Q.Cosmos Seeds Indoors

Anonymous added on March 14, 2014 | Answered

I’ve sown some Cosmos seeds in trays that have come up very tall and thin (spindly). Is this normal and will they fill out eventually?

They have too little light. They need either a brighter window or you need to get a fluorescent bulb and place that a few inches above the seedlings.
