Dry Hop Questions

[vindee]

I'm doing another Amber Ale and want to dry hop for more aroma.
I have my own hops growing and should be ready to pick in 2 or 3 weeks.
Is there anything that needs to be done with them to eliminate the possibility of spoiling the beer from wild yeasts or something like that?

Also, I usually don't do a secondary when fermenting. But I have read that you add hops for dry hopping in the secondary. Is this necessary?
Thanks

Hops are fairly antimicrobial. No special steps before adding to beer (which already has some alcohol in it too prevent contamination)

I add dry hops to primary all the time. No negative effects.

It is possible but not typical. The one time I used homegrown hops for dryhopping is the only time I've ever gotten an infection and a funky sour IIPA (now I save homegrown for the boil only).

Can you achieve similar results by maybe adding more hops in your final addition of the boil?
