Do not remove the foliage, as it needs to turn a straw color and die back before you can lift your tulip bulbs for saving. Once the foliage is spent, dig up your bulbs and shake off any excess soil.
The reduction of chlorophyll production in leaves due to decreased sunlight in the autumn explains why some leaves turn yellow.

Deciduous trees experience much less branch and trunk breakage from glaze ice storms when leafless, and plants can reduce water loss due to the reduction in availability of liquid water during cold winter days. [16] Losing leaves in winter may reduce damage from insects; repairing leaves and keeping them functional may be more costly than just ...
A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When abundant in the leaf's cells, as during the growing season, the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf. Thus, the leaves of summer ...
