Ok, since we are talking about weeds, I will tell what I did last year. I usually plant around 35 tomato plants towards the back of my garden, under the shade of some pine trees. It takes a little longer for their fruit to ripen in the shade, but it is well worth the wait. The sun down here in Georgia can get quite hot during July and it will bleach the western side on any tomato of mine that has full exposer. Anyway, crabgrass also grows very well in this enriched and slightly shaded soil.
So sometime last July I was down on my hands and knees ripping it out of the ground. I would toss it in the center of the rows and then come along later and fork it all up. Well, on this particular day, an afternoon storm chased me out of the garden after I'd pulled a good bit of this ornery weed grass. As luck would have it, I started in on another project at about this time and did not bother to resume the weed pulling for at least four or five days. When I went back out, I was astonished. All the Crabgrass I had previously pulled had nit back down and had to be pulled again. Needless to say, I didn't think that this was very fair. /forums/images/graemlins/crazy.gif
So, if you pull them, you had better toss them. Forget the rain.
