How to Grow Viola Throughout the Season
Growth Habit: Grown throughout the northern hemisphere, Violas thrive in the wild and domesticated into home gardens making them adaptable. Most varieties are grown either as an annual or biennial, while a few are perennial. Self-contained, violas do not spread by a root system, or become invasive yet will frequently disperse seed to far reaches of the garden, allowing violas to pop up in placed not expected.
Staking: No staking is required.
Watering: Violas prefer well-drained soil, and can develop root rot or leaves can mold if grown in standing water or in overly tight conditions. If growing in containers, hold back on overwatering and use as an understory to taller plants to give them a little shade during the summer heat.
Fertilizing: Like most flowers, viola enjoys fertilized soil in order to produce strong roots, leaves, and flowers, yet don’t overdo or the stems will become long and leggy. Some fertilizer may be given mid-season, during and after flowering.
Mulching: No mulch is required, yet violas will tolerate mulch to keep roots shady and moist.
Trimming & Pruning: Violas required no pruning except to deadhead spent blossoms on a regular basis, and trim back if plants become too leggy mid-season, allowing plants to regrow into stockier form.
