With a few simple tips, you’ll become a pro at selecting planters that help your indoor plants flourish. This guide will walk you through everything you need to know to give your plants the best possible start in their new homes.

But before we dive in, let’s quickly break down what makes a planter “good” for an indoor plant.

What Makes a Planter Ideal for Indoor Plants?

The perfect planter for an indoor plant isn’t just about looks; it needs to provide the right environment for your plant’s roots to thrive. Think of it as a little home that supports its well-being.

Here are the key characteristics of a great indoor plant planter:

Proper Drainage: This is non-negotiable! Without a way for excess water to escape, roots can sit in soggy soil, leading to rot. Look for planters with drainage holes at the bottom.
Appropriate Size: A pot that’s too big can hold too much moisture, while one that’s too small will stunt growth. Generally, a new pot should be only 1-2 inches larger than the current one.
Ventilation: Roots need to breathe! Porous materials allow for better air circulation.
Material Benefits: Different materials offer unique advantages for moisture retention and aeration.
Stability: The planter should be sturdy enough to support the plant as it grows and prevent tipping.

Pros:
Excellent aeration and drainage.
Porous nature helps prevent overwatering by allowing soil to dry out faster.
Heavy, providing good stability for larger plants.
Natural, earthy aesthetic.
Relatively inexpensive.
Cons:
They dry out very quickly, requiring more frequent watering, especially in warm, dry conditions.
Can develop mineral deposits on the outside over time, which can be scrubbed off.
Brittle and can break if dropped.
Can be heavy to move.

2. Ceramic

Ceramic pots are often glazed on the outside, giving them a decorative appeal. Unglazed ceramic is similar to terracotta but less porous.

Pros:
Wide variety of decorative styles, colors, and finishes.
Glazed interiors help retain moisture better than terracotta.
Durable and long-lasting.
Cons:
Often lack drainage holes, and if they do, they might be small. You’ll likely need to drill them or use them as cachepots.
Can be heavier than plastic.
Can be more expensive.
Glazed interior can lead to overwatering issues if drainage is poor or watering is too frequent.

Pros:
Lightweight and easy to handle.
Inexpensive.
Durable and won’t break easily.
Retains moisture well, which can be good for plants that prefer consistently moist soil.
Easy to clean.
Cons:
Less breathable, so roots may not get as much air.
Can lead to overwatering if you’re not careful, as soil dries out slowly.
Can become brittle and fade in direct sunlight over time.
Some find them less aesthetically pleasing than natural materials.

4. Polypropylene

Similar to plastic, but often more durable and UV-resistant. It’s a very common material for “nursery pots” – the basic pots your plants come in from the store.

Pros:
Lightweight and strong.
Cost-effective.
Good at retaining moisture, but often designed with adequate drainage.
Many are made from recycled materials.
Cons:
Can still have breathability issues compared to porous materials.
Aesthetics are often basic.

5. Metal

Metal planters can add a modern or industrial look to your home decor.

Pros:
Durable and stylish.
Can be lightweight or heavy depending on the type of metal.
Cons:
Can heat up significantly in direct sun, potentially damaging roots.
Prone to rust, especially if not treated.
Often lack drainage holes, requiring modification or use as a cachepot.
Can be expensive.

6. Concrete

Concrete planters are sturdy, modern, and can be quite heavy.

Pros:
Extremely durable and long-lasting.
Excellent stability.
Modern aesthetic.
Porous to some extent, allowing for some air exchange.
Cons:
Very heavy, making them difficult to move.
Can be expensive.
Can leach lime into the soil, which can make it more alkaline over time. This might affect plants that prefer acidic soil.
Can be very porous, leading to fast drying times.

7. Woven/Natural Fiber Baskets

Baskets made from seagrass, rattan, jute, or wicker are popular for their natural texture and style.

Pros:
Beautiful, natural aesthetic.
Lightweight.
Good airflow.
Cons:
Usually used as decorative outer pots (cachepots) as they lack drainage and can degrade with constant moisture.
Can be expensive.
May attract pests if not kept clean.

