November is the time to reflect on the previous season. Review what went well and want went wrong. Consider what you grew too much of and too little. What turned out to be the best time to sow particular cultivators. Plan next year.
Weather permitting it is also time to tidy the plot.
Particularly gather any leaves that my have fallen in your garden or allotment. Store them in a separate container than your compost heap. In a years time they will have rotted down into leaf mould. You can also cut down their stems and leaves to about a foot from the ground. One plant that can be sown this month is long pod broad beans.
