Red Ruby
95d to harvest
Velvety skins in rich ruby-red set the stage for Red Ruby’s quietly luminous flesh—firm, creamy, and wonderfully smooth when cooked. With a steady 95-day rhythm, this market-class red potato forms dependable, oval tubers that hold their character beautifully for roasting, mashing, and hearty sauces, while also shining in fresh salads for a crisp, clean bite. Grow Red Ruby for a harvest that looks as sumptuous as it tastes—an elegant red tuber with a satisfying, spoonable texture.

Frequently Asked Questions
How often should I water Red Ruby potatoes during the main growing phase?
During active tuber bulking, keep soil consistently evenly moist—aim for about 1 inch (2.5 cm) of water per week, split as needed for hot spells. Don’t let beds swing dry for long periods, because uneven moisture can reduce tuber size and increase misshapen tubers. Check moisture 2–3 inches down; water when it’s drying there, but avoid waterlogging that can trigger disease.
How can I tell when Red Ruby potatoes are ready to harvest?
Harvest when plants begin to yellow and die back, typically around 95 days from planting for mature Red Ruby. For “new potatoes,” you can dig earlier once plants have flowered, but for full size wait until foliage has largely senesced. Before lifting, gently scrape soil back and check that tubers have set skins that don’t rub off easily.
