How to Take Care of Indoor Plants

Indoor plants bring a cozy and comfortable feeling to a room. They are not only beautiful decorative elements but also serve the purpose of purifying the air, improving your health, and boosting your focus. By creating a suitable environment and providing adequate water and nutrients, you can ensure that your indoor plants thrive.

Keep the soil moist but not soggy. Soil that is too dry or too wet can harm the roots and affect the plant's growth. In some cases, overwatering or underwatering can be fatal to the plant. Plants with thick, lush leaves require more water than those with tougher, wax-covered leaves. There is no universal watering rule that applies to all indoor plants. Instead, you need to identify the type of plant you're growing and follow specific watering guidelines.

• If crust starts forming on the soil surface or there's water pooling at the bottom of the pot, you've overwatered.
• Water the plant when you notice the soil lightening in color or cracking.
• Succulent plants require the soil to dry out completely between waterings.
• If you see water collecting inside or at the bottom of the pot, pour out the excess to avoid root rot. Standing water can kill the plant.

Insert your finger into the soil to check its moisture level. By inserting your finger up to the first knuckle, you'll be able to tell whether your plant needs watering. If the soil is still damp, there’s no need to water. If it feels dry, your plant is likely in need of water.

• Remember, each plant has different water requirements. The advice here works for most plants but not all.
• Signs of overwatering include: yellowing leaves, lack of new shoots, leaf drop, and soft, rotten spots on the plant.
• Signs of underwatering include: slow-growing leaves, brown edges, and dry tips, with leaves turning yellow and curling at the base.

Use room temperature water. A water temperature of 20°C is ideal for watering plants. You can use a thermometer to check the water's temperature or simply leave the water out to reach room temperature.

• If the water is too hot, it could damage the plant’s roots and cause shock, which might kill the plant.
• Cold water can put the plant into dormancy and disrupt its current and future growth.

Use a handheld moisture meter to check soil moisture. Using a meter is the most accurate way to determine a plant’s watering needs. The device probes the soil below the surface and shows the moisture content.

• You can purchase a moisture meter online, at garden stores, or some general retail outlets.

Choose a pot with good drainage. The pot's drainage ability is crucial, as both overwatering and underwatering can harm or kill the plant. Ensure the pot has drainage holes at the bottom.

• Pots made from materials like plastic, metal, or glass will retain less water compared to clay or ceramic pots, so keep this in mind when choosing a pot.
• Make sure your pot has drainage holes. Decorative pots without drainage can trap water and kill the plant.

Choose a location in your home that gets plenty of sunlight. Plants need light for photosynthesis. The quality, duration, and intensity of light all influence plant growth.

• Avoid placing your plant directly in the sun. Instead, provide indirect light by positioning the pot in a well-lit room. Fluorescent lights can substitute for sunlight for some plants.
• Leafy plants require 14-16 hours of light each day.

Don't move your plant too often. Plants take time to adapt to their surroundings, so it's best not to move them around too much. Avoid placing your plant in areas with significant temperature fluctuations.

• Moving a plant suddenly from a dark space to a sunny spot can harm it. If you must move it, do so gradually, increasing the time in the new location each day until the plant is fully acclimated.

Increase humidity in your room. Dry air may benefit some plants like cacti, but most plants, especially tropical ones, require higher humidity. You can use a misting humidifier in the room, but be sure to place it close enough to hydrate the plant without wetting its leaves and flowers.

• A more affordable option is a gravel tray. Fill the tray with water, ensuring it covers the surface of the gravel. As the water evaporates, it will humidify the room.
• You can also use a spray bottle with distilled water to mist the plants and increase humidity.
• Wilting leaves, brown edges, and stunted flower buds are signs that the plant is lacking moisture.
• Planting multiple plants together can also help raise the humidity level.

Add balanced 10-10-10 fertilizer to your plant pot. Most indoor plants thrive with a 10-10-10 balanced fertilizer. Indoor plants need nutrients from both the soil and the fertilizer to survive. Without repotting or adding nutrients, the plant will eventually die. The first number represents nitrogen, the second is phosphorus, and the last is potassium.

• If you're growing flowering plants, you can use fertilizer with a higher potassium content.
• If you're growing leafy plants, opt for a fertilizer or potting mix with higher nitrogen levels.
• Plants also need trace nutrients, which should be included in the soil or fertilizer to ensure survival.
• Cacti or succulents require special soil mixes for proper drainage. They should be planted in pots with ample drainage holes to prevent excessive moisture buildup, which can kill the plant.

Regularly prune your plants. Some plants require periodic root pruning, so make sure you know how often to trim your plant. Unpruned plants can grow out of control, and their roots may start to protrude from the pot. Regular pruning helps the plant grow healthily and can reduce the need for repotting.

• Trim dead branches, as they often attract pests.
• Cut at a 45° angle just above the leaf node to encourage new growth and a fuller plant.

Do not pour tea or coffee into your indoor plant pot. Coffee or tea can attract flies that harm the plants. The sugar content also creates a conducive environment for insects to thrive.

