So, don't put them in a damp airing cabin, don't put them into the basement which has no heating, just in somewhere where the air can circulate nicely. So, that is how you would dry roses. I'm then going to show you how to dry hydrangea. To dry hydrangea, you need to pick them at the latest part of the year, so in October and November are ideal. That's when they're firm to the touch. I like to do it in the following way I find that you have the best results. You want it to dry very slowly. The slower is actually dries, the smoother the little petals will be once dry. So, I just take some foam that I have soaked in water and I've added a very shallow reservoir of water. I cut the stem at an angle and place in the foam and I ignore it. That's what all you need to do because it will absorb the water and then dry very slowly and in a few weeks time, the will the most perfect dried hydrangea. But hurry the process and they'll all go very wrinkly. And if you do it early in the year, they'll just go limp and die before it's dried. So, there you are. That's how to dry roses and hydrangeas
