The best weedkiller for bindweed is a systemic weedkiller containing glyphosate, like Roundup Ultra. This is applied to the leaves and absorbed into the plant, killing roots, stems and leaves. The most effective time to use weedkiller on bindweed is in summer when the plants start flowering.

Both boiling water (organic) and non-selective herbicides (chemical) can be used to get rid of bindweed. Both of these options can kill any plant where applied. These methods are ideal for areas where bindweed is growing but there are no other plants you wish to save.
