For my Victorian friends and those not up here in NSW these are “catheads” these things make regular bindi’s look like fairy floss! They will puncture a bike tyre in a second and they spread like... well like weeds!
Proper name is Caltrop Tribulus terrestris and ‘caltrop’ actually means “spiked weapon” for my landscaping mates
🌳Quick Tip!🌳— Did you know that the best time to trim your trees is between late fall and early spring? In fall and winter, trees enter a dormant stage, halting their growth. This inactivity along with dropping temperatures creates an ideal setting for pruning. If you prune after new growth has started, you can limit the tree or plants bloom potential for the year.
