Rivercities Garden Club

Meeting 1/4/04

 

Program - Gardening with Native Plants  - Sandra Gibbs

There are four categories of soil here in Louisiana

Plants which like dry don't do well with wet. However they will do reasonably well if they are planted in one level away from what they like.

Sun exposure

 

Native plants fromTexas to the east coast will do well here except the west Texas plants from the mountains require alkaline soil.

Plants that are obtained from nurseries close to home may grow better.  When buying plants from a nursery make sure that they are nursery propagated.  These plants cannot be dug and shipped. There is simply too much stress on the plant from root injury and shipping.  Depend on seed and cuttings rather than digging the plant out of the ground.

 

Sources of Information

La Native Plant Society  meets at the science building at Centenary College on the fourth Thursday of the month.  There is a sale of native plants by the  plant society on the 4th Thursday in March att the highland center.

Sandra Gibbs is a member of the Master Gardener program. She provided substantial help with the Master Gardener Program The World of Gardening last fall.  She owns a wholesale nursery specializing in native plants.

The use of native plants in a suburban setting can be advantageous especially on small plots

Naturally belong to a given region climate and geology, they become acclimated to the weather.  Here in Shreveport we have cool wet winters, long hot dry summers,   and lots of bugs, critters, and  fungi.  As a result these plants are hardier and more disease resistant.  These plants need much less maintainence to survive.  Wildlife are much more likely to use native plants.  All plants have an idea of what they need to survive  Native plants extremely flexible and will live just about anywhere.
