A nearby gardener will not watch over your growing belladonna plant. Farmers must pick nightshade with gloves equipped, or they will be hit for 20 poison damage instead of harvesting the nightshade. Certain decorative gloves, such as Samid's gloves, Santa gloves, Mime gloves, and Hati paws or gloves from Fist of Guthix, such as cadantine gloves, do not work safely. Some other items that go in the hand slot like the Regen Bracelet do not work, but other hand slot items like the farmer's cuffs do work.
