Small, spicy tasting root vegetable usually round but some longer varieties . Available in a range of colours between red and white.

Very easy to grow. Good for a child's first garden as seedlings appear in two or three days. Sow between other vegetables as they will mark the rows until the slower germinating plants appear.

My radishes grow all top but no bulb. Any ideas.

Hey Danny, me too! I thought I hadn't planted the seeds deep enough or firmed down the soil hard enough after planting seeds? Will be giving these a go next lot as mine are also growing more above ground than below.... hope these ideas help!

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?
