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
What pest or disease problem is most common on Solanum tuberosum (potatoes like Red Ruby), and how do I control it?
Watch for late blight (often starts as dark, water-soaked leaf spots that spread quickly during cool, wet weather). Remove and destroy infected foliage immediately, avoid overhead watering, and improve airflow by spacing plants so leaves dry fast. If the problem keeps appearing, apply a labeled late-blight fungicide early in the infection cycle, rotating modes per the product label to reduce resistance.
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.
