What causes leaves to turn yellow in Lilies?

Flowers from bulbs, rhizomes, tubers and corms (e.g. iris, alstro, lilies, tulips, anemones, freesia, lily of the valley, ranuculas…) stress out when the blooms are cut from the “bulb”.  Harvest causes an imbalance in cell functions. Symptoms are premature yellow foliage, short vase life, buds not opening and loss of color vibrancy. Chrysal Bulb t-bag to the rescue! Bulb T-bags rebalance the chemistry and eliminates the problem.

Should the leaves of Alstroemerias and Lilies be stripped almost to the bloom? 

Leave the leaves in place. The notion of stripping alstroemeria and lily leaves became popular 30 years ago BEFORE there were good post harvest options for bulbous blooms. Because foliage of “bulbous” flowers suffer a chemical imbalance at harvest which results in leaves turning prematurely yellow, florists started stripping stems.

Why not strip?  The leaves of any flower are a source of energy. Nutrients in leaves prolong vase-life and bloom opening. In many flower species, (e.g. roses) leaves are the pumps to pull water up the stem.

Is water falling on rose petals the cause of drooped over heads?

Drooping  flower heads indicates something is blocking flow in stems (generally bacteria and/or air bubbles). The cells under the flower head are the most immature and cannot support a bloom if they are not turgid.

Dripping water on flower petals is another problem altogether. Wet petals can aggravate Botrytis  potential (fungus disease).
