Boston Ferns (Nephrolepis exaltata) are popular houseplants known for their elegant, feathery fronds. Growing them indoors is relatively straightforward if you understand their basic requirements.

Choosing the Right Spot

  • Light: Boston Ferns prefer indirect light. A north-facing or east-facing window is ideal. If placing near a south or west-facing window, ensure the plant is shielded from direct sunlight, as this can scorch the leaves.
  • Temperature: These ferns thrive in temperatures between 65°F and 75°F (18°C - 24°C). Avoid placing them near radiators, air conditioners, or drafty windows to prevent sudden temperature fluctuations.


Boston Ferns love moisture. Keep the soil consistently damp but not soggy. Overwatering can lead to root rot.

Check the soil regularly. If the top inch feels dry, it's time to water. Use room-temperature water to avoid shocking the plant.

If your home has dry air, especially during winter, consider placing a tray with water and pebbles beneath the plant pot. As the water evaporates, it'll increase the humidity around the fern.

Soil and Potting

Use a high-quality potting mix designed for ferns or indoor plants. Ensure it has good drainage. Boston Ferns prefer pots with drainage holes to avoid water accumulation at the bottom.


During the growing season (spring and summer), feed your fern with a balanced liquid fertilizer every 4-6 weeks. Reduce feeding in the fall and winter when growth slows down.


Trim off any yellow or brown fronds at the base to keep the plant looking fresh and to encourage new growth.


Boston Ferns love high humidity. Regular misting with water can help, especially during dry seasons or if you're using central heating.
Consider using a humidifier if you're growing ferns in particularly dry environments.


Boston Ferns can become root-bound after a couple of years. If you notice slower growth or roots creeping out of the drainage holes, it might be time to repot. Choose a pot 1-2 inches larger in diameter than the current one.

Pest Management

Keep an eye out for pests like spider mites and mealybugs. If you spot any, isolate the plant and treat it using insecticidal soap or neem oil.

General Care

Keep the fronds clean by gently wiping them with a damp cloth or giving the plant a lukewarm shower every once in a while. This not only cleans the fronds but also increases humidity.

Note that Boston Ferns are sensitive to chemicals found in tap water, like chlorine and fluoride. Consider using filtered or distilled water to avoid browning tips and edges.

With the right care and attention, your Boston Fern will thrive indoors, adding a touch of green elegance to your living space.

Snake Plant (Sansevieria trifasciata)

Snake Plant (Sansevieria trifasciata) is a very popular houseplant that not only adds more oxygen but also filters out carbon monoxide, formaldehyde, and benzene.

Snake Plants, or Sansevieria trifasciata, are among the most resilient and popular houseplants. Their sleek, upright leaves make them a favorite for interior decor, and their low-maintenance nature is a plus for both newbies and seasoned plant enthusiasts.

Choosing the Right Spot

Light: Snake Plants are versatile when it comes to light. They can tolerate low light conditions but grow best in indirect sunlight. A spot near an east or north-facing window would be great, but they can also adapt to brighter west or south-facing windows.

Temperature: These plants prefer temperatures between 70°F and 90°F (21°C - 32°C). They can handle cooler temperatures, but try to keep them above 50°F (10°C).


Snake Plants are succulents, meaning they store water in their leaves. As a result, they don't require frequent watering. Wait until the soil is completely dry before watering again. Overwatering is a common mistake; it's better to err on the side of too dry than too wet.

Water sparingly during the winter months when the plant is less active.

Soil and Potting

Opt for a well-draining potting mix, preferably a cactus or succulent mix. Ensure the pot has drainage holes to prevent water accumulation and root rot.


Snake Plants aren't heavy feeders. During the growing season (spring and summer), you can feed them with a general-purpose houseplant fertilizer, diluted to half the recommended strength, every 6-8 weeks.

No need to fertilize in the fall and winter.


Snake Plants grow slowly and can thrive in tight pots. Repot only when the plant is visibly root-bound or every 2-3 years. When you do repot, choose a container only slightly larger than the current one.

General Care

Snake Plants are known to purify indoor air, but they'll do best if you keep their leaves clean. Every so often, wipe the leaves down with a damp cloth to remove dust.

Keep an eye out for pests like mealybugs or spider mites. If any are spotted, use insecticidal soap or neem oil as a treatment.


One of the joys of Snake Plants is their ease of propagation. If you want to create more plants, simply divide the plant when repotting or cut leaf segments and plant them in the soil.

While Snake Plants are tough, it's essential to avoid letting them sit in water. If using a saucer beneath the pot, empty it after watering so the plant doesn't remain in standing water.

With minimal care and a bit of love, your Snake Plant will not only beautify your space but also purify your indoor air.

Peace Lily

Peace Lily has been listed among the top oxygen-producing plants and is also known for purifying the air by removing toxins.

Temperature: Aim for a comfortable room temperature between 65°F and 80°F (18°C - 27°C). Peace Lilies aren't fans of sudden temperature drops, so keep them away from drafty spots.

Watering Routine

Peace Lilies like their soil to be moist but not soggy. When the top inch of soil feels dry, it's time to water.

These plants are known to droop a little when thirsty. If you see this, give them a drink, and they'll perk up in no time!

Use lukewarm or room-temperature water, as cold water can shock the plant.

Soil and Container

A well-draining, all-purpose potting mix works well for Peace Lilies. Ensure your pot has drainage holes to prevent overwatering and root rot.

Feeding Your Plant

During the growing season (spring and summer), feed your Peace Lily once a month with a balanced, liquid houseplant fertilizer at half the recommended strength.

Hold off on fertilizing in the winter months.

Pruning and Maintenance

To keep your plant looking its best, trim any yellow or brown leaves at the base.

