Growing potatoes in Georgia can be a rewarding and enjoyable experience. Potatoes are a hardy crop that can thrive in the Georgia climate with minimal effort. They prefer a sunny spot with well-draining soil, so amend the soil with compost or aged manure to make sure potatoes have plenty of nutrients. Plant your potatoes in the early spring, about two weeks after the last frost, and water them well. Keep the soil moist but not soggy throughout the season. Harvest the potatoes in late summer or early fall, when the tops have died back. With proper care, potatoes can be a great addition to any garden in Georgia.
Georgia’s Hardiness Zones And Climate
The majority of Georgia falls within the humid subtropical climate zone 6 through 9, with hot summers and mild winters. Summer temperatures typically reach the mid-90s (°F) and winter temperatures rarely dip below freezing. Precipitation is generally plentiful throughout the year, with the majority of rainfall occurring in the summer months. In addition, Georgia is often affected by tropical storms and hurricanes, particularly along the coastline.
Different varieties of seed potatoes
When selecting seed potatoes for growing in Georgia, it is important to be mindful of the variety’s days to harvest and the length of time you have before you want to harvest them.
Early-season varieties such as ‘Yukon Gold’ and ‘Red Norland’ have fewer days to harvest and should be planted as soon as possible for harvesting in late summer.
Mid-season varieties such as ‘Russet Burbank’ and ‘Kennebec’ have more days to harvest and should be planted in late April or early May for harvesting in fall.
Late-season varieties such as ‘Cara Russet’ and ‘All Blue’ have the most days to harvest and should be planted in late April or early May for harvesting in early winter. Be sure to select varieties with the right number of days to harvest for your intended harvest date. Some good potato varieties for Georgia include:
- Russet Potatoes: 85-95 days
- Yukon Gold Potatoes: 90-110 days
- Red Potatoes: 80-90 days
- Purple Potatoes: 90-110 days

When To Plant Potatoes In Georgia
Potatoes should be planted in Georgia in late February to mid-March. Planting should occur in the spring, when the soil temperature is between 45 and 50 degrees Fahrenheit and the daytime temperature is consistently above 60 degrees. Planting potatoes in early spring will give the plants plenty of time to develop and produce a good crop before the hot summer temperatures arrive.
- Zone 6: Around April 7th
- Zone 7: Around March 24th
- Zone 8: Around March 14th
- Zone 9: Around February 14th
How To Plant Potatoes In Georgia
Begin the planting process for seed potatoes by tilling the soil to a depth of 8 inches and incorporating organic compost. Once you have done this, find a sunny location that receives at least 8 hours of direct sunlight and place the seed potatoes.
Plant the seed potatoes with the “eyes” facing upward, leaving a distance of 8 to 10 inches in between each. Cover the seed potatoes with a layer of soil that is 3-4 inches thick, and make sure to water them adequately. As the potatoes start to sprout, add more soil to the rows to keep them adequately buried.
Water the potatoes on a regular basis and remove any weeds from the area. For those living in hot and dry climates, you may want to cover the soil around the potatoes with straw, although this is not essential.
Caring For Potato Plants
Caring for potato plants is pretty easy – they’re incredibly hardy and generally no-fuss. Potato plants need full sun and well-drained soil to thrive. They should be watered deeply and regularly, allowing the soil to dry out between waterings.
Fertilizing is also important for optimal growth. Potato plants need a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. This should be applied every four to six weeks, depending on the soil’s nutrient content.
It is also important to keep the soil evenly moist, as potatoes do not tolerate dry or waterlogged conditions. Mulching around the potato plants can help retain moisture and reduce weeds.
When To Harvest Potatoes In Georgia
There are two sure ways to know your potatoes are about ready to harvest! The first is counting backward from your current date to their planting date. Potato varieties have an approximate number of days to harvest, so consult the days to harvest for the particular variety of potatoes you’ve planted. If you aren’t sure, assume it’s around 100 days.
The appearance of your potato plants is another dead giveaway. You will know your potatoes are ready to harvest when the foliage begins to turn yellow and die back. Your plants will go through an entire flowering cycle, which is nice because the flowers are really beautiful.
Allow the soil around the plants to dry before harvesting, but don’t allow it to be dry for too long. Once harvested, inspect the potatoes carefully- they should be firm and free of green or soft spots.
Carefully dig up the potatoes with a garden fork, taking care not to damage the potatoes in the process. Once the potatoes have all been dug up, brush off any excess soil and inspect them for any damage. Discard any potatoes that are damaged, as these are not suitable for long-term storage.
Finally, gently place the potatoes in a cool, dry, and dark area for storage. It is important to only store undamaged potatoes, as damaged potatoes can quickly rot.
