Plant propagation by cuttings is a simple and effective way to multiply plants identically, without seeds or grafting. Whether indoors or in the garden, it’s an accessible technique that enhances your interior design and landscaping. Below you’ll find clear and practical tips to propagate plants in soil and water, from a landscape architect’s perspective.
Why choose propagation by cuttings?
- Quickly obtain new plants identical to the parent plant.
- Reduce costs: all you need is a container, light substrate, and sharp scissors.
- Works for both indoor plants and ornamental shrubs or hedges in the garden.
- High success rate with common species (geranium, laurel, rosemary, mint).
Beyond the savings, propagation by cuttings is part of a sustainable approach — perfect for densifying borders, creating aromatic edges, or greening terraces and balconies.
Soil cuttings: a simple and effective method
Soil propagation consists of taking a healthy stem and rooting it directly in a light, airy medium. Geraniums are a great place to start.
Key steps for successful soil cuttings
- Select a vigorous, flower-free stem from a healthy parent plant.
- Remove the lower leaves, leaving 2 or 3 nodes bare at the base.
- Prepare a small pot with fine, well-draining substrate, leaving about 2 cm at the top.
- Make a small pilot hole (with a pencil), insert the stem, and gently close.
- Press lightly with your fingers and water with a gentle shower.
- Place in a bright but indirect light location, sheltered from wind.
Landscape tip: Keep the soil slightly moist but never waterlogged. A small greenhouse or transparent dome helps maintain humidity and speeds up root development.
Water cuttings: educational and visual
Water propagation works wonderfully for aromatic and decorative plants. Mint is a perfect example: it roots quickly, perfumes the home, and can later be transplanted into the garden.
Key steps for successful water cuttings
- Cut a young, flexible stem just below a node (where roots will sprout).
- Remove the leaves from the submerged section to avoid rot.
- Place the stem in a transparent glass or jar with 4–5 cm of low-lime water. For more seasonal plant ideas, check out our article: Winter plant selection tips.
- Keep in a bright spot away from direct sunlight and change the water when cloudy.
- When roots are 3–5 cm long, transplant into a pot or directly into the soil.
Expert tip: Mint spreads easily. Grow it in pots (even buried) or define clear borders to keep it under control.
Common mistakes to avoid
- Taking cuttings from weak or diseased parent plants.
- Leaving leaves submerged (risk of rot).
- Waterlogging the soil (root asphyxiation).
- Placing cuttings in direct sunlight (drying out).
- Neglecting to clean tools and containers (sanitize scissors and rinse jars).
A landscape architect’s perspective
Integrated into a broader design project, propagation by cuttings is a smart, low-cost way to densify terraces, balconies, or Mediterranean gardens. It helps create a coherent plant palette, staggered blooms, and responsible resource management. It’s a creative tool for structuring outdoor spaces, from planting plans to final layouts.
Observe, water regularly, and favor soft light. Whether in soil or water, propagation by cuttings is an ecological, rewarding gesture
