There was a heavy frost last night and the ground is still hard.
These plants are particularly susceptible to frost.
In a normal winter, the frost penetrates deeply enough to kill off insect eggs in the soil.
Gardeners need to be prepared for several severe frosts in the next month or two.
However, no attempt was made to constrain vertical frost heave or simulate overburden pressures because the intention was to simulate near-surface environments.
Moreover, as frosts may have a negative impact on seed viability, we suggest that artificial sowing should take place in spring.
In the upper hills where risk of frost is high, natural pastures dominate the landscape.
