    I read on your post that the root of the sunflower inhibits growth of other plants. Well not here in NE Colorado, USA I have the happiest bind weed that just about strangles out all my sunflowers if I do not get down and pull it all out as the plants grow. Would you suggest spaying the area a few months before I sow seed with a pre-emergent? Thanks.

    Ummmmm well I am not really surprised as bindweed spreads by an underground root system and the ‘vine’ effect would strangle the best of plants, but certainly sunflowers would not be a match for this predator!! If I had the problem of bindweed I would dig out a trench and sift through the earth to remove as much of the underground white root parts, the I would cover the area with a thick black plastic, making sure NO light could seep underneath. Leave this in place for a month or so and then leave the area fallow – manured and mulched for a winter and summer then see if the bindweed re-appears, if it does start the procedure again. If not plant to your hearts content, but an invasive weed will always have the upper hand over annuals. Good Luck and Happy New Year:)
