How Many Plants per Container: An Essential Gardening Guide
How Many Plants per Container?
The number of plants per container depends on the size of the container and the type of plants being used.
As a general guideline, it is recommended to have three or four plants in 10 to 12-inch planters, four to six plants in 14 to 16-inch planters, and six to eight plants in 16 to 20-inch planters.
However, this can vary based on the vigor and size of the plants.
For example, compact plants may require fewer plants in a container, while spreading plants like Supertunia Petunias may need only three plants in a 14-inch container.
It is important to leave space between the edge of the container and the root ball of the plants, and to consider the growth and size of the plants being used.
Key Points:
- Number of plants per container depends on container size and plant type
- General guideline: 3-4 plants in 10-12 inch planters, 4-6 plants in 14-16 inch planters, 6-8 plants in 16-20 inch planters
- The number of plants can vary based on plant vigor and size

Did You Know?
1. Did you know that the concept of growing multiple plants in a single container dates back to ancient civilizations? Early civilizations like the Babylonians and Egyptians used this technique to maximize their agricultural output and conserve valuable space.
2. Contrary to popular belief, the number of plants you should grow per container depends on the type of crops and their root system. For instance, leafy greens like lettuce or spinach can be densely planted, while plants with larger root systems like tomatoes or peppers require more space to grow and should be given their own containers.
3. When growing multiple plants in one container, it’s important to consider their compatibility. Some plants have competing growth patterns or nutrient requirements, which can negatively impact their performance and overall health. Researching companion planting charts or consulting with gardening experts can help determine good plant combinations.
4. The technique of growing multiple plants in a single container is often referred to as “container gardening,” “pot-in-pot gardening,” or “companion planting.” It has gained popularity in urban areas where space is limited, allowing individuals to cultivate a variety of crops in a small area.
5. Container gardening is not limited to outdoor spaces; it can also be done indoors, making it a great option for those with limited access to a garden. Indoor container gardening provides an opportunity to bring nature into your home and enjoy the benefits of growing your own fresh produce year-round.
Two Basic Ways To Plant A Combination
When it comes to planting a combination of plants in a container, there are two basic approaches: the living flower arrangement and traditional planting. The living flower arrangement involves packing the container with multiple plants, creating an instant and lush appearance. However, this method may result in less longevity and more disease problems due to the crowded conditions. On the other hand, traditional planting allows for more space between the plants, promoting healthier growth and longer bloom periods.
Recommended Number Of Plants Per Container
While there are no definitive rules on the exact number of plants to include in a container, there are general guidelines that can help. In 10 to 12-inch planters, it is recommended to include three or four plants. For slightly larger planters, such as 14 to 16-inch ones, four to six plants can be used. If you have an even larger container, around 16 to 20 inches, it is best to aim for six to eight plants. These recommendations can be adjusted based on the vigor and size of the plants being used.
For instance, certain plants like Supertunia Petunias tend to spread, so it is advised to limit the number of plants in a container. In the case of a 14-inch container, it is recommended to have only three Supertunia Petunias. Even larger planters can accommodate only three plants of the vigorous Supertunia Vista Petunias. It is essential to consider the growth habits of specific plants and adjust the number accordingly.
Compact plants typically require fewer plants in a container due to their smaller size. Keep this in mind when planning the arrangement of your plants.
Adjusting Number Of Plants Based On Vigor And Size
When determining the number of plants to include in a container, it is crucial to consider the vigor and size of the plants. Vigorous plants tend to have a more expansive growth habit, so including fewer plants will allow them to have sufficient space to thrive. Likewise, larger plants require more room to grow and develop.
By adjusting the number of plants based on these factors, you can ensure that each plant has the space it needs to reach its full potential.
To get an idea of the final size and vigor of a plant, refer to the spacing information on the plant tags. This information will help you estimate how much space each plant requires and how it will grow over time. By taking this into account, you can make informed decisions regarding the number of plants to include in your container.
– Consider the vigor and size of the plants
– Vigorous plants need more space to grow
– Larger plants require more room to develop
– Adjust the number of plants based on these factors
– Refer to spacing information on plant tags to estimate growth
– Make informed decisions about the number of plants to include in your container
Arrangement Suggestions For Different Container Shapes
The shape of your container can influence the arrangement of plants. For semi-circular containers, consider placing taller plants in the back to create depth, with shorter plants in the front. This arrangement maximizes the visual impact of your container garden.
When dealing with round or square containers, it is best to place taller plants in the center and surround them with shorter plants around the edges. This arrangement creates a balanced and aesthetically pleasing display.
Oblong or rectangular containers offer more space for creativity. To create a harmonious arrangement, consider placing taller plants in the middle and shorter plants toward the sides. This arrangement ensures that each plant receives adequate sunlight and grow space.
Considering Size And Growth Of Plants And Leaving Headspace
When planting in containers, it is essential to leave space between the edge of the container and the root balls of the plants. This space allows for proper air circulation, preventing diseases that may occur from overcrowding. It also allows for easier watering and maintenance.
Considering the size and growth of the plants being used is critical when planning the number of plants per container. Keep in mind that plants will grow and spread over time. By factoring in this growth, you can ensure that the plants have enough space to develop fully.
Finally, it is important to leave some headspace between the top of the soil and the edge of the pot. This extra space prevents soil loss when watering and helps channel water into the container, ensuring that it reaches the roots of the plants effectively.
there are no definitive answers on how many plants to include in a container. However, by following the guidelines mentioned above, you can make informed decisions about the number of plants per container. Consider the vigor and size of the plants, the shape of the container, and leave appropriate space for growth. With these considerations in mind, you can create beautiful and thriving container gardens for your outdoor space.
- Leave space between the edge of the container and the root balls of the plants.
- Consider the size and growth of the plants when planning the number of plants per container.
- Leave headspace between the top of the soil and the edge of the pot.
- Make informed decisions about the number of plants per container by considering the vigor and size of the plants and leaving appropriate space for growth.

Frequently Asked Questions
Can you put too many plants in a planter?
When it comes to planters, less can sometimes be more. Overcrowding a planter with too many plants can have detrimental effects on their growth and overall health. As Reese points out, plants will compete for essential resources such as nutrients, water, and light. When resources become limited due to overcrowding, the plants may struggle to access what they need to thrive, leading to stunted growth or even death. It’s essential to provide each plant with enough space and resources to ensure their optimal growth and well-being.
How many plants should I put in a hanging basket?
When it comes to hanging baskets, the number of plants you should put depends on the size and type of plants. As a general rule, one plant per inch of basket diameter works well. For instance, a 12 inch basket would typically require 12 plants. However, larger plants such as Geraniums, Surfinia Petunias, culinary herbs, and Fuchsias can be spaced out a bit more, and around 5 plants may be suitable for a 12 inch hanging basket.
How big is a 10 plant container?
A 10 plant container typically refers to a pot with a diameter of 10 inches, which translates to a container volume of approximately 2.5 to 3 gallons. This size is suitable for growing a single plant and provides enough space for the roots to spread and acquire necessary nutrients. It allows for adequate water and soil retention, ensuring the plant’s healthy development while offering a convenient size for handling and positioning.
Is it OK to have a lot of plants?
Having a lot of plants in your home is not only okay but can also have numerous benefits. Research has revealed that specific houseplants excel in purifying the air, as indicated by NASA’s houseplant list. While NASA suggests 15-18 houseplants for a 1,800 square-foot house, even having a few plants can be highly effective. These plants act as natural air purifiers, removing toxins and improving indoor air quality. Thus, having a significant number of plants not only adds aesthetic appeal but also contributes to a healthier living environment.
