Tesla Coil Grounding?

Hi!
I made a tesla coil like this guy!
https://www.instructables.com/id/Tesla-Coils-for-Dummies/

But I didn't ground the secondary coil of the tesla coil. It seems to work ok without it, but I'd like to see it preform better. Would it help if I grounded it? 

Thanks!

Could you elaborate more on how to ground this? Would just using the grounding plug on an outlet work or would I have to go outside and drive a stake into the earth to ground it?
Given Tesla coil's propensity for injecting HF signals into the supply, I'd prefer my own connection to the house's ground stake if it has one, or an independent ground.
