Step by step

  1. Plant onion sets for greensMar

    Push sets in 5 cm apart in close rows; they are grown for green stalks, not bulbs.

  2. Start the zucchiniMay

    Sow zucchini in a pot in early May; one plant fills the whole bed.

  3. Pull the spring onionsMay–Jun

    Harvest whole young plants as soon as the stalks are pencil-thick.

  4. Clear the onion rowsJun

    Pull the last onions and rake the bed level for the zucchini.

  5. Plant the zucchiniJun

    Plant the zucchini in the centre of the bed and water generously.

  6. Harvest zucchiniJul–Oct

    Cut fruits at about 20 cm; frequent picking keeps the plant setting new ones.

  7. Clear the bedOct

    Remove the plant after the first frost blackens the leaves.

Why this combination works

Onion sets planted in March give green bunching onions by May or June with almost no work. Clearing them frees the entire bed exactly when the heat-loving zucchini needs the room to sprawl, and the allium residue is traditionally credited with deterring soil pests before the sensitive young zucchini roots out.

Tips

Pick sets the size of a hazelnut; bigger ones bolt. Water the zucchini at the base, wet leaves invite mildew. Feed the zucchini with compost tea every two weeks. In a cold June, cover the young plant with fleece overnight.
