I re-landscaped my f... #188592

Asked June 05, 2014, 12:07 PM EDT

I re-landscaped my front yard in St. Paul last week. One of the flower beds laid out by the architect is for brunella looking glass and I note that many of the leaves are speckeled with gray spots/some associated notching of leaf edges. Checking with the nursery, they tell me that their instock plants exibit the same feature and speculate that it may be rust or a fungus but that it can't be too serious, otherwise they wouldn't stock it. Would you agree ? Any tips on management ? I have to water adjacent new sod daily. Could this have a detrimental effect on the plants ? Thank you in advance for your advise.

The leaves will develop dried-out brown spots if the soil dries out. They also get tiny roundworm called foliar nematodes.  The following information is copied from Michigan State article. “Symptoms generally appear in mid-summer.  Triangular brownish-black blotches appear between the veins of the foliage, leaving the leaves looking scorched and desiccated.  “The presence of foliar nematodes can be confirmed by harvesting several leaves, shredding them and soaking them in a jar of lukewarm water for 12 to 24 hours.  The nematodes move into the water and are visible with a compound or dissecting microscope.  Look for very small, translucent roundworms swimming in the water.  It may take a few minutes to recognize the nematodes because they are clear, but once you do, it is a relatively simple diagnosis.” Go here to read the complete bulletin:

Return the plants if you find nematodes.  Overhead irrigation will spread this worm to other plants so try to avoid wetting the leaves.
