It can be a joy to grow houseplants, but it can be difficult to keep them looking fresh and healthy all the time. One of the most frequent queries, whether from novice or seasoned gardeners, is “why do indoor plant leaves turn brown?” Fortunately, figuring out why this is happening and taking action to lessen and prevent it are not difficult.
Why do the leaves of house plants deteriorate? Your indoor plants’ leaves becoming brown could be caused by a variety of factors, including inadequate watering, feeding, or transplant shock; environmental factors like lighting, heat, drafts, or humidity; insect or disease problems; or natural factors like acclimation or aging.
It’s crucial to identify precisely where on the plant the issue is occurring in order to comprehend the main factors listed below and why your plant’s leaves are becoming brown. After that, you can attempt to fix the issue.
Why do house plants deteriorate?
Because they are maintained in an unnatural environment, houseplants are unique. They rely on you for all that nature would otherwise provide for them, and they alert you to your errors. When indoor plants have brown leaves, it nearly always indicates that they are either receiving too much or too little of a critical element.
Light
Lack of light is a very typical issue with indoor plants. The leaves of your plant will begin to turn brown if it is not receiving enough light. You can be fairly certain that this is the issue if the plant’s side that faces away from the light source has brown leaves.
Water
Another common cause of dark leaves on indoor plants is inadequate watering. In this instance, the browning and curling typically start at the plant’s base and work their way up.
Humidity
Another frequent issue that most people overlook is a lack of humidity. Particularly tropical plants require more humidity than a typical home is likely to provide. The leaves typically only darken at the tips as a result of this. Consider spraying your plant with water or submerging the container in a dish with water and small stones.
Heat
Another issue is excessive heat, which usually results in leaves that turn brown, curl, and drop off. Try making those modifications first since this issue frequently results from either too much sun or little water. The plant can also be relocated to a location with greater airflow.

We’ve experienced our fair share of brown, decaying leaves as we’ve learned how to properly care for various home plants over the years. We weren’t sure at first whether to take them out or leave them. Here is what we’ve discovered works the best.
Do you need to remove the dead leaves? Yes. Your indoor plants should have brown and withering leaves removed as quickly as possible, but only if they are more than 50% damaged. By removing these leaves, the plant looks better and the healthy foliage that is left can receive more nutrients.
Even though it might appear straightforward, there’s more to it than merely cutting those leaves off. To keep your plant healthy, you must assess how much of the leaf is dying and then carefully remove the damaged areas.
Why are my plant’s leaves fading to brown?
Typically, underwatering, sunburn, or overwatering are the causes of browning leaves.
The soil possibly grew too dry for an extended period of time between waterings if the leaf tips are turning brown and hard. The plant may lose leaves as a result of this. This does not necessarily imply that you are regularly underwatering because the browning may have only occurred once. Although the brown leaf tips won’t turn green again, you can trim the brown margins to restore the plant’s healthy appearance. Go here to learn more.
It may also be a symptom of overwatering if you see brown patches all over the leaves. You’ll typically notice some yellowing of the leaves as well when the plant is overwatered. Go here to learn more.
If you see brown stains in the middle of the leaves, it may be because the leaves are receiving too much direct sunshine. Some plants are readily burned by direct sunlight and are sensitive to it. If this is the case, try shifting your plant to a spot where it won’t be exposed to the sun’s glare.
– If you move your plants from indoors to outdoors in the summer without acclimating them to direct sunshine, this is usually what happens.
How frequently ought indoor plants to be watered?
Although watering houseplants may seem like a straightforward operation, many people either overwater them or neglect them until they get parched. Generally speaking, the potting soil for indoor plants should be kept moist but not wet. They normally need watering once or twice a week in the spring and summer, but less in the autumn and winter. However, this isn’t always the case, depending on the kind of houseplant.
- Only give orchids a small bit of water once a week to water them.
- Succulents and cacti need relatively little water. When the potting mix has dried out, only water.
- Water citrus plants more frequently and consistently than you would other houseplants.
