(Cucumis sativus) 20 seeds per packet (unless otherwise noted). Cucumbers flourish best in rich, loamy soil. When the weather has become warm, plant in hills 4 to 5 feet apart each way, putting 10 to 12 seeds in a hill. As the plants appear above the surface, they should be diligently watched and protected against insect enemies. This may be accomplished by sprinkling hydrated lime, ashes, tobacco dust or other insecticides on the hills. Finally, thin the young plants to 4 in each hill. For a succession, continue plating at intervals. Fruits should not be left on the vines to ripen, as this diminishes productiveness. For late pickles, sow in late June.
