  • Prevent Black Spot on Roses, Red Tip Photinia, Indian Hawthorns and their relatives by raking up old, diseased leaves and disposing of them as well as spraying when needed with appropriate fungicides.
  • Watch for aphids on the new tender growth of plants. Treat with a general insecticide or an organic product containing Neem oil.
  • Add more organic native hardwood mulch around trees, perennials and shrubs if it is less than three-to-four inches deep.
  • Cut off any fruits before they mature on spring flowering bulbs such as Irises, Daffodils and others so that the plants are not strained of plant energy.
  • Before making new flowerbeds, kill all the grass. Use products containing glyphosate. Fusilade is specific for killing Bermuda grass.
