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.

A better suggestion is a Styrofoam box used for corn or zucchini - if you can find bigger boxes the better - you can grow more at a time. Go to Foodworks, IGA or any supermarket and ask if they have any. Put newspaper, shade cloth or bubble wrap on the bottom - then about 25 mm of small pebble (the beach) - then another layer of paper, shade cloth or bubble wrap with some holes in it. Mix up some soil, sand, compost/manure and potting mix/seed raising mix. Put that in the box and give a good watering. Plant the radish and sprinkle some soil/ potting mix/seed raising mix over the radish. Keep out of the sun until they germinate or put some shade cloth or something similar over them until they germinate. With this free draining soil and shallow soil depth they will need watering each day and plenty of sun. Have 2-3-4 boxes and have a succession of plantings. This method can be also used to grow lettuce and baby spinach - plant very densely and cut the young leaves about 25-50 mm up the plant and they will reshoot - multiply cuttings. You can buy seeds on the internet 100-200 seeds for $1.
