Redmar

Family: Convolvulaceae Root Vegetable

Velvety, sunset-orange flesh with a softly sweet, honeyed flavor—Redmar delivers a rich, spoon-tender bite that feels luxurious from the first forkful.

At maturity (about 95 days), its roots form with a smooth, coppery-red skin and a glowing interior that roasts to caramelized edges and stays beautifully creamy when baked or mashed. Grow Redmar for show-stopping color and dependable performance, ideal for creating vibrant orange purées, hearty casseroles, and tangy-sweet preserves.

Culinary Notes

Chef's Note

Redmar’s honeyed sweetness and dense, creamy interior make it a spoon-food—bake or roast it until the edges caramelize, then let it go luxuriously smooth. It plays beautifully with bright citrus and warming spices that cut the richness and keep every bite from turning flat.

Best Uses

roasted wedges that brown at the edges then mash into a silky side
baked into an orange purée for lacquered Thanksgiving-style plates
thick casseroles where it stays creamy instead of drying out
tangy-sweet preserves or chutney-style spreads

Frequently Asked Questions

What pest or disease is most common on sweet potato (Ipomoea batatas), and how do I control it?

Watch for sweet potato weevil damage and foliar issues from warm, humid weather; early detection matters because tunneling in storage roots can start before you notice it. Remove and destroy heavily infested leaves/vines, rotate beds away from Ipomoea crops, and use clean, disease-free slips so you don’t introduce problems. If you see rapid spread or worsening leaf symptoms, remove affected plants promptly to slow disease pressure in the bed.

How often should I water sweet potato during the main growing phase (after slips establish)?

Once established, keep the soil evenly moist but not soggy—typically about 1 inch of water per week, increasing slightly during hot spells and reducing if rain keeps the bed wet. Avoid frequent light watering; instead water deeply so moisture reaches the rooting zone while allowing the surface to dry between waterings. Overwatering can reduce root sizing and increase the risk of rot.

How can I tell when sweet potato (Ipomoea batatas) is ready to harvest at about 95 days?

Harvest when vines begin to yellow and you’ve reached the full ~95 days, because tuber size peaks around maturity. Dig a test root first to check skin thickness and color—mature sweet potatoes have firmer skins that don’t rub off easily. Lift carefully with a fork to avoid bruising, then cure the roots in warm, humid conditions to heal minor cuts before storage.
