We have massive growth of bindweed in our garden. Is there a safe way to get rid of it?

Bind weed is a tough one and requires a multi-pronged approach.
1. Pulling by hand the root system can be several feet long and at a break point a new plant will start, so pull with care; never chop with a shovel or hoe, again creates new plants.
2. Herbicide application timing is an important consideration with this choice, as other plants can be adversely effected.

Time: Apply at bud growth stage or at summer fallow in early August.

Remarks: Use 2,4-D to help reduce bindweed stand 60 to 80% and prevent seedling establishment. It is important to apply 2,4-D every year; skipping an application gives bindweed a chance to recover.

Important: Field bindweed grows and spreads from seed and from an extensive rootstock. Plants are prolific seed producers, with an average plant producing over 500 seeds. Within a month, the seed coat has matured and become impervious to water. With such an extensive root system of lateral and vertical roots, a plant can spread radially more than 10 feet in a growing season.
