To dry out soil quickly, you can apply hydrated lime to the soil, add compost and then turn the soil thoroughly to aerate it. Adding hydrated lime and compost will help absorb the water in your soil, and turning it all will help distribute the water in the waterlogged soil throughout your garden.
Add Organic Material
Aside from adding fertility, organic material is also great for breaking up heavy dense soils. By mixing and bonding with soil particles it allows for more air space and drainage. As a side note adding organic material can also help dry soils hold moisture.
The main ways to make soil dry faster are to increase light, heat, and ventilation for your plant, ensure the soil and pot are draining well, and choose an appropriately sized pot for your plant. Consider moving to a pot made of a porous material such as terracotta, and make sure to drain the pot well after watering.
The duration of the rain is the first aspect that impacts how quickly the ground will dry. If the rain was brief, such as 15 minutes, the ground may dry up in 6 hours and you may be able to work on it afterward. However, if there is continuous rain for 4 days, the ground may take longer than 4 days to dry up.
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.
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.
Make sure soil in a new pot is damp already, and water again after transplanting. If you're moving to a new spot in the yard, fill the new hole 3/4 full with water before setting the plant in. Let the water soak in around the plant a bit, pack the soil in, and water again.
Often, soil is dried in an oven in the laboratory. This is usually at 105°C for measurement of the total water content (Topp et al., 2008), but may also be at lower temperatures to remove part of the water.
Make a quick check of soil moisture conditions by taking a handful of soil from planting depth (or tillage depth if planning on doing tillage) and press it in your hands to make a mud ball. If wet soil sticks to your hand, it's probably too wet.
Groundwater depletion can also cause wells to run dry when the top surface of the groundwater – known as the water table – drops so far that the well isn't deep enough to reach it, leaving the well literally high and dry.
Poor Drainage
No matter what kind of indoor plant you grow, drainage holes are essential. A container or pot with inadequate drainage or no holes is bad for the health of the plant. Wet soil is most frequently caused by pots without any holes in them. If you are cultivating aquatic plants at home, moist soil is best.
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).
To fix waterlogged soil, you are going to want to remove the soggy soil or dry it up. Then, be sure that your pot (for indoor plants or outdoor potted plants) or planting area has plenty of drainage to prevent overwatering from happening again.
Give the soil a squeeze to check for moistness. If you squeeze and the soil sticks together then it is moist. But if the soil crumbles or it remains in a loose pile as you squeeze then the ground needs more water. Now drop the soil and brush the soil off your hands.
Soil that is too wet or does not drain properly can suffer from erosion. That which is too dry can become hard and compacted. Additionally, different types of soil respond to moisture differently. Sandy soil will drain water quickly but clay soil will prevent water drainage and become soggy.
As a general rule, 1-3 inches of dried soil is the standard indicator when most potted plants need watering. But drought-tolerant plants only need watering after the entire soil dries out. Additionally, established trees and shrubs require watering once the top 6 to 9 inches of soil is dry.
Water Only When Needed
Too much water can be just as damaging to plants as too little water. Before watering, check your garden's soil moisture with your finger. Push it into the ground around your plants. You want the top 2 or 3 inches of the soil to be dry, and the soil below that to be moist.
You can get waterlogged or overwatered soil to dry out by either repotting the plant or creating an environment that encourages the plant to lose water through evaporation. You could also try relocating the plant to an area that receives more sunlight or has better ventilation overall.
Place approximately one to two inches of soil in the bottom of the pot. Remove the rooted cutting from the water and give it a good rinse with fresh water. Place the cutting in the pot and cover the roots with soil. Leave about an inch of space at the top of the pot.
When you overwater your plant, there are several ways to rescue it. Overwatering doesn't always have to mean that your plant dies. You can let the soil dry, repot your plant in soil or leca, or propagate your plant to not have to give up on your plant and let it die.
Underwatering your plants will result in limp and wilting leaves. Your plants must have enough water to pass through the cells for turgor. If there isn't enough water, the plant will not only wilt but also close its stoma to prevent evaporation.
