It’s a question that has crossed the mind of many an orchid lover – can you propagate an orchid by cutting off its stem and replanting it? The answer is yes, you can, but there are some things you need to know in order to get successful propagation results. In this post, we’ll discuss how and why orchids grow new stems, when the best time to cut them off is, where to plant them, and which types of orchids are the easiest to propagate this way.
Will an Orchid Grow a New Stem?
It’s a question that has crossed the mind of many an orchid lover – can you propagate an orchid by cutting off its stem and replanting it? The answer is yes, you can, but there are some things you need to know in order to get successful propagation results. In this post, we’ll discuss how and why orchids grow new stems, when the best time to cut them off is, where to plant them, and which types of orchids are the easiest to propagate this way.
How and Why Orchids Grow New Stems
Orchids have a type of growth called monopodial growth. This means that they grow from a single central stem, with leaves coming out of the sides of the stem and roots growing from the bottom. When an orchid’s stem gets too long, it becomes top-heavy and starts to flop over. To prevent this from happening, the orchid will produce new stems (called “keiki” in Hawaiian) that grow out from the sides of the main stem.
The best time to cut off these new stems is when they are about 6 inches long and have at least 3 leaves. Cut them just below a leaf node (the place where a leaf is attached to the stem) with a sharp knife or pair of scissors. Make sure to sterilize your cutting tool beforehand with rubbing alcohol to prevent the spread of disease.
Where to Plant Your Orchid Stem Cuttings
You can plant your orchid stem cuttings in either potting mix made specifically for orchids, or a mixture of sphagnum moss and perlite. If you’re using potting mix, make sure to water it well before planting so that it’s nice and moist but not soggy. If you’re using sphagnum moss and perlite, soak the moss in water for about an hour before use.
Once your cutting is planted, water it well and place it in a bright spot out of direct sunlight. You can cover it with a clear plastic container or bag to help keep the humidity high while it’s rooting. Check on your cutting every few days to make sure that the potting mix or sphagnum moss is still moist.
Which Orchids are the Easiest to Propagate?
Some types of orchids are easier to propagate than others. The easiest ones to grow from stem cuttings are Dendrobium, Oncidium, Phalaenopsis, and Vanda. These all have relatively soft stems that root easily. You may have success with other types of orchids as well, but these four are the most likely to produce good results.
With a little patience and care, you can easily propagate your own new plants from stem cuttings. Soon you’ll have more orchids than you know what to do with!
