Tree lilies.

Last year I grew four Tree lily bulbs in a pot. They gave a fantastic show.  I bought fifteen new bulbs and planted them last Autumn in my raised beds.  They started to grow and looked very strong, however, when they were about nine inches high the frost killed them by wilting the stem in the middle.   I then bought another twelve tree lily bulbs and this time planted them in the garden.  Again the frost got them by wilting the stem.  I thought these lilies were hardy?.   Can I save the bulb, and how do I go about that.  This sudden cold snap also got my Hosta's.

    How deeply did you plant them in the garden ? 
  • Sorry AnniD,  Have only just seen your post.  As instructed, I planted them four times the depth of the bulbs.  They grew beautifully until that late frost.  As they were destroyed for this year I dug them up, placed them in a box and they seem happy in there.  They now have small growths coming out of the sides.

    They'll slowly wither and die in a box.  They need to be permanently in the ground and left, even if a late frost gets them.  Over time they will adapt and multiply if in a suitable spot.  Mine have 6 to 8 inches of soil above the top of the bulbs when planted.
    A trowel in the hand is worth a thousand lost under a bush.
