As many of us have found the "weed block" fabrics, or the plastic sheets, simply do not work well. What does work somewhat is newspaper or cardboard laid on top of soil and covered with a mulch material of some kind.

There is actually a good body of evidence that supports the use of plastic mulch sheets in the veggie garden. In addition to aiding in weed suppression - and depending on how its done, it can be very effective in this regard - it also preserves soil moisture, increases soil temperatures, reduces soil compaction and can increase yields. There are also colored plastic mulches that are intended for specific types of crops to increase yields and encourage better growth.

Benefits of plastic mulch sheets in the veggie garden.

btw, if you are using soaker hoses to irrigate, there is no need to poke holes in the top of the mulch sheet. If using the hose correctly, all the water will seep slowly down into the soil profile - nothing should be puddling or pooling on top
