Having gone through a similar process, which is still work in progress, I would suggest checking if anyone you know wants the plants you don't rather than just dumping them. I couldn't believe how much some of the stuff we were treating as weeds costs at garden centres!
If you make friends with your new 'green fingered' neighbours they might return the favour by sharing plants of theirs that you do like. Might also be a good opportunity to see what they have done in their gardens to give you some ideas.
