How to propagate your houseplants

Propagation methods

In this section, you’ll learn about the most popular propagation methods, each with clear and practical steps, so you can choose the most suitable technique for each of your plants. For best results, propagate during the active growing season (spring and summer) when plants have more energy for root and shoot development.

Stem cuttings

Stem cutting is the most common propagation method and works well for vining and stemmy plants like pothos, philodendron, monstera, and many others. While cuttings can root in soil, water propagation is usually more beginner-friendly, making it the recommended option for most.

How to propagate from stem cuttings in water

• Use clean scissors to cut a healthy stem below a node (2-3 nodes total).
• Remove lower leaves and place the stem in room temperature water.
• Keep in bright, indirect light and change the water every few days.
• Transplant when roots reach 2.5-5 cm (1-2 inches).

How to propagate from stem cuttings in soil

• Use clean scissors to cut a healthy stem below a node (2-3 nodes total).
• Optionally, dip the cut end in rooting hormone to boost success.
• Plant in moist, well-draining soil with at least one node buried.
• Keep in bright, indirect light and maintain light moisture.
• Tug gently after 3-4 weeks to check for roots.

Leaf propagation

Leaf propagation works for plants that grow new roots and shoots from a single leaf or section, like succulents, snake plants, and African violets. Some need the leaf blade, while others require the leaf with its petiole (leaf stem). Though it takes longer, this method suits plants that don’t root easily.

How to propagate from leaf cuttings

• Gently twist off a full, healthy leaf (or cut with clean scissors).
• Let it callus for 1-3 days.
• Place on dry, well-draining soil and mist lightly.
• Roots and shoots form in 2-3 weeks, while the old leaf gradually withers.

How to propagate from leaf-petiole cuttings

• Cut a leaf with 2.5-5 cm (1-2 inches) of petiole.
• Place the petiole in moist soil at a slight angle, or suspend it in water so only the tip touches.
• If using soil, cover with a loose plastic dome or bag for humidity.
• Plantlets emerge in 3-6 weeks.

Division

Division is best for plants that grow in clumps or have multiple stems, like peace lilies, ZZ plants, and spider plants. It involves separating the root ball into sections with roots and shoots, creating independent plants. This method is ideal for mature plants that have outgrown their pots.

How to propagate by division

• Remove the plant from its pot gently.
• Separate the root ball by hand or with clean scissors.
• Ensure each section has both roots and stems.
• Repot each in fresh soil and water well.

Air layering

Air layering is a method for propagating woody plants like rubber trees, fiddle leaf figs, and dracaenas. It involves wounding the stem, applying rooting hormone, and wrapping it with moist sphagnum moss. Once rooted, the new plant can be separated and potted.

How to propagate with air layering

• Make an upward cut 1/3 into the stem, 30 cm (12 inches) from the tip.
• Insert a toothpick to keep it open and apply rooting hormone.
• Wrap with moist sphagnum moss, cover with plastic, and secure.
• After 4-8 weeks, cut below the roots and pot the new plant.

Troubleshoot

Propagation doesn't always go perfectly. Even with the best techniques, you might encounter issues like rotting cuttings, lack of root development, or wilting. Understanding common problems and their solutions can help you quickly get your propagation efforts back on track.

Rotting cuttings

• Problem: Cuttings turn brown and mushy.
• Solution: Ensure proper drainage, change water frequently in water propagation, and don't overwater soil cuttings.

No root development

• Problem: Weeks pass without visible roots.
• Solution: Check for proper light (bright indirect), maintain temperatures between 18-24°C (65-75°F), and ensure the cutting includes nodes. Be patient though, sometimes roots just take their time.

Wilting cuttings

• Problem: Cuttings wilt even with proper care.
• Solution: Increase humidity by misting or using a plastic bag tent, and reduce leaf surface area by trimming larger leaves.

Mold growth

• Problem: White fuzzy mold appears on soil or cuttings.
• Solution: Improve air circulation, reduce humidity slightly, and consider treating with a fungicide if necessary.
