Radishes getting ripe

In Osaka we have 4 straight rainy days this week. I'm fed up with my clothes getting mud in working in my garden through the rainy days.

Although a half of radish seeds have not germinate the other half of them are getting ripe with their red roots on the surface on soil.

I'm not satisfied with this unsuccessful germination and I'm seeking a cause of that. Maybe I guess too much fertilizer on soil delay or interfere the germination. If you have some ideas and experiences of unsuccessful germination, please tell me on my blog.

Red roots of radishes can make my garden much colorful even if they are very small since all current vegetables in my garden are green.
