Heavy Duty Steel Tree Support Kit, Tree Stake Kit for Newly Planted Trees Against Bad Weather, Include 6 PCS Tree Straps for Staking, 6 PCS Tree Stakes and 2 PCS Rope of 31.2 FT for Anchoring (2)

All 7 of my shrubs still have the nursery stakes with the green ties. Should I remove them? I read removing the stakes will allow the tree/plant to grow on its own strength and not grow relying on the stake. How would I adjust the nursery stake without damaging the root ball? Would something like this be overkill or waste of money? https://a.co/d/0fNCFMc6
