We’ll walk through all the important bits, from drainage to materials, so you can confidently choose the perfect planter. Let’s get your plants settled into their new, beautiful homes!
The Crucial Role of a Plant Planter
Think of a planter as more than just a pot. It’s the foundation of your indoor plant’s life. It holds the soil, of course, but it also plays a vital role in drainage, aeration, and even the overall health of your plant’s roots. A good planter helps prevent common issues like root rot, ensures your plant gets enough air, and keeps it stable as it grows. Choosing the right one is a foundational step, setting your plant up for success before you even bring it home. It’s about creating an environment where your plant can thrive, not just survive. Let’s dive into what makes a planter truly great.
Key Considerations When Choosing a Planter
When you’re on the hunt for the ideal planter for your indoor plants, keep these essentials in mind. They might seem simple, but they make a world of difference to your plant’s well-being.
1. Drainage is Non-Negotiable
This is, without a doubt, the most important feature. Your planter absolutely must have drainage holes at the bottom. Why? Plants need their roots to breathe. When water sits around the roots for too long, it suffocates them and creates a breeding ground for harmful bacteria and fungi, leading to root rot. This is a silent killer for many houseplants.
- Why drainage is key: Prevents waterlogging, allows roots to get oxygen, reduces the risk of root rot.
- What to look for: Holes at the bottom of the pot. If a decorative pot doesn’t have them, you’ll need to place a “grow pot” (a pot with drainage) inside it or drill holes yourself (which can be tricky depending on the material).
Some planters come with a saucer to catch excess water. While this is helpful to protect your surfaces, ensure the plant isn’t sitting in a pool of water in the saucer after watering. You might need to empty it a few minutes after watering.
2. Size Matters: The Right Fit for Your Plant
Choosing the correct size planter is like giving your plant enough room to grow without being overwhelmed. A pot that’s too small will quickly become root-bound, meaning the roots have no more space to grow and can start circling, hindering nutrient and water uptake. On the other hand, a pot that’s too large can hold too much moisture, again increasing the risk of root rot, as the soil takes a long time to dry out.
- Too small: Limits root growth, leads to quick drying, can cause root-bound issues.
- Too big: Holds excess moisture, increases risk of root rot, can stifle growth until roots fill the space.
General Rule of Thumb: When repotting, choose a planter that is 1-2 inches larger in diameter than the current pot. This usually provides enough extra space for a couple of years of growth.
3. Material: Porous vs. Non-Porous
The material of your planter affects how quickly the soil dries out and how much moisture it retains. This is particularly important for plants with different watering needs.
Porous Materials (Allow air and moisture to pass through):
- Terracotta/Clay: These are classic for a reason! Terracotta breathes exceptionally well, allowing excess moisture to evaporate through the pot walls. This is fantastic for plants that prefer to dry out between waterings, like succulents, cacti, and many orchids. The downside is that they dry out faster, so plants that like consistent moisture might not be as happy. They are also fragile and can break.
- Concrete: Similar to clay, concrete is porous and heavier. It offers good drainage but can also dry out soil relatively quickly. Its weight makes it great for larger plants that need stability.
- Untempered/Unsealed Ceramic: Some unglazed ceramics are porous. However, most decorative ceramic pots are glazed inside and out.
Non-Porous Materials (Retain moisture):
- Glazed Ceramic: These pots are coated with a glassy finish, preventing moisture from escaping through the sides. They retain moisture much longer than terracotta, making them ideal for plants that like consistently moist soil, such as ferns, peace lilies, and African violets. Be extra careful not to overwater.
- Plastic: Lightweight, inexpensive, and durable, plastic pots are a popular choice. They hold moisture well, which can be a pro for thirsty plants but a con for those prone to overwatering. They are great for starting seeds or for plants that really don’t like drying out.
- Metal: Metal planters, especially those without any protective coating, can rust. They also conduct heat, which can be problematic for roots on warm days. They generally don’t breathe well and retain moisture.
- Glass: Often used for decorative purposes or in terrariums, glass offers no drainage unless specifically designed for it. It completely seals in moisture, making it suitable only for specific setups or plants accustomed to very wet conditions, and even then, it’s risky.
