Carrots

To grow them to perfection carrots require a deep, rich,sandy soil, which has been thoroughly trenched and manured the
previous autumn. For the main crop the seed should be sown in March,
either broadcast or in rows 18 in. apart. A calm day must be chosen
for sowing, as the seed is very light and liable to be blown about. It
has also a tendency to hang together, to obviate which it is generally
rubbed into some light soil or sand previously to being scattered.
Thin out to a distance of from 4 to 7 in., according to the kind
grown. For early use the French Horn may be sown on a hotbed in
January and February. Keep the surface of the ground well open with
the hoe.
