How to Defend Your Garden from Pests, 1824

George Shaw, Zoological Lectures (1809), NYPL

"With respect to caterpillars, snails, and slugs, they can only be gathered by hand, and the way to do this effectually is to begin as soon as they appear, employing women or children to look them over daily early in the morning. Poultry, and especially ducks and sea-gulls, are sometimes of use in keeping these and other insects under; a hen and chickens will devour caterpillars and aphides greedily, but are apt to scratch the soil afterwards, if not timely removed; turkey fowls are better." 

John Claudius Loudon, An Encyclopaedia of Gardening

For pest control, try keeping a flock of women and children in your garden this year.

How to Grow an All-Purpose Herb, 1586

"To make an hearb to growe which shall have many savours and tastes. And to doo this: firste take one seede of the Lettice, one seede of Endive, one of Smallage, one of the Bassill, one of the Leeke, & of the parslie, al these put togither in a hole in such sort, that one seede may touch an other: but this remember that you plant these together in the dung of an Horsse or an Oxe without any earthe at all with them. And then after of these seedes shall growe up one proper hearbe, which will have so many savours and tastes, as there were seedes sowne together." 

A Briefe and Pleasaunt Treatise, Intituled: Naturall and Artificiall Conclusions (1586)

With the power of manure, you can grow one herb to rule them all.

How to Garden with Lobsters, 1777

"Dear Past, Bugs are eating my squash plants. How can I get rid of them? Sincerely, A Gardener"

"Procure the hollow claws of Lobsters, Crabs, &c. and hanging them in different parts of the garden, the insects creep into them, and are easily taken; but the claws must be often searched." 

The Complete Vermin-Killer (1777)

The problem with this remedy is that you'll have to eat a lot of lobsters. Organic gardening is full of hardships.
