Repotting Orchids-步步高i606

Landscaping-Gardening Orchids cannot sustain themselves in the same potting mix indefinately. When you buy a new plant it may have potting mix that has broken down. This will smother the roots. Once the new orchid has finished blooming, it is time to repot it. Orchids should be repotted when they are in active growth mode, this occurs right after blooming. Orchids in active growth mode are sending out new shoots, leaves, and roots. The orchid should be repotted when the new roots are around about 2 inches long. Dendrobiums should be repotted only during new growth, whereas Phalaenopsis can usually be repotted whenever they are not in bloom. Orchids are not potted in soil. They are usually potted in bark or coconut husk chips with sphagnum moss. Orchid potting medium needs to drain well and not hold too much excess water since the orchid roots can rot if they are encased in moist soil for a long period of time. Potting mixes that contain small particles are the best for orchids with small roots and new seedlings. Mixes with large particles are better for orchids with thicker roots. To begin the repotting process, first unpot the orchid. Get your work area ready by spreading out some paper towels or old newspapers. Turn the pot upside down and rap on the outside of the pot to break the orchid free. Any roots that are sticking to the pot, use a clean knife to pry them loose. Once the orchid is out of the pot, pull the roots apart and shake off as much of the old potting mixture as you can. The orchid’s roots much be trimmed prior to repotting. The best root trimming tools are a heavy, sharp scissors, shears and a sharp knife. To prevent the spreading of disease by your cutting tools, wipe the blade with a cloth soaked with rubbing alcohol in between repotting different orchids. Remove dead roots. Dead roots are light brown and mushy to the touch. Roots that are healthy are firm and greenish white with light green tips. Now it is time to pot your orchid. If you are using a clay pot, soak the clay pot in water for 2-3 minutes. Then let the clay pot dry out. If you are using a preused pot soak the pot in a mixture of 10% bleach and water, dip it, rinse and then let it dry out. Orchids need thorough drainage, so place a thick layer of broken clay pot pieces, large coconut chips or styrofoam packing peanuts in the bottom of the planting pot. Wet the potting medium with boiling water, let it drain and cool off. When placing the orchid’s root bundle in the pot, place the older pseudobulbs against one side, leaving enough room for the new root lead to grow. Fill in with moist bark mixture around the roots, lightly packing it around the roots. The top of the bark chips should be level with the rhizome. About the Author: 相关的主题文章:
