What To Know
- Dip the cut end of the cutting into the water and secure it with a toothpick or string.
- Make a hole in the mix with a pencil or chopstick and insert the cutting.
- Start by placing the pots outdoors in a shaded area for a few hours each day, gradually increasing the exposure time over the course of a week or two.
Mock orange, also known as Philadelphus, is a captivating shrub renowned for its heady fragrance and showy white blooms. Propagating mock orange from cuttings is a rewarding and straightforward technique that allows you to create new plants for your garden or share with friends. This comprehensive guide will empower you with the knowledge and skills to successfully grow mock orange from cuttings.
Choosing the Right Stems
The first step in successful cutting propagation is selecting suitable stems. Choose healthy, non-flowering stems with a diameter of about 1/4 inch. Cuttings from new growth, typically taken in late spring or early summer, are more likely to root.
Preparing the Cuttings
Using sharp, clean shears, make a clean, angled cut below a leaf node. Remove the lower leaves, leaving about 2-3 sets of leaves on the cutting. This will reduce water loss and encourage root development.
Rooting the Cuttings
There are two primary methods for rooting mock orange cuttings: in water or in potting mix.
Rooting in Water
Fill a glass or jar with room-temperature water. Dip the cut end of the cutting into the water and secure it with a toothpick or string. Place the container in a warm, well-lit location out of direct sunlight. Change the water every few days to prevent rot. Roots should develop within 2-4 weeks.
Rooting in Potting Mix
Fill a small pot with a well-draining potting mix specifically designed for cuttings. Make a hole in the mix with a pencil or chopstick and insert the cutting. Firm the mix around the base of the cutting to ensure good contact. Water the cutting thoroughly and keep it moist but not soggy. A rooting hormone can be applied to the cut end to promote faster root development.
Maintaining the Cuttings
Whether rooting in water or potting mix, keep the cuttings in a warm, humid environment. A plastic bag or humidity dome can be placed over the container to create a mini greenhouse effect. Monitor the cuttings regularly and water as needed to keep the mix moist but not waterlogged.
Transplanting the Rooted Cuttings
Once the roots have reached a length of about 2 inches, the cuttings are ready to be transplanted into individual pots. Use a potting mix that is well-draining and rich in organic matter. Water the cuttings well and gradually expose them to outdoor conditions over the course of a few weeks.
Hardening Off the Cuttings
Before planting the mock orange cuttings in their permanent location, they need to be hardened off. This process involves gradually exposing the plants to outdoor conditions to reduce transplant shock. Start by placing the pots outdoors in a shaded area for a few hours each day, gradually increasing the exposure time over the course of a week or two.
Planting Your Mock Orange
Choose a sunny or partially shaded location with well-drained soil. Dig a hole twice the width of the root ball and just as deep. Place the mock orange plant in the hole and backfill with soil, firming it around the base of the plant. Water the plant thoroughly and mulch around the base to retain moisture.
Wrapping Up: Nurturing Your Mock Orange
Growing mock orange from cuttings is a rewarding experience that allows you to enjoy the beauty and fragrance of this beloved shrub. By following the steps outlined in this guide, you can successfully propagate new plants and add a touch of elegance to your garden.

About 1-2 inches deep, with the lower leaves removed.
4. How long does it take for mock orange cuttings to root?
Usually within 2-4 weeks, depending on the method used and the conditions.
5. Can I use cuttings from flowering stems?
No, non-flowering stems are more likely to root successfully.
6. How can I prevent damping off in my cuttings?
Use a well-draining potting mix, avoid overwatering, and provide good air circulation.
7. How often should I fertilize my mock orange cuttings?
Once they have rooted and are actively growing, fertilize them monthly with a balanced fertilizer.
8. Can I overwinter mock orange cuttings indoors?
Yes, if they are kept in a cool, well-lit location.
