Gardeners often ask why they have so many weeds.
Weed seeds can blow in, wash in with surface water, or be introduced with the application of soils and organic matter, like manure. Birds and other wildlife also distribute weed seeds. However, the majority of weeds come from seed unsuspectingly planted by the Gardener. In other words, weeds we allow to go to seed. For example, a common pigweed plant, with its long reddish taproot, produces one hundred and seventeen thousand seeds per plant.
