Resanding and Weeds Circular No. 36 indicated that "resanding smothers many small ; This statement does not reflect current thinking on the subject, in fact quite the opposite. Sanding eventually stimulates cran- berry vine growth, and as vines thicken they tend to shade the soil surface enough to reduce the num- bers of annual weed seeds which germinate. But the first effect is that of covering surface weed seeds and insuring their moisture supply. Whenever cranberry vines are buried by the sanding operation and sunlight reaches the soil sur- face, conditions are made excellent for annual weed seedlings. In gen- eral, the year following a resanding shows an increased number of species and individuals of annual weeds. These include warty panic grass (Panicum verrucosum Muhl.), corn grass (Panicum dichotomi- florum Michx.), barnyard grass (Echinochloa crusgalli (L) Beauv.), fireweed (Erechtites hieracifolia (L) Raf.) and pitchforks (Bidens spp.) The effect of resanding on several perennial weeds is as benefi- cial to the weeds as it is to the cranberry vines. Poison ivy, which may well be regarded as the number one woody weed of Massachusetts cranberry bogs, is stimulated vigor- ously by resanding, and its pros- trate stems sent out on the soil surface the previous season are effectively anchored and stimulated to produce large numbers of adven- titious roots in the newly applied sand. Not only is the ivy growth stimulated to greater growth by the sand, but it is more difficult and disruptive to pull it out once the new roots are formed. Similar effects follow sanding of the several species of brambles, blackberries and dewberries (Rubus spp.) and in this case the rooted ends of looping stems and branches become firmly anchored, hampering and making pulling a very disagreeable and discouraging job.
