Q.Anthurium
Have had my red Anthurium for 11/2 years. It has bloomed most of the time since, after I repotted it shortly after receiving it. It has now developed 8 additional stems in addition to the original stem Are these all separate plants in addition to the original one? They’re not overcrowding the pot, as I made a mistake when I first transplanted it by going to a pot much bigger than the original pot. I currently have a bloom on each of the stems. Should I leave well enough alone, or can I plant new stems outdoors?
Examine the plant and look for offshoots that emerge from the ground near the main stem. The shoots grow from the roots of the main plant. In one year, up to 15 can appear from a healthy anthurium.
Using sharp garden clippers, cut the roots about 4 to 5 inches deep to remove the offshoots from the mother plant. These aerial roots are necessary for successful propagation.
Replant the divided shoots in 4- to 6-inch pots that are filled with rich, organic potting soil. Keep the soil moist and place the pots in a humid location with partial sun.
