I tried to plant some fall carrots direct sowing them into a large planter. I planted 150 over 2 weeks ago and have 4 tiny plants so far. I kept the soil slightly moist but not overly wet, planned about 1/4 - 1/2" below the soil. \n\nNot sure what went wrong other than maybe bad seeds? I'm going to try a few more from different seed packets. Is there some tick to carrots I'm missing?
