The Right Time and Key Points for Propagating Small Osmanthus (Sweet Olive) Seedlings by Cuttings

Many flower lovers see osmanthus on the roadside and think about propagating it themselves by cuttings. In this article, we will look at a detailed illustrated guide to the osmanthus cutting method. With pictures and text, it is easier for flower lovers to understand, and we hope all flower lovers can successfully propagate osmanthus.

1. First, understand the cutting time for osmanthus. For osmanthus cuttings, May and June are best. The rooting temperature for osmanthus is 25°C to 28°C. If the temperature is too low, cover with plastic film, increase light, and raise the seedbed temperature. If the temperature is too high, pay attention to shading, and lift a corner of the plastic film to ventilate and cool it down or spray water to cool it down.

The above is the best time. If flower lovers miss this time, they should pay attention to properly controlling the temperature.

2. For selecting branches, we had best not choose branches from the previous year, but instead use new semi-lignified branches of the current year, as this helps rapid rooting. Completely lignified branches are not incapable of surviving, but they root more slowly and have a lower survival rate. Cut them into lengths of 10 cm to 12 cm, cut the lower end close below a node into a horseshoe shape, and leave 2 to 3 leaves at the upper end.

3. For the cutting medium, pure perlite can be used, but note that if only perlite is used, be sure to cover with film, because moisture evaporates easily. Other media can also be used, such as sand, peat, and so on.

4. Generally, cuttings can root in about 30 days. When taking cuttings, we should not use a fertile medium; it is best to use plain soil, such as pure sand, perlite, and so on. In addition, after rooting and potting up, still do not use a medium that is too fertile, because new roots cannot withstand fertilizer, which is unfavorable for root development and survival.

ps: When potting up, note that using a large pot for small seedlings is not good; the potting soil does not dry easily, and root rot is likely. It is recommended to use a pot with a 20 cm diameter, planting 2 seedlings per pot, separated in the middle so that fewer roots are damaged when dividing the pots later.
