I’m totally new to gardening (as in not-got-a-clue-what-I’m-doing-but-enjoying-it!) and trying to spruce up our front garden to ease my mind during lockdown. Victorian terrace so small & fairly shaded. It is also over run with slugs & snails. Children & I have planted loads of seeds in pots & it’s lovely to see them ‘popping up’ ( clearly not a gardening term!) however in the past anything I’ve tried to grow had been destroyed by the slimy little creatures.
We have a fabulous local nursery which is doing a roaring trade at the moment & I have booked a delivery for next week. Problem is I don’t know what to ask for. Given that I’m a complete novice, what would you recommend? I’m thinking growing everything in pots (that’s what we’ve done with the seeds) as the snails/slugs are less likely to get at them? Any plants I should definitely avoid?
I don’t think I’m looking for advice on how to get rid of the slugs and snails because I’ve tried everything. I figure I just have to accept they’re there. 
Many thanks in advance.
