Hollyhocks and zinnia,s

Good afternoon everyone,
This is my first post, (apart from introducing myself) so hope i have posted on the right thread:o.I have grown some hollyhocks and zinnia,s from seed, and they are now large enough to be potted on into 3" pots, do i still have to keep them inside once potted on?, or can i leave them outside in a plastic greenhouse.

Thank,s in advance.

 

They will be fine outside! My hollyhocks tend to self seed and come up all on their own wherever their seed has blown! I never know what colour they are going to be until they start to bloom. It's a nice surprise.

 

Stick em outside ! Get ready to plant and get ready for seeing my favorite flower next year. Good luck
