Depends on the state of the grass rather than the date. If its dry you can cut it but be careful when turning the mower as the ground may still be very soft. We cut some of ours this afternooon.

Hi i have cut three lawns so far this year the first was on 30th of jan as steragram says if it is fine and dry then there should be no problem but cut it on a high cut and check the weather forecast.good luck.
