    Cloning Tips

    Cloning, or asexual propagation, is the act of generating a genetic copy of a plant by replanting a part of the original plant. The technique is used successfully by many commercial greenhouses throughout the world to successfully grow large quantities of standardized  plants. Wild plants such as spider plants and strawberries, and even trees like poplars use this method to increase their size. Cloning is a great way to maintain a perpetual garden and cut down on the cost of buying seeds every year. Also, because each clone is a genetic copy to the original plant there will be little to no variability between clones. To take a clone you must:

    1) Find a healthy above-ground stem on the plant, preferably a lower branch. 2) Look at the stem you selected, make sure there are at least 3 total nodes on the stem. One node at the very top, one at the bottom and one in the middle. A node is where the petiole connects to the main stem. 3) Remove the leaves and petioles completely from only the bottom node, roots will emerge only from nodes so it is important to get this right. 4) Using a sharp blade angled downward at a 45 degree angle, cut as close to bottom node as you can get without actually cutting the node off. The bottom stem of the plant should be angled like the tip on a hypodermic needle. 5) If using a cloning gel or solution apply that generously to the entire bottom node.

    GROW GREEN MI TIPS FOR CLONING SUCCESS

    • You should take cuttings from stems with a diameter of ⅛” to ¼”, these will root the most easily.
    • Feel the node where the roots are going to grow. If it feels hard/woody try to select a stem with softer vegetative tissue
    • Use a clean razor blade or scalpel. Sharper is better, but be careful!
    • If you have taken a cutting which has very large leaves or a smaller stem, cut off part of the leaves to prevent losing too much water to transpiration.
    • Oxygenate your water!

    Growing Wheat Grass

    What is wheatgrass?

    The name wheatgrass refers to the cotyledons (young leaves) of a germinated wheat plant. The wheat seed is sowed and before any flower growth can occur the cotyledons are harvested. It is the same species of wheat that is grown commercially, however it is only grown for a fraction of the time. Red wheat is typically the most common.

     

    Materials needed to grow wheatgrass: Products Reccomended by GrowGreenMi!

    1. Wheat seed - many sources online, coming soon to GrowGreenMi)
    2. Mason Jar with lid - any large retail supermarket
    3. Plastic Tray (10”x20”) - http://growgreenmi.com/garden-supplies/cloning/tray-dome/mondi-propagation-tray-1020-no-holes
    4. Medium (Soil/Coco works best) - http://growgreenmi.com/growing-media/coco/roots-organics-coco-palms-1-5-cubic-feet

    How do you grow wheatgrass?

    There are only a few steps before you are growing wheatgrass successfully:

    1. Germination – sprouting the seed
    2. Transferring – placing the sprouted seed in your medium [Some people prefer to germinate seeds directly in their medium, omit this step if desired]
    3. Vegetative Growth – allowing the wheatgrass grow
    4. Harvesting – collecting the lush wheatgrass

     


     

    Germination - 2 different ways to germinate your seeds

    Place your seed in the mason jar, and then pour fresh water into the jar until the level of water is just above the level of seeds.                                                         Sprouting Seed

    Place the lid on top of the jar and allow the seeds to absorb some of the water for 24 hours.

    After 24 hours, pour the old water out and replace it with fresh water.

    The lid can be used to prevent seeds from falling out while draining.

    Wait 12-24 hours, or until the roots emerging from the seeds are about ¼ inch long.

    The seeds are now ready for transferring.

    -OR-

    If you want to germinate your seeds directly in your medium, just wet the medium generously and spread the seeds evenly over the surface.

    Place a humidity dome over the top to keep the water from evaporating too quickly, and the seeds will begin to sprout in the humid air of the tray.

    Skip the transferring step below if you choose to use this method instead of germinating in jars.

     


     

    Transferring (optional)

    Fill your tray with at least 1 inch of media so the roots will be sufficiently anchored. Try to make sure it is evenly distributed in the tray. A variety of media may be used to grow wheatgrass, peat moss or coco based media absorb water and are common media.

    Dump out the sprouting seeds and try and spread them evenly over the surface of your soil with your hand. Pre-wetting the medium will help to avoid disturbing the seeds before they are stable and rooted.

     


     

    Vegetative Growth

    vegetative growth

    Wheatgrass grows best with moderate light. Ambient light in most homes is generally enough to grow wheatgrass, but placing the traynear a window or in a well lit area will yield the best results. Avoid direct sunlight as this can cause the seeds to get too hot and dry out.

    Diffused light is best, so if you are using a light make sure to place it 24-48 inches above the trays.

    Keeping the tray medium moist is also important. Misting the tray generously twice a day with a spray bottle generally is sufficient. Excessive moisture can encourage mold growth so dont water too much.

    It takes 10-20 days for wheatgrass to grow, and when you are satisfied with its size you are ready for harvesting.

     

     


     

     Harvesting

    harvesting

    There are many ways to harvest wheatgrass. A sharp pair of scissors is easy to find and works well. Holding the scissors horizontally,  cut sections of the fresh wheatgrass as close to the root as possible.

    The nutritional contents of wheatgrass are difficult to preserve once separated from the root, so it is recommended to only harvest what  you are going to use immediately.
