I know that May Day in this part of the world is not as it is in the other hemisphere, and going into the darker colder months is not as appealing or encourages all that singing and dancing. However, it should not put you off the planting and gardening, as there is still plenty to do this time of the year.
Please see below a guide to what you can saw this month. It is certainly not a full list, and micro climates need to be considered, but there is enough choice to ensure we are all kept busy.
Enjoy
