We never want to see our plants wilt. It’s drastic, it’s dramatic, and it feels like they are at death’s door. And while they most certainly can be, all is not lost. Wilting is a common life strategy by plants. A physiological response to losing more water than they can replace.
In this article, we’ll look at the causes of wilting, plus we’ll bring a couple of plants back from the brink to show you just how reversible it is if caught early enough!
What is wilting?
Wilting also known as flagging is an extreme life strategy by plants to conserve moisture when the rate of transpiration by the leaves exceeds that of the water intake of the roots.
What does wilting look like?
In leaves, flowers, and fruit, rings and spots (often zoned) in colors like brown, purple, pale green, red, yellow, or white develop. Stems and petioles may acquire long stripes. The leaves may get deformed, speckled, or become bronze or yellow.
Why do plants wilt?
The plants are dehydrated they’re using up more water than they can take in which makes wilting a physiological response.
This lack of water can happen for several reasons the most obvious being drought in extreme heat but it can also be brought on by damaged roots, poor soil, and high salinity.
What happens when a plant is wilting?
The plant starts to wilt as a result of the collapsing, dehydrated cells in the leaves and stems being unable to stand upright. Interestingly, wilting prevents water loss by exposing less of the leaf’s surface to the sun’s evaporative rays as a result of the drooping leaves.
Can wilting be fixed?
Fortunately when caught early enough wilting is easily reversed. Solve the problem causing the moisture imbalance in this case drought and the plant bounces right back looking no worse for the wear.
Make no mistake however wilting is not ideal. It’s an extreme physiological response to a lack of water. But for us growers it’s a highly useful visual indicator that our plants need something from us. It’s their way of telling us that something isn’t quite right.
How long does it take for a plant to recover from wilting?
If your plant is withering, try watering it and watch to see if it recovers. Sometimes, things are just that simple. When plants require watering, their leaves usually start to wilt. The leaves will rehydrate within a few hours if they haven’t already turned crunchy.
FAQs on wilting of plants
Does wilting mean too much water?
Plants wilt and their leaves turn brown when they receive insufficient water. Additionally, this happens if plants receive too much water. The primary distinction between the two is that while too much water results in soft, limp leaves, insufficient water causes your plant’s leaves to feel dry and crispy to the touch.
Do plants wilt in the heat?
A plant under heat stress will typically wilt, which is a strong sign that water loss has occurred. If this goes unattended, the situation will get worse because the plants will eventually start to dry out and turn crispy brown before passing away. Yellowing of the foliage may take place occasionally.
What is the common cause of temporary wilting of plants at noon?
Wilting can also happen when there is enough water present but the temperature is excessive, such as during noon, on a hot day, or when there is a strong wind. This is due to a process called transpiration, which causes plants to lose stored water through their stomata.
Why do plants wilt after transplanting?
Transplant shock occurs when a plant is transferred outside and exposed to the elements, signaling the activation of its defense mechanisms. It shows itself as wilting, yellowing, curling, and even death of the leaves. The roots will go to whatever lengths to ensure their own survival and order the plant to rest and use less energy.
Why do plants wilt after rain?
Despite perhaps high soil moisture levels, excessive rain might deplete the soil’s oxygen and suffocate roots. Check your plants after the rain to determine whether they are wilting or have scorched leaves. This is typical during warm weather.
In which soil will plants wilt the quickest?
Plant wilting is by far most frequently caused by dry soil.
