If it's a busy wedding weekend will start greening up on Mon/Tues. Flowers go into the greened arrs from the Weds for Sat. HT bouquets I do up to 2 days in advance and keep in the cold room, dependant on what's in them. Tied table arrs to go in vases on the Weds for Sat and change the water Sat morning as they are loaded up. Shower bouquets, wired work, carmen roses, any funny bespoke bouquets all done the day before.
Don't you find everyone gets married on the same weekends? It's not uncommon for us to have 4/5 over a weekend, up to 7 once

, that was fun haha. Tends to always be the first weekend of the month that's busiest for us for some reason.
