The packet suggests sowing the seeds two to a pot.Is this necessary? Or can they be sown straight into the ground. Will the flowers be bigger and stronger if pot sown?

    I have never direct sown but yes if you do decide to do in pots then I always do two per pot just in case one fails 😊

    Or you could sow them into a seed tray and then transplant into another seed tray when they have 2 real leaves.

    I sow into plug trays as individuals, then pot into 7 cm pots, then pinch out and pot into 6 inch pots. That gives good strong plants ready to romp away in June.

    Than you so much for your replies. Probably best not to just scatter around on the ground then?!!!!  😁🌱🌱🌱

    Sounds like the voice of experience...i'm going with this!

    I always know the season has started when Cosmos gets a mention. I sowed Cosmos Cranberries and Xanthos on Saturday and they are off the heat already. Exciting times! I will pot them on that way too.

    I usually sow cosmos in seed trays and then pot up individually into 9cm pots.  When potting up I plant the seedlings deeper than they were in the seed tray and the stalk under the soil will grow roots which seems to make a better plant.

    I’ll be sowing mine next week, this year I have a propagator with grow lights which so far is proving to be of great use.

    About to sow mine today .....love Cosmos.  This year I’ve got rubenza, purity and a selection of the pink/white picotee ones.

    i sow in a seed tray and then prick out in a few weeks.  Like Magpie maiden, that gives me a chance to bury any leggy seedlings 🌱
