Distinguish and Treat Black Spot


Rescue Your Roses.


 

Recognizing black spot on roses tends to be easy because the fungal spores create tiny black spots on the foliage. When left untreated, the black spot spores infect the plant, causing the leaves to turn a sickly yellow color and fall to the ground.

 

If you are battling black spot on your rose bushes, ready your pruning gear and grab your PreGro Plant Sprayer. Before using this portable, hand-held sprayer, clear the ground of all the diseased leaves and remove the spotted leaves from the shrubbery. After pruning, apply a paste made of ground cinnamon and cooking oil to the freshly cut plant tissue to help seal the wounds.

 

Mix up your own home-made fungicide, which can be an effective low-cost solution for treating black spot. Pour your organic fungicidal solution into the easy-to-fill glass container.

You Will Need:

  • 1 cup organic whole milk
  • 2 cups warm water
  • 3 drops liquid dish soap *make sure there is no bleach in the dish soap
  • Quart-sized pitcher
  • Stirring utensil
  • PreGro Plant Sprayer

DIY Recipe to Battle Black Spot

 

Directions

Using a quart-sized pitcher, combine 1 cup organic whole milk with 2 cups of warm water. Add 3 drops of non-bleach liquid dish soap to the mixture and give it a quick stir before pouring into the PreGro Plant Sprayer glass container. Never shake the PreGro Plant Sprayer when the glass container is attached to the sprayer. The PreGro Plant Sprayer utilizes aerosol technology, but does not contain CFCs. For optimal spray, hold sprayer between a 90 degree angle and a 45 degree angle. Thoroughly drench the rose bushes with your milk-based fungicide, making sure to spray both the top and bottom of the leaves. Spray the roses once a week until you see the black spot diminish.

 

Important Tips:

  • Spray once a week on both affected and healthy roses to make sure fungus spores do not spread.
  • Test your homemade solution on a single plant to make sure the solution is not too strong and will not have adverse effects.
  • Spray this natural solution on your affected plants in the early morning or evening so a hot or sunny day will not cause the solution to heat up and burn the plant material.
