Wilting leaves can signal a number of problems.
The joy of carefully tending garden plants throughout spring and summer can quickly turn to frustration and dismay as the vines, leaves and branches start to wilt during harvest. This problem is not uncommon, as plants struggle to survive the stress of heat and producing fruit. It is, however, preventable with a little knowledge. Does this Spark an idea?
Root Rot
Root rot destroys the roots of a plant, preventing it from taking up enough water and nutrients to sustain itself. Although this process can happen quickly, it often takes time, and by the end of a growing season the damage will be severe enough that symptoms will begin to appear. The first symptom is usually wilting leaves. Root rot can be caused by a number of different organisms. Plants in poorly drained soil are especially susceptible. Late summer rains and over-watering can lead to root rot. If possible, reduce the amount of water the plant is receiving. Apply a fungicide to the soil and remove any mulch to allow the soil to dry out.
Weak Roots
Improper watering methods over the course of a growing season can lead to a weak root system. As summer heat wears on and the plant becomes stressed, the roots are not able to carry enough moisture to sustain the plant. Production of fruit takes additional nutrients and energy from the plant. It eventually begins to wilt due to lack of moisture and nutrients. Weak root systems can be prevented by watering less often, but watering deeply so that the roots grow downward into the soil to collect the water, rather than staying at the surface.
Verticillium Wilt
Verticillium wilt is a fungus that attacks nearly all types of plants, including garden vegetables. It is especially active during hot weather and at harvest time. The fungal infection causes the leaves to turn yellow and wilt, often curling up and falling off the plant. Then entire sections of the plant begin to wilt and die.
Damage
Damage to the plant during harvest can also cause it to wilt. If a plant is not securely rooted in the ground, the tugging and pulling of fruit can dislodge some of the roots and expose them to the harsh sun. The plant is not be able to absorb as much moisture as needed and will wilt. Broken stems or branches during harvest can also invite diseases that cause wilting, or cause a portion of the plant to die. Cut fruit away with sharp shears and take care not to pull or place strain on the plant.