The Westland Watering Indicator makes it easier to know when to water. This watering stick is very simple to use and may be used all year round. Just insert the stick into the pot of compost. The indicator will then turn red to let you know when the plant needs extra water. When no additional water is required, the indicator will turn blue. Within two hours of watering the plant, the indicator’s color should shift from red to blue.
Another crucial factor is the type of water used on indoor plants. This is due to the fact that many plants are sensitive to the salts and chemicals found in tap water. So it is advisable to use rainwater to water your plants.
Feeding
To promote lush, robust growth, indoor plants must be fed while they are developing. Only while a houseplant is actively developing, not when it is dormant, should it be fed.
During the growing season (spring and summer), the majority of indoor plants need typically be fed every other watering, or around every 10 to 14 days. In the fall and winter, feed indoor plants after every fourth watering because they will need fewer nutrients.
Using a liquid concentrate feed is a good approach to feed houseplants. These are a fantastic way to feed and water your plant simultaneously. They work best, though, when the mixture isn’t created too powerful or too weak. Given that it is filled with the necessary nutrients, Westland Houseplant Feed is a fantastic plant food for indoor plants. Additionally, it contains a simple measure doser that requires only a squeeze of the bottle to fill the dosing chamber. Any extra plant food will be removed by the doser, leaving you with a 5ml dose to mix with 1 liter of water. This indicates that the combination you use to feed your plants is the proper strength.
The list of specialized feeds for various types of indoor plants that include the precise ratio of nutrients required for their growth is provided below.
- Feed for succulents and cacti offers nutrients that improve flowering.
- Citrus feed: provides nutrients that promote fruit development and set.
Do dark leaves indicate an excess of water?
One of the major problems I notice with modern landscaping is overwatering the plants. These are some of the few indicators of overwatering plants. It is tempting to give plants more water when they don’t appear healthy, but this is frequently a mistake. An overwatering error is difficult to identify because it frequently seems like a water shortage.
The following six indicators can help you assess if you are overwatering your plants or not:
Your plant is wilting but it looks like it has plenty of water
For survival and growth, plant roots absorb both water and oxygen. Simply put, if you give your plants too much water, they will drown. In your garden, there is gap between the soil granules. It is filled with oxygen. Continuously soggy soil won’t have enough air spaces, which prevents plants from breathing by using their roots to absorb oxygen. When this happens, even while the soil is moist, your plants will wilt, giving the appearance that they are not getting enough water. Here is a fantastic video explaining the drawbacks of giving your plants too much water from our colleagues at Denver Water.
The tips of the leaves turn brown
The tip of the leaf is one of the first and quickest indications that you have overwatered your plants. Overwatering is evident if the leaf’s tip is turning brown. When your plant receives too much water, the leaves become limp and squishy, while when it receives too little water, the leaves feel dry and crispy to the touch.
Leaves turn brown and wilt
When plants receive either too little or too much water, their leaves wilt and turn brown. The greatest distinction is that too little water causes the leaves to feel crunchy in your palm. The leaves will feel floppy and mushy in your palm if there is too much water present.
EDMA
Water pressure starts to build in the leaf cells when a plant’s roots take up more water than they can utilise. Eventually, the cells will burst, killing them and causing blisters that resemble lesions. Where the blisters formerly were, tan, brown, or white warty growths start to appear after they erupt. On the top surfaces of the leaves, you will also notice indentations developing directly above the growths.
Leaf fall
Both scenarios of too much and too little water result in leaf fall. When buds don’t develop and both new and old leaves fall off before they should, there is definitely too much water in the soil.
How do you fix overwatering?
Examine your soil frequently. Never be hesitant to stick your finger a few inches into the ground to check the moisture level. Reduce your water use if the soil is wet and you meet some of the other requirements. Additionally, several shops offer reasonably priced moisture meters. To find out how much water is in the soil, simply bury them in the root ball. This is a straightforward, low-cost instrument that will eliminate a lot of the guesswork involved in watering your environment.
