I planted red lettuce on a high bedding, I water always, but I see no growth. Don know what I am doing wrong. I live in florida, temperature is on 60 in the morning , 80 middle day. Thank you.
Did the seeds germinate and begin growing, but then die? In that case, overwatering could be the problem. Once they start to grow, seedlings should be watered less (though they shouldn't dry out entirely) to prevent a disease called damping off:
If that's not the problem, you could have excessive salt in the water or soil, or toxins in the soil. This is likely if nothing else will grow in the spot either.
