Hi Jolan
Really enjoyed these today- thanks for all your efforts.
My suggestions are the following.
1. Just prune leader in garden plot and bloom becomes something that has to be abandoned as a failure (6,5) BUSTED FLUSH
(j)UST (Just without its first letter or pruned) IN BED (Garden Plot) + FLUSH (Bloom)
2. Boxes of bracelets? (5) CUFFS
A double definition
3. Fast Teutonic dance – that is what all women do, in Rome? (4,3,5) COSI FAN TUTTE
Anagram of fast teutonic (anagram indicator dance)- translation from Italian (or Rome) ‘Thus do they all’
4. Capital cognac! Single or double? (5) CLONE
C (capital or first letter of Cognac) + Lone (single)
5. Sermonize without a church and work up to a promotion, especially within the church (10) PREFERMENT
Pre(ach)= sermonize without a ch + ferment (work up).
