HELP! Herbarium question…!!
As part of my Master Gardener program, I have to get samples of about 30 plants. I've started on the evergreens, it takes a while to press the plants adequately (I tried the miorowave method bit it burst into flames.. oops). So far, Ive done everything except some needled plants. How the HECK do I take a sample and preserve something like Douglas Fir,Balsam Fir or Norway Spruce? They're kind of hard to press, since they stick out in all directions...? They don't really press even CLOSE to flat, like a hemlock or juniper. I'm deprived.. I never did flower pressing in camp as a child :( Any advice? Thanks!
