The listing, Daikon Radish SEEDS can replenish poor soil has ended.
I've been testing this theory out that within four years of letting Daikon Radishes grow and go to seed, that bad soil will become fertile. If you'd like to give this a try, I will mail you a bunch of seeds to plant in some nonproductive soil and test for yourself. The plants get pretty white or pink small flowers with lots of seeds each year.The seeds are small and round. If you find aphids on your plants, clip and throw away anything with aphids and put banana peels under the plants.
