Keep garden rows wide enough to cultivate, narrow enough to shadow out weeds

By Paul Pugliese

As a University of Georgia Cooperative Extension agent, I answer hundreds of gardening question. This week, a gardener wanted to know how far apart to space her garden rows. The short answer is: it depends.

Row spacing in raised bed gardens is often closer than in traditional plowed gardens. For a raised bed garden, you probably don’t want boxes and/or rows wider than 5 feet, so you can easily reach into the garden and pull weeds or harvest vegetables without having to walk into the raised bed. Because raised bed gardens are usually maintained without machinery, rows can be closer.

For plowed garden plots, row spacing is often determined by the width of your rotary tiller. For most tillers, rows should be at least 36 inches wide. This way you can go back between the rows and lightly cultivate for weed control until the crop starts to fill in between the rows.

For most crops such as beans, corn, tomatoes, eggplant, peppers, okra, peas and squash, 36-inch row spacing would be the minimum. Some gardeners prefer slightly wider rows for certain crops like okra because it’s just a pain, literally, to have to harvest without some headroom.

When using cages for tomatoes, peppers and eggplants, add a little extra space for convenience. For vine crops such as sweet potatoes, cucumbers, cantaloupe, watermelons and pumpkins, leave at least 60 to 72 inches between the rows. Rows spaced 72 inches are perfect for making two passes with most rotary tillers for weed control until the vines begin to run.

So what about planting crops even further apart? You can plant most crops at a greater distance with the exception of corn. Corn does best when planted in at least two rows within a few feet of each other for good pollination. Keep in mind that the wider your row spacing becomes, the more weeds you will have to deal with.

When spacing your rows, the goal is to maximize crop growth and yield while out-competing weeds. Closer spaced crops tend to shade out competing weeds once the crop leaves begin to form a canopy over the middle of the rows. You still need to control the weeds with tilling and hoeing early in the season. If you do a good job managing those weeds early on, then you should have fewer weeds as the season progresses.

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.

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.

CAES leads effort to tackle emerging threat to watermelon, cucumber production 12/07/23 Jordan Powers
Seven East Coast states harvested nearly 102,000 acres of watermelon and cucumber in 2019 and 2020, representing more than 62% ($410 million) and 45% ($180 million) of the U.S. production of the two crops, respectively. Growers of cucurbits — which include melons, pumpkin, squash and cucumbers — face numerous challenges in production, leading to decreased profitability and less produce on grocery shelves.
