I need to know a good ground bait for tench and how to present it.

Try particles, hempseed,casters and sweetcorn,spread over a wide pattern.Keep them searching.
Float fish over it,lift method or laying on, with sweetcorn and redworm, or caster and redworm.
Oh yes,and it's not cool,it's fishing!

Look at VDE Superlake and VDE Expo. Use as indicated in the links. They've been going for years.

Also (find groundbaits) There Lake from Sensas and Magic. Depends whether you like liquorice allsorts or chocolate? Well, that's what they smell like to me.

if i squeeze sweetcorn and bread crumbs together with a few maggots would that be a good groundbait.

Too many maggots might break the balls up mate, unless they are dead first, a small handfull will be ok though.

Adding corn to groundbait is fine!

thanks

i might buy some powder and pellet ground bsits what do i use with these to make a bait ball

You can even mush the corn in a liquidiser or food processor first, even better!

My advice is to start with plain brown breadcrumbs in a large bait bowl. Mix water slowly until the crumb will just hold together then add some combination of trout pellets, corn, casters, chopped worms maggots or whatever, then if need be sprinkle a little more water if the balls aren't holding together well enough.

If you want to use just micro pellets as a groundbait, fill a bait box with pellets, add some water, shake and then tip off the excess water, after a few minutes the pellets will stick together enough so they can be rolled into a ball or fed through an open end feeder!

Do not think that you need to spend a fortune, another good additive is liquid mollasses which you can get from farm shops for about £4 a gallon this can be mixed in with plain brown crumb, although you might need to dilute it with water first as it is really thick.
