Here in Central Texas,
zone 8, near Austin I have grown these beautiful
flowers for a decade at least. As noted above, if you plan to grow them indoors and buy them in a pre-packaged gift box then all you need to do is water it initially and watch it grow. However, I like to grow them outside! Once finished, I wait for the leaves to turn yellow, cut them off about two inches above the nose of the bulb and put them in an extra refrigerator we have in the garage, the crisper to be exact. After 6 weeks or more I
plant them outside in a spot I have reserved for them. After that I leave them alone except to feed them twice a month with Super Bloom. I occassionally have tried Super-Phosphate or Triple Phosphate to see if there is any benefit to the
flowers themselves. I leave them planted all year long only to remove spent leaves and they do great, coming back year after year. This won't work in all
zones but it's worth trying as an experiment. The bulbs here only cost $2.50 each so a loss of one isn't going to hurt anyone. The rewards are incredible! I have neighbors walking down the street come up to me outside and ask me "What on earth are those beautiful
flowers?", and "Where can I get some of those?" I just love that! Hope this helps.