Remove spent flowers to encourage new blooms.

Boosting Humidity

Peace Lilies enjoy higher humidity levels. Consider placing the pot on a tray filled with pebbles and water (without the pot touching the water) or occasionally misting the plant.

A room humidifier can also benefit the plant, especially during drier months.


Every couple of years or when the plant becomes root-bound, transfer your Peace Lily to a slightly larger pot. This is usually evident when you see roots emerging from the drainage holes or the soil drying out too quickly.

Watching Out for Pests

Keep an eye out for common houseplant pests like spider mites, aphids, and mealybugs. In case of an infestation, treat the plant with insecticidal soap or neem oil.

Peace Lilies are beautiful to behold, but remember that they are toxic to pets. If ingested, they can cause irritation and symptoms of poisoning in animals. It's best to keep them out of reach if you have curious pets around.

Nurturing a Peace Lily indoors can be a gratifying experience. With just a little attention to its needs, this plant will reward you with a lush display of greenery and occasional white blooms, brightening up any indoor space.

Temperature: These palms prefer temperatures between 65°F and 75°F (18°C - 24°C) during the day and a little cooler at night.

Hydration Habits

Areca Palms like their soil to remain moist but never waterlogged. Water when the top inch of the soil feels dry to the touch.

Use lukewarm water, ensuring it's free from chemicals like fluoride and chlorine, as these can brown the leaf tips. Letting tap water sit out overnight can help to evaporate some of these chemicals.

Soil and Pot Selection

Choose a potting mix that provides good drainage, like a palm or a general-purpose potting mix.

The pot should have ample drainage holes to prevent overwatering and the onset of root rot.

Nutrient Needs

During the growing season (spring and summer), feed your Areca Palm every 2-4 weeks with a balanced liquid fertilizer. Come fall and winter, reduce the feeding frequency.

Pruning and Care

Trim any brown or yellowing fronds at the base using sterilized pruning shears. This not only improves the plant's appearance but also promotes growth.

If the leaf tips turn brown, it could be due to dry air, over-fertilization, or fluoridated water.

Ensuring Humidity

Areca Palms appreciate higher humidity, especially during dry winter months. You can boost humidity by misting the fronds, placing the plant on a tray of wet pebbles, or using a room humidifier.

Repotting Advice

Young Areca Palms may need repotting annually. As they mature, repotting every 2-3 years should suffice. When repotting, select a container just a couple of inches larger in diameter than the current one.

Stay Vigilant for Pests

Watch out for pests like spider mites, aphids, and mealybugs. If you notice any, treat your palm promptly with insecticidal soap or neem oil.

While Areca Palms are relatively easygoing, consistency is key. Regularly checking on your plant and attending to its needs will ensure it remains vibrant and healthy.

Growing an Areca Palm indoors can be incredibly rewarding. With proper care, it will serve as a lush, green focal point in your home for years to come.

Aloe Vera

Besides its medicinal properties, Aloe Vera is recognized for its oxygen production and air-purifying capabilities.

aloe vera

Aloe Vera is not only renowned for its soothing gel but also as a resilient houseplant that brings a touch of the desert indoors. With its spiky, green leaves and easy-care nature, it's a favorite for many indoor gardeners.

Picking the Right Location

Light: Aloe Vera thrives in bright, indirect sunlight. A south or west-facing window shielded by sheer curtains or blinds is perfect. While it appreciates a good amount of light, direct, harsh sunlight can scorch its leaves.

Temperature: Aloe prefers temperatures between 55°F and 80°F (13°C - 27°C). Keep it away from cold drafts, radiators, or direct heat sources.


Aloe Vera is a succulent, which means it stores water in its leaves and doesn’t need frequent watering. Wait until the top couple of inches of soil are dry before watering. When in doubt, it's better to underwater than overwater.

During the dormant period in fall and winter, you'll need to water even less frequently.

The Ideal Soil and Pot

Use a well-draining potting mix, ideally one formulated for cacti and succulents.

Choose a container with drainage holes. This is crucial to prevent water from sitting at the bottom, which can lead to root rot. Terra-cotta pots are especially good for Aloe Vera due to their porous nature.

Feeding Your Plant

Aloe Vera isn't a heavy feeder. Using a balanced, water-soluble fertilizer diluted to half strength, feed the plant once in the spring and again in late summer.

Pruning and Harvesting

Remove (or harvest) any outermost, mature leaves using clean, sharp scissors or a knife. Cut close to the base. This not only encourages new growth but gives you some aloe gel to use!

If any leaves turn brown or mushy, trim them off to keep the plant healthy.

Maintaining Humidity

Aloe Vera is quite adaptable and doesn't require high humidity. However, if your indoor air is exceptionally dry, occasional misting won't hurt.

Repotting Tips

As your Aloe Vera grows and produces "pups" or baby plants, it may become pot-bound. Consider repotting every 2-3 years or when the container is visibly crowded.

When repotting, be gentle with the roots and use the opportunity to separate any pups to grow new plants.

Pests Control

Aloe Vera can occasionally attract pests like aphids or mealybugs. Regularly inspect your plant, and if you spot any unwelcome guests, wipe the leaves with a cloth dipped in soapy water or treat them with insecticidal soap.

While Aloe Vera gel is beneficial for cuts and burns, the plant's sap (yellow liquid) can be irritating to the skin and harmful if ingested. If you have pets or young children, ensure they don't nibble on the plant.

With just a bit of love and care, your Aloe Vera will thrive indoors, providing you both aesthetic pleasure and a natural remedy for skin ailments.

Spider Plant

Spider Plant is known to enhance air quality by adding more oxygen and filtering out harmful gases like carbon monoxide, formaldehyde, and benzene.
