that seeds will not sprout without heat.

If the weather is warm place one of the tumblers in a refrigerator.

Why don't we plant corn in December?

Why not plant melons in January?

The seeds of farm crops may be divided into two classes according to
the temperatures at which they will germinate or sprout readily and
can be safely planted.

Class A. Those seeds that will germinate or sprout at an average
temperature of forty-five degrees in the shade, or at about the time
the peach and plum trees blossom:

Barley Beet Parsley
Oats Carrot Parsnip
Rye Cabbage Onion
Wheat Cauliflower Pea
Red Clover Endive Radish
Crimson Clover Kale Turnip
Grasses Lettuce Spinach

These can be planted with safety in the spring as soon as the ground
can be prepared, and some of them, if planted in the fall, live
through the winter.
