Annual Broad-leaved Weeds

A wide range of annual broad-leaved weeds can emerge from the soil seedbank and compete with crops. These plants normally reproduce by means of seeds, and in some respects they are therefore the easiest weeds to deal with as their life cycle is complete in one year. The main objective should be to remove plants before they compete with the crop early in the season and later in the year before they set seed, or impair the harvesting process. The cultural and mechanical weed management methods described under the weed management section can be used to control annual broad leaved weeds.

Below is a list of common annual weeds. If you want to add any comments please use the add comment button. We will develop the information in these areas as the site develops so if we have left anything out or there is information you want, let us know.

Comments

  1. This weed can grow to l0 feet tall if left alone. It is very tender young, but makes a tough cane when 4 months. It grows very fast, has tiny whtie flowers which grow to green seeds and they turn black when ripe (similar to blueberry looks0.
    The plant main stalk turns red when older.

    I have a lot growing in my back yard. They seem such strong plants I have cut them up and placed them in flower pots to see if they would make my roses grow better.

    Ask any questions it it would help identify the plant.

    Cout I mail a leaf to someone?

  2. Thanks for the inquiry. However, it looks like you are based in the US and we are all based in the UK. I would suggest that you contact your local university extension department (try University of Tennessee) as they are more likely to know more about your particular weed.

  5. I have a blanket of small yellow clover-like weeds taking over the lawn- they appear resistant to normal weed & feed treatment. Any ideas on how to treat? Thanks

  6. I seem to have the same problem as Ken Taylor 04-07-07. Weed and feed will not eradicate it. What do you advise to try?

  7. I have, I think, a vine-like weed that has a broad leaf and very small, somewhat sticky thorns on the stem. Each leaf has five petas on it. Any thoughts?

  8. What is the height difference between grass weeds and broadleaved weeds during winter?
