I've got a very small 8ft by 8ft garden that has tomato and bean plants.
My problem is that for some reason each year thousands of little grass
type of weeds pop up. They are difficult to get to do to sheer number and
closeness to the other veggie plants.

My favorite when I'm doing stand up weeding is this sort of hoe:

a scuffle hoe. For close-in work, I like something that looks sort of
like a hunting knife:

(price is way out of line, though!)


Is there a small weeding tool that might help? Or do you have any
recommendations. It seems I'll weed one day and they have returned the
next.

Mulch. A couple three inches of dried grass, straw (not hay) or even multiple
layers of newspaper will do it. The secret to not having to weed is canopy
closure, and when the canopy is open when your plants are young, the weeds
will sprout. Give 'em some artificial shade with mulch.

Classic book on mulch gardening: Ruth Stout's How to Have A Green Thumb Without
an Aching Back. Most libraries should have a copy in the system.

P.S. I saw this little tool that looked like a serrated Sickle(sp) that
had a fork at the end that is for small weeding. would that amount to
anything?

Might. Anything that fits your hands and the way you use your muscles and
gives you enough control that you're not going to do in your string beans
while trying to nab a mile a minute vine will do nicely. In fact, it's good
to have several weeding tools and switch off so all muscles get a bit of
work, and nothing gets overused.
