Select clean, healthy vegetative branch tips. Use non-flowering lower growth from pruned veg plants to pre- serve flowering tops. The thin neglected branch tips thrive in the rich nutrient solu- tion and triple in size or more. Trim into 3-inch pieces and remove leaves, leaving 1/2” of leaf stem above the node. Cut ends will be trimmed once more after sanitizing to remove bleached cut tissue. Leave one inch or more below lowest node to be trimmed so that lowest node will be located above where the media surface meets the air. This node is often the most aggressive as it is near the sugar medium and the oxygen to metabolize the sugar. Using a Washing Jar Put the pieces into the washing jar. Run some tap water into the jar and shake gently to wash off any loose material. Add a drop of simple detergent and stir to dissolve oils and begin killing mold and bacte- ria. Drain the soapy water and add the sanitizer from the culture tubes and swirl every 10 minutes. Some bleach will get on your hands, cleaning them at the same time. The objective is to clean the plants and the vessel before going to the clean hood. Trimming and Planting Dip tools in sanitizer and spill some into the plate to create a small puddle to trim cutting in. Take one cutting out of the jar with forceps and prepare to trim it again. Hold forceps as far back as you can and try to work with your hands as low as possible without reaching over the plate. You will often pass tools to your other hand across the front of the plate. Shake off residual sanitizer drops. Keep tools at least 3 or 4 inches inside of hood. Gloves are good if you have them. With the node cutting in the center of the plate, pass the forceps to your other hand and take the scalpel in your working hand, holding as far back on the tool as you can. Trim away the bleached ends of the leaf stems, or petioles, about 1/4”. Do not dam- age the bud inside the node, the growing point that will develop into your new plant, unless it will fall beneath or just above the media level, in which case remove it as it will be deformed by the direct contact with the hormone. Point the upper end of the node to the right side of the plate, put the scalpel back in the sanitizer, and pass the forceps back to your working hand. Open 24 www.GardenandGreenhouse.net April 2018
