If you are growing mostly summer vegetables you can treat the bindweed in the spring before tilling your garden:
- Spray the bindweed when it has runners at least 10 inches long.
- Spray with a 5% solution of Roundup Super Concentrate (3/4 cup of Roundup per one gallon water) or other 41% Glyphosate product, through a pump-up type hand sprayer
- Clean the sprayer well before using if you have used the sprayer with other herbicides such as 2,4-D Amine or injury to the garden may result
- After spraying the bindweed, wait at least one week before tilling and preparing to plant
Bindweeds with well-established root systems may reappear before the end of the garden growing season but will give you less trouble in the garden.
