Cranberries require up to one inch of water per week during the growing season.
If rainfall is inadequate, water is applied through the sprinkler system. Weeds may appear on a cranberry bog during the summer. Workers hand pull weeds or wipe them with a manual or mechanical herbicide applicator. Growers utilize one or two bee hives per acre of bog during early June through mid-July. Most growers use IPM techniques as an ecological approach to pest control.
