Black knot is misery for plants, especially, for the trees of the genus Prunus, including peach, apricot, plum and chokecherry trees. Just like a termite infestation to wood, the black knot sucks away the potential of the tree to bloom and eventually kills it. It also endangers neighboring plants to catch the disease and end up in the soil. Therefore, knowing how to find a black knot, treating them and preventing them from growing again is essential information. You could also hire Arbor-All Care Emergency Tree Services in Edmonton to do all this and help prevent your trees to get other diseases as well.

    What Is A Black Knot?

    Black knot is a fungal infection targeting commonly on any weak plant. But it’s mostly seen on cheery trees in Edmonton. The infestation risks are highest in the spring season when it disperses ascospores through wind and insects targeting a wounded tissue or shoots. Thankfully the infection is not systematic, rather grows and spread from a particular point. However, the initial stages of the infestation grow inside the host tree and may not be evident in the growing season. Therefore, it’s best to inspect any signs of black knots in winter or call our specialist arborist to inspect your planation and to get rid of any black knot sitting before it spreads further.

    Hiring professional arborists will also help you plant other trees with the risk to catch black knot at a distance to prevent overall vegetation damage. Not only the black knot, but Arbor-All Tree Care Emergency Tree Services in Edmonton will also assess the trees entirely for white knot and other fungal infections. You also get a tree maintenance guide, listing trees with their level of susceptibility to getting a black knot infection. We also emphasize annual inspection in the winters as the infection damages the tree most in that time. Also, because it’s easy to inspect the tress when all the leaves are shed.

    Black knot is easily visible in the winter season with its unusual and uneven black galls. They might seem fluffy with little furs at the surface, but that’s the breathing mechanism of the infection and better be removed before it starts producing spores. When cutting the infected branches, make sure to cut it past four to 8 inches to ensure the fungus no longer prevails inside the plant. Don’t try to puncture the black knot as it may spread pores risking the human and other plants.

    How To Contain It:

    Once the black knot is removed, disposing the branches into the soil or burning them are the best solutions. After removing the black not, wash your equipment with ½ cup bleach into a gallon of water to disinfect. Deal every area after cleaning the tools by soaking it into the solution for 5 minutes. You can also spray commercial fungicides directly of the pruning equipment to get the job done. The best overall prevention method is pruning and sanitation of the trees. If not, you’re more likely to experience the problem every season. Also, use copper sprays for trees suspectable to get the infection for a better bloom and fruit production.
