I have 35 day lilies which I divide every couple of years.
My Lily Trees (18) have done very well and a few are large and need to be divided. One pushed out of the ground, in March,2017 and I was shocked at the size of the yellow bulb.
The 12/15 small babies surround the large bulb where placed in earth in house but none survived. The large bulb was placed back in garden - deeper than before and now is 2 feet tall where all the others are a good 5 feet.
Is there an online site that shows exactly how to divide after the blooming is complete.? (Picture is 1st year)
