Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.

Cactus corking
Cactus corking is a natural aging process where the base of the plant turns brown, tough, and bark-like. While it is often a sign of a healthy, maturing plant, it can also be triggered by environmental stress such as improper lighting, physical injury, or sudden changes in temperature. Unlike rot, corked areas are firm to the touch and do not spread rapidly or smell.

Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
