The first step in saving your overwatered plants is to determine how badly they have been affected. If your plants are showing some yellowing but have not yet started to wilt, you can save them by beginning to water them properly. If wilting has started to occur, you will need to work harder in order to save them.
1. If a plant is overwatered, it will likely develop yellow or brown limp, droopy leaves as opposed to dry, crispy leaves (which are a sign of too little water). Wilting leaves combined with wet soil usually mean that root rot has set in and the roots can no longer absorb water.
Stop Watering the Plant
But stopping your watering is always the first step. If you're overwatering, you'll likely notice that the soil is wet, so you want to make sure that soil is bone dry before you're ready to break out the watering can again.
Signs of root rot are slow growth, mushy stems, and wilting, yellow, distorted leaves (especially when the plant has been well watered, as wilting leaves can also be a sign of a dry plant).
Look out for signs of overwatering – including a limp plant, yellowing leaves, or dropping leaves. If you see these signs, test the soil with your fingers. It should be pretty obvious if it's soggy! Stop watering and let the soil dry out.
One of the quickest, first signs of overwatering your plants is to observe occurs at the tip of the leaf. If the tip of the leaf is turning brown this is a sign of overwatering. Too little water will result in your plant's leaves feeling dry and crispy to the touch while too much water results in soft and limp leaves.
If overwatering is the issue, the roots will look dark and feel mushy to the touch. The plant's soil may also give off a sour, funky smell, due to water-loving bacteria forming around those roots.
You can do the ball test to see if the time is right. Dig some soil and form a tight little ball in your hands. Press your fingers into it. If it stays together it's too wet.
The good news is that most plants will bounce back between 7-14 days if they're given proper care (which includes rehydration). If this isn't possible because major damage was done or little healthy root system exists then expect about 2 weeks until improvement can be seen.
Using a hairdryer directly on the soil is an easy way of removing that excess moisture easily. However, there are some things to take into consideration when doing so. When directed at the soil the dryer will only remove the moisture from the surface having the rest of the soil wet.
Leaves begin to wilt and turn yellow or fall off, growth slows, and blooming may be delayed. In the most extreme cases, when conditions are ideal for the fungus to spread quickly, plants can die within 10 days.
A yellow leaf has lost its chlorophyll (pigment) and it can't turn green again even after you correct the problem. Don't worry, if the plant regains its health, it's possible that new leaves will fill in during the next growing season. Growing plants is always a matter of patience.
Symptoms of overwatering indoor plants
The primary symptom of excess moisture is wilting or yellowing of lower and inner leaves. If excess water continues, plants may show other drought symptoms, such as scorch, leaf drop, and/ or plant death.
Determine which by feeling the leaf showing browning: if it feels crispy and light, it is underwatered. If it feels soft and limp, it is overwatered. Yellowing leaves: Usually accompanied by new growth falling, yellow leaves are an indication of overwatering.
Increases in the rate of leaves senescence and drooping, scorching and limp leaves, leaf rolling and brittleness, closed flowers and flower sagging, etiolation, wilting, turgidity, premature fall, senescence and yellowing of leaves are among the most ubiquitous symptoms of drought stress in plants [65,66].
As for the leaves that still have brown tips, you can snip the dead parts away with a pair of scissors without hurting the plant. For some plants that have long, strap-like foliage, such as dracaena or spider plant, make your cuts at an angle to imitate the natural shape of the leaves.
Make a habit of checking on your houseplants at least once a week to see if they need a drink. The best way to tell if your plants need water is to stick your finger about an inch into the potting mix—if it feels dry, break out the watering can. If you detect dampness, check back again in a day or two.
Q. How often should plants be watered? Water once or twice per week, using enough water to moisten the soil to a depth of about 6 inches each time.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
