Houseplant Care 101: Light, Watering, & Soil Basics for Beginners

Taking care of houseplants so they are happy, healthy, and thriving comes down to finding the right balance between light, water, and soil. When these three elements work together, you create an ideal environment for your indoor plants to thrive. In this guide, we’ll break down the basics in order to set you up for success with your houseplants!

1. Light: Finding the Right Amount

Think of light as food for plants! Light is the energy source for your plants, yet not all houseplants need the same amount. Understanding your plant’s light needs is key to keeping it healthy.

• Bright, direct light – Best for succulents, cacti, and other sun-loving plants. Plants that need bright, direct light do best outdoors. If you keep them indoors, place them near your sunniest window, which are likely south- or west-facing.

• Bright, indirect light – Ideal for most tropical houseplants like pothos, monstera, and peace lilies. If your plant had eyes and could look out the window with a good view of the sky (without looking directly into the sun), then your plant is receiving bright, indirect light. Filter sunlight through curtains or place plants a few feet away from a bright window.

• Low light – Suitable for snake plants, ZZ plants, and ferns. These plants can survive in dimmer rooms but still need some natural or artificial light.

How to Tell if Your Plant Needs More or Less Light

• Too much light: Leaves may scorch, turn brown, or become faded.

• Too little light: Leaves may droop, stretch toward the light, or grow smaller and weaker.

Adjust your plant’s placement as needed, rotating it every few weeks to encourage even growth.

2. Watering: When and How Often?

Think of water as hydration for plants! Overwatering and underwatering are the most common causes of houseplant issues. Overwatering is watering a plant too frequently and not allowing the soil to dry out. The consequences of overwatering include root rot, fungus gnats, mushy leaves, vines or stems. Underwatering is allowing your plant to go too long between watering. It is important to know what type of plant you have and what its basic watering preferences are. The key is watering based on your plant’s needs.

General Watering Guidelines

Saturate the soil completely until water is dripping through the pot’s drainage holes. Avoid just giving your plant a small amount of water at the surface. Remember that the whole root system, from top to bottom, needs water.

• Succulents & cacti – Allow the soil to dry out completely between waterings, approximately every 2–3 weeks. When in doubt, dry them out!

• Tropical plants – Water when the top inch or two of the soil feels dry, approximately once a week to every 10 days.

• Low-light plants – Water when the soil is completely dry, approximately every 2 weeks to a month.

Signs Your Plant Needs Water

• Leaves start to droop or curl.

• Soil feels dry when you stick your finger an inch deep.

• Leaves become wrinkled (common in succulents).

Signs of Overwatering

• Yellowing leaves or soft, mushy stems.

• Mold or fungus growing on the soil.

• A musty smell, indicating root rot.

Don’t just water blindly without checking the soil. Always determine if the soil is dry before watering. Make sure to use pots with drainage holes to prevent water from sitting and collecting at the bottom.

3. Choosing the Right Soil

The right soil ensures your plant gets the nutrients and moisture it needs.

• Succulents & cacti: Use a well-draining cactus mix with sand or perlite.

• Tropical houseplants: A potting mix amended with perlite and orchid bark makes a nice, chunky mix, which helps retain moisture while allowing airflow and drainage.

• Orchids: These plants need bark-based or soilless mixes to allow air circulation around their roots.

How to Improve Soil Drainage

• Mix in perlite or sand for better aeration.

• Use a pot with drainage holes to prevent root rot.

• Avoid compacting the soil too much, as it can block airflow to the roots.

Final Tip: Finding the Right Balance

The key to successful houseplant care is adjusting light, water, and soil based on your plant’s specific needs. If a plant is struggling, check these three factors and make small changes—move it closer to or farther from light, adjust your watering habits, or refresh the soil.

With a little observation and care, plus trial and error, you’ll create the perfect balance for thriving, happy houseplants!
