The seed germinates and appears healthy then suddenly wilts and die for no obvious reason. This sudden death is caused by fungi, soil and air temperatures above 68 degrees, and/or wet soil with high amounts of nitrogen fertilizer. Seeds do not need any fertilizer to sprout.  They need fertilizer after their true leaves emerge and their false first leaves die off. 

To avoid dampening off: keep the seedlings moist, but do not overwater; avoid overfertilizing your seedlings; thin out seedlings to avoid overcrowding; make sure the plants are getting good air circulation; use a sterile soiless growing medium with good drainage; and thoroughly wash all seed flats in soapy water & rinse in a bleach solution before reusing.  Good luck!

The issue is they shoot up so tall and the stems are so spindley, they can't support themselves so they keel over. How do  you get the sturdy stems that will support itself?

<![CDATA[Re: Help starting plants]]> http://www.burpee.com/community/discussion/721/help-starting-plants?commentid=2064 If your plants are elongated and weak, try setting a full spectrum grow light just 4" from the top most leaf just after germination.  Average post germination growing temperatures should be between 62 and 68 degrees F. Consider diluting your fertilizer to half strength until plants appear healthy again.

<![CDATA[Re: Help starting plants]]> http://www.burpee.com/community/discussion/721/help-starting-plants?commentid=2065 It sounds like like you may have several problems.. 1, Sanitation: sterilze all your planting containers using one part of clorox to 9 parts of water. Dip and let dry. 2. Use a sterile starting mix such as ProMix... no ferilzer. 3. In zone 5 I start marigolds about March 17-30 and Zinnia about April 20-30. 4. Use the mix damp not wet and place the container in a zip-lock bag until the seeds sprout and then remove the container from the bag. 3. Place the container 2 to 3 inches from florescent light about for 15-16 hours per day. Grolights are not necessary. Shop lights will do. If you put them in a window use a southern window. In either case rotate the containers every day and water carefully perferably from the bottom. No fertilzer until they get their second set of true leaves and then ferilize at 1/3 strenght about once  a week. When they get their second set of leaves transplant them to six packs or individual pots. Also try not to plant the seeds too thickly in the starter mix - close plants invite trouble.
