How to Take and Root Stem Cuttings
Stem cuttings are the workhorse of plant propagation, working for the widest range of houseplants. Learn how to cut at the node, root in water or soil, and avoid the common mistakes.
Stem cuttings are the most versatile propagation method because almost any vining, trailing, or branching houseplant can be multiplied this way. The principle is simple: a stem segment with a node will grow new roots from that node and become a complete plant.
The single most important concept is the node — the slightly swollen point where leaves, branches, and aerial roots emerge. A cutting with a node can root; a cutting without one cannot. Master finding the node and the rest is just choosing water or soil.
Step by step
- 1Sterilize your tools
Wipe scissors or a knife with rubbing alcohol before cutting. Clean blades prevent you from spreading disease into the open wound, which is one of the top causes of cutting failure.
- 2Locate a node and cut below it
Find a healthy node and cut 1/4 inch below it at a slight angle, leaving one or two nodes and a few leaves on the cutting. A 4-6 inch tip cutting roots most reliably.
- 3Strip the lower leaves
Remove leaves from the bottom node so it sits bare in water or soil. Submerged or buried leaves rot and foul the rooting environment. Keep the top leaves to fuel growth.
- 4Optional: apply rooting hormone
For woody or slow plants, dip the cut end in rooting hormone powder or gel and tap off the excess. It speeds rooting and helps fend off rot at the wound.
- 5Place in water or moist mix
Set the cutting in clean water with the node submerged, or insert it into a pre-moistened airy mix with the node buried. Give it bright, indirect light at 70-75 F.
- 6Maintain and pot up
Change water every few days, or keep soil lightly moist under a vented cover. When roots reach 1-2 inches (water) or a tug meets resistance (soil), pot up into well-draining soil.
Find the node every time
The node is the knuckle on the stem where a leaf attaches; you'll often see a small bump or a stub of an aerial root there. The space between nodes is the internode, and it has no ability to root. Always make your cut so the node stays on your cutting.
Aim for a cutting with one or two nodes plus a couple of leaves above them. Cut about 1/4 inch below the lowest node with sharp, clean scissors, then strip any leaves that would sit in water or soil so only a bare node goes below the surface.
Water versus soil rooting
Water rooting lets you watch progress and is forgiving for fast plants like pothos and philodendron, but the roots are water-adapted and must convert when you pot up. Soil rooting hides the process but produces sturdier, soil-ready roots from the start.
Either way, warmth (70-75 F), bright indirect light, and humidity speed things along. For woody or stubborn plants, dip the cut end in rooting hormone and root in a light, airy mix under a humidity cover for the best odds.
- Take cuttings in spring or summer when plants root fastest; winter cuttings are sluggish.
- A cutting with more nodes has more chances to root, but two or three is plenty.
- Cut just below the node, not in the middle of the internode, to minimize rotting stem below the roots.
- If a leafy cutting wilts, raise humidity with a cover rather than adding more water to the roots.
FAQ
What is a node and why does it matter?
A node is the point on a stem where leaves and aerial roots emerge, usually marked by a small bump. Roots can only form from a node, so a cutting must include at least one to ever grow into a plant.
How long is a good stem cutting?
A 4-6 inch tip cutting with one or two nodes and a few leaves is ideal. Long enough to support itself with leaf energy, short enough that the small node system can supply it.
Should I let the cut end dry before rooting?
For most tropical plants, no — root them fresh. Only succulents and woody, sap-heavy cuttings benefit from callusing the cut end for a day or two before planting.