4. Style vs. Substance: Aesthetics and Your Home
While plant health comes first, we also want our planters to look good! Your planter is a decorative element in your home. Think about the overall style and color scheme of the room where the plant will live. Consider:
- Color: Neutrals like white, grey, and black go with everything. Bold colors can make a statement. Earthy tones complement natural greenery.
- Texture: Smooth, ribbed, woven, or hammered – textures add visual interest.
- Shape: Tall and slender, short and squat, geometric – the shape can complement the plant’s form.
- Weight: If you have pets or children who might knock things over, a heavier pot like ceramic or concrete is a safer bet.
Remember, you can always place a stylish plastic or terracotta pot inside a more decorative cachepot (a pot without drainage used for looks) to hide the functional pot and maintain proper drainage. Just ensure the inner pot isn’t constantly sitting in water collecting at the bottom of the cachepot.
Types of Planters and Their Uses
Let’s explore some common planter types and when they are best used. Understanding their features will help you make the right choice for your specific plants.
Self-Watering Planters
These are a game-changer for busy plant parents or for anyone who struggles with watering schedules. Self-watering planters have a reservoir at the bottom that holds water. A wicking system (often a wick or a porous material) draws water up into the soil as the plant needs it. This provides a consistent moisture level without the risk of overwatering if managed correctly.
- Pros: Excellent for consistent moisture, reduces watering frequency, prevents overwatering (if reservoir isn’t kept constantly full).
- Cons: Can be more expensive, can lead to salt/mineral buildup over time, might not be suitable for plants that need their soil to dry out completely.

Standard Pots (Terracotta, Plastic, Glazed Ceramic)
These are the most common types of pots you’ll find. As discussed earlier, their suitability depends heavily on material and the plant’s needs.
- Terracotta: Best for drought-tolerant plants or those prone to root rot.
- Plastic: Versatile, good for moisture-loving plants, lightweight, affordable.
- Glazed Ceramic: Good for moisture-loving plants, heavy, wide variety of aesthetics.
Hanging Planters
Perfect for adding vertical interest to your home or for small-space gardening, hanging planters are simply pots designed to be suspended. They can be made from various materials and come in many styles.
- Pros: Space-saving, decorative, good for trailing plants.
- Cons: Watering can be a bit trickier (you need to bring them down or have a watering can with a long spout), drainage is still essential.
Ensure your hanging system is robust enough to support the weight of the planter, soil, and plant, especially when watered.
Cachepots
These are decorative pots or containers designed without drainage holes. Their primary purpose is to hide a functional pot (one with drainage) and enhance the aesthetic of your plant display. They are excellent for disguising less attractive plastic nursery pots.
- Pros: Highly decorative, hides unsightly pots, adds a designer touch.
- Cons: Must be used with a separate inner pot that has drainage. Without it, you risk root rot as water has nowhere to go.
When using a cachepot, always ensure there’s a gap between the bottom of the inner pot and the bottom of the cachepot, or remove excess water from the cachepot shortly after watering the plant.
Window Boxes and Troughs
These are typically long, rectangular planters designed to sit on windowsills, shelves, or railings. They are great for growing multiple smaller plants or a collection of herbs together.
- Pros: Can house multiple plants, good for herbs and annuals, can add greenery to ledges.
- Cons: Drainage can be a challenge if holes are insufficient, can be heavy when filled.
When planting multiple plants together, consider their light and water needs to ensure they are compatible companions. For more on container gardening, the Royal Horticultural Society (RHS) offers great advice on choosing containers and planting.
Planter Size Guide: What’s the Sweet Spot?
Here’s a handy table to help you visualize planter sizing relative to your plant’s current pot.
| Current Pot Diameter | Recommended New Planter Diameter | Ideal Use Case |
|---|---|---|
| 3-4 inches | 5-6 inches | Small houseplants, starter plants, herbs. |
| 5-6 inches | 7-8 inches | Younger or medium-sized houseplants. |
| 7-8 inches | 9-10 inches | Mature houseplants before they become root-bound. |
| 9-10 inches | 11-12 inches | Larger, well-established houseplants. |
| 12 inches and larger | 13-14 inches (or 2-4 inches larger than current) | Very large or fast-growing plants. |
Remember this is a guideline. If your plant is root-bound (roots are circling tightly around the soil ball or growing out of drainage holes), it’s time to upsize. If the soil feels constantly waterlogged and the plant isn’t growing, the pot might be too large.
