Exercise 1 solution

Example answer (yours will differ):
Suppose the plan assumes a last frost around late April and your area's average last frost is in mid May (3 weeks later). Then:
- Planting out beans and courgettes (May in the plan) moves to late May or early June, about 3 weeks later.
- Sowing them indoors moves 3 weeks later too (to April), so seedlings are not stuck in pots for long.
- Potatoes: plant when the soil is workable and shoots will not emerge into hard frost, or protect shoots with fleece or earthing up (check).
- Hardy salad and radishes can still go out in April, with fleece if a frost is forecast.

If your last frost is earlier, such as early April, the same jobs move earlier by a few weeks. The principle: count back or forward from the last-frost date, and keep the order of jobs the same.
