Container Gardening in September: Choosing the Right Pot
Container Gardening in September: Choosing the Right Pot for Your Plants
September is a season of change in the garden.
Summer plants may be slowing down, fall crops may be ready to start, and some container plants may have outgrown the pots they were placed in earlier in the year. At the same time, changing temperatures, sunlight, rainfall, and humidity can affect how quickly containers dry out.
That makes September a smart time to take a closer look at your containers and ask:
Is this pot really right for the plant?
Choosing the right container is about more than appearance. The right pot should provide enough room for the plant's roots, allow appropriate drainage, work well with the growing medium, and fit the space where the plant will grow.
Whether you're gardening on a balcony, patio, porch, greenhouse, or indoors, choosing the right container can make plant care easier and give your plants a better growing environment.
Why Container Choice Matters in September
A container does much more than hold a plant.
It influences:
- Available root space
- Drainage
- Moisture retention
- Air around the roots
- Plant stability
- Watering frequency
- Mobility
- How much growing medium you need
Grow It Depot's September planting guide also recommends considering container size, drainage, plant root requirements, growing medium, sunlight, and watering needs when growing plants in containers.
September is also a useful time to inspect containers after a long summer growing season.
You may find that:
- A plant has outgrown its pot
- A fabric container needs replacing
- Drainage holes are blocked
- Growing media needs refreshing
- A container is no longer suitable for the plant
- You need different pot sizes for new fall crops
The Basic Rule
Choose the container for the plant—not simply because the pot looks attractive or happens to be available.
How to Choose the Right Pot Size
Pot size is one of the most important decisions in container gardening.
The right size depends on the plant's root system, mature size, growth habit, and how long you expect it to remain in the container.
A Pot That Is Too Small
A container may become too small when:
- Roots have filled much of the available space
- Roots are coming through drainage holes
- The growing medium dries unusually quickly
- The plant becomes unstable
- Growth appears restricted
- The plant needs very frequent watering
A Pot That Is Too Large
Bigger is not automatically better.
An unnecessarily large container can:
- Require much more growing medium
- Become difficult to move
- Become very heavy after watering
- Take up valuable growing space
- Make moisture management more difficult for some small plants
Beginner Tip
When moving a plant into a larger container, don't automatically choose the biggest pot you can find.
Choose an appropriate size based on the plant's root system and expected growth.
Container Size Guide by Plant Type
| Plant Type | Container Consideration | Important Feature |
|---|---|---|
| Leafy greens | Moderate root space | Width and drainage |
| Herbs | Small to moderate, depending on variety | Drainage |
| Radishes | Enough depth for roots | Container depth |
| Flowers | Depends on mature size | Width and stability |
| Strawberries | Adequate root space | Drainage and sunlight |
| Small vegetables | Moderate to larger container | Root space |
| Fruit plants | Larger, stable container | Root space and support |
| Shrubs | Large container | Stability and drainage |
| Small trees | Very large container | Root space and stability |
| Indoor plants | Match container to root system | Drainage and manageable size |
Always check the growing requirements of the specific plant or variety before choosing a container.

Drainage: The Feature You Should Never Ignore
A beautiful pot is not necessarily a good plant pot.
For most traditional container-growing situations, excess water needs a way to leave the container.
Poor drainage can keep the root zone excessively wet and create stressful growing conditions.
Before planting, check:
- Are there drainage holes?
- Are the holes open?
- Can excess water escape freely?
- Is the container sitting somewhere water can collect?
- Does the growing medium drain appropriately?
- Is the saucer holding standing water?
Grow It Depot's September garden-reset guide also recommends checking containers, drainage, growing media, and watering equipment during the seasonal transition.
What About Pot Saucers?
A saucer can be useful for containers placed on:
- Patios
- Balconies
- Porches
- Indoor floors
- Greenhouse benches
The important thing is to avoid keeping the plant sitting in standing water for long periods.
Grow It Depot carries Grow1 pot saucers in different sizes that can be matched to compatible containers.

Fabric Pots: A Flexible Option for Container Growers
Fabric pots are a popular choice for many container gardeners.
