Native Trees for South Florida

A. W. Meerow, T. K. Broschat, and H. M. Donselman

In recent years, the subject of native plants has taken on new significance in Florida horticulture. Many counties are considering landscape ordinances that require that a percentage of native plant materials be used in all future developments. Several have already implemented such ordinances. This will result in a need for wider availability of native plant materials. Woody landscape plant producers, landscape architects, and home gardeners in Florida need to become informed about and prepared for the production and cultural needs of native plants.

Edward F. Gilman and Amanda Bisson

Trees growing in urban and suburban landscapes offer many benefits to the community. However, when a tree or part of a tree breaks, it can cause extensive damage to people and /or property. A preventive pruning program is an important tool used to help mitigate the risks from tree defects. Preventive pruning helps to promote good structure, making trees more resistant to storms and other natural forces. This fact sheet describes the components of preventative structural pruning, discusses how to determine pruning objectives, the pruning cycle and, lastly, proposes how to implement a preventative pruning plan for young trees in your community.

Assessing Hurricane-Damaged Trees and Deciding What to Do

Eliana Kampf, Mary L. Duryea, Edward F. Gilman and Astrid Delgado

Right after a hurricane, communities and homeowners need to decide what to do with storm-damaged trees. Although damaged trees may seem to be dying, some trees can be restored, others will need to be removed, and still others will not require any special treatment and can be left alone. The factors that should be considered when deciding whether to remove or restore storm-damaged trees are discussed in detail in this fact sheet. This information helps to make informed decisions about how to treat the damaged trees after a storm. First published January 2007.
