hard to grow

1 out of 5 stars Jan 24, 2022
I tried growing these seeds in my bucket garden with no success. Any radish that grew was really just too hard to eat.

Owner Response: Hi Ruth, We are sorry you didn't like this radish. From your description, it sounds like they were overly mature and tough. It sounds as though the seeds germinated so the growing issues would be related to environmental conditions. Radishes need cool conditions to grow well whereas warm temperatures lead plants to bolt (flower) and become tough. It is worth thinking about the growing media too, which, of course, will impact the plant's success. For instance, an excess of nitrogen will promote leafy growth over root growth.

I loved these radishes, best radish I have ever had. I planted them in a container garden and they grew quickly and were mild, yet spicy at the same time. Delicious. Doubled my order this year.
