With over 77,000 rivers and streams and an average rainfall of 55 inches per year, Alabama is a state blessed with natural water resources. Catching and reusing water is an ancient technology that has current value to save energy, money and conserve an important natural resource.

If interested in collecting rainwater, first you must decide if you want to collect on a small or large scale. For personal collection, you can use something as simple as a rain barrel. Wood, metal, or plastic are all good containers for rainwater collection, as long as they do not have residues of harmful chemicals. It is wise to use a dark container, or paint the container dark to discourage algae growth. The container used for collecting should be covered, with a screen protection at the opening to keep mosquitos out and minimize leaves or other materials from entering. For larger scale collection, cistern systems are recommended. In 2010, Birmingham-Southern College installed a 15,000 gallon cistern that captures rainwater off of the roof and uses it for landscape irrigation. According to bsc.edu this practice is saving 50,000 gallons of water per year.

The Alabama Cooperative Extension System hosts residential rain barrel workshops each year to demonstrate construction, placement and uses of rainwater harvesting systems. Harvested rainwater can be used for household chores like watering lawns/gardens, irrigation in the yard, flushing toilets, and washing cars. Be sure to check with local plumbing codes and ordinances if you are interested in using rainwater inside your home.

Collecting rainwater saves money and energy. The collector will save money by using the free resource instead of treated water. “Why not take advantage of what’s free and falling from the sky,” said Alabama Extension specialist Dr. Eve Brantley. “Collect it and hold it until you need to use it rather than constantly using water that has been treated. It saves energy, it saves money, and it’s a good use of water resources,” she said. Although Alabama has plentiful water resources droughts occur about every 12 years. It is smart to practices water collection and conservation so it becomes a habit. It is anticipated that climate variability will result in more frequent and/or more extreme droughts. It is smart to practice water collection and conservation so it becomes a habit.Don’t hesitate to start collecting rainwater now.

Growing grapes in Alabama has been practiced since the state was first settled, but has only been successful in certain areas for dedicated growers. To produce quality grapes one must learn about their area, the grape varieties to grow, perfect the setup and devote plenty of attention to the grapevine.

Muscadines are a type of grape that grows well almost everywhere in Alabama. They are native to the Southeast and are used for fresh consumption, juices and wines. Muscadines thrive because they are resistant to a key grape killer, Pierce’s Disease (PD). PD is caused by a bacterium carried by an insect that feeds  on infected  vegetation, acquires the bacterium and can inject it into the sap of the grapevine. The bacterium multiplies and clogs the xylem vessels of the vine  so water and nutrient  transportation to plant organs is being limited. Consecutively, over time the plant fails to receive nutrients and dies.

Cultivars resulting from crosses between American species or between  French and American species are known as hybrid bunch grapes. Elina Coneva, Extension Specialist for Alabama Cooperative Extension explains, “American species produce an inferior quality fruit, but can be resistant or tolerant to PD. Because of this quality they are used in crosses with French cultivars that possess high fruit quality, but are susceptible to diseases including PD which is the major factor preventing French or European grape production in the Southeast.” Eleven PD  resistant or tolerant hybrid bunch grapes including  ‘Black Spanish’, ‘Blanc du Bois’, ‘Champanel’, ‘Chardonel’, ‘Conquistador’, ‘Cynthiana’, ‘Favorite’, ‘Lake Emerald’, ‘Seyval Blanc’, ‘Stover’, and ‘Villard Blanc’ have been recently tested in Alabama recently:. Top three performing hybrid bunch grape cultivars in north Alabama conditions are ‘Black Spanish’, ‘Cynthiana’, and ‘Villard Blanc’. Regionally produced hybrid bunch grapes yield wine, juice, and jams. According to North Alabama Horticulture Research Director Arnold Caylor, ‘Black Spanish’ is processed to wine, whereas ‘Conquistador’ is used for juice or jam. Hybrid bunch grapes are susceptible to foliar disease and are attacked by several insect pests so it is important to use pesticides when growing grapes in Alabama.

Progress continues to be made in Alabama toward growing grapevines resistant or tolerant to PD. Currently, Coneva is testing PD resistant French grapes developed by  the grape breeding program at U.C. Davis in California. Based on their upright growing habit these vines are trainedin a vertical shoot positioning system, which also facilitates more efficient  pest control, while concentrating the crop load within a compact fruiting zone. French grape selections are showing promise for Alabama environment and for the first time can provide an opportunity for cultivating high-value French grapes in Alabama and the Southeast.

Learn about the area, choose your type of grape, then set up to plant. The site should be in full sunlight most or all day. If planning to grow several vines, it is best to have straight rows for level land and contour rows for hilly terrain. “The spacing between rows will depend on the vigor of the cultivar of the grape that you are growing,” said Caylor.  Make every effort to establish a permanent sod between rows to reduce soil erosion. Use a trellis system to train the vines horizontally, managing a dense canopy by dividing it, allowing more sunlight to reach the fruit renewal zone. Prepare a large hole for the entire root system; set the plant at the correct level, fill the hole with topsoil, firm it, water liberally and do not add fertilizer. Hand weeding and hoeing is necessary as there are not many choices for herbicides for the first year of growth. Pruning should be done while vines are dormant.  Summer  hedging can help maintain the vine canopy and ease vineyard operations .

February is the best time to plant grapevines.
