Scotts Lawn Builder™ +Weedkill Slow Release Lawn Fertiliser:
Feed your lawn and tackle selected broadleaf weeds in one measured application. This granular lawn treatment combines selective weed control with slow-release nutrition to promote greener, thicker growth on the lawn types listed below.
Its time-release feeding helps sustain growth over three months, while the herbicide combination targets young, actively growing broadleaf weeds. Apply evenly at the recommended rate for consistent results.
Important: Not suitable for buffalo grass, including Sir Walter, Palmetto and Sapphire, or for carpet grass, lippia, dichondra or Santa Ana couch. Do not use on bent greens.
Benefits:
- Feeds and controls selected broadleaf weeds in one application.
- Slow-release feeding supports sustained lawn growth for up to three months.
- Iron and sulphur support deeper green colour and stronger growth.
- A thicker lawn helps reduce opportunities for new weeds to establish.
- Measured granular application through a suitable spreader helps achieve even coverage.
For Control Of:
Bindii (Onehunga Weed), capeweed, catsear (flatweed), chickweed, mouse-eared chickweed, clover, dandelion, fat hen, creeping oxalis, mallow, pearlwort, plantain (lambs tongue), staggerweed, fumitory, cobblers peg, hydrocotyl (pennyweed) and wireweed.
Suitable For:
Lawns containing common couch, bent (excluding bent greens), kikuyu, perennial ryegrass and/or Chewings fescue only.
How it Works:
Selective herbicides act on susceptible broadleaf weeds, while the slow-release fertiliser supplies nutrition over time. Even distribution is important: untreated patches may remain weedy, while concentrated deposits can burn the lawn.

Treat weeds while they are young and actively growing. Avoid application to weeds stressed by drought, frost or excessive moisture. Choose calm conditions and a day when temperatures are not expected to exceed 30°C.
Do not apply if rain or irrigation is expected within 24 hours. Do not reapply within 10 weeks. For new lawns, wait at least four weeks after the first mowing. Do not lay new turf or sow lawn-patching products within one month after treatment.
How to Use
- Measure the lawn area and calculate the total quantity at 16 g per m². Weigh this amount before filling the spreader.
- Apply to moist foliage. If necessary, lightly wet the lawn before treatment.
- Set your spreader for this product and distribute the weighed quantity evenly. Make at least three passes from different angles, using about one-third of the total quantity in each pass.
- Leave the product undisturbed for 24 hours, then water in thoroughly. Avoid rain, irrigation and heavy foot traffic during the first 24 hours.
- Do not mow within 48 hours of application. Sweep granules from paving and other hard surfaces immediately.
Spreader settings apply to the named models. Check the pack and your spreader model before use; settings are a guide and do not replace weighing the required amount.

Important Safety Notes
- Always read the product packaging and follow its directions. Do not exceed 16 g per m²; uneven or excessive application can burn the lawn.
- Do not use on buffalo, carpet grass, lippia, dichondra, Santa Ana couch or bent greens. Do not apply on or around food plants or animal feed crops.
- Keep granules away from desirable plants, shrubs, flower beds and vegetable gardens. Grapevines and tomatoes are particularly sensitive. Avoid drift.
- Keep containers and granules out of drains, sewers, streams, ponds and other waterways. The product is harmful to aquatic organisms and very toxic to some plants.
- Do not feed clippings from treated areas to poultry or other animals.
- Wet granules can cause iron stains. Sweep them off paths, coping, paving, driveways and shoes immediately; prevent contact with wet hard surfaces.
- Store securely in the original closed container, in a cool, dry place away from direct sunlight and out of reach of children and pets. Ingestion can be harmful, including to dogs.
- Avoid eye contact and dust exposure. Follow the protective-equipment requirements on your pack; the published product label specifies elbow-length PVC gloves, goggles and a disposable dust mask. Wash hands after use and clean gloves and goggles after each day’s use.
Frequently Asked Questions
Can I use this on buffalo lawn?
No. It is not suitable for any buffalo variety, including Sir Walter, Palmetto and Sapphire.
How much should I apply?
Use 16 g per m². Multiply the lawn area by 16 to obtain the required grams, then weigh it before applying.
Should I water straight after spreading?
No. Apply to moist foliage and leave undisturbed for 24 hours before watering in thoroughly. Rain, irrigation or heavy foot traffic during that period can reduce weed control.
When can I mow?
Do not mow within 48 hours of application.
Can I use it on a new lawn?
Wait at least four weeks after the new lawn’s first mowing. Do not lay new grass or use lawn-patching products within one month after application.
How soon can I repeat the treatment?
Allow at least 10 weeks between applications and follow the pack directions.
Does feeding for three months mean three months of weed prevention?
No. The feeding period describes nutrient release. The weed treatment targets susceptible weeds present at application; it is not a three-month weed-prevention guarantee.
Can treated lawn clippings be fed to animals?
No. Do not feed grass clippings from treated areas to poultry or other animals.
