Bell peppers a popular choice for home gardeners

By Clint Thompson

While commercial bell pepper producers grow this popular vegetable on fumigated plastic mulch beginning in early March, home gardeners in south and central Georgia should plant them in early to mid-April, according to University of Georgia Cooperative Extension vegetable horticulturist Tim Coolong.

He advises north Georgia residents, particularly those who are located at high elevations, to wait until early May before planting.

Bell peppers self-pollinate and grow best in warm-to-hot conditions in full sunlight. They don’t tolerate cool or wet soil.

The plastic that commercial growers use helps keep soil temperatures up if cool weather occurs in March and early April. Gardeners who plant the crop in bare ground should wait until the middle of spring.

“Bell peppers are not difficult to grow in the spring, but commercially, there are a lot of inputs involved in their production,” Coolong said. “Our climate here in the South is conducive to the successful growth of bell peppers.”

If they are planted in early spring, bell peppers are typically ready for first harvest between 75 and 84 days. The cooler weather slows the growing process. In the fall, bell peppers can be harvested about 65 days after they are planted.

A good-yielding pepper plant may produce up to seven or eight, 8-ounce jumbo peppers. Bell peppers need well-drained soil that receives between eight and 10 hours of sunlight per day, according to the UGA Extension Circular 1005, “Home Garden Peppers.” Peppers should be planted between 12 and 24 inches apart in a row, and rows should be about 3 feet apart.

Peppers’ root zone is fairly shallow. Most roots are in the top 6 to 10 inches of soil. This shallow root zone means that consistent watering is critical for proper fruit set and development, Coolong said.

Bell peppers are typically harvested when they’re green. Cut the stems to avoid breaking the branches. Peppers left on the plant after reaching full size become red as they mature. These peppers are sweeter than green peppers.

Gardeners should look for diseases and disorders commonly associated with bell peppers, namely blossom-end rot, a disorder characterized by a brown rot at the blossom end of the fruit. Bacterial leaf spot is another problem disease in peppers, although leaf-spot-resistant peppers are currently available.

“We also have problems with phytophthora, a disease we still have in watermelons. It’s the same disease, it just attacks the bell pepper plant and fruit instead of just the fruit, as is the case with melons,” Coolong said.

Store bell peppers in the refrigerator for two to three weeks. To freeze bell peppers, wash them thoroughly, cut them into strips, spread them out on a tray, then freeze them. Once the peppers are fully frozen, transfer them into plastic bags and store the bags in the freezer.

Most of Georgia’s vegetable crops are grown in the southern part of the state, which, similar to California, faces drought risks. However, as the climate warms, the area is expected to receive slightly more rainfall than usual, according to CAES economist Jeff Mullen. If vegetable production in California decreases and prices rise elsewhere, Southeast producers may consider shifting from row crop to vegetable production. CAES News
Georgia vegetable production may expand as a result of climate change 09/17/24 Maria M. Lameiras
Changing weather patterns are influencing cropping systems and where certain crops can be successfully grown. Researchers in the University of Georgia’s College of Agricultural and Environmental Sciences recently published a study in the journal Sustainability examining the feasibility of expanding fresh vegetable production in Georgia as increased temperatures and more frequent and extreme droughts threaten producers in the Western United States.

Food and fiber production adds $18 billion to Georgia’s economy 05/02/24 Jordan Powers
According to figures from the newly released Georgia Farm Gate Value Report for 2022, food and fiber production from Georgia’s 159 counties contributes more than $18 billion to the economy statewide. The Georgia Farm Gate Value Report offers a comprehensive analysis of the county-level production value for Georgia commodities. The report is compiled and published by the University of Georgia Center for Agribusiness and Economic Development within the College of Agricultural and Environmental Sciences Department of Agricultural and Applied Economics.

UGA Extension protects family farms and sensitive species 04/04/24 Emily Cabrera
Stanley Culpepper has dedicated the length of his career to supporting farmers in their mission to feed and clothe the world. For the past 25 years, Culpepper has been a weed science specialist for University of Georgia Cooperative Extension and a College of Agricultural and Environmental Sciences faculty member. Recently his job has become increasingly complex as mounting challenges around the availability of pesticides — primarily herbicides — have taken center stage in agricultural production.

Across the Southern border: The future of the H-2A visa program in Georgia 01/17/24 Emily Cabrera
As an essential part of the U.S. agricultural industry, the H-2A program offers a lifeline for farmers facing seasonal labor shortages. The program enables them to hire migrant workers on a temporary basis when attempts to hire domestic workers are unsuccessful. Yet, as the agricultural sector navigates the delicate balance between productivity and financial viability, the high costs associated with the H-2A program present a very real and present challenge for farmers striving to sustain their operations.

CAES researchers secure $4 million to tackle silverleaf whitefly problem 01/11/24 Emily Cabrera
A multidisciplinary team of researchers at the University of Georgia College of Agricultural and Environmental Sciences recently renewed a $4 million contract with the U.S. Department of Agriculture Agricultural Research Service to build upon their previous work to develop targeted interventions to mitigate the impact of silverleaf whiteflies on vegetable production in the Southeast. UGA entomologist Allen Moore leads the research team in collaboration with USDA ARS in Charleston, South Carolina.

Across the Southern border: How U.S. immigration policies affect agriculture 01/04/24 Emily Cabrera
For decades, economists have studied the impact of immigration on domestic labor markets. As a shortage of domestic farm labor has led to increased participation in the H-2A visa program, a brief look back at past immigration policies helps frame why migrants from Central and South America have largely been associated with filling necessary agricultural jobs in the U.S.
