When to use


  • The unique sources of nitrogen and iron are highly soluble and quickly absorbed to provide a rapid greening response
  • It goes to work immediately and is effective whether it is absorbed through leaves/blades of grasses or roots
  • The 2L Easy Sprayer fast hose-on application bottle is perfect for small to medium-sized lawns, covering up to 130 m(roughly half a tennis court)
  • With a high concentrate of active ingredients, it effectively controls clover, bindii (jo-jo, Onehunga) and broadleaf weeds including capeweed, chickweed, creeping oxalis (not in Tasmania), cudweed, dandelion, dock, fleabane, lamb's tongue (plantain), wireweed
  • Lawn Builder Weed, Feed & Green-up 3in1 has a low 0.7% phosphorus, which means it can be safely used anywhere in Australia without posing any risk to ground or surface water



  • Lawn Builder Weed, Feed & Green-up 3in1 can be safely used on lawns containing buffalo varieties (including Sir Walter, Palmetto, Saphhire, etc), Santa Ana, common couch, bent (not bent greens), kikuyu, perennial ryegrass and/or Chewings fescue. It is also safe to use on lawn substitutes

How much do I need?

To determine the size of your lawn, multiply the length x width in metres 1 large stride = approximately 1 metre


How do I apply it?

  1. Shake the bottle well before attaching to the hose - ensure the thumb switch is in the OFF position first
  2. Tighten the hose connector on the handle prior to connecting the hose; turn the hose tap on
  3. Extend the hose to the farthest part of the lawn to be treated before you start and work back towards the tap or path, so you are not walking over herbicide-treated areas and potentially spreading herbicides where they are not wanted
  4. Slide the thumb switch to the ON position to feed, weed and green your lawn or slide to the WATER position to just water your garden
  5. Walk slowly using a sweeping action to evenly distribute the spray over the measured lawn area
  6. For accurate dispensing check the handy view strip on the side of the bottle
  7. When finished, switch to OFF position and turn hose tap off

Note: For new varieties of Buffalo Lawn we advise you test a small patch before applying to the entire lawn

When to Use

  • Lawn Builder Weed, Feed & Green-up 3in1 may be applied at any time of the year when weeds are actively growing, although results may be slower during winter
  • Do not use any other lawn fertiliser 7 days before or after application
  • Allow at least two days after mowing before applying this product
  • We recommend you do not mow for 7 days after application to allow the best absorption for optimal results, although the bottle states do not mow for at least two days after application
  • Do not apply on windy days or if rain is expected within 24 hours
  • Avoid using during weather extremes - frosts or heatwaves



CAUTION: This product may cause staining of hard surfaces if wet. Avoid contact with hard surfaces and if contact does occur, hose off immediately
