Hi Karen, it sounds like damping off, a common problem when germinating seedlings. If the seed raising mix is too rich in nitrogen or the seedlings have been fed a nitrogen rich (liquid) fertiliser then this can happen. Also, keeping the seedlings damp may have also contributed to the seedlings collapsing. Warmth is good, make sure the seedlings don't become too stretched and have plenty of light, reduce the watering and allow the surface of the seedraising mix or potting mix to dry out between watering's. If the seedlings are sitting in a tray or saucer of water, drain the water away so that the mix isn't constantly damp. Lianne.
