Just wanted to let you guys know about some improvements I have had in the garden after using some of moreless' ideas.
I have taken over a small vegetable/herb garden. It is mainly planted with perennial herbs with some space for annual hearbs, salad crops and the likes. When I got here the garden looked ok but every time I planted seedlings or sowed seeds the new plants were immediately devoured by snails and slugs. In an attempt to rectify this problem I have been trying to improve the soil so the plants may be healthier and not so appealing to the pests. Firstly I sprinkled rock dust all over and dug it in, then watered with a solution of molasses, fish emulsion, a pinch of sea salt and a little epsom, finishing off with a thick layer of mulch. I have been alternatively watering with diluted sea water and the molasses solution once a week and applied a little more rock dust. [I really didn't know how much of anything to put on so I have been doing a little at a time and building up slowly]. I have planted new seedlings and my sewn seeds are are all flourishing with barely a snail in sight. I don't have a refractometer with me so I haven't been able to test the brix level but I'm sure it has risen.
