The thistle plant is recognizable by its characteristically spiny leaves and flowers. It is a large plant family that includes members such as the artichoke and milk thistle. Birds love thistle seeds. To attract finches and other seed eating birds to your garden, a small thistle patch is hard to beat. Planting thistles has its rewards, but this plant is considered a weed and tends to grow like one. A small patch of thistles today can become a large invasive problem in the near future.
Clear a patch of ground by removing all grasses and weeds. Turn the soil over to loosen it and rake the area smooth.
Scatter the thistle seeds liberally onto the prepared area; the best time to plant thistle seeds is in the cool wet days of spring and fall.
Rake 1 to 2 inches of dirt over the area to keep birds from eating the seeds.
Water the area for five to seven minutes or until the ground is wet to a depth of 3 inches. Test the depth of the moisture level in the ground by pressing your index finger into the soil.
