Growing Texas 1015Y Supersweet Onion

‘Texas 1015Y Supersweet’ is an open-pollinated onion prized for its exceptional sweetness and large, softball-sized bulbs. Light yellow skins surround white flesh with a mild flavor similar to famously sweet Southern onion types, while this variety can perform farther north than many comparable onions.

Start ‘Texas 1015Y Supersweet’ indoors for transplanting or sow directly where conditions allow. Plant seeds about ¼ inch deep and space plants 12 to 18 inches apart. Grow in full sun. This cold-tolerant variety is also well suited to containers.

Ready to harvest in about 175 days, lift bulbs once they have reached full size and maturity and cure them before storage.

Sweet, mild, and substantial, ‘Texas 1015Y Supersweet’ is excellent for fresh slicing, salads, sandwiches, grilling, everyday cooking, and storage.

Very good germination

I would say these have about a 95% germination rate. They have sprouted and are growing.

An Annual Favorite!

I plant these after the last freeze in late winter/ early spring, spacing them 2 inches apart and 1/4 inch deep. As they reach the 1/2 inch diameter size, I pull every other one for spacing (and of course munching). It’s our all time favorite onion down here!

Good germination rate

I planted these in October. I would say 95% of them germinated. They are now growing wonderfully. Some of them are about 3/4" round. Onions take a long time to grow, so i pleased with their progress so far. This is by far the best brand of seeds I've ever purchased.
