Aphids

, Cutworms

Cutworms

A seedling lying beside its own stump in the morning, cut clean through at soil level.

Attract Hoverflies

Hoverflies

Syrphidae

The adults only drink nectar. It is the larvae that eat the aphids.

, Lacewings

Lacewings

Chrysopidae

Golden-eyed adults that mostly drink; larvae that hunt like small alligators.

, Ladybugs

Ladybugs

Coccinellidae

The one predator here where the adults hunt as hard as the larvae do.

, Parasitic wasps

Parasitic wasps

Braconidae, Ichneumonidae and relatives

Pinhead-sized, stingless, and lethal to aphids and caterpillars from the inside.

, Predatory mites

Predatory mites

Phytoseiidae

Too small to see without a hand lens, and the main thing holding spider mites down.

, Minute pirate bugs

Minute pirate bugs

Anthocoridae

Two to three millimetres, and both stages hunt — thrips and spider mites, thirty a day.

, Ground beetles

Ground beetles

Carabidae

Night-active ground hunters, taking slugs, cutworms and leatherjackets at soil level.

Growing from seed

Direct-sow Yellow Wax Bean outdoors about 1 weeks after your last frost, keeping seeds in warm soil (around 20–25 °C). Seeds usually come up in around 8 days. Grow in full sun, spaced about 10 cm apart. Expect to harvest in roughly 55 days.

Yellow Wax Bean seed rarely stays viable beyond 3 years — track what's still worth sowing.

  Growing Beans: Bush or Pole, Snap or Dry

  Beans are the crop most likely to be called easy and most likely to be grown wrong. Almost every decision — where they go, what you feed them, when you pick — follows from two questions you answer before you sow: how tall does this one get, and are you eating the pod or the seed?
