The Gardeners Almanac

The place to find out what to do in the garden this week
My Back Garden

The Vegetable Garden in May


This month is a busy month as many varieties of plant require planting out or sowing insitu.

A layout plan can be quite useful to ensure you that you are planting in places that suit your rotation plan, particularly if you have had to change your initial plan due to perhaps a crop failure or some such mishap.

The same layout plan can be referred to in following years, again to help with crop rotation.

Note: As with most advice on gardening the advisors location will often influence the content of the advice.

To alleviate this problem I have produced this chart indicating how you can make adjustments to the timing of events as seen in this website.

I hope you find this useful! .......Tg
