to catch the back hedge. The neighbouring properties have tall maple trees that block a portion of the sun light each day on the two side yard hedges. (they are healthy) Now they do see sun light for 60% of the time. But this year didn't grow more than 8-10 inches. The oldest hedge is starting to show some signs of thining in areas. My questions is: What can I do to fertilize them? Is there any method of injecting the ground around them to really give them a boost? Any maintenance tips would be great! Thank you in advance.
If only in certain sections the thinning will probably be due to shading and not to a nutrient deficiency, making fertilizing not pertinent. (Sample soil and have it tested to find out something about nutrient situation). If shade cast by maples possible source of thinning pruning maples may be answer, if tops of hedge shading own bottoms and causing thinning may be possible to prune tops to be more narrow and allow bottoms to fill in. With most conifers always have to work around problem of leafless growth inside of outer shell not re-sprouting adequately - if at all - when cut back to.
Thanks for your reponse Ron! My problem areas that are thinning, I don't think are affected a whole lot by the shade issue. I will take a few pics of the area and post them so you can see what Im really talking about. The problem isn't at the bottom or the top, its in very small areas scattered in the middle, but no real signs of really dying off, other than really starting to thin out. (but i guess that means no new growth.) I will post asap. Thanks
