Your crocosmia should certainly appear without too much trouble, this one grows like a weed, so unless you've done something really daft, like buried it six feet deep, it will appear, with or without your intervention, and certainly doesn't require special watering. Too much water could, in fact, rot the bulbs and corms. I'd just leave them alone and water as you would anything else - when the soil is dry which, where you are, it probably is right now. But even so, I'd only water once a week, unless you've got them all in pots and its very warm. Crocus here in west London get eaten almost immediately they're planted by squirrels, so I've stopped planting them, and your lilies may have succumbed very rapidly to lily beetle without your ever noticing they'd started growing.

My crocosmias are not up yet - a very few tiny points but that's all. I think the dryness might be holding them back. As for lillies, they are all up and between 3 and 6 inches tall now. Lillies are martyrs not only to lilly beetles but to slugs - I've got beer traps near all of mine and so far it's worked, but in previously years the first thing I've known about it is finding a chewed off stump where a lilly was meant to be!!
