Types of Indoor Plants and Ways to Keep Them Thriving Pest-Free
Indoor gardening is a way to bring a touch of nature into our homes, creating a serene and lively environment. However, keeping these plants flourishing can sometimes feel like a bit of a challenge.
Regardless of your experience this guide is here to help. It will walk you through the unique care requirements of each plant. There are sections on optimizing light and water requirements and how to use our Lost Coast Natural Plant Therapy directed to keep your plants thriving and pest-free.
Understanding the Specific Needs of Indoor Plants
Each indoor plant has unique requirements when it comes to light, water, and overall care.
Succulents
Aloe Vera
Succulents, like jade plants and aloe vera, are the low-maintenance stars of the plant world. These resilient plants are built to withstand drought, thanks to their ability to store water in their thick leaves. Succulents don’t need frequent watering—in fact, they prefer it when you let their soil dry out completely between waterings. Just be sure to use a well-draining soil mix to keep their roots from sitting in moisture, which can lead to root rot.
Tropical Plants
MONSTERA
Tropical plants, like the philodendron and monstera, originate from humid and warm environments. These plants thrive in moist conditions and require regular watering to maintain their lush foliage. The key to caring for tropical plants is to keep the soil consistently moist but not waterlogged. Also, regularly cleaning their large green leaves from dust helps them maximize their ability to absorb light.
Flowering Plants
BROMELIAD
Flowering plants like peace lilies and African violets need a bit more care to encourage their beautiful blooms. These plants often require regular fertilization to meet their nutritional needs. Peace lilies thrive in indirect light and should be watered when the soil feels dry to the touch overwatering can lead to yellowing leaves. African violets, on the other hand, prefer bright, indirect light and consistent moisture. Watering them from the bottom helps prevent water from damaging their delicate leaves.
Ferns
Ferns, including Boston ferns and maidenhair ferns, are fans of indirect light and high humidity. These plants are particularly sensitive to dry air and dry soil, so maintaining a humid environment and consistently moist soil is crucial. A pebble tray with water under the pot or a nearby humidifier can help keep the air around them appropriately humid. Ferns prefer a soil mix that retains moisture without becoming soggy, ensuring they stay hydrated without sitting in excess water.

POTHOS |
Common houseplants, such as the spider plant, rubber plant, and pothos, are the most popular ones to grow for their ease of care. The spider plant, known for its arching green leaves with white stripes, is incredibly forgiving and can thrive in various light conditions, making it one of the easiest houseplants for beginners. It prefers to be watered when the top inch of soil is dry. The rubber plant, with its large, dark green leaves, prefers bright, indirect light and moderate watering. Allow the soil to dry out slightly between waterings to prevent root rot. Pothos plants, with their heart-shaped leaves, are also quite resilient and can tolerate low light conditions. They thrive with occasional watering and are almost impossible to kill.
Specific Watering Schedules and Techniques
Creating a tailored watering schedule for your plant collection is a smart way to ensure each plant gets exactly what it needs to thrive. Succulents typically do well with a bi-weekly check as they prefer deep but infrequent watering, with the soil drying out completely between waterings. Ferns, however, require a bit more attention, as they thrive on consistent moisture. Checking the soil every one to two days and watering when the top layer is dry will keep these moisture-loving plants happy.
Tropical plants benefit from a weekly watering schedule. For snake plants, the soak-and-dry method is ideal—water thoroughly until the excess drains out, then allow the soil to dry out completely before the next round. Prayer plants, which prefer consistent moisture, should be watered carefully to avoid soggy soil. Bottom watering, where the plant’s pot is placed in a tray of water allowing the roots to absorb moisture from below, is especially effective for ferns and prayer plants, promoting deep root growth and reducing the risk of fungal issues.
Managing Temperature and Humidity Levels
Different types of indoor plants have specific temperature preferences. Tropical plants, such as the philodendron, monstera, and rubber plant, thrive in warm conditions, typically between 18°C to 24°C. These plants are accustomed to the consistent warmth of their native habitats and can suffer if exposed to temperatures below10°C. Succulents and cacti, which hail from arid regions, prefer a slightly cooler environment at night, ideally around 13°C to 16°C, but they can tolerate daytime temperatures up to 29°C.
Ferns and other moisture-loving plants, like the Boston fern and maidenhair fern, enjoy moderate temperatures between 15°C to 21°C. They thrive in cooler environments and can be sensitive to heat. Flowering plants such as the African violet and peace lilies prefer stable temperatures in the range of 18°C to 24°C to support blooming.
Maintaining Consistent Humidity Levels
Maintaining consistent humidity levels is crucial, especially for tropical and moisture-loving plants.
In the absence of a humidifier an effective method is using pebble trays. By filling a tray with pebbles and adding water until it just covers them, you create a simple system to boost humidity. Place your plant pots on top of the pebbles, and as the water evaporates, it increases the moisture in the air around the plants. This technique is particularly useful for smaller plants and is easy to integrate into your indoor garden setup.
Grouping plants together is another way to maintain higher humidity levels. As plants release moisture through transpiration, grouping them can create a microenvironment with naturally increased humidity, benefiting all the plants in the cluster.
Optimizing Light Conditions for Indoor Plants
Direct Sunlight
Direct sunlight is ideal for sun-loving plants like succulents, aloe vera, and some flowering plants. Plants like the jade plant and zebra plant absolutely thrive in this intense light. which brings out their brightest colors and fuels their vigorous growth.
Be careful not to place them too close to the glass, where the concentrated heat can scorch them.
Flowering plants like African violets also enjoy direct sunlight but can be sensitive to too much heat. Morning sunlight from an east-facing window is usually gentle enough to give these plants the light they need without the risk of burning their leaves. To help your plants grow evenly, rotate them one to two times a week to ensure they receive balanced light from all sides.
