Crab Grass and Other Lawn Invaders

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.

To treat black spot fungus, there are organic fungicides that will not harm your plants that you could use to treat the disease.  Neem oil is a more natural remedy that you could also use when diluted with water in a plant sprayer, neem is an oil that is pressed from the evergreen tree.  A third remedy is a gallon of water, a large tablespoon of baking soda, and a splash of neem oil; the baking soda will create an inhospitable ph level on the leaf while the neem oil helps the solution to stick to leaves.
