How do I get my Day Lillies to come up?

I found an article that said...

Daylilies can be planted at any time during the growing season when the soil is workable. If you are planting bare root daylilies, remember that those planted in the spring will provide only moderate bloom the first summer but will bloom at full strength in subsequent years.

I am not sure if you dug up day lilies and transplanted them or if you planted new plants. Daylilies are usually very hardy. If you transplanted some perhaps you didn't get enough of the roots/crown. They should come up this spring. Here's some planting information: https://www.wikihow.com/Plant-Daylilies

Give them a chance to come up after winter subsides. Maybe planted too deep dig them up to see if they are still there or if they rotted. Replant not so deep. Are they in full sun? They need full sun. There are many many varieties of Daylilies & they grow bloom at different rates & times of year. Are you sure they were Daylilies/tubers(clumps of roots) or were they Lilies/bulbs?? if bulbs/Lilies most due best planted in fall need to go thru cold spell. They will probably come up this year. Where did you get them many reputable companies have 1 year money back guarantee beause that is how long some plants need to grow well,get established.
