Are Your Evergreens Yellowing?

Yellowing evergreen Jun 11, 2013 |

 

Yours aren’t the only ones. People all over our area have noticed the phenomenon and it’s been covered in our local press (Hampton Summer Guide 2013, pg. 68). Our team at Whitmores has been receiving phone calls all spring from our clients, concerned about their pines.

Yellowing or browning foliage is a sign that your plant is suffering from salt burn. Most plants are sensitive to salt exposure, and excess salt in a plant’s environment can cause salt burn on foliage. When Hurricane Sandy hit, its strong winds blew salty air across Long Island. Salt was deposited on plants and collected in the soil. Salt dehydrates the tissue of plants, it can enter the root system and cause toxic effects, or even prevent the roots from bringing up water entirely.

Evergreens are often the first to display symptoms, visible in their discolored yellow or brown foliage. Damage may have started to appear this spring, but residual effects can show throughout the summer, and even for years to come. Most plants should recover, but some may not and will continue to decline in health may die. Weakened plants are also more susceptible to secondary effects like pests, diseases or environmental stresses.

Keep in mind that salt burn isn’t exclusive to Evergreens; it just may be more noticeable in them.

 

What you can do to mitigate salt injury to your plants:

•Organic based or natural fertilizers. Stay away from salt based fertilizers

•Proper irrigation to flush salt from the soil

•Perform a soil analysis, and add missing nutrients and minerals as needed

•Monitor your evergreens and other plants throughout the summer
