Some weed suppression can be achieved by simply spreading a mulch layer 2" to 4" thick. If a mulch layer is in place and some weeds do emerge, they are more easily removed. Landscape Fabric is a gray woven synthetic material that when used by itself or in combination with organic mulches can provide a satisfactory weed barrier for several years. For those gardens that require more drastic measures, we stock a complete line of professional pre/& postemergent herbicides.

Our selection of preemergent herbicides like oryzalin (Surflan & Weed Stopper), metolachlor (Pennant), oxadiazon (Ronstar & Pre Pair) and napropamide (Pre Pair) allow you the flexibility to select a specific herbicide that best fits the problem weed species in your garden. When applied before weed growth begins, these preemergent herbicides will prevent weed seeds from ever germinating. Postemergent herbicides like sethoxydim (Grass Getter), fluazifop (Fusilade II & Ornamec) and our organic fatty acid (Scythe) can safely be used in your rose garden for controlling most actively growing weed grasses without damaging your roses.

Many hard to kill broadleaf weeds such as oxalis are extremely difficult to control by hand. We do stock effective broadleaf herbicides, however they must be used with extreme caution. Roses are extraordinarily sensitive to broadleaf weed killers and even the slightest amount of drift can cause stunted, twisted, cupped, curled, chlorotic foliage and even death to your plants.

Damage from the popular non-selective herbicide glyphosate (Roundup) is commonly mistaken for disease or insect damage on roses. Be aware that damage from Roundup can occur the following season if fall applications are made near your roses and accidentally drifted on the susceptible green stems.

For your information, we've provided a handy conversion table cross referencing the comon name with their trade names.
