Identify my vervain
Not to be mixed with lemon verbena, which has no link. Purple flowers in clusters, upright stems, square, opposite, toothed leaves.
Plant my vervain
You will plant the verbena officinale in spring or autumn. Choose a sunny and well drained location in winter (otherwise it may freeze), not too poor. Add compost during plantation, if necessary.
Water my vervain
There are two types of watering for verbena: in open soil, the first month after planting, water every two days. For potted plants, water twice a week unless the pot is outside and it has rained in the meantime!
Cut down my vervain
You can cut the dry tufts low at the end of the season, if their appearance bothers you.
Propagate my vervain
Verbena seeds itself spontaneously, so you will probably have some new ones to transplant regularly. You can also divide them in the spring, with a spade.
Mulch my vervain
Mulching verbena presents a single risk: if it is in a heavy and wet soil, the presence of soil moisture under the mulch could weaken it in the winter.
In other cases, mulch without second thoughts twice a year, to protect the soil in the winter, and to avoid watering and weeding the rest of the year, with mulch or shredded wood.
