Too Little Water Most plants do not exhibit dramatic responses to too little water. Instead, growth slows. The foliage may wilt, and brown leaf tips may develop.
Lower leaves turn yellow and fall off.
The surface of the growing medium shrinks away from the growing container, leading to deterioration of the fine root system. While most plants prefer a short dry period in between waterings, some require even moisture in the root zone to survive. Color may be lost and leaves may fall if this requirement is not met. As a rule, plants that receive too much water cease forming new leaves. The most recently formed leaves turn dark green, with the margins turning tan and cracking.
