Overwatering is the leading cause of houseplant death. It's preferable to be underwater than above water. If your leaves are turning yellow, you may be overwatering. Remove any water from the pot until the foliage returns green, then water again only if the soil becomes dry. Submerging plants will kill them too.
Houseplants need oxygen to live so don't keep them in a completely air-tight container. However, most plants don't need to be exposed to direct sunlight to thrive, so keep this factor in mind when choosing where to place them within the home. Some types of plants do not do well when exposed to high levels of ultraviolet (UV) light from the sun. These include ivy, wisteria, and morning glory. Keep these plants outside during hot summer days.
If you want to give some plants a boost, plant them in a sunny window. But make sure that other plants won't suffer because of their limited exposure to natural light. In addition, some types of plants are sensitive to cold temperatures and should not be placed inside on cold winter days.
Avoid placing plants in glass or ceramic containers as their thick walls block out moisture and nutrients. This can cause the plants' roots to rot away over time. Instead, use plastic or terracotta pots for indoor plants.
If the yellow/brown stains extend from the inner section of the leaf outward, this is another indicator of overwatering. On the contrary, if the plant is under-watered, all of the leaves, not just the bottom ones, will grow softer or droopy.
In either case, your plant needs water, but not too much. Let it dry out completely between doses of water.
If you forget to give your plant a drink, don't worry about it. Most plants can go for several days without water. The only thing that will happen is that its leaves will start to curl up at the edges due to dehydration. When you do give it a drink, wait until night time so that it doesn't evaporate any water.
Keep in mind that plants need water, but they also need sunlight. If you cut off the light, then yes, it would be considered overwatering. However, if you limit the amount of sunlight reaching the plant's surface, then it has no way of getting the energy it needs to grow.
There are two ways to keep track of how much water your plant is getting: use a soil probe or check the label on the plant's pot. If you choose the first method, there are several types of probes on the market. They're easy to use and only cost a few dollars. You can pick one up at any home improvement store.
Overwatering causes plants to drown due to a lack of oxygen or to suffer from root rot and fungus due to an inability to dry out correctly. However, in our efforts to prevent overwatering, we sometimes wind up overcompensating and not providing enough water to our plants. Underwatering is also harmful to the health of your plants. They will not be able to use as much energy being submerged in water, so they will need more air-drying time before they are able to rebalance their systems and recover.
Both forms of watering harmful insects that live in or on your plants. Washing your plants with plain water can remove their protection from pests that want to eat them. And although misting plants during dry periods helps them regulate moisture content inside their leaves, it also prevents them from having time to dry out between showers.
In conclusion, overwatering and underwatering are both harmful practices that should be avoided when caring for your plant collection. Follow these tips if you would like to provide your plants with the best chance at survival: start with well-drained soil, add some organic matter such as compost or rotted manure, and keep an eye out for signs of illness or damage that may require attention from a local gardener or plant specialist.
Overwatering, in a nutshell, drowns your plant. Healthy soil permits oxygen to reside in the gap between soil particles. There aren't enough air pockets if there's too much water if the soil is continually damp. As a result, there is a restricted amount of oxygen, and plants are unable to breathe. The roots suffer from anoxia (lack of oxygen), and eventually die. Plants need oxygen to live; they can't manufacture their own. So, if you over-water, your plant has no way to survive.
If you notice that your plant is getting too wet, lift it up by its roots and move it away from the source of the water. Check with a friend or family member if you're not sure how to do this task safely. You could damage the plant in doing so.
Once you've removed it from excessive moisture, try to keep the soil around its roots dry. Use a hose or drip irrigation system to supply adequate water, but not oversaturated soil. Too much water causes the same problem as overwatering.
If you are unsure whether your plant needs water, feel its leaves. If they are dry to the touch, then it doesn't need any water right now. If they appear green, then it's time to give it some H2O.
Water when seeds start to germinate, and again before you plan to put them in the ground.
The following are symptoms of an overwatered plant:
