vegetable patch design
Another thing to consider when siting your vegetable patch is what will be next to the vegetable patch that might harbour snails and slugs.
Brick walls and concrete paths off ideal barriers to Large snails and slugs as there is nowhere for them to hide.
If you cannot avoid having your vegetable patch near cover for snails and slugs then consider creating a gravel path as a buffer zone.
Shrubs, small trees, rock gardens and long grass against fences make ideal cover for such creatures. If possible use pre existing features such as concrete paths and brick walls as borders to your vegetable patch. As well as offering little cover for large snails and slugs they also act as heat banks, which will raise the temperature of your vegetable beds. Something that is very useful in early Spring.
While it is useful to make use of pre existing features to deter these pests this should not override the key factors listed on the Siting webpage. Which are sunlight, shade and the distance from your kitchen.
Sometimes you cannot avoid placing your vegetable patch near good cover for large snails and slugs. If this is the case then consider placing a gravel or even grass pathway between you and the cover, as even this small gap will act as a some deterrence.