• While some claim that using coffee as fertilizer is beneficial for plants, in reality, this can kill plants that cannot tolerate high acid levels.

Understand plant classification. There are many online encyclopedias where you can find detailed care instructions for your plant, including information on humidity, light, and watering needs. Since there are so many types of indoor plants, it's crucial to know the ideal environment for your specific plant.

• Most indoor plants are labeled with both common and scientific names. If your plant isn't labeled, ask the seller. The scientific name of a plant consists of two parts: genus and species. For example, Spathiphyllum wallisii is the scientific name for the peace lily. Many plants have common names that are also their scientific names. If you see an 'x', a third name, or a name in quotation marks, this refers to a cultivar, hybrid, or subspecies.
• Some plants have general names like palm or desert cactus. With expert advice and reference books, you can learn to identify many genera (even if you can’t pinpoint the exact species) by observing the plant.
• If you have an indoor plant and aren’t sure of its type, search for images in plant books, encyclopedias, or houseplant guides, and match the pictures to your plant.
• Find the accurate name for the species and variety of your plant to ensure you select the right one. A genus can include millions of species and varieties. Some species and varieties are easier to grow indoors than others or their wild counterparts. Additionally, some plants grow large, while others are vining. This is true for groups like Philodendron (pothos) and Anthurium (flamingo flower).

Note that not all plants sold as houseplants can thrive indoors. Many plants sold as indoor varieties are not actually suited to indoor environments. Often, people unknowingly buy these types of plants and are disappointed when they die after being brought home, which discourages them from ever purchasing indoor plants again.

• Many flowering houseplants are annuals (living for only one year before dying). Persian violets and ornamental peppers will die after flowering and need to be discarded. Wild pineapples die after flowering but produce offshoots, which can be separated from the mother plant and potted separately, or left as is.
• Other plants like mini roses, hydrangeas, and Christmas cacti are woody or perennial shrubs, which actually need to be grown outdoors to survive, like other plants of their kind. Similarly, spring-blooming bulbs like tulips, lilies, and daffodils require outdoor environments.
• Many other plants, including tropical shrubs, bulbs, and perennials, undergo a less appealing phase after their vibrant blooming period, requiring special care to return to their former beauty. Examples include poinsettias (sold during Christmas), anthuriums, and many summer/tropical bulb plants like gladiolus and dahlias.
• Additionally, some plants will no longer look attractive after one or two years, even with proper care, and will need to be replaced. Examples include coleus, mirror grass, velvet flowers, and striped begonias.
• Most plants sold in baskets or pots with multiple species need to be separated. These plants are grouped together based on appearance rather than the individual needs of each plant. The exception is desert plants and those specially grown in terrariums.

Determine whether your plant is a foliage or flowering type. Foliage plants differ from flowering plants and have distinct needs in terms of nutrition, water, and light.

• Most popular houseplants belong to a large group known as angiosperms or flowering plants. However, not all angiosperms produce beautiful flowers or bloom during the season you expect. Additionally, many plants may never reach maturity when grown indoors.
• Flowering and/or fruit-bearing angiosperms include jasmine, lilies, poinsettia, anthurium, and red calla lilies. Most orchid species are also part of this group.
• Foliage angiosperms include the lucky bamboo, marantas, peacock plant, spider plant, ivy, and two common types: palms and ficus.
• Some plants offer both stunning flowers and foliage. A large genus, Begonias (begonias), is a prime example of this group. Other plants include cacti, succulents, and many hybrids bred for colorful leaves and eye-catching spots.
• Gymnosperms are plants that do not have flowers but instead produce seeds encased in cones. Coniferous trees like pines and spruces are examples of this group. The “Christmas tree,” also known as Norfolk Island pine, along with its close relatives, belongs here. The sago palm, although named palm, is a member of the cycad group, related to the “money tree.” These plants take years to produce cones, and they are foliage plants.
• Ferns are not part of angiosperms or gymnosperms. These plants, along with others like mosses, reproduce via spores rather than flowers or cones. These are foliage plants.
• Some plants are incorrectly marketed. For example, some places sell cacti with added flowers or decorate any plant to make it look like it is blooming. The lucky bamboo (called “lucky bamboo” in English) is not a type of grass or bamboo but belongs to the genus Dracaena. Some stores even paint or dye plants and flowers, leading customers to believe the colors are natural. While dyed flowers are not a major issue, paint on the plant can block necessary light for photosynthesis.

Choose easy-to-care-for plants. Some tropical plants require specific environments to thrive, while others like geraniums, sago palms, pothos, and wild garlic are highly resilient and low-maintenance. Many cacti and succulents are also known for their unique appearance and ease of care.

• Other plants that do not require much light include snake plants, dracaena, and spider plants.
• The Aglaonema, often grown in public spaces, is also easy to care for in low light but doesn’t do well in cold and damp conditions. It may gradually shed lower leaves but can thrive in water-based environments.

• Some plants contain toxic chemicals in their leaves that are harmful to pets and small animals, including peace lilies, oleander, and ornamental caladiums. It's important to research plants you plan to have indoors if you have children or pets.
