第一篇：
Pothos plants are one of the most popular houseplants. They aren’t fussy about light or water or fertilization
and when it comes to how to propagate a pothos, the answer is as easy as the node on the stem. Pothos
propagation begins with the root nodes on the stem right below the leaf or branch junctures. These tiny bumps on
the stems of rooting pothos are the key to propagating pothos. When an aging plant begins to get leggy or a full
and healthy plant grows too long, simply give the plant a haircut.
To begin the process of propagation, one will snip off 4- to 6-inch lengths of healthy stem for the pothos
cuttings, making sure each cutting has four or more leaves. Then, the leaf that is closest to the cut end needs to be
removed. Once the stems are cut, they’re ready to begin rooting. Pothos propagation can be accomplished in two
ways. One might want to try both to see which one works best.
The first method of propagating pothos is to place the cut ends of the stems in water. An old glass or jelly jar
is perfect for rooting pothos. The jar of pothos cuttings needs to be put in a place that gets plenty of light, but not
direct sunlight. About a month after the roots begin to show, one can plant the cuttings in soil and treat them as
one would any other houseplant. Be careful though, the longer pothos cuttings remain in water, the harder time
they have adapting to soil. It is best to transplant rooted pothos cuttings as soon as they start roots.
The preferred method of how to propagate a pothos begins the same as the first. Take the pothos cuttings and
remove the first leaf above the cut ends. Dip the cut end in rooting hormone. Make sure the first set of root nodes
is covered. Set the cuttings in a potting mixture of half peat moss and half perlite or sand. Keep the soil moist and
keep the rooting pothos out of direct sunlight. Roots should develop after one month; and after two or three
months, the new plants will be ready.
