Damping Off: The death of seedlings by either over watering or disease or a combination of both.
Dead Heading: Cutting off dead or dying flowers to encourage further blooms by preventing the setting of seeds.
Damping off
Seedlings started off so early in the year are especially vulnerable to the fungal disease damping off, which causes seedlings and young plants to collapse at soil level.

Instead of fussing with grow lights, damping off potions, calendars, and dry indoor environments, the winter sower is occasionally adding a bit of water to containers that have dried out or re-anchoring lids that have started to blow off.
In the germination phase, impatiens is prone to damping off, so plant plenty of extra seeds in case this happens.
When the stems of young seedlings become withered and topple over, they have probably been killed by a soil-borne fungus called "damping off.
Use sand or vermiculite to very lightly cover seed and don't over water as they are prone to damping off. Seed should germinate after about one month.
Fan: Good ventilation helps prevent damping off and other fungal diseases prone to attack seedlings. "Plus," says Owen, "ventilation helps them breathe by circulating carbon dioxide and oxygen.
Chamomile tea sprays can help prevent damping off, a condition that causes the plant to fall over. Check the stem at soil level. If it is withered, that's "damping off." Remove the plant. Do not over water.
Wet clay soil can cause damping off and rot, and it dries into a hard-baked crust. The ideal soil is garden loam with about equal parts sand, clay, and humus, which provides nutrients for beneficial micro-organisms in the soil.

However, late hot temperatures such as we experienced this year can cause poor germination rates, and seedling diseases such as damping off can be higher in high soil temperatures.
seedlings, tomatoes that are raised in this manner are vulnerable to damping off
disease. This causes the seedlings to rot at the base of the stem and collapse. The
routine use of a fungicidal treatment is to be recommended.
By sowing in rows, good light and air movement results and, if damping off fungus appears, there is less chance of it spreading. Sow the seeds thinly and uniformly in the rows by gently tapping the packet of seed as it is moved along the row.
To avoid crown rot or damping off, top off the seed mix with 1/2 inch of sharp sand or vermiculite; this keeps vulnerable young sprouting stems from rotting off due to excess moisture at the soil surface.
