Geranium (Pelargonium) Cutting Propagation Methods and Best Time Explained

The best time to propagate geraniums by cuttings is in spring and autumn. The top shoots make the best cuttings and should be about 10cm long. Leave the cuttings in a ventilated spot until the cut surface dries, then soak the base of the cuttings in 0.01% indoleacetic acid solution for 2 seconds. After that, they can be inserted into the rooting medium. With good care and management, they will root in 2-3 weeks.

Methods and Timing for Propagating Geraniums by Cuttings

1. Cutting Time

Geraniums like to grow in a warm environment, and they enter dormancy in hot weather. So, judging by their growth habits, the best time to take cuttings is in spring and autumn each year. This allows them to root quickly and ensures a good survival rate. If cuttings are taken in summer, the cuttings are prone to rot.

2. Shoot Treatment

To propagate geraniums by cuttings, you need to choose suitable shoots, with the top shoots being the best. Cut a section of shoot about 10cm long from the mother plant as the cutting, then leave it in a ventilated spot to let the cut surface dry. Before inserting the cutting, you can also soak the base in 0.01% indoleacetic acid solution for 2 seconds, which is even more helpful for rooting and survival.

3. Cutting Care

Insert the treated shoots into a sand bed or a mixed medium of expanded perlite and peat. After that, keep the medium slightly moist and place the plants in a semi-shaded, ventilated spot. During this period, keep the temperature between 13-18°C. They will root in about 2-3 weeks, and once they are growing steadily, they can be transplanted and planted out.
