Why are my cotoneaster dying? - FindAnyAnswer.com.
I need help figuring out how to diagnose and treat a disease in my landscape planting.There are three creeping cotoneasters in my front yard.One of the cotoneasters has a bit of die-back.Several branches have brown leaves that are dying.The other two plants don't seem to have been affected.I will ruin my landscape if I replace this one with a smaller one.
Mites are the most common problem with cotoneasters.The pests suck the plant juices and cause the leaves to fall off.During hot dry summers, these are a common problem.To control the mites, spray the plants with a strong blast of water.If the damage continues, consider applying insecticidal soap, or another eco-friendly product labeled for controlling mites.
There is a disease called fireblight.There are cankers on the dying stems.Prune 6 inches behind the canker.Between cuts, treat tools with a 70% alcohol or 10% bleach solution.The plant may look bad but it can recover if you remove the bad parts.The stored energy in the roots will help the plant quickly regain its original size.Pruning during the dormant season will reduce the risk of future infections.lush growth that is more susceptible to the disease is promoted by excess and high nitrogen fertilization.If the plant dies it is best not to replace it with another fireblight susceptible plant.If you feel lucky, you could replace the dead plant with a larger shrub to make up for the discrepancy in size.It could be replaced with a low growing spreader.The cranberry cotoneaster is mixed with a small spreading juniper to create a beautiful combination.
