Perennials are a popular choice in gardens for their stunning blooms and ease of care.
However, not everyone has the outdoor space to grow perennials effectively, and that’s where container gardening comes in handy.
In this guide, I will explore how to grow perennials in containers, from choosing the right container and soil to planting, watering, and caring for your plants.
You’ll be able to enjoy a beautiful array of flowers that will brighten up your garden or outdoor space all year round with this guide.
So let’s dive right in!
Choosing the correct container is incredibly important to the success of your perennial garden. The right container will ensure that your plants remain healthy and strong.
When selecting a container, you should consider the size and growth habit of your chosen plants. Larger plants with deeper root systems require larger pots. Be aware that some perennials have large taproots, while others have shallow, fibrous root systems.
The best container materials are porous, allowing water to evaporate through the pot, which helps to avoid over-watering your plants. Containers made of clay, concrete, or terracotta are excellent choices for perennials. Plastic containers are not ideal as they do not allow roots to breathe.
When selecting a container, also consider the climate you live in. If you live in a hot or dry climate, you’ll want to select a pot that will not dry out quickly. Conversely, if you live in a climate that experiences a lot of rain and moisture, go for a pot that has good drainage holes to avoid waterlogging your plants.
When making a container selection for your perennials, ensure that the container is the correct size, made of the right material, and suitable for the climate you live in. This will ensure that your perennials remain healthy, growing year in and year out.
Choosing the right soil is critical to the success of growing perennials in containers. Good soil ensures that your plants get the nutrients they need to grow and thrive. In this section, I’ll explain what soil perennials need, the types of soil for perennials, and the ingredients to include when making soil for perennials.
To make sure your perennials grow as they should, consider their soil needs. They prefer a light, well-draining soil, rich with organic matter. A soil blend that drains easily, retains moisture, and contains essential plant nutrients.
The best soil types for container-grown perennials are soilless mixes such as peat-based mixtures, which are rich in organic matter and hold moisture well. They drain well and keep the roots aerated. Keeping the roots oxygenated is crucial since water can drain through the bottom of the container.
At minimum, your soil mixture should contain compost, perlite, and peat moss. These ingredients work together to provide the drainage and moisture retention that perennials in containers demand. One tried and true mix to use for perennials is a blend of compost, perlite, and peat moss in equal parts (1:1:1).
When making your soil mix, you can also consider adding slow-release fertilizer pellets, which will ensure that your plants get the necessary nutrients over time. You can also add a little sand if the soil mixture is too heavy for the containers.
Making your soil mixture is not as hard as it may look. If you want, you can opt to buy pre-made soilless mixes, which are available at many home improvement stores. However, it is always wise to have your mixture since mixing your own soil mixture allows you to customize the mix to suit your plant and container’s specific needs.
Go ahead and mix in the ingredients until the soil is well blended. It’s always good to have some extra soil mix available for replenishing the containers. You can store it in a cardboard box in a dry place until needed.
The right soil is crucial for container-grown perennials’ health and well-being. So, take the time to make the perfect soil mix for your perennials in containers.
Choosing the right perennials is the most crucial aspect of container gardening. The wrong choice can lead to a disaster that could discourage even the most experienced gardeners. When it comes to container gardening, the perennials you choose should be capable of thriving in a restricted space.
Perennials that thrive in containers are those that are compact, slow-growing, and have reduced moisture requirements. Succulents such as sedum, hens, and chicks are an excellent choice for container growing because they store water in their leaves and stems, enabling them to survive prolonged periods of drought.
Herbs and vegetables such as thyme, parsley, lettuce, and radish are also great options. They are shallow-rooted perennials that stay small enough to fit in a container and have the extra perk of being edible.
When selecting perennials for container gardening, it’s essential to consider their flowering time. Choosing perennials that bloom at different times of the year will ensure that you have continuous blooms throughout the growing season.
For instance, start with perennials that bloom early in the season like daffodils then switch them out with later blooming perennials like peonies. This simple practice ensures that you have a visually appealing garden throughout the year.
When selecting perennials, remember to choose the best size and growth habit for the container. Select plants that will have sufficient space to grow in the container you plan to use. Also, consider the primary goal of the container garden. Mixing perennials with grasses and foliage plants is an excellent way of building a low maintenance garden.
When you have a limited amount of space or time for gardening, container gardening is the perfect alternative. By selecting the right perennials for your container garden, you can deliver stunning results with minimal effort.
Once you’ve chosen the perfect container, soil mixture, and the right perennial plants, you’re ready to plant them. Proper planting is key to the health and vitality of your container perennials.
To begin, fill your container about two-thirds full with your soil mixture, being sure to leave enough space on top for your plants. Remove your plants from their original containers, and loosen the soil around the root ball. This will encourage the roots to grow outward, rather than continuing in the circular shape of the original container.
Next, place your plants on top of the soil in the container, and fill in around them with more soil mixture. Be sure to tamp the soil down around each plant to remove any air pockets.
It’s important to avoid planting your perennials too deeply, as this can lead to rot. As a general rule, the top of the root ball should be level with the surface of the soil in your container.
After planting, give your new container garden a thorough watering. Be sure to use enough water to allow it to soak through the soil and reach the roots of your plants.
At this point, your perennials may look somewhat droopy, but don’t worry – they should bounce back within a day or two. Just be sure to keep an eye on them in the coming days and water as necessary, being careful not to overwater.
Now that your perennials are successfully planted in their container home, it’s time to enjoy watching them grow and bloom throughout the season.
Caring for container perennials is essential for ensuring healthy and vibrant blooms. Here are some key things to keep in mind:
Firstly, watering is important. Container perennials require regular watering, especially during hot weather. It’s important to keep the soil evenly moist, but not waterlogged. You can check the moisture level by sticking your finger an inch deep into the soil. If it feels dry, then it’s time to water.
Secondly, fertilizing is key. Since perennials in containers are dependent on you for nutrients, feeding them is important to support growth and flowering. Consider using a slow-release fertilizer or liquid fertilizer according to the plant’s needs.
Lastly, pests and diseases can be problematic. Regularly inspect your container perennials for signs of aphids, spider mites, or powdery mildew. If you notice any, take action right away. You can use insecticidal soap or neem oil to rinse off the pests or hire a professional if the problem is severe.
In conclusion, I hope this guide has given you a better understanding of growing perennials in containers.
As I explained in the article, container gardening offers multiple benefits such as having the flexibility to move the plants indoors, limited space gardening, and many more.
My favorite part of container gardening is the magic and satisfaction of watching these plants grow and bloom.
