Attracting Pollinators and Beneficial Insects

The most productive gardens are busy with insects, and that's a feature, not a problem. Bees pollinate the flowers that become your squash, cucumbers, and melons, while a whole army of less-famous insects quietly hunts the pests that would otherwise wreck your crops. Attracting pollinators and beneficial insects — gardening for these allies rather than against all bugs indiscriminately — is one of the quiet keys to a healthy garden.

Pollinators and beneficial insects: two kinds of allies

It helps to know who you're inviting and why:

• Pollinators (bees above all, plus butterflies, moths, and hoverflies) move pollen between flowers. Many of your crops can't set fruit without them: the whole squash, cucumber, and melon family depends on bees, and poor pollination is the reason for a lot of misshapen or missing fruit.
• Beneficial predators and parasites: ladybeetles, lacewings, hoverfly larvae, parasitic wasps, and predatory bugs eat or parasitize aphids, mites, caterpillars, and other pests. A garden full of them keeps pest outbreaks from ever building, which is why this overlaps so much with companion planting that works.

Plant flowers — lots of them, all season

The single most effective thing you can do is grow flowers among and around your vegetables, and keep something blooming from spring to fall so there's always food. A few principles:

• Diversity and succession. A range of flower shapes and colors feeds a range of insects, and a continuous bloom keeps them fed all season rather than for one short window.
• Favor small, open, clustered flowers for the beneficials. The tiny predators and parasitic wasps feed on nectar from small accessible blooms: think the flat flower heads of dill and other herbs, and let some cilantro, basil, and brassicas flower.
• Old garden standbys earn their place. Marigolds, nasturtiums, zinnias, sunflowers, alyssum, and cosmos are all magnets for pollinators and beneficials, which is the real reason they show up in so many companion-planting schemes.
• Let some herbs and crops bolt. A bolting lettuce, a flowering carrot, an herb gone to bloom — these are insectary plants in disguise. Leaving a few to flower feeds your allies for free.

Stop killing your own helpers

Here's the part that matters most and costs nothing: go easy on insecticides. Broad-spectrum sprays don't distinguish friend from foe — they kill the bees pollinating your squash and the ladybeetles eating your aphids right along with the pests, and the predators are often slower to recover, so spraying can leave you worse off as pests rebound unchecked. So spray only when truly necessary, choose the most targeted product, and apply it in the evening when bees aren't foraging. Provide a little water (a shallow dish with stones to land on) and leave some undisturbed corners for nesting, and your garden builds its own pest-control and pollination crew — the foundation of growing more with less intervention.
