The muntjac get blamed for everything here. . But I love having them in residence
good decision mikzxr, far too many chemicals used on far too many gardens.
You could upload a photo so we can see the damage Ruth. Generally speaking when a conifer has gone brown it doesn't recover.
You could look at Viburnum davidii, that's quite small
Might be a Weigela, one of the yellow leaved cultivars
I don't know the rules
It'll tick over til you move.
Test the soil before you make an offer on the house
I didn't realise it was in a container. How big is it? paeonies are potentially big plants and do much better where the roots can expand into soil. That may be holding it back from flowering.
You won't get those big multi-petaled pompom flowers from seed but I see that as an advantage, so do the bees.
