Thanks for the nice comments everyone. Yes my plants are always properly trimmed and well groomed. It provides much better health to the plant, IMO.
BigCarnivore- Yes I do allow all my pygmy dews to grow crowded together...but harvesting the gemmae is a sinch. When the carpet of plants has ripened its gemmae brood I simply turn the pot upside down and rub my hand gently across the plants and BILLIONS of gemmae fall onto a large sheet of white paper. Any gemmae left clinging are removed with the help of a pair of forceps.
