Exercise 3 solution

Example answer (yours will differ), for a bed 1.2 m x 2.4 m:
North end (so nothing is shaded): a wigwam of canes with 6 runner or climbing French beans, sown indoors in late April and planted out after the last frost in late May. Pick often from July.
Middle: 1 courgette, sown indoors in mid April, hardened off and planted out after the last frost, with space around it. Water at the base and harvest small.
South end: a short row of salad leaves and radishes, sown thinly outdoors from April and resown every 2 to 3 weeks until August, with radishes sown between the salad rows.
Keep the bed watered and mulched in summer. In autumn clear the plants, leave the bean roots in the soil, and mulch. Record the plan in the notebook for next year's rotation.
