As a gardening and landscaping expert , I have come across many cases of diseased blue spruce trees , particularly those taint with the Cytospora pestilence fungus . When it comes to identify a diseased spicy spruce , there are some telltale signs to reckon out for .
One of the first thing you may point out is spread out branch dieback on the tree , often starting with the lower branch . This dieback can progress upward over metre if the disease is leave untreated . It ’s of import to inspect the Sir Herbert Beerbohm Tree nearly and see for any branches that come out dead or are show sign of declination .
Upon close scrutiny of the stagnant branches , you may observe the front of awkward white sap . This sap is a characteristic symptom of Cytospora canker infection in blue spruce trees . It is a effect of the fungus attacking the Sir Herbert Beerbohm Tree ’s bark and have sap to oozing out . The viscid sap can attract insects , further contribute to the tree ’s decline .
In increase to the physical symptoms , you may also notice a change in the overall appearing of the blue spruce tree . Diseased trees often demo a thinning canopy and a world-wide want of vigor . The needles may turn a dull grayish - green color or even brown in terrible cases . This change in color indicates that the Sir Herbert Beerbohm Tree is struggling and may not be able to support its foliage properly .
It ’s worth noting that other factors can make like symptoms in blue spruce tree diagram , such as drouth stress or other disease . However , the presence of embarrassing bloodless sap is a key indicator of Cytospora canker infection specifically .
I have run into several instances where blue spruce trees in landscapes have fallen victim to Cytospora pestilence . In one particular suit , a homeowner notice that the scummy outgrowth of their puritanical spruce were turning brown and perish off . They ab initio slip it for normal seasonal shedding but presently realize that the dieback was spreading rapidly .
Upon closer inspection , I noticed the telling sticky white-hot sap on the dead branches . This confirmed my mistrust that the tree diagram was infected with Cytospora pestilence . I rede the homeowner to take quick action to halt the paste of the disease and prevent further damage to the tree .
A pathologic low spruce tree infect with Cytospora pestilence will typically exhibit scattered branch dieback , starting from the lower branch . The comportment of pasty white sap on the beat arm is a clear indicator of the disease . Additionally , the tree may show signs of a cutting canopy , obtuse or brownish needle , and an overall lack of vigour . It is all-important to plow the issue readily to forbid further decline and likely departure of the Sir Herbert Beerbohm Tree .
