Question
Hello I Live in the High desert in southern california (U.S)and i recently planted cucumbers,watermelon,corn,tomatoes,canteloup,pumpkin,and carrots in small containers. At least 3 to 4 seeds are placed in each "hole". now they are begining to sprout but now all of them are dying. Im using good fertilizers and proper watering. But still, they are dying. This past week the temperature has been at a constant 100-103 F and the small seed starter containers are placed in full, direct sunlight. maybe the heat? why are my plants dying? Thanks!

Answer
Too hot. Until the roots can get down into the soil where it is in the moist cool earth, they frying and dying before it has a chance.
I can only recommend that you plant in the cool of the spring, so that they are up, and growing before it gets into the 100s.
