Planting and Care

Choosing the Right Location

Verbenas thrive in full sun, requiring at least six hours of direct sunlight per day. They also prefer well-draining soil, as their roots can easily rot in overly moist conditions.

Soil Preparation

Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility. Verbenas prefer a slightly alkaline soil pH between 6.5 and 7.5.

Planting Techniques

For annual verbenas, plant them after the last frost date in your area, spacing them 8 to 12 inches apart. Perennial verbenas can be planted in early spring or fall, with a spacing of 18 to 24 inches.

Watering and Fertilizing

Verbenas have moderate water needs, requiring regular watering to keep the soil consistently moist but not waterlogged. Apply a balanced, water-soluble fertilizer every four to six weeks during the growing season for optimal bloom production.

Pruning and Deadheading

Regular deadheading, or removing spent flowers, will encourage verbenas to continue blooming prolifically. Pinching back the plants occasionally will also help promote a fuller, bushier growth habit.

Overwintering

If your verbena blooms start to fade or become washed out, it could be a sign of too much direct sunlight or heat stress. Providing afternoon shade or increasing water during hot spells can help revive the plants.

Leggy Growth
