Lesson 6
Adjusting your rhythm
The gardening calendar in books is a guide, not a schedule. A cold April means you sow three weeks later than the instructions suggest. A warm March means you sow two weeks earlier — but only if you have watched the soil, checked the forecast and accepted that you may still lose plants to a late frost. This is not recklessness. It is calculated risk, which is what all good growing requires.
The worst strategy is to ignore conditions and sow on the 'correct' date anyway. I have seen allotments full of courgette seeds sown in mid-April because the packet said so, every one rotted by early May because the soil was still 8°C. The growers who wait until late May, who sow into warm soil under a clear forecast, harvest four weeks earlier because their plants never stall. Speed comes from timing, not from starting early.
Keep a simple weather diary — a notebook, a note on your phone. Record the date of the last frost, the week your soil reached 10°C, the day your tomatoes went out permanently. Next year, you will know whether your garden runs early or late, and you will stop guessing. This is how you become fluent in your own plot — not by reading books, but by reading your own seasons.
Common mistakes
- Sowing 'on time' into cold soil and wondering why nothing grows
- Trusting a single warm week in March as proof that spring has arrived (it hasn't)
- Hardening off for seven days, then planting out without checking the forecast
- Assuming your garden is the same as the book's garden (it is not)
- Blaming the weather when you ignored the weather
How to start a simple weather diary
- 1.In January, note the first snowdrop, the first day above 10°C, the coldest night.
- 2.In March, record the date you see hawthorn buds swell, when soil reaches 7°C, the last air frost.
- 3.In May, note the day tomatoes go out for good, the first runner bean flowers, the arrival of aphids.
- 4.In October, record the first frost, the day you lifted dahlias, when the last courgette fruited.
- 5.Each January, compare this year's dates to last year's — you will see your garden's real rhythm emerge.
If you remember only one thing, remember this — cold nights matter more than warm days when it comes to young plants.
