Eucalyptus plants are drought-tolerant, preferring well-drained soils. They can tolerate frost, although younger plants may need protection during extreme cold.
Eucalyptus plant propagation can be achieved through the use of seeds, cuttings, or by grafting. Propagation using cuttings provides a quicker method for obtaining new, identical plants. The best time to take eucalyptus cuttings is during the warmer months when the plant is actively growing.
Propagating eucalyptus from cuttings involves several steps:
- Selecting plant material: Choose healthy, pest-free stems with a diameter of about 0.25 inches, and at least two leaf nodes present.
- Preparing cuttings: Use a clean, sharp knife or pruner to make a straight cut about 4-6 inches down from the tip, just below a node. Remove all but the topmost leaves and trim any flowers or buds.
- Rooting hormone treatment: To promote faster root development, dip the cut end of the stem in a rooting hormone powder or gel.
- Planting the cuttings: Place the prepared cutting in a pot filled with a well-draining rooting medium, such as a mix of sand, perlite, and peat moss. Keep the soil moist but not waterlogged.
- Providing the right conditions: Eucalyptus cuttings require a warm, humid environment for successful root development. A good method is to cover the pot with a plastic bag and place it in a protected area with indirect sunlight.
Carefully monitor the cuttings for signs of root growth, which can take anywhere from two weeks to several months. Once root development is evident, transplant the young eucalyptus plant into a larger container or a suitable location in the garden.

Identifying Suitable Eucalyptus Cuttings
Potential Cutting Zones
To successfully propagate eucalyptus from cuttings, it is crucial to select the right cuttings. Focus on areas of healthy growth, specifically from the lateral branches. It is recommended to look for semi-hardwood cuttings, which are typically found on the middle section of the branch. These cuttings will have partially matured wood and can be identified by their slightly firm texture and greenish-brown color. Avoid using soft, green tips, as they are generally less successful in rooting.
Timing is essential when collecting eucalyptus cuttings. The best period to take cuttings is during the late summer or early autumn, when the temperatures are still warm but not too hot. This ensures that the cuttings have enough time to establish roots before the winter season. It’s also wise to take cuttings in the morning, preferably after the dew has dried, as this helps prevent wilting and the spread of diseases.
Sizing Your Cuttings
The dimensions of your eucalyptus cuttings are crucial to their survival and growth. Aim for cuttings that are about 4-6 inches (10-15 cm) long, with a diameter of approximately 1/4 inch (6 mm). This size allows for a balance between adequate rooting potential and ease of handling. When cutting, use a sharp, sterilized pair of pruning shears to make clean, diagonal cuts just below a leaf node. Remove the majority of the leaves from the lower portion of the cutting, leaving only three to four leaves at the top. This not only minimizes water loss but also encourages the development of new roots.
By following these guidelines on identifying suitable eucalyptus cuttings, including focusing on potential cutting zones, timing, and sizing your cuttings, you will increase the chances of successful propagation and enjoy the beauty and benefits of eucalyptus in your landscape.
Preparing the Cuttings
When preparing eucalyptus cuttings, select healthy, semi-hardwood stems that are approximately 6 inches in length. The ideal time for taking cuttings is during the early morning or late afternoon when the plant’s moisture levels are at their highest. Remove any leaves from the bottom two-thirds of the cutting, as this will prevent excess moisture loss and encourage root development. Make a clean, diagonal cut just below a node at the base of the stem. This helps increase the surface area for rooting and improves water and nutrient uptake.
To promote successful root growth, it’s essential to use a rooting hormone, either in liquid, powder, or gel form, before planting the eucalyptus cuttings. Following the product’s instructions, carefully dip the cut end of the stem into the rooting hormone, ensuring an even coating. Gently tap any excess rooting hormone off the cutting prior to planting. Using a rooting hormone increases the likelihood of successful rooting and helps the cuttings establish a robust root system more quickly. After treating the cuttings with rooting hormone, plant the stems in a well-draining potting mix, ensuring the cut ends are buried at least 2 inches deep. Keep the planted cuttings in a warm, humid environment, and make sure to provide adequate light and moisture. With proper care, eucalyptus cuttings will develop roots within several weeks.
