The most common cause of lots of leaves and small roots in radishes is an excess of manure which has a lot of nitrogen in it. Nitrogen is what causes leaf growth and is ideal for lettuces, spinach, etc. If you have used a lot of manure plant a leaf crop to use up some of the nitrogen then plant your radishes.All the best.

I have read that that can happen if you leave them in too long, could that have been the case?

I've found main pests tend to be grasshoppers and caterpillers. You can grow them with daikon radish in between. They have bigger leaves and grow more vigorously so tend to attract pests. They are also reported to be good for soil system in similar way to rocket. In Japan they grow them in the rows between orchards for soil quality and to suppress pests.

Does anyone know any pest and disease management strategies?

I am also using fresh radish with sushi instead of wasabi. Delicious!

I am wondering if you are able to make a paste like the horseradish paste you buy from the store but from the pink radishes as i have noticed that the flavour of my pink radish has a bite to it similar to that of the horseradish root. Meanwhile i will try to make it using my Grandmothers horseradish paste recipe and let you know how i go.
