Making semi-ripe cuttings during late summer is the optimal method for free magnolia tree propagation.
The warm, sunny days of summer are not just a time for enjoying the beauty of evergreen magnolias, but also for boosting your tree collection by learning how to take cuttings. With the right timing and techniques, you can successfully propagate these plants in August, as the new growth is still green and flexible.
The Ideal Time for Cuttings
To propagate evergreen magnolia trees in August, the recommended method is to take semi-ripe cuttings from the current year’s growth. This is the best time because the new growth is still green and flexible, not yet fully woody, which increases the chances of successful rooting[1]. Ideally, take cuttings in late summer, ideally in August, during a mild, cool part of the day such as a morning[1].
Selecting and Preparing Cuttings
Choose semi-ripe shoots that are about 10-15 cm long[1][3]. These should be healthy and free from disease. Cut just below a node (where leaves attach to the stem). Remove the lower leaves but leave two or three at the top. If leaves are large, reduce their size to minimize moisture loss[3].
For optimal results, use rooting hormone by dipping the base of the cutting in a rooting powder or gel[3]. This optional step can improve the success rate.
Planting and Care
Prepare a pot with a light, well-draining compost or propagation mix, moisten it, then insert the cutting. Firm the soil around it to ensure good contact[3]. Keep the cuttings in a humid, shaded area with indirect light to prevent drying out. Mist regularly or cover with a plastic bag to retain humidity but allow some ventilation[1].
Maintain moisture and wait patiently as rooting can take several weeks. It's important to remember that magnolia grandiflora can be tricky to root from cuttings, and it might take a few months (maybe more than six) to spot signs of roots[1].
Other Plants for Late Summer Propagation
Evergreen magnolias are not the only plants suitable for propagation during late summer. Other plants like penstemons and lavender can also be propagated using similar methods[2].
Resources for Rooting Hormone
Rooting hormone powder can help with the development of roots for magnolia cuttings. It can be found on Amazon or at garden centres[3].
The Iconic Southern Magnolia
The most famous magnolia is the southern magnolia, or Magnolia grandiflora, found in the southeastern United States. This evergreen tree is known for its elongated glossy leaves and big, creamy blooms[4].
In summary, take late summer semi-ripe cuttings around 10-15 cm from healthy branches on a cool morning, use rooting hormone and well-drained soil, keep humidity high, and provide indirect light for the best chance of success[1][3]. This method is economical and effective compared to seed propagation, which is slower[1][3][5]. Happy propagating!

Incorporating home-and-garden lifestyle, late summer is a perfect time to boost your garden collection by propagating evergreen magnolias and other plants like penstemons and lavender. The ideal method to propagate evergreen magnolia trees is by taking semi-ripe cuttings from the current year's growth during a cool morning, similar to gardening practices.
