Lawn Invaders

As we have discussed in a previous post, fungus can pose a threat to your healthy looking lawn.  Aside from fungus, there are other unwelcome intruders that can bring down your curb appeal and break up an otherwise uniform and lovely lawn. Some of these invaders include dandelions, yellow nutsedge, snails and slugs, and Japanese beetles. For the plant intruders, there are some solutions that could be bought at a local store to kill off dandelions, as well as help beat back the yellow nutsedge. The nutsedge however will be more of a process to remove, since the tubers (or root base) can survive for up to three years.  Nutsedge loves wet soil, so make sure your yard has proper drainage to avoid these from getting a foothold. As for the snails and slugs, one remedy is to put small dishes of beer around your yard, and when they try to drink it, they will drown before they have a chance to cause damage. You could also line your lawn with diatomaceous earth, which is non-harmful to humans and your lawn, but will harm and prevent the snails and slugs from crossing into your yard.  This solution will have to be re-applied after it rains though.  Japanese beetles can be a summer long threat.  The beetle’s grubs burrow in the lawn and cause it to go brown.


Some weeds thrive in the hot months of summer when our lawns are at their weakest.  Most desirable turfs use seeds that do well in the cooler months of the spring and fall, and when there is excessive heat in the summer, they go dormant and turn brown.  This is when heat loving weeds strike.

Black Spot Fungus

Diplocarpon rosae, or black spot fungus does not just affect roses.  This fungus can affect any plant in your garden that has fleshy leaves or stems.  Identifying this fungus should be easy enough, since the name accurately describes the first stage of infection.  Plants with this disease have black spots, and when it progresses, the leaf around the spot starts to turn yellow, until eventually the entire leaf is yellow and falls off.  On the plus side black spot fungus does not kill plants, but it is very unsightly.  This fungus grows in the spring when temperatures start to climb into the sixties, and does not stop until temperatures reach the mid eighties.  This fungus also thrives when plants are wet for 6 to 9 hours in the day.
