I planted 80 crocuses last year and only a few have come up?

Is this normal - maybe it takes a couple of years for them to come up? Should I have added compost into the hole when planting them?

Maybe it's just still a bit early for them.
Reply:I am guessing that you may have squirrels in your neighbourhood who might have eaten them last fall and during the winter...OR do you by chance have wild rabbits? One year I waited and waited and finally went out and dug around only to find my crocuses were being mowed down every night by the bunnies.
Reply:If the ones that are up bloom without seeing any others emerge, my guess is that some *critters* got a hold of the others...chipmunks, moles and squirrels love them and I've also had deer paw them up to eat when their normal food sources are scarce in the winter.
Reply:depending on temps where you are it may be too early for them to come up. if not, many rodents love the taste of these. as far as planting them, rule of them is 3 times the heighth of the bulb, which works for about 99 percent of bulbs. unless your soil was very bad, compost wouldnt be needed.
Reply:What zone do you live in? Crocuses do best where the winters are fairly cold. Make sure the area is well drained or the bulbs may rot.
