When to Plant Mums in Containers

Mums, also known as chrysanthemums, are a popular fall flower that can be grown in containers for a splash of autumn color on patios, porches, and balconies. If you're wondering when to plant mums in containers, there are a few things to keep in mind.

Choosing the Right Time

The timing of planting mums in containers depends on whether you want them to bloom in the fall or the following spring. If you want to enjoy blooms in the fall, plant your mums in containers in the late summer or early fall. This will give them enough time to establish roots and start blooming before the colder temperatures set in. If, on the other hand, you want to use the mums as perennials and have them come back year after year, plant them in the springtime after the last frost has passed.

Selecting the Right Container

When planting mums in containers, it's important to choose the right size and type of container. The container should be large enough to allow the roots to spread out and grow, and deep enough to accommodate the size of the plant. Mums love well-draining soil and will not thrive in containers with inadequate drainage. Choose a container with drainage holes in the bottom, and consider adding a layer of gravel or rocks to the bottom to ensure proper drainage.

Preparing the Soil

Mums prefer slightly acidic soil with a pH between 6.0 and 6.5. You can prepare your soil by mixing in compost, peat moss, or other organic matter to improve drainage and soil quality. If your soil is too alkaline, you can lower the pH by adding elemental sulfur or acidifying fertilizer. Supplement your soil with a slow-release or balanced fertilizer to encourage healthy growth and flowering.

Planting and Care

To plant mums in containers, fill the container with the prepared soil mixture, leaving enough space at the top for watering. Remove the mums from their original pot and loosen any roots that have grown in a circular pattern. Place the mum in the center of the container and gently pack soil around the roots, making sure the crown of the plant is at soil level.

Water your mums deeply immediately after planting, and continue to water them regularly throughout the growing season. Mums prefer moist soil, but be careful not to overwater, as this can lead to root rot. Fertilize your mums every two to three weeks with a balanced fertilizer, and deadhead spent blooms to encourage more flowers.

In conclusion, planting mums in containers is a great way to add seasonal color to your patio or balcony. Remember to choose the right time to plant, select the proper container, prepare your soil, and provide proper care to ensure that your mums thrive. With a little attention, your container-grown mums will produce a stunning display of vibrant flowers that will brighten up your autumn days.