Grow It Depot's Pots & Containers collection includes fabric pots and grow bags in a variety of sizes. The collection describes these products as options designed around root aeration and drainage for indoor and outdoor growing.
One option is the Hydrofarm Dirt Pot Flexible Portable Planter, available in different versions, including a model with handles.
Why Consider a Fabric Pot?
Depending on your growing setup, fabric containers can offer:
- Flexible construction
- Good drainage characteristics
- Air exposure around the root zone
- Easy storage when empty
- Different size options
Grow It Depot also carries Grow1 Fabric Pots, Root Pouch containers, and other fabric grow bags.

September Tip
If you already use fabric pots, inspect them after the summer season.
Check for:
- Torn fabric
- Damaged seams
- Root buildup
- Poor drainage
- Excess debris
- General structural damage
Replace containers that are no longer suitable for your growing setup.
Plastic, Terracotta, Ceramic, or Fabric?
There is no single container material that is best for every garden.
The right choice depends on the plant, growing environment, watering routine, and how often you need to move the container.
| Container Type | Advantages | Things to Consider |
|---|---|---|
| Fabric | Flexible and breathable | May require closer moisture monitoring |
| Plastic | Lightweight and practical | Drainage design is important |
| Terracotta | Traditional and porous | Can dry more quickly |
| Ceramic | Decorative and stable | Can be heavy |
| Nursery pots | Practical and easy to use | Choose the correct size and drainage |
| Self-watering containers | Can simplify watering in some setups | More parts to maintain |
Think About Your Growing Location
For example:
Balcony:
Choose containers that are manageable and easy to move.
Patio:
You have more flexibility with container size but should still consider final weight.
Greenhouse:
Focus on drainage, plant spacing, airflow, and efficient watering.
Indoor:
Choose containers that are easy to manage and protect floors with suitable trays or saucers.
Match the Pot to the Root System
The part of the plant you see above the growing medium is only half the story.
Roots need enough room to grow and access to moisture, oxygen, and a suitable growing environment.
Some plants have relatively shallow root systems, while others need more depth or volume.
Shallow-Rooted Plants
Some leafy greens, herbs, and flowers may perform well in containers that provide adequate width without excessive depth.
Deeper-Rooted Plants
Root vegetables, larger vegetables, fruit plants, shrubs, and young trees may require considerably more depth and container volume.
Always check the requirements of the individual plant rather than relying only on a general container rule.
Don't Forget the Growing Medium
A good container and a suitable growing medium work together.
The growing medium should provide an appropriate balance of:
- Moisture
- Air
- Drainage
- Root support
Different plants and growing systems can require different media.
Grow It Depot currently carries Mother Earth Coco + Perlite Mix, a 70% coco and 30% perlite growing medium. The product listing describes it as an alternative to traditional potting media and highlights aeration and drainage characteristics.
Shop Mother Earth Coco + Perlite Mix
Why Coco + Perlite?
Coco provides a moisture-holding component, while perlite contributes air space and drainage.
However, this does not mean the mix is automatically suitable for every plant.
Choose your growing medium according to:
- Plant requirements
- Growing method
- Watering system
- Nutrient program
- Container size
- Local conditions

Grow It Depot also offers other growing-media options for different growing systems.
How Container Material Can Change Watering
Container plants can dry at different rates depending on:
- Pot material
- Container size
- Plant size
- Growing medium
- Sun exposure
- Temperature
- Wind
- Humidity
- Rainfall
A small container in direct sun may dry much faster than a large container in partial shade.
September can also bring different conditions from midsummer.
That means you should not automatically continue the exact watering schedule you used during summer.
Instead:
- Check the growing medium.
- Consider recent rainfall.
- Look at the plant.
- Consider temperature and sunlight.
- Water according to the plant's needs.
Water according to conditions—not simply according to the calendar.
Container Gardening in September: What Can You Grow?
Depending on your local climate and planting window, September can be a useful month for starting or refreshing containers.
