Is Overwatering Worse Than Underwatering? Overwatering is much worse for plants and has a much greater chance of resulting in the plant dying. Overwatering causes much more extensive root damage, which often must be treated by pruning off the affected roots and repotting the plant.
Overwatering causes plants to drown from lack of oxygen, or suffer from root rot and fungus because they can't dry out properly. Sometimes, however, in our attempts to avoid overwatering, we end up overcompensating and not giving our plants enough water. Underwatering is equally detrimental to your plants' health.
There are specific signs that will tell you your lawn is being overwatered. Overwatering your lawn is actually worse than under-watering because it will cause more damage. An under-watered lawn will struggle and die, while an overwatered lawn will not only kill off your lawn, but can also ruin the soils underneath.
Browning edges can indicate too much water. A plant pushes water through to the edge of its leaves, and if given in excess, this can cause veins at the edges to burst, which leads to browning. Wilting can go both ways, plants wilt when they're thirsty and when they're overwatered.
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.
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).
The symptoms of waterlogging are similar to symptoms of drought. If you have been watering your plant but it is wilting, drooping, yellowing, and has black or brown roots, the soil is likely waterlogged.
Wilting. The most apparent manifestation of insufficient irrigation in plants is general wilting. Water pressure inside the individual cells cannot exert force to maintain the turgidity, which causes them to droop. Yellowing and browning.
When plants are under watered, they can usually recover within a few hours after receiving water. If they are overwatered, this can cause roots to rot, and the recovery process will take much longer. If the plant leaves are wilting and still soft, they will likely recover after watering.
If your plants are in the ground (versus a pot), the general rule is that plants need one inch of water per week. However, this does NOT mean watering one time per week. That doesn't usually do the job. Plants do best when watered deeply about three times a week, factoring in the rain.
Poor drainage or improper watering
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.
Bottom watering is okay for smaller 4–6-inch plants, but we don't recommend this for larger plants. The time it would take to soak the roots in a larger potted container and get the full capillary action to the top of the soil may be too long.
DON'T Let Indoor Plants Sit in Water
Soaking the soil is important, but don't go overboard and add too much – if houseplants sit in water, they can develop root rot. If you accidentally overwater, use a turkey baster to remove the excess. Need more tips on how to keep houseplants alive and healthy?
Types of Plants You Can Bottom Water
Provided that they are grown in pots with good-size drainage holes and a potting medium that absorbs moisture well, almost any plants can be bottom-watered. Keep in mind, though, that bottom watering takes longer than top watering, so if time is an issue, choose top watering.
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.

Grab a handful of your garden soil. If you can form it into a ball, the soil is too wet for planting. (Chances are the seeds will rot.) If it crumbles through your fingers, it's ready for planting.
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.
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start. What does root rot look like?
Cyperus. If your houseplants repeatedly succumb to root rot, get yourself a cyperus. Cyperus plants have tall grass-like shoots topped with slender bracts that droop downward in an umbrella shape. Cyperus are natives of tropical swamps, so it's virtually impossible to overwater them.
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.
However, Epsom salt can still help a tomato plant where the soil is too alkaline or one that has been overwatered. In this way, it helps boost absorption as well as improving photosynthesis in the existing foliage.
