Perennial noxious weeds can have a large, deep root. They can be very difficult to completely kill out.
In the spring energy that has been stored in the root is used for the plant to sprout. During the growing season the leaves/stems feed the root which stores the "energy" to sprout next year.
Some of thees perennial noxious weeds can have huge roots. In Tx, we have what is called bull nettle. Its very hard to kill out. I decided to dig one up and was amazed. The root was 4 inches in diameter and 32 inches long. With roots like that your perennial noxious weeds can take several years to kill out.
If the noxious weed is cut back when the sprout is just a few inches tall, the leaves have not had time to replace the energy the root expended to sprout. By cutting frequently, the root is forced to expend more energy to sprout over and over. If cut frequently enough, the energy stored in the root is used up and the root dies.
The same effect can be achieved by spraying when the noxious weed is just a few inches tall. This kills the food supply to the root and also kills at least part of the root. If the weed sprouts again, spray again.
Either way, these types of weeds are a real pain to eradicate.
Good luck, just be patient and stick with it. You"ll win in the end.
