Thistles are an invasive plant common in home gardens. These weeds spread through their root systems. They thrive in home gardens--areas characterized by sunny locations and moist soil. Thistles choke out garden plants, taking up valuable space and nutrients.
Mini rototillers are a smaller version of the full-size tillers. They are less expensive and lighter than full-size tillers. Mini rototillers are suited for tilling and weeding garden areas less than 300 square feet. Mini rototillers are a chemical-free, effective approach to removing thistles.
Cut off bloomed thistle flower heads to contain the seeds and prevent them from spreading. Use a clean pair of garden shears to cut the flower heads off below the blossom. Place the flower heads in a trash bag.
Dig into the soil, using the tines of the mini rototiller, to dig to a depth of 10 inches. Work until the soil loosens, proceeding in a straight line down each row. At the end of each row, turn and proceed to the opposite end.
Pull the thistles from the soil by hand once they are loosened from the soil.
Rake the thistles together. Place the thistle remains in a trash bag.
