Each month of the growing season has my recommended sowing dates for each vegetable, to increase the likelihood of successful harvests. Every date is based on decades of fine-tuning from observations and learning over many years.

• Use these dates to help you enjoy a regular supply of fresh produce through all four seasons.

As well as sowing dates, I have added a brief vegetable growing summary for every month, to help you keep on track. There are also tips for successful growing using no dig, as well as useful information on multisowing – the reasons why I recommend it and a table giving my recommendations for multisowing of different vegetables. The calendar also includes beautiful and informative photos from my garden at Homeacres.

The calendar sowing dates are for a Zone 8b climate in southern UK. You can use this calendar in different climates, with a little adjustment to the dates. If your climate is cooler, sow later by 1-4 weeks in spring, then sow a week or two earlier in summer and autumn, from the solstice onwards.

My recommended dates are not always the same as you will read on the packet of seeds! For some reason, they pay little attention to flowering dates and, for example, I do not recommend to sow spinach, as in true spinach not leaf beet, from late April through to late July. That way you avoid its flowering season. By sowing either very early in the year or in August, you are far more likely to enjoy a long season of harvest. For a monthly summary of which seeds are best to sow when, in a temperate climate, see my sowing timeline. There is also a version for the southern hemisphere.

We also offer weekly newsletters with a weekly reminder of what best to sow, transplant, harvest and other jobs. It’s £5 monthly from February to October. It includes contributions from new grower Anna, who helped with this calendar, and from other no dig gardeners who are enjoying success around the world. See also our International page.

Climate plus natural growth cycles
My sowing dates are based on season, climate, and the natural growth cycle of each vegetable. For example, your peas will succeed much better when you sow in spring rather than summer. That’s because peas grow most healthily and abundantly during months when the days are getting longer. Sow at the best time of year for each different vegetable.

Dates are based secondarily on moon phases.  Within the best seasonal times, the moon cycles sometimes give even better times!

Solar and lunar
I combine two aspects of moon movements for calculating top sowing dates:
One is the phases of root-flower-leaf-fruit, based on whether the moon is passing through an astrological sign with earth-air-water-fire qualities.
The other is waxing and waning. Where possible, sow on a waxing moon for faster emergence and stronger growth, especially just before full moon.
Sun and moon give a framework of action, rather than a rigid rulebook. Many dates have sowing possibilities – there are few dates when all of the good aspects are present.
