Is your plant wilted even though the soil is wet? Is your plant light green and struggling? Well your problem might be over-watering. Read this article for tips on diagnosing an over-watering problem and than fixing it.

Did you know that over-watering is usually considered the most common cause of early plant death? In general, we are deathly afraid of under-watering our plants and as a result many of us tend to over-water. I am just as guilty of this as anyone else, although I am getting better. The best thing you can do to keep your plant healthy is to water it correctly.

How do you know if your plant is drowning? First, have you been watering only when the surface of the soil is dry to the touch? If you haven’t, it is possible your plant is staying too wet. For more information on proper watering for plants in pots read “Water Your Way to Happy Plants.” Second, is your plant looking light green and generally unhappy? One possible reason for this is over-watering. While both of these foliage indicators are symptoms of over-watering, the most common way someone figures out their plant is drowning is that the plant has wilted even though the soil is wet.

Why is over-watering so detrimental to plant health? Healthy roots are the foundation for healthy plants. Have you ever noticed that after you transplant a plant it will appear to sit there for a week or more before it starts growing? Well, it isn’t really just sitting there, it is establishing its root system. Once it has grown a substantial root system the plant starts putting its energy in growing a larger plant and more flowers.

Roots are important to a plant because they are its primary source of water and food and are also important for the uptake of oxygen. The roots of the plant take up water but they also need air to breathe. Over-watering, in simple terms, drowns your plant. Soil that is constantly wet won’t have enough air pockets and the roots can’t breathe. Roots that can’t breathe are stressed roots. Stressed humans are more prone to disease. Well, stressed plants are more prone to diseases too and one of the common forms of plant stress is unhealthy roots.  Over-watered plants are likely to get root diseases, primarily root rot. You probably won’t know your plant has gotten root rot until you notice that it is wilted, but the soil is still wet.

What exactly is root rot? There are several different fungi that cause root rot. The most common culprits are Pythium, Phytopthera, and Rhizoctonia. Healthy roots should be white and clean looking. Roots with root rot are brown, grey, black, slimy or non-existent. Over-watering also tends to rob your plants of proper nutrition. Either the roots are damaged and can’t absorb the fertilizer in the soil or the excess water has leached the fertilizer from the soil. Either way the plant doesn’t have access to the food it needs.

OK, you’ve gotten this far and you think it is possible that you have been over-watering your plants. Now what? If the plants are showing some yellowing and you know they have been watered too much, but they haven’t started to wilt while wet, simply start following proper watering techniques (Click Here) and your plant should bounce back. Hold off on any application of fertilizer until you see new growth. Then I would fertilize with a water soluble fertilizer the next 2 to 3 times you water (after you see new growth) to increase the fertility level. After this go back to fertilizing every 7 to 10 days.

However, if your plant has jumped into the deep end even though it can’t swim (your plants are wilting even though the soil is still wet), then the plant is in much bigger trouble. If one plant in a combination planter is wilting and the others look fine you might want to consider removing the wilting plant to help keep the disease from spreading further. Begin using proper watering techniques (Click Here). If the whole planter is wilting you will have to be more aggressive.

CPR for Drowning Plants

  1. Move the planter to a shady area, even if it is a full sun plant. The roots of your plant are unable to take up enough water to keep your plant hydrated. Plants in shaded locations will use less water. Once the roots are healthy move sun plants back to a sunny location.
  2. Be sure the pot is draining. If no drainage holes exists add some or repot the plant into a pot with drainage holes. Do not allow the pot to sit in water, this will keep the soil too wet.
  3. If possible, create additional air spaces around the root ball. One way of doing this is slowly tilt the pot to its side and then gently tap the container, the soil ball should now be loose within the container. Carefully re-stand the pot up when completed there should be small air pockets between the pot wall and around the soil ball. This will allow the soil to dry quicker and at the same time bring oxygen to the root zone.
  4. If the plant isn’t too large, repot into a different pot. Be sure to add new soil. This will give the roots nice, clean soil to grow into. If the plant is too large to be easily repotted go on to number 5.
  5. Begin watering only when the surface of the soil is dry to the touch. Do not allow the plant to get extremely dry, this additional shock could be enough to kill the plant. If the plant is wilting badly, you can mist or syringe the plant’s foliage with water which will prevent too much leaf scorch. Do not fertilize. With the roots in a delicate state it can be easy to burn the roots with fertilizer. Once the plant resumes active growth return to normal fertilization.
  6. Treating with a broad-spectrum fungicide can be helpful. Your local garden center should be able to help you choose one.
  7. If the plant is going to make it you should begin to see improvement in a week or so. Once the plant seems to be growing nicely move it into a sunnier location and begin fertilizing again.

