leafage spot often round decorative plants , such as the bottlebrush tree . Usually , the disease , which is triggered by a fungus , attacks only a handful of the tree leave . It causes small brown dot to organize on the leaves , and this interrupts photosynthesis . Leaf place usually is n’t an incurable condition , but it can seriously harm the works ’s health if it attacks more than half of the plant life or if it reoccurs every year .
To care for leaf post , make certain the Sir Herbert Beerbohm Tree get enough sun and is n’t exposed to excess moisture .
