Let's water abundantly, moistening the soil deeply with 2-3 glasses of water , but let's act only when the substratum is dry, leaving it dry even for 1-2 weeks before watering it. As the cold weather arrives, in autumn, we can interrupt watering, and let the plants perish.
Light Vervain
The Vervain should be preferably located in a place where it can have at least a few hours a day of direct solar light. The Vervain can't stand cold weather, therefore in general it should be grown in a sheltered place; during the Spring months, when the minimum temperatures are above zero, it can be moved outside.These plants shouldn't be grown in the garden during the cold period; in autumn the plants usually perish, and should be eradicated from the ground.

Pests Vervain

Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
