The pest doesn’t need spraying. It needs a predator. The predator doesn’t need buying. It needs a flower.<\/span><\/span><\/p>\n Plant the right flower and the predator shows up on its own, finds the pest, and does the work for free. The chain assembles itself.<\/span><\/span><\/p>\n Five chains that work:<\/span><\/span><\/p>\n – Aphids \u2192 ladybug larvae \u2192 plant yarrow. The larvae do the killing \u2014 hundreds of aphids each. The yarrow keeps the adults around to lay eggs near the colony.<\/span><\/span><\/p>\n – Tomato hornworms \u2192 braconid wasps \u2192 let your dill bolt. The wasp lays eggs inside the hornworm. The flowers are the weapon, not the dill leaves.<\/span><\/span><\/p>\n – Slugs \u2192 ground beetles \u2192 let cilantro flower. The beetles hunt at night while you sleep. The flowers give them daytime shelter.<\/span><\/span><\/p>\n – Cabbage worms \u2192 paper wasps \u2192 plant fennel. The wasps catch caterpillars, chew them into paste, and feed them to their own larvae. One nest near your brassicas catches dozens a day.<\/span><\/span><\/p>\n – Whiteflies \u2192 lacewing larvae \u2192 plant cosmos. The larvae have sickle-shaped jaws that drain whiteflies in seconds. The cosmos keeps adult lacewings fed and laying eggs nearby.<\/span><\/span><\/p>\n One flower per pest. The predator does the rest.<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":" The pest doesn’t need spraying. It needs a predator. The predator doesn’t need buying.
