but I'm still not sure where and how I will grow them.
Maybe it works if you put up something with horizontal wiring or a fence to support the sunflowers?
I know this 10cm wide fence material is sturdy and rather cheap (used in concrete constructions) :

Dogs often get mental issues bc people don’t give the right upbringing.After reading this, the browser suggested I read this article nextCreepy internet but a good enough read:

Last week the police took away 70 dogs and pups out of someone’s basement in the Netherlands. Many pups where to young to be parted from their mother and the whole place was gross and stinky (urine).
And people often don’t realise dogs can be as dangerous as wolfs.
One week earlier a catastrophic event with huskies was on our news (from Belgium). A mother was feeding the huskies with her young son. The huskies attacked the child and the mother had a hard time to free him. The child died in hospital. And the dogs got killed, bc they can never be trusted anymore.
You’re not asking me, but I have a hen who got mental problems after her brothers left and she was a lonely pullet.Have you seen Mow's type of behavior in other birds who lost their siblings?
Janice was harassed by het aunties after her brothers left. She slept on a roost in the extension, with the other hens before her brothers left. The mother abandoned her a couple of weeks earlier and didn’t protect her. Janice started to sleep in the nest-box again, and later alone on a roost in the small coop.
She still prefers her own ‘bedroom’. Which is rather strange behaviour for a chicken.
Janice's coop. At this time the nestboxes where occupied by 2 broodies. Ini mini visited them ( being curious or wanting to steal the chick feed).
