Dandelion roots can be harvested during any frost-free period
of the year and eaten raw, steamed, or even dried, roasted and ground into a coffee substitute.
Accordingly, the frost-free period fluctuates from 125 to 175 days.
A number of negative correlations are related to the decrease in temperature in the direction to the north: MTWM, sums of active temperatures (SAT), duration of the frost-free period (FFP), and CCI, etc.
Altogether, 10 climatic parameters were analysed; among them no correlations were found of the distribution of the Tilia taxa with the average temperature in July (MTWM), the duration of the frost-free period (FFP), and the mean annual sunshine duration (MASD).
Because the Carolina wren's winter range is conditioned by the average minimum January temperature and the mean length of the frost-free period
, the expansion of its winter range is often cited as an indicator of climate change.

PREPARE the ground for new trees and shrubs in a frost-free period
The longer-range forecast from the London Weather Centre is also for a mild, frost-free period
with the odd shower.
Much more important is pruning at the right ti Small branches up to one inch in diameter, or 5pc the total crown, whichever is less, and dead wood any size can be removed at any time of the year with problems although the pruning of box hedges must confined to frost-free periods
because of the risk frost damage to the freshly-cut surfaces.
