Excess fertilizer salts may form a white crust on plant containers or soil and cause wilting. Run water through the soil to leach out excess salts, or repot a container plant in new soil.

Lack of Water Plants need water for nutrient transport, growth and structure.
Soil Conditions Poorly drained, heavy or waterlogged soil deprives roots of oxygen and indirectly causes wilting. Disease Some plant diseases can cause wilting. Pests Aphids and scales are examples of insect pests that cause wilting. Established landscape plants and mature trees can extract this water and maintain their water needs without needing any additional rain or irrigation for seven to 10 days.
Newly planted trees and shrubs may need supplemental water more often for the first couple of years until their roots grow deep enough to seek out water in the subsoil. Let the plants tell you when they need water. Even new trees and shrubs can go a couple of days without being watered. When you do water, soak the soil deeply to encourage deeper rooting — this will pay off in the long run as the plant acclimates to its new environment and is able to take care of itself for extended periods of time without rain.
Adding a few inches of mulch around trees and shrubs will conserve soil moisture and help reduce extreme temperatures and drying of surface roots. Permanent wilt may happen if plants remain wilted even after you water them. There are certain soilborne diseases — such as Fusarium wilt, bacterial wilt, and Phytophthora — that can infect the stems or roots of plants and literally stop the flow of water.
This is a common problem in vegetables like tomatoes and certain landscape plants such as rhododendrons. The plants might start out with one or two branches that wilt and then eventually the entire plant wilts. If a plant is wilting with no apparent cause, it might be worth it to send a soil sample to a lab for verticillium wilt testing. Once the disease is identified, reduce its presence by rotating with crops that do not host the disease, including corn, wheat, barley and broccoli.
