It is no wonder that 'Mantanghong' is the most popular of the Chinese "beauty heart" radishes. This summer/fall-sown radish produces large, 3" round, mild radishes that can weigh up to 1 pound each! Slice the greenish white exterior to reveal a vivid, fuchsia interior. Whether you enjoy radishes raw, cooked, or pickled, these beauties are sure to be a star. Winter radishes are best sown in the late summer or fall, as short days trigger root growth.

Watermelon Radish seeds (Mantanghong)

5 out of 5 stars Jan 16, 2020
I found watermelon radishes at my local co-op store and really liked them and wanted to grow them. After several months I finally found a packet of seeds and they grew for me. hoped to plant more to stagger the crop but could not find any more seeds. That's when I found Botanical Interests. and ordered Mantang Hong watermelon seeds. They worked wonderfully. I ordered more of those plus some other radish seeds that intrigued me. I put in a cold weather crop but unfortunately Minnesota had an early frost and destroyed that crop (I think - we'll see this spring if anything survived). So I still have seeds and look forward to planting them in the spring and seeing what other seeds pique my interest from Botanical Interests. They really turn your order around quickly.

Owner Response: Hi Pat, Thanks so much for the review. We just love watermelon radishes! I just wanted to remind you that watermelon radishes, daikon, and Spanish black radishes are "winter radishes" and only form a nice root in the waning light of late summer and fall, not in the spring. Since temperatures and light decrease in late summer and fall it is a good idea to add a couple more weeks to allow more time to mature. Happy Gardening!

I was thrilled at how well these did in my fall garden. They were my first radishes ever. I'm a big radish fan and enjoyed eating them. They had a bit of a spicy, radish flavor but not overwhelming. The color was neat! I was surprised at how large they grew. I can't wait to start more this fall.

I planted these radishes three times this year in my garden, this third planting (early September) are the only ones that are actually growing. Hopefully I can get a small crop from this sowing.

Owner Response: Hi Keri, These are winter radishes and will only grow as days get shorter. They are not recommended for spring planting. I hope that helps. There is some information on the seed packet if that is helpful also.

Last winter, 2022-2023, was the first time we grew this variety. The germination went well but the plants didn't develop from the seedling stage as quickly as we expected. I doubt this was due to the viability of your seeds or selected strain. Our lack of success was likely due to my lack of attention (it was only a radish after all).
