no i haven’t had too much success with radishes until this year
i dig the soil probably 6 inches deep, put some plant tone and diatomaceous earth in the bottom probably around 1/2 cup per square foot at a 2:1 ratio. amend some recycled potting soil with existing soil probably at about 1/3 recycled potting soil to 2/3 soil in the ground which is usually clay. i then put about 3 seeds in each hole. at about 1 inch to 2 inch deep. if you dont plant radish seeds deep enough they never form a large taproot. i then thin to about one per initial seed hole using scissors to snip the ones i want to get rid of as not to disturb the taproot of the one i want to keep. i wait about 1 month and topdress with a 1/4 cup of plant tone and diatomaceous earth 2:1 ratio and water in real good. then i wait another 2 weeks and thin the ones that haven’t really taken off, by that point it is safe to sit back and relax a while as the ones you have left will stay good until it gets severely cold probably around 25 and i would pick before it gets that cold. but some radishes can take the cold and can be left longer it all depends on when you want to harvest.
this has been my best year and i can say that the greens are better than the radishes. they are the best greens of any greens i grow that is meant for further preperation. I like to eat lettuce fresh and cabbage fresh.
keep em watered and you can grow them at about one inch spacing from each other
i too haven’t had good success with carrots but i think in my area they prefer to be planted in spring and not fall. we will see next year. beets however do much better in spring than fall around here and im guessing they need alot less nitrogen
