Creeping Jenny, also known as field bindweed and creeping Charlie, is a member of the mint family. Of value medicinally a long time ago, when it shows up in the garden it becomes a pest. Creeping Jenny has a deep, extensive root system that is challenging to kill. The best time to work on ridding the yard of creeping Jenny weeds is while it is actively growing and in bloom.
Mix 1 1/4 cup of borax in 1/2 cup of hot water for every 1,000 square feet of weeds. Borax is available in the laundry soap area of your supermarket.
Pour the borax and water solution into 2 1/2 gallons of water in a tank or other type of garden sprayer.
Spray the creeping Jenny until it is dripping with the solution. Do not allow traffic or water on the area for 48 hours.
Solarise bare soil infestations of creeping Jenny. Water the soil to a depth of 10 inches and cover it with black plastic. Use rocks around the perimeter of the plastic to hold it tight against the soil. Allow the plastic to remain during the hottest part of the summer, and remove it in the fall.
Apply a post-emergent herbicide containing Trimec, according to package directions, on the lawn. This product will not harm turfgrass.
Apply the Trimec herbicide to flower gardens carefully. Cover desirable plants with a tarp if the wind may cause the product to drift. Spray the herbicide directly on the creeping Jenny until it is wet but not dripping. Repeat the application in six weeks or when the product's label specifies.
Spray a broad-spectrum herbicide with glyphosate on bare soil. Follow the label instructions carefully. Again, be mindful of desirable ornamentals in the area, and cover them if there is a chance of drift.
