If the soil surface is dry, water may puddle or run off and not be absorbed. The solution is to start slowly and gradually build up to a thorough soak. Once the top few inches are moist, the water will be absorbed more easily. Use a watering wand, drip irrigation or soaker hoses to direct water right to the root zone.
Plants get their water from the roots, not the leaves so it is better not to put water on the leaves. If you leave water on the leaves it just evaporates or drops into the soil.
Over-watering can kill a plant more quickly than under-watering. Plants die when too much water in the soil causes the roots to suffocate and begin to rot. Often, the roots have already begun to succumb for rot before symptoms become obvious, and it's too late to treat.
Bottom watering is the recommended method. Top watering tends to cause shallow rooting of the plants and often isn't sufficient.
No, not a good long term solution. Plants need to be thoroughly watered, not spritzed. Without thorough watering then the roots dry out and die off.

On the other hand, there are many indoor plants like succulents and cacti that are native to arid regions and do not require high humidity levels. Spraying these types of plants can actually harm them by creating an environment that encourages mold growth and root rot.
Now, let's tackle the big question: can you overwater your plants by bottom watering? The short answer is yes, but it's less likely than with traditional top watering. Here's why: Soil Saturation: When you leave your plants soaking for too long, the soil can become oversaturated.
Even though we commonly say, "water the plants," it's important to water the base of a plant (i.e., the soil) instead of the plant itself. Water should be poured onto the soil, not the leaves or flowers. This ensures that water ends up where it's needed—at the roots.
If you have a plant with shallow roots, top watering will be the best way to water the roots. Plants like epiphytes, succulents, Snake plants, Calathea, Aloe, more mature Maranta, Sedums, Kalanchoe, Begonias, African violets, and Pothos have shallow roots.
Feel the Soil: The simplest way to gauge your plant's watering needs is by feeling the soil. Turns out that old trick of sticking your finger into the soil up to the knuckle has merit! If it's soggy or has standing water, you're overwatering. If it's dry an inch below the surface, it's time to water.
Our hypothesis was confirmed; the more water the fast plants received the more the plants grew. The correlation between the water intake and plant stem height is apparent when Figure 2 is observed; the plants that received 50 mL of water had much greater growth compared to the plants that just received 5 mL of water.
Leaves Turning Bright Yellow or Mushy Stems
This is usually a sign of overwatering, either caused by watering your plant before it's ready or if your plant is in too low of light. When plants sit in waterlogged soil, their roots can't get enough oxygen, leading to root damage which manifests as yellow leaves.
Don't Water at Mid-Day in the Sun. "Don't Water Your Plants in the Middle of the Day!" How many times have you heard that? "Only water your plants in the early mornings or late evenings." THE CHALLENGE: That's easy to say, but not always easy to do.
Some plants, especially edible crops, come with specific irrigation instructions such as "provide one inch of water per week." One inch of water is 0.68 gallons per square foot.
Provide Slow, Deep Watering
If you are unsure how long to water new plants, aim for 30-60 seconds for small plants – longer for larger plants while moving the hose to a few locations around the plant. Avoid watering when the soil feels moist. The earth must be allowed to dry out between watering.
You should avoid watering the actual leaves or foliage of your plants because water droplets that stay on the leaves can scorch them if left in the blazing sun. Besides, just spraying water on top of your plants is not enough. You have to soak your plants directly at the root system.
Run your sink into a watering can, cup, or bucket, and let it sit for a good 24 hours. This will allow chemicals like chlorine and fluoride the time to evaporate from the water. We like to have a full watering can ready to go with still water so that if our soil seems dry, we can water our plant without waiting a day.
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. For smaller houseplants, you can also pick up the whole container. If it feels light for its size, add water.
Drawbacks of Bottom Watering
Bottom watering isn't very effective if the dirt is too compact, but top watering isn't as effective when the soil has large channels for the water to flow right out. Watering from the bottom doesn't flush out excess salt and minerals like top watering does.
Put the pot (with a drainage hole, of course) into a sink or basin, then fill the basin with lukewarm water until the water almost reaches the top of the pot. Let your varieties soak for about 10 minutes to an hour. You might see a few air bubbles, which are normal.
“In nature, plants will naturally gather humidity from the air, creating dew drops which will freshen the plant leaves and remove dust,” she says. “This ultimately creates a better exchange of oxygen and moisture. Misting one to two times per week can refresh your plants and keep them happy and thriving.”
Avoid creating a routine of watering at the same time every day or every week. Instead, get in the habit of paying attention to the soil and the weather so you can water when the plants really need it. Containers need frequent watering.
Beware of overwatering
Excessive watering is one of the leading causes of issues in the home landscape. Yes, this issue can be a problem even during prolonged dry spells. A condition known as root rot develops, and marigolds, verbenas, hollies, boxwoods, azaleas and rhododendrons are some of the most sensitive.