Possible options include:
- Lettuce
- Spinach
- Herbs
- Radishes
- Fall flowers
- Smaller vegetables
- Strawberries
- Ornamental plants
Grow It Depot's September planting guide covers many of these container-friendly options and emphasizes choosing plants according to local climate and growing conditions.
Remember Your Local Climate
September planting recommendations are not the same everywhere.
Consider:
- USDA hardiness zone
- Local temperatures
- Frost risk
- Sunlight
- Rainfall
- Length of the growing season
Plant for your climate, not simply for the month on the calendar.
Growing Strawberries in Containers
Strawberries are a good example of why choosing the right container matters.
Grow It Depot currently lists Jayme Garden Dwarf Strawberry Seeds, which the product listing describes as a compact strawberry variety suitable for container gardening, patios, hanging baskets, and outdoor garden spaces. The listing specifies full sun, well-draining fertile soil, moderate watering, and USDA Zones 4–8.
Shop Jayme Garden Dwarf Strawberry Seeds
For container-grown strawberries, pay attention to:
- Adequate root space
- Good drainage
- Sunlight
- Suitable growing medium
- Consistent moisture
- Container stability
A Useful September Shopping Tip
If you are buying a plant or seeds specifically for a container garden, choose the plant first and then select the container around its requirements.
This prevents a common mistake: buying an attractive pot that is not suitable for the plant.
Growing Larger Plants in Containers
Container gardening isn't limited to herbs and small vegetables.
Some compact or columnar fruit plants can also be grown in suitable large containers.
Grow It Depot currently lists Jayme Garden's White Icicle Columnar Apple Tree, with the product listing describing it as suitable for large pots and patio growing. The listing gives a mature height of 8–10 feet and a mature spread of 2–3 feet.
Shop White Icicle Columnar Apple Tree
This is an important reminder:
A plant can be suitable for container growing and still require a substantial container.
Before purchasing larger plants, consider their mature size, container requirements, support needs, and local climate.
When Should You Repot a Container Plant?
September can be a useful time to inspect plants that may have outgrown their containers.
Look for:
- Roots emerging from drainage holes
- Roots tightly circling the container
- Growing medium drying much faster than before
- Plant instability
- Restricted growth
- A container that has become too small
But don't repot simply because September has arrived.
If a plant is healthy and its current container still provides enough root space and drainage, there may be no reason to disturb it.
How to Repot a Plant Into a Larger Container
If your plant genuinely needs more room, follow these simple steps.
Step 1: Choose the New Container
Select a container appropriate for the plant's root system and expected growth.
Step 2: Check Drainage
Make sure the container has appropriate drainage.
Step 3: Prepare the Growing Medium
Use a growing medium suitable for the plant.
Step 4: Remove the Plant Carefully
Handle the plant and root system gently.
Step 5: Position the Plant
Place the plant at an appropriate depth.
Step 6: Fill Around the Root Ball
Add growing medium without excessively compacting it.
Step 7: Water as Appropriate
Water according to the plant's requirements.
Step 8: Return the Plant to the Right Location
Make sure it receives appropriate light and environmental conditions.
September Container Inspection Checklist
Before buying new pots, check the containers you already have.
Inspect Every Container
☐ Check for cracks
☐ Check drainage holes
☐ Remove old roots
☐ Check for buildup
☐ Inspect fabric for tears
☐ Clean reusable containers appropriately
☐ Check saucers and trays
☐ Look for pest activity
☐ Check the growing medium
☐ Decide whether the plant actually needs repotting
This quick inspection can save money and help prevent unnecessary purchases.
Common Container Gardening Mistakes
1. Buying the Pot Before Choosing the Plant
Start with the plant's requirements.
Then choose the container.
2. Choosing the Biggest Pot Available
More space is not automatically better.
Choose a practical size appropriate for the plant.
3. Ignoring Drainage
A decorative container with poor drainage can create root-zone problems.
4. Using the Same Growing Medium for Every Plant
Different plants can have different moisture and root-zone requirements.
5. Watering on a Fixed Schedule
Weather and plant water use change.
Check the growing medium and plant instead.
