Pressed flowers going brown
Hello, I having been pressing flowers and leaves etc for a number of years. However last years cuttings when I went to retrieve them had on the whole all gone brown. Now as far as I can tell I didn't do anything different last year to what I would normally do. Please note that they had actually gone brown in the press as opposed to going brown in storage. Any advice so that I don't repeat what I obviously did wrong this time. Thanks for reading, Emma.
