usda map

(Distributed 02/03/12) When the U.S. Department of Agriculture released its updated Plant Hardiness Zone Map in January, it prompted quite a bit of conversation in the horticultural world. The new map had been long-awaited and was the first update since 1990. It indicates the average minimum winter temperatures for all areas of the United States.

(Distributed 01/27/12) Pruning is one of the activities that many home gardeners have questions about. When to prune? How to prune? Why prune?

(Distributed 01/20/12) One of the great flowers that continues to be popular in our Louisiana landscapes is perennial verbena.

Prune crape myrtles properly
(Distributed 01/13/12) We are midwinter in Louisiana, and this is the time when crape myrtle pruning becomes commonplace. Unfortunately, these are among the most abused trees in Louisiana’s residential and commercial landscapes. Crape myrtles need only occasional pruning, in most cases, to obtain the desired landscape effect.

Try a horticulture resolution this year
(Distributed 01/06/12) Happy New Year! It's time for new projects, new resolutions and making plans for another gardening season in Louisiana.
Redbud tree gives early flower color
(Distributed 12/30/11) Redbuds are one of our more popular early spring-flowering small trees. The most common redbud species is the Eastern redbud – Cercis canadensis –the one we primarily plant in Louisiana.
Holiday cactuses brighten the season
(Distributed 12/23/11) Although poinsettias are typically associated with the holidays, another group of plants to consider are the Thanksgiving and Christmas cactuses. These are highly recommended for long-term enjoyment.
It’s not too late to plant cool-season flowers
(Distributed 12/16/11) Most Louisiana gardeners know about the new Louisiana Super Plants program launched by the LSU AgCenter in 2010. This program highlights tough and beautiful plants that perform well in Louisiana landscapes. The AgCenter announces new selections each spring and fall. We still have time to add cool-season flowers to the landscape.
Mulching is good landscape practice
(Distributed 12/09/11) Mulching flowers, trees and shrubs is a great sustainable landscape practice when done correctly.
Wintertime lawn care mostly means relax
(Distributed 12/02/11) Frost has settled over the majority of the state. This means many of our warm-season lawn grasses are going dormant for the winter. December begins the bleak time of the year for warm-season turfgrasses in Louisiana.
Plant trees now through midwinter
(Distributed 11/23/11) November, December and into mid-January are excellent times for planting trees in Louisiana. During this period, the soil is still warm, encouraging vigorous root growth, and trees will have several months to get established before summer’s heat.
There’s still time to plant pansies, violas
(Distributed 11/18/11) The ideal planting time for cool-season bedding plants in Louisiana runs from late September through early December. Some of our common cool-season flowers prefer the earlier planting dates, and some do better with the later planting dates.
Kale and cabbage produce appealing foliage all winter
Redbor kale
(Distributed 11/11/11) Ornamental kale and cabbage are becoming increasingly popular as fall bedding plants in Louisiana. Alternatives to garden mums and pansies, these plants have feathery leaves with robust colors that make them well suited for landscape and container plantings.
Sasanquas provide color during late fall, early winter
ShiShi Gashira camellia
(Distributed 11/04/11) Sasanquas are one of our most popular flowering shrubs for the late fall through early winter. Also known by the scientific name Camellia sasanqua, sasanquas are typically smaller-growing than the plants we normally call camellias. They also have more finely textured foliage. They bloom from mid-October through December or January.
