From what I can tell, the biggest thing is to keep a pond for the dragonflies to lay their eggs in. Ideally something with shallow edges and a centre depth of maybe half a metre, which gets a few hours of sunlight each day. Keep it free of animals like fish and frogs which will eat the dragonfly larvae. And grow aquatic plants, like lotuses, which rise above the water's surface.
Also, I'm pretty sure they're territorial as adults, so maybe more than one pond, if you have space?
True. Midges too. But that should give the dragonflies plentiful food. They're amazingly efficient predators in both adult and juvenile forms, and they eat something like 10% of their own body weight every day.
Catching a few dragonfly nymphs and releasing them into the ponds would probably be a good idea to kick start the process.
@InvaderXan we've already got the ponds, and I'm planting lotuses this year! Looks like I'm off to a good start 😊
@bedap Definitely! 😄
