Fall is here and most of the summer plants will not survive the cool nights and moderately warm days. Many gardeners don’t renew their containers for a variety of reasons. Changing from the summer to fall winter plant selections is often perplexing because we don’t see many of our favorites. They are unsure of how long the containers will survive and plants other than the quintessential MUM are often difficult to find. So let’s reboot that thinking.
Selection of plants for this time of year uses the same rubric as the summer months. The place and how the container will be viewed, planting zone, type of light ( full sun to full shade), the design basics of thriller, fillers and spillers and the container you use.
To save time and money you can also use the same container and plants to make a summer container and then reuse it with a fill in fall plant.

Every container needs three types of plants: thrillers, fillers and spillers.
1. A thriller is a taller plant that steals the spotlight,towering above other plants in the container. In general, the height of a thriller plant shouldn’t exceed more than 1 1/2 times the pot height.
2. A filler plant clusters around the thriller, filling in the space between its stems and soil.
3. Spillers cascade over pot edges in a waterfall of flowers or foliage. In autumn containers, low growing ornamental cabbages frequently fill the role of spillers, despite their lack of trailing growth.
Spillers typically belong near pot edges, thrillers fill the center, and fillers land between the two. If your container will be viewed from one side only, place the thriller toward the back of the pot.
