Picture this: it is a sweltering hot Brisbane day and you need to cool off and quickly! It has been a hot and dry summer so the sprinkler is on after quite a few weeks of no rain and your high-quality turf is suffering. You kick off your thongs and make a dash for the sprinkler, you’re nearly there until you feel that familiar sharp pain in your foot- a bindii. A bindii in your foot is incredibly painful, especially in the sensitive feet of little ones. So how do you keep bindiis from growing on your new turf? What do you do if they appear?
What Are Bindiis
A bindii is a weed of the same family as the cactus. It has a prickly seed capsule that can get stuck in your shoe or your barefoot and boy do they hurt. Bindiis are difficult weeds to get rid of because they have a long taproot that goes deep into the ground and spreads at the surface level above the ground. They flower over winter and autumn, but their seeds can germinate during spring and summer. If there’s enough moisture after rain or irrigation, spikes will arise.
Prevention is Key!
Preventing bindiis from appearing on your turf is the best way to keep them away. Bindiis thrive in hot and dry climates with full sun. To prevent them from settling in your fresh turf, you’ll want to take care of your grass. Prevention is achieved by mowing regularly, watering it regularly and feeding your high-quality turf with a well-balanced fertilizer. If you do these things, you should find that your lawn is less susceptible to bindii damage and less likely to have an infestation.
How to Remove Bindiis
If bindiis have decided to move in, there are two ways to remove them effectively. The first method is by removing it by hand. You will need a garden tool that will allow you to pull them out at the roots. This is best done when your turf is moist and before the flowers seed which is generally in October and November.
The next best way to rid your turf of these weeds is by spraying them. The best weed killer for bindiis contains bromoxynil plus MCPA, or dicamba. It is essential you select the right spray that will feed your lawn whilst targeting bindiis. If you apply the wrong spray, you could end up killing your lawn while the bindiis live to see another day.
The Natural Way
If you’d like to avoid weed spray, the most effective natural way is by pouring boiling water over the weeds and burning them. This method is problematic when the bindiis are in your lawn or nearby plants as they will also die. This method is for pavers only.
Applying vinegar and salt is another popular method to remove them naturally. This method will also kill grass and nearby plants so should only be used when applying to pavers.
When Should I Spray?
Spraying your lawn is an important part of the lawn-care process and prevention and management of unwanted weeds, but when should you spray?
It is best to spray on a warm, dry day preferably under 30 degrees. You should plan to spray when you’re not anticipating rain for 24 hours and wind is minimal. Ensure you cover your mouth and nose and wear proper protective gear like garden gloves.
The best way to protect your high-quality turf is to prevent bindiis from becoming a problem. This is achieved by keeping your lawn healthy and well-watered. If you already have a bindii problem, it’s not too late! You just need to take action now before it gets out of hand.
