12 Best Thriller Plants for Fall Containers – Expert Autumn Picks

What if I told you that creating magazine-worthy fall containers is possible in just one weekend using these 12 proven thriller plants that professional landscapers refuse to share? While everyone else settles for boring mums and half-dead summer leftovers, you’ll discover the exact tall, dramatic plants that thrive in cool weather and create the stunning vertical focal points your autumn containers desperately need.

The secret to making fall containers beautiful is to select the appropriate stand out plants, which are tall, dramatic and will catch the eye and introduce the theme of your fall plants. Most of the gardeners continue to use the same chrysanthemums each year rather than the clever container designers who realize that with the correct stand out plant take an ordinary pot and turn it into an incredible autumn masterpiece that lasts long beyond the initial frost.

The Essentials of the Thriller Plant

It is best to understand why the outstanding plants are so significant when designing fall containers before you select certain plants. They provide your work with height, drama and interest in your eye, drawing it upwards. The star plant in the typical thrill-filler-spiller formula tends to occupy 30-40 percent of the graphic weight of the container, so it is the most crucial selection that you will do.

Fall stars have a worse time than summer plants: they must endure low temperatures, few days and unpredictable weather and appear good. Fall stars are the ones that are cold tolerant, have seasonal color and are built to withstand harvest time and further.

The Secret of Timing: When to Plant and Reap the Greatest Benefits

Fall standouts begin with the opportune time. When your first anticipated frost is 8-10 weeks away, plant your autumn containers so that roots have time to develop, and fall colors can be richly developed. Fall container garden planting is best done from September into mid-October, at least 6 weeks before the first frost in most regions, according to landscape professionals.

To keep the colour late in the summer on up to the frost, plant in sequence. Begin with the highlights that are at their best in late summer, and then change to more genuine fall ones later in the season. This retains your containers bright in 12-16 weeks as opposed to the traditional 6-8 week display.

Don’t use garden soil, and rather use a high-quality potting mix that may pile and retain diseases. It may be advisable to add slow-release fertilizer at the time of planting because the few days spent at fall increase the drawbacks of liquid feeding. Plant the containers in the area that they will receive optimal lighting on the selected type of plant and be easy to maintain during the season.