Indirect Light
When it comes to indirect light, many house plants are in their element. The snake plant, peace lilies, and the glossy-leaved rubber plant all thrive in bright, indirect light.
Plants like the fiddle leaf fig and philodendron, with their heart-shaped leaves, also thrive in indirect light. They absorb the bright, diffused light, keeping their foliage lush and vibrant. The spider plant, known for its air-purifying qualities, does well in indirect light too. To maximize light exposure, place these plants near east or west-facing windows, where they can enjoy the gentle morning or afternoon sun without the harsh midday glare.
Low Light
Some plants are true champions of low-light conditions, making them perfect for those shadowy corners of your home. Plants like the ZZ plant and Chinese evergreen are well-adapted to thrive with minimal light. These resilient plants are excellent choices for rooms with little natural light, allowing you to green up spaces that might otherwise feel too dim.
The Chinese evergreen, with its striking variegated leaves, and the cast iron plant, known for its toughness, are perfect for brightening up low-light areas. They’re low maintenance, requiring less frequent watering and happily tolerating varying conditions. Even the elegant peace lily, can flourish in low light.
Using Grow Lights
Natural light is wonderful, but what happens when it’s not enough, especially during those long winter months when other plants may struggle? This is where grow lights are useful.
LED Grow Lights
These lights are energy-efficient and provide a full spectrum of light that closely mimics natural sunlight. LED grow lights are particularly useful for plants that need bright light but can’t get enough from natural sources. They also generate less heat, reducing the risk of overheating your plants.
Incandescent Grow Lights
While not as energy efficient as the others, incandescent grow lights provide additional warmth, which can be a lifesaver for tropical plants that thrive in warmer conditions. During the colder months, these lights can help create a cozy environment for your tropical beauties like the rubber plant and fiddle leaf fig.
Selecting the Right Soil and Potting Mixes
Choosing the right soil is key to ensuring your indoor plants flourish. Each plant has its own preferences when it comes to soil composition. Succulents and cacti thrive in well-draining soil mixes that prevent root rot, while moisture-loving plants like ferns require soil that retains moisture but still allows for good airflow. Tropical plants do best in a rich, organic mix that holds onto moisture without becoming compacted, giving their roots room to breathe.
Remember, well-aerated soil with good drainage is essential to prevent root rot and keep your plants thriving. Using pots with drainage holes and checking the moisture level regularly will help you adjust your watering routine to keep your valued house plants healthy and happy.
Fertilization Schedules and Techniques
Creating a fertilization schedule tailored to your indoor plants’ needs is essential for their health and growth.
Succulents and cacti, for example, have low nutrient requirements and should be fertilized sparingly. A diluted, balanced fertilizer applied about once every two months is usually sufficient. Overdoing it can cause these plants to grow leggy and lose their compact shape.
Ferns and tropical plants thrive with regular feeding. During the growing season, which is typically spring and summer, a balanced, water-soluble fertilizer every two to four weeks can support their lush, vigorous growth. As the weather cools and growth slows down in winter, it’s best to reduce fertilization.
Always remember to water your plants before fertilizing. This ensures that the nutrients are evenly distributed and absorbed by the roots without overwhelming them.
Identifying and Managing Common Indoor Plant Pests
Early detection is key to managing these pests effectively. Regularly inspecting your plants for pests and diseases can help you catch infestations early.
Spider Mites are tiny, often less than 1mm in size, and can be red, green, or yellow. They are notorious for creating fine webs under leaves or at the junction of the stem and leaf. If you notice these webs and tiny moving dots, you are likely to have spider mite infestation. These pests suck the sap from the leaves, causing tiny yellow or white speckles known as stippling. Left unchecked, spider mites can cause leaves to yellow, dry out, and fall off.
Aphids are small, soft-bodied insects that can be green, black, brown, or pink. They tend to cluster on the undersides of leaves and new growth. Aphids feed on plant sap, which can cause leaves to curl, yellow, and deform. They also excrete a sticky substance called honeydew, which can lead to sooty mold growth on the plant.
Thrips are slender, yellow to black insects that are typically 1-2mm long. They feed by scraping the surface of the leaves and sucking out the contents, leaving behind silvery, streaked patches. Thrips can cause significant damage to flowers and leaves, leading to distorted growth and discoloration.
Fungus Gnats are small, dark flies about 2-4mm long. They are often seen flying around the soil of potted plants. While adult fungus gnats are mostly a nuisance, their larvae feed on organic matter and roots in the soil, which can lead to poor plant growth and even root rot.

The Dangers of Chemical Pesticides and Fungicides.
Chemical pesticides are designed to kill pests, but some may also harm humans and pets if not used properly. Many pesticides contain toxic substances that can cause respiratory issues, skin irritation, and even long-term health problems such as neurological damage and cancer. When used indoors, these chemicals can linger in the air, settle on surfaces, and contaminate food and water sources. The risk is especially high for children and pets, who are more likely to encounter treated surfaces and are more vulnerable to the effects of toxins. For those looking to find the perfect balance in caring for indoor plants, avoiding chemical pesticides is a crucial step.
Moreover, chemical pesticides can have detrimental effects on the environment. They can contaminate soil and water, harm beneficial organisms and disrupt ecosystems. Runoff from treated plants can carry these chemicals into natural water bodies, affecting aquatic life and potentially entering the drinking water supply. The overuse of pesticides also leads to the development of resistant pest populations, making it harder to control infestations over time. By choosing natural alternatives and using them as directed, not only can plants live in a healthier environment, but it's also easier to grow them without the risk of contributing to environmental harm.
