Step 1: Recut the Stems the Right Way

Make a fresh diagonal cut
Trim about 1/2 to 1 inch off each stem at a 45-degree angle.
A diagonal stem cut gives the stem more surface area to drink, which is exactly what a droopy bouquet needs.
Use sharp tools, not dull scissors
This part matters a lot.
Dull blades crush the stem instead of opening it, and crushed stems are terrible at rehydrating.
Cut under water if you can
If you want to be extra careful, trim the stems under water or move them into water immediately.
That can help reduce air embolism in stems, which is just a fancy way of saying tiny air bubbles can block water flow.
Strip what sits below the waterline
Remove any leaves that would fall below the water.
This one small step cuts down on rot and keeps your clean vase routine from turning into dirty swamp water by dinner, and in the next section I’ll show you why hydrangeas need hydration from the top and the stem.
