    If planted out too early they may be rotting off/ killed by frosts.
    My problem is usually slugs. As soon as shoots immerge the slugs get them, weakening the plants.

    If you want guaranteed shape, colour and height, you need to buy named varieties, and crannman, are you splitting the tuber up before planting, if so not all parts of the tuber have growing points (eyes) plus as Norfolkgray says they cannot be exposed to frost, try starting them off in pots so that you can protect from frost and snails and plant out after the last frost

    it may be a struggle to reach the top, but once your over the hill your problems start.

    ^^^^No they are actually easy to grow from seeds you can't always guarantee the flower colour as most seed packets are mixed

    I've bought quite a few mini plants from halls of heddon. They seem a bit dearer this year - looks like about 3 each and 7 for a delivery but they always arrive as well rooted cuttings and grow well. No failures yet. I pot up in greenhouse till I'm ready to plant them out.

    I put about 35 different roots in a shed to store over winter about a week back - not all from Halls but a lot were as well as some chrysanths.

    try spreading the tuber out on a seed tray filled with damp compost keep frost free and once you see some shoots on them plant into a suitable size pot grow on and once all frost has finished harden off before planting out
