We’re your neighbors who love gardening and want to pass that love along.  Here you’ll find tested advice about gardening in the Coastal Bend area of South Texas.  The lack of severe winters, heat and humidity, wind, unique soil, and lack of water – all conspire to form a unique and challenging environment for growing plants. Whether you’re a newcomer or an experienced pro, we’ve got the scoop on the latest and greatest in gardening for our area.

  • What to plant?  Take a look at “In Our Coastal Gardens” under PUBLICATIONS AND RESOURCES at the top of the page.  This booklet is available free (thank you San Patricio Water District) at the AgriLife Extension Office and covers trees, shrubs, palms, tropicals, and even what not to plant.  If vegetables and herbs are your cup of tea, we’ve got the when and how for our area.
  • When plants have problems.  Contact our help desk, either by phone or come in to the Agrilife Extension Office.  We have experienced gardeners available as well as printed articles on plant diseases, soil conditioning, insects, and all topics garden-related.  Bring in a sample of the problem (in a zip-locked bag) and we’ll put our best detectives to work on it.  We also come to you – request a visit from our “Tree Team” to sleuth out what ails your prized arboreal specimen.
  • Meet and learn from other gardeners.  Throughout the year we have talks by local and area experts.  Our monthly Brown Bag talks are one hour long at noon – take a break at lunch and find out what’s new and exciting.  Seminars are held at various times of the year and are a more in-depth look at timely topics.

Who are the Master Gardeners?  We are members of a non-profit program of Texas A&M Agrilife Extension Service designed to increase horticultural knowledge in our area and around the state.  Started at Washington State University in the early 1970s, the Master Gardeners program spread to Texas A&M University in 1978 and then to all 50 states and 4 Canadian provinces.  Currently, the program has almost 100,000 members who volunteer 5 million hours of service per year to their communities.  Master Gardeners is a federal and state non-profit program and depends totally on donations and fund-raising for its programs and activities.

Locally, the program is led by Ginger Easton Smith, County Extension Agent for Aransas County.  To join Master Gardeners, we offer a 3-month training course starting in August, with an Introduction & Registration session in mid-July.  Please contact the Extension Office, 892 Airport Road, Rockport, Texas, 78382, 361-790-0103, for more information.



Steve Byrns, Texas A&M AgriLife Extension, August 26, 2016

The mosquito-transmitted Zika virus is a potential threat to the health of unborn babies in Texas and other states, and the Texas A&M AgriLife Extension Service has stepped up efforts to educate the public on ways to protect themselves from this new menace, said agency entomologists.

“While people enjoy outdoor activities and travel this fall, it’s important to remember that our first line of defense against Zika is to avoid being bitten by mosquitoes,” said Dr. Sonja Swiger, AgriLife Extension entomologist at Stephenville. “The Aedes aegypti and A. albopictus mosquitoes that transmit Zika occur commonly in our backyards where their eggs are laid and larvae live in standing water. Like other mosquito species, they are active at sunrise and sunset, but commonly bite throughout the day as well.”

Swiger said it’s important to remember the “Four Ds” as a first line of defense. They are:

— Drain: Empty standing water, thus eliminating mosquito breeding sites.

— Dress: Put on long sleeved shirts and pants when going outside.

— Defend: Apply mosquito repellent when going outside.

— Dusk and Dawn: Avoid outdoor activity during these two most mosquito-active periods.

Simple steps such as repairing screens on doors and windows are critically important to keeping mosquitoes out. Managing landscape water features is another key area in the fight against the spread of the Zika virus, according to Swiger.

“Mosquito dunks, commonly sold in garden centers for mosquito control in home water features, can be used to treat water that cannot be readily drained,” she said. “The dunks contain insect growth regulators or mosquito-specific bacteria to effectively control mosquito larvae. Neither is harmful to fish or other aquatic organisms.”

Dr. Mike Merchant, AgriLife Extension urban entomologist at Dallas, said that fighting Zika will be much different than fighting West Nile virus.  Aedes mosquitoes infected with Zika are not easily detected, so health officials have to rely on actual human cases to identify hot spots.

“In addition, city and county truck-mounted sprayers are less effective at killing Aedes mosquitoes, so stopping these mosquitoes in each and every backyard is even more important.  Everyone will need to pitch in,” he said.

“Anything that holds water should be dumped or treated. Breeding areas can include sites as benign as containers under potted plants and bird baths. Other trouble areas are old tires, empty cans and bottles, kiddie pools, buckets, boat tarps and even clogged gutters.

“It doesn’t take much water for them to reproduce,” he said.  Small containers can hold enough water to breed mosquitoes.  Aedes mosquitoes don’t travel far from their larval habitat, so if you’ve got them, chances are you unknowingly raised them.”

Swiger said there are many mosquito repellents available, but all approved formulations share two features. The U.S. Environmental Protection Agency (EPA) registration of these repellent products means first, that the active ingredient has been tested and is safe for people to use, and second, that it’s effective in repelling mosquitoes when used as directed.

“EPA and the Centers for Disease Control have evaluated scientific reports and conclude mosquito repellents containing DEET, picaridin, or oil of lemon eucalyptus, called IR3535, as active ingredients provide reasonably long-lasting protection from mosquito bites,” Swiger said.

“Users should always read and follow label instructions. Most repellents can be used on children over two months of age, with the exception of those containing oil of lemon eucalyptus, which should not be used on children younger than 3 years old. For babies under two months of age, infant carriers fitted with mosquito netting are recommended. Pregnant and breast-feeding mothers can safely use EPA-approved insect repellents.”

Constant vigilance is the key to slowing Zika and other mosquito-borne diseases such as West Nile virus said Swiger.  “It’s the global world we live in today,” she said. “As people travel and return from areas affected by Zika, some will return carrying the virus. When Aedes mosquitoes bite infected people, they acquire the virus. The mosquito then transmits it to an uninfected person, passing the virus to them.”

Swiger said that as of this writing, there are 122 recorded cases of Zika in Texas, all travel associated, except for one contracted sexually from their partner who traveled. No Texas mosquitoes have been found to be infected.

“Epidemics are expected as infected people arrive and locally acquired infections occur,” she said. “As the many media accounts report, women infected by the virus while pregnant are known to have babies with severe neurological defects. Aside from mosquito infections, additional cases may occur from sexual transmission of the disease. So, avoiding mosquito bites to protect yourself from infection is the most important thing you can do to defend against this new mosquito-borne virus threat.”
