Hosta fungus leaves. Usually this disease doesnt mean hosta la vista baby but it sure makes them look like they were in a gunfight. In addition to hosta it is also an infection daylily astilbe peony phlox ajuga delphinium and potato. Sclerotia can remain inactive in cold weather and are activated. Symptoms of hosta anthracnose include large irregular spots with darker borders.

Plant fungicides are usually effective against fungus that leaves rusty discolorations on hosta leaves but in the case of anthracnose the fungicide should be put on leaves where there is not yet any fungus.

This particular fungus is difficult to control as it lives in the soil and overwinters beneath mulch.

Although hostas are relatively disease free they can be infected with several common plant diseases. Hostas are herbaceous perennials prized for their ability to grow in shaded areas. This disease first targets the lower leaves but then quickly spreads to the upper ones causing a path of wilted brown leaves. The disease fungus produces very small round fungal seeds of sorts called sclerotia at the base of the petiole.

Therefore it often helps to pull back any mulch from the plant. Eventually the centers of the spots fall out and leaves become ragged. Usually this disease doesnt mean hosta la vista baby but it sure makes them look like they were in a gunfight. Symptoms of hosta anthracnose include large irregular spots with darker borders.
