| [Image: fireworks]Home Gardener Notes on Current Ornamental Plant Evaluations The LSU AgCenter’s Hammond Research Station evaluates many ornamental plants for landscape performance under south Louisiana growing conditions. Evaluations include annual flowers, herbaceous perennials, trees, shrubs, roses, crape myrtles and more. |
| [Image: leaf spot]Entomosporium Leaf Spot Entomosporium leaf spot, caused by the fungus Entomosporium mespili (formerly E. maculatum), is a common disease of various woody ornamentals in the family Rosaceae.

| [Image: herbaceous perennials are gaining popularity]Nutrient Requirements of Herbaceous Perennials in Newly Established Landscape Plantings Herbaceous perennials are continuously gaining popularity in landscape plantings. However, nutrient requirement of many species in this group during their first year establishment in landscape is still unknown. Seven herbaceous perennials were studied for their growth, flowering, and overwintering survival in respond to a variety of fertilization regimes and fertilization recommendations were generated based on the restuls. |

The most spectacular of these is Brazilian Red Hot. We are currently evaluating the following varieties at the LSU AgCenter’s Hammond Research Station. |
| [Image: spring in the azalea garden]Azaleas: An Overview of Landscape Care and Considerations from a Gulf States Perspective Azaleas are spring showoffs, even though some newer varieties now bloom in other seasons. Most of us may not realize that azaleas represent the main nursery crop grown in many states in the southeast and along the Gulf Coast. In Louisiana, they represent 7% of all nursery plants grown.There are many factors that play a role in the success or failure of an azalea planting in a landscape. These issues include planting time, sun exposure, soil pH, bed preparation and more. . . |
| [Image: azalea drought damage]Azalea problems answered (Distributed 06/16/11) Azaleas either do great in Louisiana, or they do poorly. The LSU AgCenter regularly receives questions on azalea issues this time of year, but more inquiries than usual have come this spring. |
| [Image: purple flash]People's Choice Awards from Landscape Horticulture Field Day - 2009 Green industry professionals attending the landscape horticulture field day at the LSU AgCenter’s Hammond Research Station in June were given the opportunity to “pick their winning plants” from the sun garden evaluation trial gardens at the station. Over 340 varieties were planted this year. The planting mostly consists of annual bedding plants and herbaceous perennials, but new roses and some “companion” woody ornamental shrubs (such as Southern Living plants) are also included. |
