Verbena Plant Care & Growing Guide

1. Light Requirement

The verbena plant loves to be in the sun. It requires at least eight hours of full sun every day, so keep it in a sunny spot. It can live in indirect light or partial shade, but the leaves won’t be as strong, and the flowers will be lackluster and dull. It doesn’t do well under artificial lighting. If it’s an indoor plant, keep it the brightest room you have, preferable where the sun’s rays can hit it. 

2. Water

Overwatering this plant is a death sentence, so be careful. In fact, water-based diseases are the most significant problems you’ll try to avoid when you own this plant. When there is no heat, an inch of water is enough for the week. But when the heat and sun grow more robust, you’ll have to test the soil every day to see if it’s drying out. It is a drought-resistant plant, so you don’t have to water it so much. But the less water it receives, the less its flowers will bloom. If it is hot, rewater it and turn the soil moist. Do not water the plants from above; only water them under their foliage.

3. Climate and temperature

Verbena plants love the heat. It is a desert plant and has no problem standing tall during the hottest days of the year. These plants do best in hardiness zones 7, 8, and 9. If a verbena is growing from propagation, it is better designed to handle the heat. 

4. Soil

This plant can grow in most types of soil, even if the nutrition is poor. But the ground needs to drain well, or it can die if it is overwatered too often or if there is a long rainy season. For better plant structure and bloom, it is recommended that you add fertilizer pellets to the soil.

5. Speed of Growth

Depending on the type of verbena it is, they will have a moderate to fast growth rate. Some of the verbenas grow so fast they extend past their containers and barriers in no time. This is why gardeners must trim the plant so often. 

6. Height and Width of the plant

The height and width of the verbena plants vary wildly, but on average, they can grow from one to three feet tall and have a width of six to 12 inches. Some varieties can grow taller than five feet. Their size depends mostly on the amount of sun they receive and how well they are trimmed. 

7. Trimming

Proper trimming is essential to this plant because if it doesn’t have to waste nutrients and energy on large leaves and dead matter, then it can dedicate that energy to its flowers. After the first bloom, slowly trim back the entire plant to make way to a second bloom. This plant requires regular maintenance. 

8. How to propagate a verbena plant?

Propagating a verbena plant is quite easy. Choose a long stem and cut off a piece that is around 4 inches, ending the cutting directly below a node so that the node can become an extra leaf. Many people dip the cutting in root hormone to encourage rooting, but you don’t have to. Place the cuttings in water and leave it next to a window that receives a lot of sun. In a few days, you should start to see roots. Once the roots appear, bury the cutting an inch or so into a pot with soil. Keep the soil moist and under direct sunlight. 

Is the Verbena Plant Poisonous?

Most of the varieties of verbena plants are non-toxic and won’t poison humans or animals if they eat the berries or flowers. The only species of verbena that is toxic to animals is the purple top verbena.

Common Verbena Plant Diseases

Powdery mildew is when a white fungus grows over the leaves and stems of a plant. This mildew is common to see. If it doesn’t become bigger, then it is only an aesthetic problem. But if it does keep growing over the whole plant, it could stunt a plant’s growth and cause leaves to dry up. To remove it, first cut off all pieces of the plant that are infected. Throw them away. Second, apply neem oil spray or a mixture of baking soda and water to the entire plant. 

Gray Mold is a sneaky killer, and if you don’t catch it in time, this fungus can kill your plants. The verbena plant can contract gray mold is there is too much moisture around, and a gray mold spore lands in warm wet soil. First, it infects the leaves, and then gradually moves to stems, flowers, and roots. Gray streaks will appear first over the leaves. It then turns the surface of the plant black and causes it to die. To remove the gray mold, you first have to remove all infected parts and throw them away. Then, spray the whole of your remaining plant with a potent fungicide.
