I've been raising worms for years, best fertilizer money can buy. If you take about 2 pounds of the casting,putem in a bag made of cheese cloth, so what you have is large tea bag for worm tea. Get a 5 gal. bucket filled with rain water, drop the tea bag in,add a cup of unsulfered molasses and an air supply like the air pump in a fish tank.Leter go for 24hours and it'll start to look like root beer with the foam on the top.Strain and put into spray bottles, now you have the best liquid fertilizer that money can buy. Spray it on the foliage, it wont burn the plants, stand back and watchem go. Use it up fast as it will only keep a couple of days. And that worm tea is worth about 25 bucks a gallon.