8. Self-Watering Planters

These innovative planters have a reservoir that holds water and a wicking system to deliver moisture to the soil as needed.

Pros:
Takes the guesswork out of watering.
Great for busy people or those who travel.
Helps prevent over- and under-watering.
Many come with a water level indicator.
Cons:
Can be more expensive than traditional planters.
The reservoir needs occasional cleaning to prevent algae or root rot issues.
Not suitable for all plant types (e.g., succulents and cacti that need to dry out completely).
Root systems can sometimes become accustomed to constant moisture, making it harder to transition back to traditional pots.

The Importance of Drainage Holes

This is the single most critical feature of any planter for an indoor plant. Even the most expensive or beautiful pot is useless for plant health if it doesn’t allow water to escape.

Why are drainage holes essential? Excess water trapped in a pot creates a waterlogged environment. Roots need oxygen just as much as they need water. In a waterlogged pot, the soil fills with water, displacing air. This deprives the roots of oxygen, leading to root rot. Root rot is often fatal and very difficult to recover from.
What if my planter doesn’t have holes?
Drill them: If you have a ceramic or plastic pot without drainage, you might be able to add them yourself using a suitable drill bit. Be cautious with delicate materials. For ceramic or glass, a diamond-tipped drill bit and water lubrication are usually required. Always wear safety glasses.
Use as a cachepot: The most common and safest method is to use the decorative pot without drainage holes as a “cachepot.” This means you’ll place your plant in its plastic nursery pot (which has drainage holes!) inside the decorative pot. When you water the plant, let it drain thoroughly in a sink or bathtub. Once it stops dripping, place it back into the decorative pot. Ensure no water sits at the bottom of the cachepot. You can place a layer of pebbles at the bottom of the cachepot to elevate the nursery pot, but avoid letting the nursery pot sit in standing water.

How to Determine the Right Planter Size

Choosing the correct size is vital. Too large a pot can lead to a host of problems, while too small a pot will restrict your plant’s growth.

For Repotting: When you repot a plant, you typically want to move it up to a pot that is 1-2 inches larger in diameter than its current pot. For very large plants, you might go up 2-3 inches.
Signs your plant needs a bigger pot:
Roots are growing out of the drainage holes.
You can see a dense network of roots circling the soil (root-bound).
The plant dries out significantly faster than usual.
The plant doesn’t seem to be growing, or its growth has slowed considerably.
The soil line has dropped significantly away from the pot’s edge.
Signs your pot might be too big:
The soil stays wet for an extended period (more than a week or two, depending on the plant and conditions).
The plant looks disproportionately small for the pot size.
You notice signs of root rot (yellowing leaves, mushy stems).

Repurposed Containers:
Old teacups or mugs: Perfect for small succulents or herbs. Ensure they have drainage holes added or use them as cachepots.
Tin cans: Cleaned out cans can make rustic planters. Drill drainage holes in the bottom. You can paint or decorate them to enhance their look.
Colanders: They already have plenty of drainage holes! Line them with coco liner or sphagnum moss to prevent soil loss.
Colanders: Yes, kitchen colanders! They naturally have many holes for excellent drainage and aeration. You can add a layer of coco liner or sphagnum moss inside to prevent soil from falling out.
Old boots or shoes: A quirky choice for outdoor or sheltered porch plants. Drill drainage holes.
Baskets: As mentioned, use woven baskets as cachepots for plants in nursery pots.
DIY Planters:
Painted terra cotta pots: Buy plain terracotta pots and let your artistic side shine by painting them with acrylic paints. Seal them with a clear sealant for durability.
Macrame plant hangers: Create a beautiful way to display hanging plants. This is a great way to save surface space.
Wooden planters: Build simple boxes from wood scraps for larger plants or herb gardens. Ensure the wood is treated or lined to prevent rot. For ideas, check out resources on building simple wooden planters from sites like Family Handyman.

