Outdoor Potting Soil – Making A Container Growing Medium

Planting flowers and vegetables in large outdoor containers
can be an excellent way to maximize both space and yield. Though the process of
filling these pots with high quality potting mixes is relatively simple, the
cost can add up quickly. This is especially troublesome for those on a tight
budget. By becoming more familiar with the contents of outdoor container soil,
even beginner gardeners can better understand what is required to mix their own
container growing medium.

What Makes a Good Potting Mix for Outdoor Containers?

With the rise in popularity of container gardening, many growers find themselves interested in gaining more
knowledge regarding outdoor potting soil. These soils are essential for the success
of container gardens. Specific components of the soil assist with drainage,
water retention, and nutrient uptake.

Unlike the soil in the garden, it is essential that potting mix for outdoor containers
exhibits exceptional drainage qualities. This drainage is key, as it allows the
moisture within the container to move downward beyond the root zone of the
plant. Standing water within the plant’s root zone can lead to a multitude of
issues, such as root rot.

Potting mix for outdoor containers sold commercially most often contains a mixture of
vermiculite, peat, and/or coir fibers to regulate moisture levels and improve
drainage. Furthermore, these mixes do not contain soil. This allows the mix to
remain comparatively lightweight and airy, even when saturated with water.
Maintaining these consistent moisture levels will be essential to container
plantings throughout the growing season.

Creating Your Own Outdoor Container Soil

While it is possible to mix your own potting mix using
garden soil, it is best to first do thorough research. Adding garden soil to a
potting mix can be beneficial in adding additional bulk and nutrients to the
mixture. However, it will be imperative that the soil is healthy, disease free,
and free of any harmful insects or pests. In some cases, adding garden soil can
do more harm than good, so making soilless mixes is preferable.

By mastering the creation of their own potting mixes, many
gardeners are able to fill pots and containers with high quality container growing medium at a fraction of the cost to buying commercially bagged
potting soils.

Through the combination of components, these outdoor potting
soils can provide plants with ample nutrients to produce healthy and vibrant
flowering plants that thrive all season long.
