Several species of annual violas are ideal for pots on the balcony in both early spring and fall. These plants love cool temperatures, so they need to be replaced with warm plants as soon as the cool weather of spring gives way to early summer. They are low-growing plants and look best when either planted in a wide, low dish or used as a filler or topping plant in mixed containers with larger specimens.

Pansies love cool weather in April

Pansies and their smaller relative, the viola, love cool weather and will fade if it gets too warm. Fertilize them lightly during the growing season – too much fertilizer will make them leggy, but if they don’t get a little nutrition, they won’t bloom.

You can plant balcony boxes, along with pansies and violas, or with other cool-weather annual spring bloomers.

In a mixed container on the balcony, you can replace them with other plants later in the summer when they have faded.
