How to Care for the Plant

Soil
The plant is self-fertile. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade.
Temperature
Thus, in Thlaspi arvense (field pennycress), an exposure to cold temperature (2-10°C for several days) followed by a return to normal temperature (21 °C) induces stem extension growth and flowering. These effects can be obtained by application of GAs without exposure to cold temperature.
Additional
All parts of T. arvense contain varying levels of glucosinolates, which can be toxic if consumed in large quantities. The amount of this chemical varies with the stage of maturity of the plant; the highest amount is in the seeds.
