Buy Weed Killer Online

4 min read

At Jonathan Green, we’ve made it easy for you to buy weed killer online for your lawn and to get advice from experts.  Weeds are everywhere, but they can be properly controlled.

Jonathan Green has been growing beautiful lawns for six generations (since 1881). Today, we are a major supplier of genetically superior cool season grass seed, fertilizers, soil enhancers, organics, and weed, insect, and disease control products to the professional lawn care markets. Our products will transform your lawn and help it thrive.

How Did the Weeds Get into My Lawn?

They have always been there. Weed seeds can remain buried and dormant in the soil for years, and the weeds will wait for the proper environment in which to grow. 

Topsoil has weed seeds in it.  Processed loam has weed seeds in it.  Mulches have weed seeds in them.  Weed seeds are blown in by the wind.  And birds are another source of seed dispersal. The seeds the birds eat pass through their digestive systems and are deposited on your lawn with a little bit of natural fertilizer!

Lawn weeds can be divided into two main groups – grassy weeds (crabgrass, goosegrass, dallisgrass, etc.) and broadleaf weeds (dandelions, clover, chickweed, etc.). Our Weed Reference Guide will help you identify the weeds in your lawn.

Weed Prevention Solutions

Jonathan Green has several very effective, weed control and lawn food products that can be used on your lawn, including:

Veri-Green Crabgrass Preventer plus Lawn Fertilizer: If you have too much crabgrass each year, apply this product in spring. It controls crabgrass before and after it germinates and contains the newest crabgrass-killing technology named Dimension® Crabgrass Control Herbicide. When applied in late summer through early fall, it also helps to control annual bluegrass (Poa annua) when it first germinates. Do not seed for 10 weeks if the regular rate was used and 16 weeks if the heavier rate was used.

Corn Gluten Weed Preventer plus Lawn Food:  Organic Weed Preventer helps prevent the growth of certain broadleaf (dandelions, clover, chickweed, etc.) and grassy weeds (crabgrass, etc.). It contains a patented, highly concentrated corn gluten that prevents many of these common weeds and rivals some synthetic products. It will green up the lawn quickly and release organic proteins into the soil to encourage root development. Apply it to the lawn in the early spring and again in later spring, summer and fall, but do not apply grass seed for 60-90 days after applying this product.

Lawn Weed Control: Lawn Weed Control contains Trimec®, a herbicide that suppresses broadleaf weeds when they are actively growing. It kills hard to control weeds such as dandelions, clover, chickweed, henbit, oxalis, wild onion, spurge, and over 200 other lawn weeds. Apply it to moist grass, and avoid mowing for 2 days before and after application. Do not water for 2 days after application. This is a straight weed control product; it does not contain any fertilizer, so there is no possibility of overfeeding and burning the grass.
