Exposure Tuberous vervainSole pieno
These plants have an annual development, therefore when it becomes cold they deteriorate, and get completely eradicated. The Tuberous vervain can't stand temperatures below zero; they should be grown in cold green houses or at least in a place where they are sheltered by the wind; when every risk of late freezings has gone by we can place them outside or remove the protections.The Tuberous vervain should be grown in a bright place, with direct sunlight.

Watering Tuberous vervainTenere asciutto
As the cold weather arrives, in autumn, usually waterings is interrupted because these plants can't bear harsh temperatures. Water rarely, about once every 1-2 weeks with 2-3 glasses of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down.

Fertilization Tuberous vervain
Annual plants have a quite vigorous development and need, during the spring, a continuous fertilization; when placing them let’s add some humus or mature manure or some slow release granular fertilizer to the ground. During the spring months we suggest mixing some fertilizer for flowering plants to the irrigating water every 20-30 days.

Treatments Tuberous vervain
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.

Soil Tuberous vervain
We advise locating these annual plants in a dissolved soil, with an elevated drainage.
