Can your plant come back from root rot?
Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant. However, if some healthy, white, firm roots exist, try to bring the plant back to good health by replanting in fresh soil with good drainage.
What is causing root rot?
The cause of root rot is a fungus. Species of the Pythium, Phytophthora, Rhizoctonia, or Fusarium fungi are the usual culprits. These fungi thrive in wet soil, and you can transfer them from one part of the garden to another when you transplant ailing plants.

What root system does cotton have?
Cotton is one of the taproot crop, where the root system consists of tap root, lateral root, branch root, hair root and root hairs.

Should you stress cotton to grow deeper roots?
Severe stress reduces fiber quality through shorter staple and higher micronaire. At this growth stage, maximum rooting depth is achieved but lateral roots continue to grow throughout the rooting profile so that the final size of the root system may not be reached until 90 days after planting.
