The Kalendarium Hortense was published by John Evelyn in 1683. It contains instructions for what a gardener should do throughout the year. The excerpt below is the list of what is to be done in the "Orchard and Olitory1 Garden" for the month of April.
Sow sweet Marjoram, Hyssop, Basil, Thyme, Winter Savory, Scurvey-grass2, and all fine and tender Seeds that require the Hot-bed.
Sow also Lettice, Purslian, Caully-flower, Raddish, &c.
Plant Artichoke-slips, &c.
Set French Beans, &c. And sow Turneps to have them early.
You may yet slip Lavender, Thyme, Peneroyal, Sage, Rosemary, &c.
Towards the middle of this Month begin to plant forth your Melons and Cucumbers, and so to the later end; your Ridges well prepared.
Gather up Worms and Snails, after evening showers; continue this after all Summer rains.
Open now your Bee-hives, for now they hatch; look carefully to them, and prepare your Hives, &c.
