Propagating a house plant is your only alternative when a plant out grows it's potPropagating your own house plants is a challenge that many indoor gardeners relish. New plants can be created in several ways, including stem and leaf cuttings, air layering, and divisions. Some house plants like the piggyback and the spider plant, for example—almost beg you to make new plants by growing easy-to-root plantlets. You can get stem or leaf cuttings by pruning your own leggy or misshapen house plants, or you can find other enthusiastic indoor gardeners who are willing to share cuttings with you. Though you can't expect instant results with propagation, time and patience should reward you with many new house plants. Rooting plantlets - These ready-made tiny plants appear as outgrowths or appendages above the soil on an established plant. The plantlet that forms at the base of a piggyback leaf, develops on the bloom stalk of a spider plant, or grows on the frond of a mother fern only needs to come in contact with moist potting mix to form roots and grow into a self-sufficient house plant. The easiest method for rooting is to place the plantlet (still attached to the leaf or stalk of the parent plant in a container filled with moist potting mix. Use clothes pins or partially opened paper clips, if necessary, to keep the plantlet in contact with the soil. Keep the mix constantly moist but not soggy. When you notice new growth on the plantlet, sever the connection with the plant by removing the stem. Or you can start by detaching the plantlet and placing it directly into the prepared soil. Leaf and stem cuttings. Most cuttings will root in either potting mix or water. Prepare the cutting this way: remove lower leaves; dip the stem into rooting hormone and then insert it into the rooting medium. Keep the rooting medium moist but not soggy. When the cutting produces new growth, you can plant it. For the rooting medium, you can use vermiculite, coarse sand, a mixture of half perlite/half sand, or a commercial potting mix with enough perlite added to make the mix lighter in texture. Whatever you choose, be sure it is sterilized to minimize the risk of disease organisms destroying the cutting before it can root. Air layering - This propagation method is best for tall, lanky, single-stemmed plants—such as split-leaf philodendron that are difficult to grow from cuttings. The principle behind this method is simple: you cut or scar the stem to stimulate root formation at that point. With a sharp knife or razor blade, cut or scar the plant stem just below a leaf node, cutting about halfway through the stalk. Brace the stem, if necessary, with a small piece of wood. Then place moist sphagnum around the cut stem, wrap it with clear plastic film, and tie the plastic in place. When roots begin to show through the plastic, sever the rooted portion from the parent and plant it. Dividing plants - With this propagation method, you create new plants by dividing the growing centers of large plants that grow in clumps or form multiple growing centers. Each clump or crown—called a growth center —has its own root system. Agapanthus, asparagus ferns, and African violets can be propagated in this way. All you need to do is remove the parent plant from its container, brush or wash away the potting mix around the roots, and carefully cut or pull apart the various growth centers. Then repot each of the individual plants into smaller containers. To repot your house plant, have all the needed supplies assembled. Quantities of the correct potting mix and the necessary tools should be handy. The new container should be 1/2 to 1 inch larger in diameter than the plant's present pot. |
