You may want to do a soil test so you know what you have and what you don't. Using all that potting soil you may need some lime mix in there. If your organic is right out of the bag and not aged you just have to wait several yeas before it's broken down well.

Hello, I have been growing vegetables here in Manteo, NC for the last 10 years, zone 8b. I believe your planting times are at least 30 days too early . I plant most of it by seed outdoors maybe and that may be the reason.

Read the paragraph at the bottom of the page. It is general advice, There could be many different sub climates within the same climate. Generally it is about soil temperature required for germination.

I had no idea you could actually eat the green end of a radish until i started gardening myself this past year. doing research on the when and hows has taught me so much and the green end of the radish was actually really good! Great flavor! thank you for gardeners and gardening! So much peace in my life now!!

Hint: Radish leaves can be used as a stir fry green.

I always grow radish but often let them get too fibrey. I let some go to seed, amd found my sugarbag bees loved them. I then let them go to seed and found the young, tender seed pods are tastier than the radish itself, and you get far more output as they seed like crazy. Pickling the pods also works well, so now I grow them for the seed pods, and the bees. I recommend trying it

Pick your radish when they have grown to the right size and put them down in the veggie section of fridge - they will keep for weeks. They are more a late autumn winter early spring crop in sub tropics.

My radishes came out too small or not developed a full bulb/root at all. I used a peat based potting soil and compost + vermiculite also amended with fish/kelp emulsion. I am growing them in 6 inch deep flats with proper drainage holes. The variety is Cherry Belles, Rover, French Breakfast. Planted them in late summer for fall.