6. Forgetting Mature Size
A small starter plant can become a much larger plant.
Think ahead before selecting the container.
7. Making Containers Too Heavy
Remember that growing medium becomes heavier when wet.
Think about how you will move the container after planting.
8. Crowding Containers Together
Plants need appropriate space for light, airflow, watering, inspection, and growth.
Do & Don't: Choosing Containers
| Do | Don't |
|---|---|
| Choose the container based on the plant | Don't choose only by appearance |
| Check drainage | Don't ignore standing water |
| Consider mature plant size | Don't focus only on the starter plant |
| Choose appropriate growing media | Don't use one medium for every plant |
| Consider final container weight | Don't assume a large wet pot will be easy to move |
| Inspect existing pots | Don't replace containers unnecessarily |
| Adjust watering to conditions | Don't blindly follow a summer schedule |
| Consider sunlight | Don't ignore the plant's light requirements |
Choosing Pots for Small Spaces
Container gardening is especially useful when growing space is limited.
You can grow plants on:
- Balconies
- Patios
- Porches
- Small yards
- Rooftops
- Greenhouses
- Windowsills
- Indoor growing areas
But a small growing area does not necessarily mean you need tiny pots.
A plant with a larger root system may still require a substantial container even when it is growing on a small balcony.
A Better Question
Instead of asking:
"What is the smallest pot I can use?"
Ask:
"What is the smallest practical container that gives this plant enough room to grow well?"
This approach helps you use limited space without unnecessarily restricting your plants.

Frequently Asked Questions
What size pot is best for container gardening?
There is no single pot size that works for every plant. Choose a container based on the plant's root system, mature size, growth habit, and growing requirements.
Is a bigger pot always better?
No. An unnecessarily large pot can use more growing medium, become heavy, and make moisture management more difficult for some plants.
Are fabric pots good for container gardening?
Fabric pots can be useful for many appropriate container-growing situations. Grow It Depot's current Pots & Containers collection includes several fabric pot and grow-bag options.
Do plant pots need drainage holes?
For most traditional container-growing situations, adequate drainage is important. Specialized systems may work differently, so follow the requirements of your particular growing system.
Can I use coco and perlite for container plants?
A coco-perlite mix can be appropriate for certain plants and growing systems. Grow It Depot's Mother Earth Coco + Perlite Mix contains 70% coco and 30% perlite and is described by the manufacturer as providing aeration and drainage characteristics.
Always confirm that the medium is suitable for the plant you're growing.
Should I repot plants in September?
Only if they need it. September is a useful time to inspect containers, but a healthy plant does not need repotting simply because the season has changed.
Can strawberries grow in pots?
Yes. Suitable strawberry varieties can grow in containers when they receive appropriate root space, drainage, sunlight, moisture, and growing conditions. Grow It Depot's current Jayme Garden Dwarf Strawberry Seeds are specifically listed for container gardening and small spaces.
Can fruit trees grow in containers?
Some fruit trees can be grown in large containers when the variety, container size, growing medium, support, and climate are appropriate. Grow It Depot currently lists the White Icicle Columnar Apple Tree as suitable for large pots and patio growing.
How often should I water container plants in September?
There is no universal schedule. Check the growing medium and consider the plant, container size, temperature, rainfall, sunlight, wind, and humidity.
Should I replace my old pots?
Not necessarily. Inspect them first. If they are structurally sound, drain properly, and remain suitable for the plant, they may be reusable.
Final Thoughts
The right container can make container gardening much easier, but choosing one does not have to be complicated.
Start with the plant.
Then think about:
- Root space
- Container size
- Drainage
- Growing medium
- Sunlight
- Watering
- Mature plant size
- Container weight
- Available space
September is also a good time to inspect the pots you already have before buying new ones.
Clean reusable containers, replace damaged pots, check drainage, evaluate your growing media, and repot only when your plants actually need more room.
Whether you're growing herbs on a balcony, vegetables on a patio, strawberries in containers, or a larger plant in a substantial pot, choosing the container around the plant's needs gives you a better starting point.