Even if you take all of these steps there is no guarantee that your plant will bounce back. It partially depends on how badly the roots have been damaged. If you have a tendency to kill a plant with kindness and are composting more than are surviving you might look at changing your soil mix to a lighter, fluffier soil.  Make sure you have plenty of drainage holes in your containers.  If all else fails grow plants that like their feet in water. Plants like Cyperus, Alocasia, Colocasia, Acorus, and many others will thrive in containers that drain slowly. If you tend to keep plants on the wet side you might want to steer clear of plants that are more prone to problems from over-watering than most other plants.

I suspect that I may be overwatering my pothos. These plants are supposed to be easy to take care of, but every time that I water, about 3-4 days later, the leaves on part of the plant turn yellow and have to be taken off the plant. I typically water when the top soil is dry and dry to touch about one knuckle deep in soil. Also, there are holes in my pot, so i usually transfer it to my sink to drain and then place it back on its plate. The plant is in my hallway, away from direct sunlight. It's starting to look bare and I'm loosing hope. Help!!

You are on the right track, more than likely, when you link the potential issue to water.  Unfortunately, too much and too little have the same symptom as do several other things.  Rather than reinvent the wheel - I thought this article covered the potential issues quite nicely:

First, cut back on watering. If you can move it to a brighter area for the time being, that would be helpful. If it has a saucer, make sure that water is not sitting in the saucer. Do not water anymore until the soil dries out and the pot feels light when you lift it. Hopefully it should make it!

Will my plant die? I left it standing in water all night. I've drained it and dried out the pot and root ball as best I can. I love this plant!!!

It should be fine as long as it gets a chance to dry out now.
Overnight completely submersed should not kill the plant, but I wouldn't recommend it on a regular basis!
Happy Gardening!.

HI! My mom transplanted my HEALTHY habanero plant from the garden into a large pot (using the soil it was already in). My peppers are continuing to ripen, but the plant itself is very wilted. She gave it a good watering (grrr) when she transplanted, and I have not watered it since (it's been about 4-5 days). The top is dry, the soil underneath is damp, but not excessively. I should state that the structure of the plant seems firm (yet I do need to add support as it is getting top heavy) and healthy. The leaves, however are shriveld, yet green.

If you transplant a large plant this is almost certain to happen.  No matter how you try to get them all, a lot of roots almost certainly got left behind, so the plant is having a hard time keeping the whole plant supplied with water. As far as the plant is concerned the fruit and stems are more important than the leaves so the available water is going to them first.  You do want to make ABSOLUTELY certain that the pot doesn't dry out, so keep the soil constantly moist.  Given time it should recover, but by the time that happens it might be frost is on the way and the season is over.  Just keep it moist and give it time.

I accidentally let the sprinkler on overnight for the ferns and they seem to have already somewhat yellowed and wilted (but perhaps because of the water). Help what can I do?

There really isn't much you can do other than hold off from watering until the soil has dried sufficiently to need more water.  You might consider fetilizing the first time you water, as overwatering like this can really wash fertilizer out of the soil, leaving your plants searching for food.

Do you know what I should do for the garden plants that are drowning from excessive rainfall?

The only thing that I have found that helps garden plants being overwatered by mother nature is to get out in the garden, take your shovel and lift the plants up out of the soil a little. This creates a little pocket of air around the roots and allows the soil to dry out some and the roots as well. If your soil is so wet and soggy that everything just sinks back into the muck you need to find a way to get more drainage (raised bed?) or perlite or gravel into your garden bed. We live south of Houston and have a lot of clay in our soil so I have been out in the garden during or after a deluge doing exactly what I suggested with my shovel in hand in 4 to 6 inches of muck and mud lifting my tomatoes and peppers out of the muck. We do have a raised bed but haven't found the right clay/soil mix yet to keep the soil from draining well during downpours yet allowing enough moisture to stay in the soil for 3-4 days during the hot summer months if it drains quickly. I have a 2' raised bed with weed stop sheeting on the bottom ,then a layer of gravel and sand about 3" thick then a mixture of composted leaves and plant matter mixed with regular clay soil. Looks like I either need to go up higher next year or add more sand/gravel to the mix. Hope this helps.

There really isn't much you can do for them.  While we can somewhat control water in containers, doing so in garden beds isn't really possible.  Excessive rain can be problematic, unfortunately that is just what happens sometimes.

Thanks for all the tips/advice. I guess l need to repot my flowers & speak life into them. They'll live.

I was hoping someone would have a good idea to save garden plants that are drowning from excessive rainfall?

Not only are the plants flooding but so our town....
