How to grow radish in summer heat

[Marb67]

I. Have posted in the past at my woes on failing to grow radish as they bolt, produce small woody roots or no roots at all that swell. Despite keeping them in a cool part of the garden with watering when required. I heard from an expert that we should be sowing them all through the season little and often.

The question is how do you do that without bolting ? I can only grow in containers as no space in the soil. Slugs would also eat them as they emerge.

I've never had much luck with radishes in summer either. I found if I keep them in the shade stop them ever getting dry I could get some small ones, but leave them too long (1 month) and they go to seed.

Something worth trying is a radish pod variety like munchen bier, they have large roots and go to flower pretty quickly, however when do they really got nuts.
One plant will give hundreds (if not thousands) of radish pods, I planned 4 in flower buckets last year and was eating them in most meals and still had far too many July.
You can use radish pods as you would normal radishes and they will keep cropping until winter hits. I was still getting fresh pods (they are nice pickled) in November last year.

I use 4 Morrison's flower buckets cut down to about 6" deep when the tops have split.

30 odd 3" Breakfast per pot, as one finishes it is resown, I find this keeps us in nice fresh radish throughout the season. The only tip I can think of is give them plenty of water and never let the compost dry out.

I always keep the compost moist and never let dry out but they still are poor or bolt.

Someone here said that as they're Brassicas treat them like cabbages by making sure the ground is firm and firming them in well, perhaps even use a little lime? I'm going to try it anyway....

I do use fresh or riddled/refreshed compost every time. Set the seed in circles with about an inch between them, cover with 1/2" compost and water. When I say give them plenty of water I suppose I am lucky they sit on the side of my pond. Therefore when the plants are strong enough I just submerge the container in the pond for a couple of minutes.

All I can say is 'it works for me'.
