When plant specimens are pressed it is important that the plants do not get mold or mildew growing on them. When plants are placed in the press they should be positioned so that leaves are not all bunched on top of each other. Spreading the leaves out on the newspaper so that they are not touching each other will help prevent mold and mildew. Several layers of newspaper or blotter paper need to be placed between each plant specimen. Plants that are especially juicy or wet should have the newspapers changed every few days. Under normal conditions, specimens dry completely in a week or so. However, if there has been a lot of rain and the humidity is high, the newspapers should be changed every two to three days until the specimens are dry. Remember to keep all the collection data with the plant when you change the paper.
