While established plants can withstand drought, they’ll do better with regular watering, specifically container-grown plants. Make sure that they have adequate drainage, whether in pots or garden beds, so that the roots don’t get soaked in the soil. For best results, combine them with other plants with similar requirements for water.


In the garden in the garden, using a continuously-release fertilizer and enriching the soil with organic matter before the moment of planting is likely to suffice. In other cases, you should fertilize your container-grown plants regularly with the help of water-soluble liquid fertilizer.

One of the least hassle-free flowering plants that you can cultivate, Verbena has some pests or diseases. When problems do arise, it is due mainly to a lack of sunlight or poorly-drained soil. Here are some signs of stress to look out for and possible solutions.

Plants that are leggy and have little blooms are usually the result of excessive shade. Transfer them to a place in your garden where they receive six or more hours of sunshine. Verbenas can recover when transplanted, and so do not be afraid to move your plants to a more suitable area.

Mildew with a powdery appearance is by far the most prevalent issue. Provide your plants with enough space to allow for air circulation, and to avoid watering high up. Do not water in the evening so that the leaves don’t get wet overnight. See: How to Get Rid of Powdery Mildew.

The yellowing of leaves, the poor flowering and root Rot are all indications of poor drainage. There are many ways to save your plants by moving them to areas with better drainage or raised beds. If you have plants that are grown in containers, make sure you have drainage holes.


Spider mites are among the pests that can pose an issue. If you see netting that resembles spider webs on your plants and your leaves are discolored, consider spraying the leaves with a powerful stream of water or an insecticidal detergent. Avoid using chemical insecticides as they can cause harm to pollinators. See: How to Control Spider Mites.
