Broadleaf Weeds

A general term applied to unwanted plants that have branched veins in the leaves (i.e. they don’t run parallel from base to the tip like in grasses). Commonly found in lawns, garden beds and between pavers.  Plants often regarded as broadleaf weeds include: dock, thistles, dandelion, dasies, clover, buttercups, plantain, onehunga weed, and speedwell.

Prevention

Weeds flourish if space is left for them. In garden beds don’t leave bare spaces, either plant plants you want or heavily mulch (which will help suppress weeds). In lawns weeds tend to take over when patches appear or if the lawn is mown too closely. Fertilising lawns regularly and making sure they stay healthy also lessons the chances that weeds become a problem.

Treatment

In lawns selective herbicides can be used to kill broadleaf weeds while leaving the grass unharmed. Spray with Turfix, or to feed at the same time use Weed n Feed, which can be attached to a hose and easily applied. Just be careful not to get spray drift onto broadleaf plants and shrubs that you want to keep. For harder to kill weeds such as Oxalis or Onehunga Weed Hydrocotyl Control or Lawnpro Prickle control may be more effective.

Other Options

For a natural option spot spray weeds with Organic Weedfree. This oil based spray causes plants to burn in the sunlight. Some perennial weeds may need multiple applications to kill them off as this product only kills the foliage.

Alternatively ——– weedkiller is a can be spot sprayed and doesn’t remain active in the soil. It will kill grasses or other plants if the spray drifts. Zero Gel can be applied to the back leaves of weeds to kill them.