I sincerely hope that these suggestions will be useful, and I invite you to add a couple of your own to prevent overwatering your plants in the section below. Please consider subscribing to the blog and following me on Twitter at @H2OTrends if you liked this post.
What symptoms indicate overwatering?
To keep your plants healthy, watch out for these five signs of overwatering:
1. If a plant is overwatered, it will probably produce limp, droopy leaves that are yellow or brown rather than dry, crispy leaves (which are a sign of too little water). Wilting leaves and soggy ground typically indicate that root rot has taken hold and the roots are unable to absorb water.
2. You’ve probably overwatered if your plant is losing both old and new leaves at the same time. Bear in mind that the leaves that are falling off can be green, brown, or yellow.
3. You’ve overwatered the plant if the base of the stem starts to feel mushy or unsteady. Even a foul odor may start to come from the earth.
4. An overwatering-related bacterial infection appears as brown spots or margins around the leaves that are surrounded by a yellow halo.
5. If you have repeatedly overwatered your plants, fungus or mold may develop directly on top of the soil, similar to symptom number three. Fungus gnats are another typical indicator of overwatering.
Do I need to remove the Brown palm leaves?
Both too much and not enough water will harm palm trees and cause leaf browning and yellowing.
The majority of palms prefer to have 50% of their soil dry before being irrigated. Always be sure the soil needs water before applying it. Wash the saucer thoroughly, then drain any extra water. Overwatering can cause yellowing and eventually root damage.
When the leaf tips dry out and turn brown, this is a typical issue known as “tipping.” The most frequent culprit is tap water, which has salts, chlorine, fluoride, and other potentially dangerous substances in excess. Use distilled water or rainfall to avoid this.
If you start to see salt buildup as a white crust-like coating on the soil’s surface, you can flush the soil a few times a year. To accomplish this, remove the top layer of dirt and water your palm slowly but liberally with a volume of water that is roughly four times that of your pot. Before repositioning your Palm, allow the water in the pot to completely drain and remove any extra water from the saucer.
Nutrients in the potting soil are replenished by fertilizer, but too much fertilizer can cause leaf tips to become brown and compromise plant health. Only fertilize palm trees in the spring and summer when they are actively growing. Palms that are dormant don’t require more fertilizer. Use palm tree fertilizer at the rate suggested on the box. Keep in mind that more fertilizer is not always better. Never fertilize dry soil because doing so can cause the roots to burn.
Warm temperatures are necessary for palms to thrive. Despite being often kept warm, indoor plants are nonetheless susceptible to cold harm. Plants should be kept away from windows and doors that draft because the cold air can brown the tips of the leaves. In the winter, keep plants away from windows because leaves contacting the glass might freeze and become brown. Avoid placing items directly in an air conditioning vent during the heat.
Throughout the growing season, palms grow new leaves. A palm tree leaf gets dark as it nears the end of its natural life, starting at the tip and continuing until the leaf is entirely brown and falls off. The brown tips are normal and not cause for alarm if only one or two leaves are browning and new foliage is still coming in.
The right way to remove any brown tips from your plant is as follows:
- Amass your resources. Paper towel, some rubbing alcohol, and a pair of well-kept scissors or pruning shears are all required. (The alcohol wipes included in first-aid kits are excellent!)
- Before starting and after each cut, wipe the sharp scissors or pruning shears’ blades with rubbing alcohol. The blades should be wetted with water before cutting if you are simply removing brown, crispy leaves that have become that way due to aging, a lack of moisture, or sunburn patches. This will help to avoid damaging vital tissue.
- At the base, close to the stem, or at the soil, remove any leaves that are completely brown or yellow. Make sure not to tug on the leaves as this could harm the plant’s vital components. Remove only the afflicted section of the leaf if only a portion of it is brown or yellow.
Important: When pruning, take care not to take more than 30% of the entire plant. To avoid removing an excessive amount of leaves at once, you might need to prune in phases.