Considerations for Specific Plant Types

Different plants have different needs, and their ideal planter might vary.

Succulents and Cacti: These desert dwellers absolutely must have excellent drainage and prefer to dry out completely between waterings.
Best Planters: Terracotta, unglazed ceramic, concrete, or any pot where soil dries quickly. Always ensure ample drainage holes. Shallow, wide pots are often ideal.
Herbs: Most common culinary herbs (basil, mint, parsley) like consistently moist, well-draining soil.
Best Planters: Terracotta, glazed ceramic (with drainage!), or good quality plastic pots. A planter with good breathability helps prevent fungal issues.
Vining Plants (Pothos, Philodendron, String of Pearls): These often do well in standard pots that offer good balance of moisture retention and drainage.
Best Planters: Terracotta, glazed ceramic, or plastic pots are all suitable, provided they have drainage. Hanging planters work well for vining types to allow them to trail.
Plants that like moisture (Ferns, Peace Lilies): These plants appreciate slightly more consistently damp soil but still need drainage to prevent root rot.
Best Planters: Glazed ceramic, plastic, or even self-watering planters can work well, as they help retain moisture. Ensure there are drainage holes.
Orchids: Orchids have unique aerial roots that need excellent air circulation and typically do not like to sit in wet media. They are often potted in orchid-specific media like bark chips.
Best Planters: Clear plastic pots are popular for orchids because you can see root health and moisture levels. Pots specifically designed for orchids with extra ventilation slits are also ideal.

It’s always best to research the specific needs of your plant! For example, the Royal Horticultural Society (RHS) offers extensive growing advice for many plants.

Planter Placement and Its Impact

Even the perfect planter needs to be placed where your plant can thrive. Light and temperature play a role in how quickly soil dries out.

Sunlight: Planters placed in direct sunlight will dry out much faster than those in shady spots. Metal and dark-colored pots can become very hot in the sun, potentially harming roots.
Temperature and Humidity: Warmer rooms and lower humidity will cause soil to dry out quicker. Colder, more humid areas will slow drying.
Airflow: Good air circulation around the plant and the pot helps prevent fungal diseases and aids in drying. Avoid cramming plants too close together.

Q1: What is a cachepot and how do I use it?
A1: A cachepot is a decorative outer pot without drainage holes. You place your plant, still in its plastic nursery pot (with drainage!), inside the cachepot. Water the plant thoroughly over a sink or tub, let it drain completely, and then return it to the cachepot. This protects furniture and floors from water damage while allowing your plant to have good drainage.
Q2: Should I always use a pot with drainage holes?
A2: Yes, for the health of your plant, it’s almost always essential to use a pot with drainage holes. If your decorative pot doesn’t have them, use it as a cachepot or drill holes yourself if possible. Without drainage, roots are at high risk of rotting.
Q3: How often should I repot my indoor plants into new planters?
A3: Most indoor plants benefit from repotting every 1-2 years, typically in the spring. You’ll know it’s time when you see roots emerging from drainage holes, the plant dries out very quickly, or its growth has stalled.
Q4: Can I reuse old planters?
A4: Absolutely! Just make sure to thoroughly clean and disinfect old planters before use. Scrub them well with soap and water, and then soak them in a solution of 1 part bleach to 9 parts water for about 30 minutes. Rinse thoroughly and let them dry completely. This prevents the spread of diseases or pests.
Q5: What’s the best planter material for someone who tends to overwater?
A5: If you tend to overwater, porous materials like unglazed terracotta or concrete are excellent choices. They allow excess moisture to evaporate from the sides, helping the soil dry out faster and providing a buffer against overwatering.
* Q6: Do lightweight plastic pots cause problems for tall or top-heavy plants?
A6: Yes, lightweight plastic pots can sometimes lack the stability needed for tall or top-heavy plants, making them prone to tipping over. In such cases, consider using a heavier pot (like terracotta or ceramic), placing stones at the bottom of the plastic pot for added weight, or using a decorative cachepot for stability.
