Drought Resistant Tree Care
Most well-established trees can tolerate some drought. Much depends on the drought resistance of certain species and whether they are growing on an appropriate site. Moisture sensitive tree species like dogwoods, Japanese maples, flowering cherries, and birches may need extra water in times of drought. Oaks, red maples, tulip poplars, sycamores, crabapples, hawthorns, elms, gingkos, and hackberries are noted for their drought resistance so should be a preferred species to plant in drought-prone areas.

I am responding to an article named: “Drought resistant tree care” I am pretty sure that Tulip trees are very sensitive to drought. They yellow when drought like conditions are present.
Hi Felicia!
All trees are sensitive to drought, but some adapt better than others. You can put dogwood in the unadaptive sensitive category, tulip trees in the adaptive.
The yellow-poplar (tulip tree), like other drought tolerant trees, sense water deprivation and drop leaves. This saves them from dehydration. Others hold their leaves, struggle and die.