Common Indoor Plant Planter Mistakes to Avoid
Even with the best intentions, we can sometimes make a few missteps when choosing planters. Let’s look at the most common ones so you can steer clear!
- Forgetting Drainage Holes: This is number one! A pot without holes is a recipe for disaster for most plants.
- Over-Potting: Choosing a planter that is way too big. More soil means more water retention, which is dangerous.
- Under-Potting: Using a pot that’s too small. This restricts growth and can lead to the plant drying out too quickly.
- Ignoring Plant Needs: Planting a succulent in a heavy plastic pot that holds too much moisture, or a fern in a fast-drying terracotta pot. Match the pot to the plant!
- Using Decorative Pots without a Grow Pot: Relying solely on a cachepot without an inner pot with drainage holes is a common and detrimental mistake.
DIY Planters on a Budget
Getting creative with what you have can be incredibly rewarding and budget-friendly! Many everyday items can be transformed into charming planters.
- Tin Cans: Clean out empty food cans (soup, beans, coffee). Remove any sharp edges. Drill or punch drainage holes in the bottom. Decorate them with paint, twine, or fabric scraps.
- Plastic Containers: Large yogurt tubs, ice cream containers, or even old plastic storage bins can work. Ensure they are food-grade if you plan to grow edibles like herbs. Again, drainage holes are a must!
- Old Mugs or Teacups: For small plants like succulents or air plants, a cute mug or teacup can be perfect. You’ll need a special diamond drill bit designed for ceramic/glass to drill drainage holes. Be very gentle!
- Repurposed Bags: Sturdy fabric tote bags or even heavy-duty grocery bags can be used, especially for herbs or temporary plantings. Ensure they have good drainage (some fabrics allow water to weep through).
- Wooden Crates/Boxes: Small wooden crates, wine boxes, or even old drawers can be lined with plastic (with drainage holes added to the plastic) or used as outer decorative containers for nursery pots.
Important note for DIY: Always ensure whatever vessel you choose can have drainage holes added safely and effectively. If you’re unsure about drilling into certain materials, it’s better to stick to using it as a decorative cachepot for a plant in a standard pot with drainage.
Frequently Asked Questions (FAQ)
Q1: Do all indoor plants need drainage holes?
A1: For the vast majority of indoor plants, yes, drainage holes are essential. They prevent water from sitting around the roots, which can cause root rot. Some exceptions exist for specific setups like very established terrariums or hydroponic systems, but for typical potted plants, drainage is key.
Q2: How do I know if my plant is root-bound?
A2: Signs of a root-bound plant include roots visible growing out of the drainage holes, roots circling tightly around the soil ball, water draining through the pot almost immediately after watering, and stunted plant growth. If you see these signs, it’s likely time to repot into a slightly larger planter.
Q3: Can I use rocks or gravel at the bottom of a pot for drainage?
A3: No, adding a layer of rocks or gravel at the bottom of a pot without drainage holes does not improve drainage. In fact, it can create a perched water table, actually holding water even higher up in the soil, making root rot more likely. Drainage holes are the only effective way to ensure proper drainage.
Q4: How often should I repot my plants?
A4: Most houseplants benefit from repotting every 1-2 years. You should repot when the plant becomes root-bound, the soil is depleted, or the plant has outgrown its current container. Spring is generally the best time to repot as plants are entering their active growth phase.
Q5: What’s the difference between a planter and a pot?
A5: Often, the terms are used interchangeably. However, “pot” generally refers to the container a plant grows in, typically with drainage. “Planter” can be a broader term, sometimes referring to decorative containers or larger vessels for multiple plants. A cachepot is a decorative planter meant to hold a pot with drainage.
Q6: My planter has drainage holes, but my plant still seems to be suffering. What else could be wrong?
A6: While drainage is crucial, a plant’s health depends on many factors. Ensure your plant is receiving the correct amount of light, is being watered appropriately for its species, has good soil, and is protected from pests. Sometimes, issues like over-fertilizing or temperature fluctuations can also cause problems.
